Dang Jason, you really thought this through. I like the flexibility that you built in to your electrical panel setup. I also like that you can easily swap out for future power station acquisitions, as technology improves or the current solar generators wear out. Very nice
I did a similar setup last November with the AC200P and 2 B230 expansion batteries. At the time I was having solar panels installed on my roof so I had the installers add 2 additional panels to the array but not tied into it. They are run along the same route for the main array but hook into my Bluetti. The two panels are 405 watt each. The AC200P can only accept up 2 700 watts but I frequently show 725 watts going in. In order to get more out of the system than just emergency power I charge the batteries during the day and run of them at night after I get home from work during the week. On the weekends I run off of the batteries during the afternoon and as long as I have good sun my solar panels easily keep up with my power needs further cutting down my electrical consumption from the power company.
I use nearly this same setup for TOU (Time Of Use) Billing from my electric company. For 4 hours of the day they raise the rates 5X base rate so I run off battery!
Thank you for the inspiration! Just picked up our transfer switch using your link as a thanks. We have an AC300 with an extra b300 and an AC 200p that we have been using via power cords. While it works fairly well, we definitely were not using our set up to the fullest. This is an awesome solution. We initially wanted to use the Bluetti sub panel but this gets us started without spending another $1500.
Great video! I have a very similar setup. I used a Reliance 10 circuit transfer switch and I also installed a 30amp inlet near my ac300 that goes to a 30amp breaker in my main panel that is controlled with a safety interlock. That way if there is some other circuits in the house that i need to power during an outage I can easily switch from using the transfer switch to plugging into the 30 amp inlet and flipping the interlock. Another benefit is I could use my gas generator by running my 50 foot cable from my generator, through a small basement window and plug that into the inlet.
In hindsight I think I should have gone with the 10 circuit transfer switch. I have a lot of low power circuits that could have benefited from running off solar most of the time. Live and learn I suppose. Thanks for sharing your interlock switch idea, pretty cool thinking :)
@chrisladd5392 I just stumbled across this video and read your comment. I’m currently installing the 10 circuit box and I too went with a transfer switch on my main panel so that my gas generator can be an additional backup. I’m glad someone else had the same thought process as me! I’m using an MPP Solar 2424LV-MSD which has a 110v inlet so it can charge off of the gas generator (at a lower amp setting than normal) while it is running if needed. When it gets late, I can shut the gas generator off and run in battery throughout the night.
I have a Bluetti AC200P, EB150, EB55, and AC50S that I purchased to power various items in the house in case of power outage. Then about 9 months ago, I became aware of these transfer switches. Wow, one box to power everything that I need to run with just 1 solar generator. I plan to install a 6 circuit one this summer. As I would hook up the AC200P to this, the only need I would have for the other solar generators is as back up batteries to recharge the AC200P. Can't count on solar input when the weather is bad, which is what likely knocked out power around here.
You got a great set of power stations Robert! Lots of power available to run things. One thing thats nice is you can at least run a gas genny to charge up power stations to store power for later use, then it's not running 24/7 using more gas. Without the batteries youd be running the generator non-stop for fridges and such. I have a 2000 watt generator I plan to use if solar isn't around to charge these up. I LOVE seeing 1000+ watts of solar but I can't get that all the time :(
I got a 50 amp transfer switch for our Jackery setup. Explorer 2000 Plus x 2 + 8 kWh total charge capacity with LiPo4 batteries. 6000 watts. Jackery is doing it best right now.
I installed the same one you have shown here. It was used by Nature Generator Elite system that I have in the back of our house. We have gone through several SCE power outage days since last year. This works out very well.
For most panel you can get a lock out it means that to turn on your auxiliary power supply the main power switch must be off the unit can then be slid past the main shutoff switch locking it off as long as the auxiliary power switch is turned on likewise as long as the main breaker is on the auxiliary power switch cannot be turned on the advantage of this unit is all circuits are available so if you have the watts to run the load you can use the item maybe can't run everything at once but shutting off the fridge freezer or furnace for an hour won't cause a problem for a 120 volt unt it means that both legs of the panel box are on the same 120 leg same as when your electricity provider put a limiter on inplace of your meter except their's limits you to enough power to run any furnace so for those with natural gas it'll usually run a 100 watt incandescent light before tripping off I'll be putting one on my auxiliary panel box and since neither my store or dryer plug is in use I'll use one of them I want to see if my 2000 watt solar generator will not run my house if it will I'll cut the grid till December and then cut it off again at the end of January will save me 1200dollars plus energy usage around 2000 dollars or more and keep my line in
i just got my transfer switch installed finally no more extention cords all over the place. powering almost everything in my house. I have 3 batteries connected to my Ac300. saving up for a 4th.
@@AskIveSolar I didn't know your main box was too old. My house was built in 78' and it's fine. I think any house with circuit breakers would work with this setup. Hit me up on Instagram with more details.
I'm here bc of @Asklve Solar! Thanks for recommending me here... And to the creator of this video, thanks for the information. Very nice presentation 👏.
Having the ProTran 10 breaker unit installed tomorrow. I have2 AC200Max’s and an AC500 with extra battery on order. Can’t wait to get this thing working.
I installed the same transfer switch for a gas generator. But now seeing I can get an AC300 and solar and use the transfer switch daily like you. And if I run out of battery power can easily plug the gas generator back into the transfer switch. Or use the gas generator to recharge the AC300 during the day and use the AC300 at night and not disturb the neighbors with a noisy gas generator or call attention to myself. Thanks for the simple walkthrough!
That's exactly my plan and on a sunny day I can run all 6 Circuits off solar no issues. When night comes around I only run my fridges to conserve battery power. With two fridges and cloudy days you'd really want to look into a second 3072wh battery
@@Jasonoid You called it. I had a 9 hour Sat without power due to storm, downed power lines. (Unusually long time) I used the AC300 with 1 B300 then had to use the gas generator. (it was a cloudy day) So now I am thinking about a second B300 like you said. But in the end I had power to get me through the day, and did not lose any food in the frig! I am enjoying learning step by step. Thanks
Nice set up. I'm building a house and just purchased the Bluetti AC500 with 2 batteries, and 420 watts of solar. Not much solar but enough to get me started and these are the portable panels so I can take all this with me in my 5th wheel. I'm going to have the electrician wire the house for generator backup (I did this myself on our last house using the same transfer switch you used), but have the generator plugged into the Bluetti AC500, along with plugging the solar into the Bluetti. I'm also on a grid, so I may have a plug in from the AC power to the Bluetti so I can charge it if the Solar can't keep up, basically using the AC500 as a UPS. I'm looking to put all of my house on the transfer switch through the Bluetti, and when I get more solar panels I'm hoping I'll be able to keep my grid power bill to a bare minimum = powering my well pump, and woodworking shop (220 outlets). Maybe if this all works well I'll get a second AC500 and get 220 working but that's for a later date.
Very Interesting Video! I have a very similar setup for my Bluetti AC200Max w/ extra B300 battery. During my research I never found this Huntkey transfer switch. I'm 100% positive that it is made in USA by Reliance Controls, but not one that they show on their website. I purchased the Reliance 306A which is designed for a generators using 30 Amp L14--30 four wire plug. It's designed for a generator with 240V capability that obviously doesn't work for 120V invertor. I ended up purchasing a short adaptor cable to plug into Bluetti 30 Amp RV outlet that connects both the hot conductors of the L14-30 and am using a 10 ft. L14-40 cord. It functions the same, but was extra work and bit of extra cost. I wish I found this switch first. Thanks for sharing this with others. Huntkey/Nature General must have seen this market need and worked with Reliance Controls to create a different model for inverter applications.
Hi Dehn, I need to do something similar for my AC500 connected to my house. I do not have grid power and will be using an inlet box plugged directly into the main breaker. What is the adapter cable you bought that allowed you to use a 120V receptacle on the 240V transfer switch?
@@benjaminramey3593 search for this: Parkworld 885446 NEMA TT-30P to L14-30R adapter cord, RV 30A TT-30 Male to Generator 4-prong 30A L14-30 Female Receptacle.
I tested out the OhNoNo cord on my channel on a single circuit. I know if the AC200p detects a live circuit it won't work. I can't say there isn't some bleed on the neutral like you were worried about because I didn't do that much testing.
I have (4) 1408Wh power stations (110V 15A). Each can connect to a backup battery, but I just connect a pair of power stations together using the cp3500 cable. That will give me 2 pairs each with 2816Wh. In each pair, both power stations can be charged individually at the same time, and have power pulled from both while having one of them connected to the L14-30 generator inlet box using a specially wired adapter. I power both legs of the panel at the same time (240V breakers are off) from one pair of power stations. The other pair is a backup. I was thinking of building a "Y connector" and connect each pair to a leg in the panel. The ground and neutral are bonded in the main panel and I have the interlock kit.
The advantage of this setup is that you can run an inverter generator in short intervals to recharge your battery banks, yet the house can enjoy 24x7 coverage. I say inverter because I wouldn’t want to damage the battery banks. People waste a lot of fuel running generators constantly when the needs of the house are low or changing throughout the day. I see a generator (especially nice if you set it up for propane or natural gas) still having a role for the occasional recharging, but the battery banks are a super way to feed essential systems. If the batteries fail, then just pass the generator directly to the transfer switch.
That's our set up. We have a Tri-Fuel generator, that runs off our homes NG line. In the event of a power outage, we use our Power Station connected to a six and ten circuit Transfer Switch. When the power station needs recharging, I start up the generator and charge the Power Station, while suppling power to all the circuits in the Transfer Switches.
@@zigzagluck I checked on my local city's website and didn't see anything about permits for a small project like this. You may be in an area that's more strict. Usually the permit is under $100 for something like this.
My electrician just added some solar 50amp breakers to my main panel and a flip switch to turn off the grid power and flip on the Solar Power. It was a simple hook up and I didn’t have to have a separate panel. This way I can choose which breakers to use, without having any limitation’s on the whole house. Very inexpensive!
@@Jasonoid I have a 24V/3000 Victron inverter. Should’ve put in a 48 V, but glad I didn’t because I would’ve shocked myself to death! I was learning as I went. I have four charge controllers that are Victron and 7.5 kW of PV. 9.6 kW of Battle Born Batteries. At some point I plan to upgrade to a 48 V inverter, just don’t have the money right now. I did all the work myself except for the main panel hook up.
Nice set up. Yours is the first video I've seen, showing how to fully use the power of a Power Station, to power your house. We have a similar set up, but with the Reliance six and ten circuit Transfer Switch. I installed two inlets outside, to connect our Tri-fuel generator to. (It runs off our homes NG line) Each transfer switch has an inlet, like yours, for our Power Station. I use a changeover switch that's connected to each inlet, to switch between two power sources. (Generator and Power Station.) So, we can have two power sources coming in, but only one power source is powering the circuits in the Transfer Switch. You forgot to show how the UPS function works with this set up. We have the Ecoflow Delta Pro which uses an EPS (Emergency Power Supply). While the DP is plugged into a wall outlet, it can pass the Utility power through to whatever is connected to it. (Without using the invertor or battery) When the power goes out, the DP switches over to battery power in 30ms. Meaning no power loss.
You make a good point, I could have showed the AC300 in ups mode powering the circuits and then if the power went out I'd just have the battery backup. Most of the time I'm going to try to run off the solar and batteries and try not to use line power.
Really like your setup. I have an AC200MAX with two 230 batteries. I already have a 220V transfer switch installed for my 7,500k generator. I was thinking of wiring an adapter to supply both legs so I can select which circuits want to energize. I would make sure to keep all 220 breakers off when using this setup.
Nice setup. I just got Tesla solar installed grid-tide obviously, and have built an offgrid backup battery solar array. No transfer switch yet for the offgrid setup so have been using extension cords for the loads in my basement. If the power goes out here, I’m primarily concerned about the fridges so the setup might be enough, but if I get an EV and scale the battery, I’ll likely go a similar route. Thanks!
Great video Jason, I'm going to be doing the same thing this summer. I've got a Delta Max on the way that I will be using. I also have about 15KW hours worth of batteries that I'm building to keep it charged.
15KW!!!!!!! Thats awesome John! How do you plan to integrate the batteries and the Delta Max together? Just curious since I have had similar thoughts to have lots of capacity for CHEAP!
@@Jasonoid I'm going to make a cable and plug it right into the solar input, I have a 36 V battery that I'm working on that I have used to charge my Delta Mini at 305w. A couple of them are Jehu Garcia's Powerbox and makita toolbox kits. I'm in the process right now of dismantling 16 scooter packs and cleaning and capacity testing 600 18650!s 😆 🤣 Lithium solar also did a toolbox battery, that I am seriously considering doing. I think it was 4 kW hours
Have just hooked up one in my house, with solar panels connected. Recently, we went on a trip, and street power went off. Battery power kicked on, ran my fridge and freezer, sooar charged the battery. When we cam home, all was well, didnt even have to set clocks as the were apart of circuit connected. Well, exept for the stove, as thats 220 volts. 😅
Only took me a couple hours to install, most of that was drywall cutting and measuring! The wiring is very simple and there are lots of videos out there on it.
Living in the PNW solar is not a reliable option much of the year. I currently have a EcoFlow 300 and Pecron 600 for lights out emergencies. And if necessary I can charge them with my 2500w portable generator/inverter or run a 120 line into the house. (I have (3) 20 lb. tanks of propane). For most normal storm related power issues we have a propane fireplace and gas stove as well. So considering purchasing a Pecron 3600 with 9 or 12 kw of total storage and an 8 or 10 circuit transfer switch. Wondering if you have tested your system as to how long it would last before requiring charging?
@jasonoid are you able to keep the AC charging cable plugged into the wall as a backup for the AC300 if your solar intake lowers and the battery depletes? I realize you can just flip the transfer switch from GEN to LINE but it would be nice not to have to do that and the AC300 recharges from wall automatically if it reaches 20% battery level or something like that.
Great Video Jason! I'm subscribed to and enjoy your channel. I'm a newbie to solar generators and solar charging in general so forgive me if I mess up some of the terminologies. I just purchased a Bluetti AC300 w/two B300's and plan on installing a transfer switch after seeing your video but have heard other people having an issue with the floating neutral and pass-through charging. They're saying the AC300 could be damaged while pass through charging if you don't get the right transfer switch that addresses the floating ground or neutral. A few of the recommended transfer switches were the Bluetti Smart Home Panel the Reliance X-Series neutral switching panels and the Generac transfer switch. My question are these nessasary because I see in your video you're doing pass-through charging with you Pro-Tran transfer switch, have you had any issues yet??? Thanks and keep up the interesting & informative videos!Rick
Hey Rick, the AC300 is an awesome setup, especially with two of the batteries! My mains power has the ground and neutral separated, they are not tied together in the main power box. It appears both my live and neutral tie back to the city power. I haven't had any issues charging the AC300 off of wall power while having circuits powered on my transfer switch. My home was built in the late 70s so things probably have changed with new builds. I'm not an expert electrian so someone more qualified might be able to give you a better answer.
Did you install your transfer switch? If so, what did you go with? My home was built 6 years ago and not sure what set-up I have or need to be aware of. Thanks!
Brilliant! Love watching this stuff, but I rent so I'll be thinking about how I can do this. I have used a grid tie inverter (cue all the warnings and negative comments) that has worked extremely well, so that's something I may try again. Well done Jason! Jim
love you hook up I am installing a transfer switch as well 306a1-eco pairing it with a single delta pro 120v using RV plug to transfer switch. can i use another pro to use as power to plug in the main unit into it or will that cause a any fault
Have you ever plugged the AC300 into the wall outlet to charge the battery while you are using the generator in this configuration? I heard you couldn’t because the generator uses a floating neutral and doing so would damage the generator! I’m totally confused at this point! By the way, I bought this system after watching your video! Please respond! Thanks
Thanks Jason for all your answers. I am new to the concept of backing up some of my home electrical systems especially my furnace. How is the Bluetti EP500 Pro with a built in UPS compare. I assume I still need a separate electrical panel to integrate to my home electrical system or just a dedicated breaker....thanks
To safely connect a power station to the grid you'll want to install a transfer switch. Also, for most furnaces to work you'll also need to have the neutral and ground bonded. My neutral and ground are bonded in my main panel, if your setup isn't you can always buy a neutral bonding plug.
Hey great video man👍🏼👍🏼. quick question: if that and L14-30 that is plugged into the transfer box? What receptacle is used on the end that plugs into the transfer switch? Thanks 🙏🏻.
Hey Jason thanks for the great info. Could you tell me (a) if there's a preferred way to bring the PV cable into the house (through a basement wall) and (b) if you need a disconnect switch between the panels and the bluetti?
I run my PV cables through my basement door but I would prefer to go through a wall in a more permanent setup. Using a DC circuit breaker / disconnect is also recommended. You can run a 250v 20 amp DC breaker (depending on the wiring).
Thanks for this idea! I have 24 panels in my house but no batteries... I wanted Teslas Powerwall for a long time but now I want the Bluetti AC300+B300 combo because I can keep adding later on. What is the difference between your transfer switch ($350) and the Bluetti Smart Home Panel ($1,499)? For me they look like the same type of thing 🤷🏽♂️
The transfer switch I have is a manual transfer switch. I manually have to swap it between line power or genny power. I think the Bluetti smart switch detects when the power goes out and swaps over to the AC300 automatically. Personally I'd go with the manual one so that you can run your curcuits off solar even if you have power or not.
@@Jasonoid Thanks for your response! Manual sounds better for me as well... Do you have an idea on how many of these batteries will be needed to run a house AC unit?
You'll need 240v output to run a full house air-conditioning unit. They do allow you to connect two AC300 units in series to get split phase output but there are cheaper ways to do that. Full size air-conditioning units pull BIG power so it's not super realistic to run large loads like that off solar. An AC300 with at least 1000 watts of solar could run a small 120volt window or stand alone ac unit without any issues.
@@Jasonoid I see that you have only 1 B300... I am undecided between 1 or 2. Now that you have tested it (1 battery), have you been able to run those fridges and extra rooms that you included in your transfer switch?
@@alexisgueits7684 I'm pretty frugal on my power usage. All leds in the house and very particular about what I leave running. During the day with solar input I can run all 6 Circuits with no problems and the battery stays at 98%. When it's cloudy I run both fridges during the day since I get around 200 watts of solar on cloudy days. At night I decide to run only 1 fridge off the battery and that load takes the battery down to about 50%, you could probably get away with running both two fridges at night but the battery would be near empty by morning. If you have a good day of sun scheduled for the next day probably not an issue. I haven't had 2 or 3 days of good sun yet so it's been hard to tell if I can let it do its thing without touching it. It's an experiment and just takes some testing and I haven't gotten lots of time with it yet.
Great videos Jason and rich with important facts and experience. Awesome work and thanks for sharing. I am also building a solution for the backup power but I have a twist that I would love to include in the setup. I was going to repeat your setup with a manual transfer switch powered by the Bluetti (type to be determined) and that Bluetti recharged by gas genset and solar. The twist I'm trying to work out if possible is if I can automate the use of the Bluetti during high peak hours and then switch back to grid without any manuel touch from me? I don't seem to be able to find automatic transfer switches with timers or other controls to allow this. Any ideas or should I be looking for something different? Many thanks for any suggestions
I am looking for solution, to charge power station from mains during night from main electricity line, when it is cheap, from 11pm till 8am, and the use the electricity from the power station during the day. I presume I would need some kind of a switch, which would control, when the power station should charge itself, and when it should use it's juice to power our 2 bed apartment. Any recommendations which model would be enough four our 3 people family?
The Bluetti AC500 and AC300 both have customized UPS modes that allow it to charge from the grid at scheduled times and from solar panels during the day. I haven't used that mode particularly since I charge mine fully off solar panels only.
Jason What type of transfer switch can I use if I have an AC200P and a 7500 watt gas generator? Can I get one with more than 4 circuits for when I might use the gas generator?
Can this one work with the Bluetti AC200P and/or the Ac200Max? I know Bluetti offers one of these to install to your home. But, they state it works for the AC300 and AC500. I have both the 200P and 200Max.
Why don't you connect your AC300 to the grid and set a charging level eg 30%? You could run your most important circuits all the time with vor AC 300. First your solarpower would be used (from 100% to 30%) and if there isn't enough solar and the charginglevel ist to low, the grid kicks in.
I have been using my AC500 with 3 B300s batteries connected to my transfer switch for about 7 months now. I have 1700 watts of solar connected in and its been going great! When it's sunny I can run all 6 circuits full time to save on my electric bill. When it's cloudy I can only run my two full size fridges full time.
I bought mine for super cheap on a local classified. Just depends on how into solar your local area is. Just make sure your panels don't go over 150v when connected all in series.
What gauge wire would I need to run from 4x300watt solar panels to a bluetti 300ac? Its a free standing solar array about 100ft from the transfer box. Thanks for any help!
@@snareofwisdom you'll want to reach out to electrician for your local code regulations that you'll need to follow. Most require THHN high heat wiring while going through conduit.
In this set up, how do you charge the battery directly from the grid when needed? I'm assuming the transfer switch only receives power from the battery and can't charge the battery from the line
You can either swap the circuits back to grid power and plug in the power station or you can plug in the power station into a circuit/outlet that's not powered by the transfer switch.
In our main control panel, we have a dedicated 20-amp braker with a 120V outlet for the DP. (Nothing else is on this circuit) We used one of the Transfer Switch circuits, for the DP circuit, in the Main Control Panel. This way we can charge the DP from the Grid as well as use the Emergency Power Supply (EPS) feature, of the DP.
Yippee! New subscriber here. Loved the video. I have 2 AC300 & 2 B300s. Looking to buy a 10 circuit transfer switch because I have 2 full sized Fridges & 2 full sized Freezers. (outdoor Kitchen gets 100° F tempts. during I plan on buying the Ford Lightning with extended battery. The 80 amp charger that comes with it (called Charge Station Pro) requires a 100 amp breaker. My AC300 is limited to 30 amps. Does this mean I will NOT be able to connect my AC300 to charge my EV?
You have a lot of power available! You'd need to have both the AC300s connected to get 240v, then you should be able to charge your EV, bluetti sells a series connector to connect them together, I haven't tested it or seen it in person
You can switch on and off the grid with each circuit on the transfer switch. So you can have 2 circuits running off your generator / power station and have the rest running off the grid (mix and match anyway).
Great video. Question: How can the manual transfer switch be automated, meaning I dont have to switch between LINE and GEN. The area I live I'm is rual and looses power 1-2 times a month. I travel for work, so I am not always home when power goes out. My thought, keep needed circuits for backup power on GEN and then plug the Butanni(example) into the ac power outlet, there for constantly charging the battery. Or would this be bad as it would waste each charging cycle?
If your power station has a UPS feature than it would automatically swap over to the batteries when the power goes out. So you could leave your transfer switch on GEN mode, then have your power station plugged into an outlet that has grid power. That would probably be the easiest option. I prefer to use solar charging instead of wall power. With enough solar panels you can keep this charged up all the time during the day.
Make sure you know what the max wattage is, when using UPS mode. If the wattage exceeds that, it could trigger the overload switch. If this happens, most units have to be reset manually. That means no power for those circuits connected to the Power Station. Also, it's a good idea to have the Power Station on its own 20-amp breaker and outlet. That way when you're charging the unit after a power failure in UPS mode, you won't max out the wattage output. Example: Our DP has a max EPS/UPS (Emergency Power Supply) wattage of 1800 watts. Our DP can be set 600 watts for AC charging. That gives us 1200 watts to use to power other circuits in our house. (If that makes since)
It sounds like your objectives are similar to mine. I wanted a backup power source for the critical stuff. Like you, I want to run my refrigerators and freezer on it full time. The reduction in the power bill will partially help pay for the system. I also have the AC300. I have 4 batteries. I have the system in the basement so it will have a steady temperature even if the air conditioning isn't running. My main power panel is nearby. I was under the impression that the Bluetti can't have neutral wire grounded as it is in the main power panel. Does your transfer switch also switch the neutral?
My home was built in 78 and In my main power box the neutral and ground are not bonded, maybe that's why it works? I don't have any issues running ground through my transfer switch.
Hey, I'm looking to buy a Bluetti power station with a B300 battery. Although I don't have a solar panel, I'm interested in installing a transfer switch. I have a question regarding its functionality. If I connect the Bluetti power station to the transfer switch, can I also keep it connected to charge with the grid? I intend to use it as a backup power source, similar to a UPS. Is it possible for the Bluetti power station to automatically provide power to my condo if the grid power goes out, just like a UPS does?"
I charge my power stations off solar most of the time while on my transfer switch so I don't have a ton of experience with that. I have seen a couple error messages with grounding when using a transfer switch and charging off grid power. It doesn't like having two grounds.
There is one issue I've heard people talk about which has me concerned, most solar generators have a floating Neutral, which could harm your power station if you were charging it and running things on the transfer switch at the same time.
I haven't noticed any issues with mine so far. I do run mine off solar 95% of the time. What I have found is that if you turn off the AC inverter, then start charging it off the grid, then turn on the inverter again it seems to work fine. I have had the power station alarm before if I plug it in while the AC inverter is enabled. The error is usually a voltage difference error.
@@Jasonoid people are telling me to go with the EZGenerator for that One important load you need. like a furnace, it runs one circuit but you can use it on floating neutral devices such as Solar Generators Bluetti/Ecoflow,etc
Would I be able to plug a Bluetti AC500 into an existing 30amp receptacle that has a transfer switch on our main panel? We use this for our gas generator and I don’t want to make an expensive mistake when we get our power system. Thanks!
I connect my AC300 and AC500 to my main panel via a Transfer Switch everyday (for the last 4 months). Homes are built during different time periods with different electrical setups so I can't guarantee if will behave the same as mine does. I haven't had any issues.
Hey Jason, why can’t you just wire that cable directly to the main breaker on your main switchboard? So let’s say your power goes out, you’d remove the line power from the street and wire the plug directly to your main switch.
For example I’m currently renting so I wouldn’t go to the trouble you’ve gone to in your own house. It would take me only a couple of minutes to remove the main power and wire in the battery power. Is there a problem with my thinking?
I'd recommend using an interlock or a transfer switch. I have seen people disable their main breaker to disconnect from grid power and then run a male to male suicide cable into a wall outlet but I'm not sure I'd recommend that... it's super sketchy and it only powers one leg of your split phase.
@@Jasonoid In Australia most of our residential buildings are only single phase. 3 phase on the street but only an Active and Neutral running to the house.
A 2000wh power station / battery-inverter setup would probably be the minimum to run one fridge for 24 hours. If you want to run more than one fridge you'd need to get more capacity.
I have the AC300 as well and was wondering in the manual it says 150 volts max on input DC and I have Renogy 100 watt panels. Each panel reads 22.5 volts so I have only 6 per DC1 and 6 per DC1. Any thoughts?
Jason, do you leave the solar plugged into the AC300 24/7? Did you run any conduit for the PV wires coming inside or no? I am going to run 1600W (two 800w arrays) of solar on a ground mount out back into my utility closet where I keep my AC300 and I plan on running metal EMT conduit in said closet to run the wires in. They will come out of the conduit thru a meg bushing to plug into the Bluetti. I am trying to build up the faith/confidence to have this thing running 24/7 even while I'm not home. I have the Reliance 10 circuit transfer switch and it runs all the 120V in my house. I do not ever plan to worry about running split phase for 240V. I just want the AC300 to run everything in the transfer switch 24/7 and to leave the PV plugged into the bluetti 24/7 without causing issues or burning my house down. Tell me it's all going to be ok 🤣🤣🤣
I think you have a great setup you have explained. The only other thing I would advise is using a DC circuit breaker / disconnect switch. I'd put that on your solar panel wires before they connect to the AC300. That way you can shut off the power if you need to mess with the wiring. It would also function as a circuit breaker if something goes wrong. This 250v 16 amp device would work great: amzn.to/3y5jZ6V
@@Jasonoid I have them! Forgot to mention lol two 16amp dc breakers on outside wall of house. Do you use the ac300 24/7? And do you leave the panels plugged in all the time?
@@mikeconte2022 yeah, 24/7 with solar. The AC300 / AC500 don't have any issues leaving solar connected all the time. Other power station will beep and sound alarms when solar is low at dusk and dawn, these don't 👍
@@Jasonoid You're awesome man!!! I sincerely appreciate you reaching out and answering questions on here!!! I cant wait to get mine running full time! It's a bit unorthodox lol. The transfer switch is in my garage. I ran 8/3 wire thru my attic and into a spare bedroom utility closet. An electrician pulled permits and installed the transfer switch and receptacle. The ac300 has had no issues powering all 10 circuits in the switch. But I have been unplugging it to recharge via AC wall power when it gets low. I'm dying to get my panels installed. I am just so nervous about letting this thing run 24/7 even while I'm not home. I do not want to start a fire 😬😬
Thanks for the video. I bought this transfer switch for my Bluetti 300 set up. Do I need to buy any other cables before the electrician comes to install it? Or does it come with everything I need? Thanks so much.
The transfer switch comes with everything you need, no additional wires needed for the install. You might need a cable to go from the transfer switch to the AC300, depends on the model you purchased.
@@Jasonoid You sure she doesn't need any other adapters when I look at the transfer switch and it has a four prone twist and on the Bluetti AC300 it has a three prone I was wondering the same thing?
I'm waiting on someone to make a video of hooking up a 48volt Lifepo4 battery to a Bluetti to extend the run time, I tried hooking up a lithium jumpstarter battery pack to it, (with the cigarette lighter adapter) and it charged my bluetti at a 100 something watts under the DC option, with a 48volt battery I would imagine someone could use the PV aspect of it for more watts coming in
Jehu Garcia (youtuber) has tried many attempts at expanding Bluetti power stations with external batteries. The problem is that these power stations require a communications link to the external battery so it's not a simple task. If you want a huge battery backup it's best to go full DIY
Excellent informative video. Notice you are running this from a Bluetti AC300 with B300. I can't find your review on this system, although you do have a discount code. I'm looking to buy an AC300 soon, and, would very much like to see your review.
@@Jasonoid this is the guy the encouraged me to install my transfer switch for my ac200p last winter. I'm about to get a B300 soon to hook the ac200 up to it
Jason, I have almost an identical setup with a Bluetti going to a transfer switch. I purchased some solar panels for the bluetti, but I'm wondering what else I need between the panels and the Bluetti in order to get it permitted. I'm thinking it would require fuses and a quick disconnect. Do you have any thoughts or info on this?
Permits are different for each location. I'd definitely recommend a properly rated DC circuit breaker for the main solar line. That might also count as a 'quick disconnect' switch, you might need both. Solar panels in series don't require fuses since the voltage is added up and the amperage stays within the panel max tolerance. If you are connecting panels in parallel, you'll need fuses.
Hi Jason, great video. Also would it not be a wise investment to go with Signature Solar 48 volt split phase all in one unit with a 5kWh server rack battery for a total of around $2700 instead of $3600 for the Bluetti ? The Signature Solar system would offer more options and capability than the Bluetti. I do not work for Signature Solar or have any vested interest in that company. I am only pointing this out from a value per dollar for the consumer and as a better/cheaper way to power your home. Also if you want portability you could mount that equipment on a roller cart as I know the Bluetti is portable somewhat.Let me know your thoughts. Thanks for a great channel.
That would be an EXCELLENT way to go if someone was comfortable putting together the system. A DIY build can really save on costs. I recently built a 24v system using and 'All in one' inverter like that ( ua-cam.com/video/Ksnv9IewYAY/v-deo.html ). It does take some knowledge and background to build a system like that and it just depends what someone is comfortable doing. I like both DIY and 'off the shelf' options and I try to cover both on my channel.
@@Jasonoid Thanks for your reply, I actually saw that video some time ago. You are correct Jason, it is simple but would take some effort to implement. On another subject do you want to share if your background is in EE or how did you come to be interested in solar,electrical, power systems etc? Maybe just a hobby?
This is great but what I really want is a transfer switch that will flip circuits over to power station automatically when the grid power fails. Does such a unit exist?
@@Jasonoid I haven't seen one available that isn't proprietary/ designed to work with a particular brand of automatic generator, or is intended for use in an RV. My concern with the latter is they are not approved for residential use / to code...
@@garethw001 I've seen a bunch from Generac but I've never read into if they are only compatible with their gas generators. With time we will see more options for power stations / batteries. If you go with an All in One setup like an EG4 or a Growatt unit they have built in automatic transfer switches I believe.
Looks like a nice canned food storage shelf. In the video when you switched to basement to shore power the lights actually got brighter. Was that real or a play with the camera white balance due to the flicker?
Probably the camera playing games, the voltage output is the same on the inverter as wall power and I never noticed a difference in real life. You can see the canned storage build video here: ua-cam.com/video/hSZ0Hh3urvM/v-deo.html
What I don’t get is the max current into that transfer switch is 30 amps. But there are 6 circuits at 15 or 20 amps each. Is there any chance you could max out the current when all 6 circuits are running?
You have to be watchful and manage your loads in your house or you'll overload the power station inverter and it will shut off. For example, running a toaster, a full size microwave, and coffee maker would be too much for the inverter. You could only run one or two devices at a time.
Just installed this same setup with 6 circuit transfer switch. However, it has started tripping GFCI breakers. I'm guessing this is because the AC300 is bonded internally? Have you had this issue as well?
Dang Jason, you really thought this through. I like the flexibility that you built in to your electrical panel setup. I also like that you can easily swap out for future power station acquisitions, as technology improves or the current solar generators wear out. Very nice
I did a similar setup last November with the AC200P and 2 B230 expansion batteries. At the time I was having solar panels installed on my roof so I had the installers add 2 additional panels to the array but not tied into it. They are run along the same route for the main array but hook into my Bluetti. The two panels are 405 watt each. The AC200P can only accept up 2 700 watts but I frequently show 725 watts going in. In order to get more out of the system than just emergency power I charge the batteries during the day and run of them at night after I get home from work during the week. On the weekends I run off of the batteries during the afternoon and as long as I have good sun my solar panels easily keep up with my power needs further cutting down my electrical consumption from the power company.
I use nearly this same setup for TOU (Time Of Use) Billing from my electric company. For 4 hours of the day they raise the rates 5X base rate so I run off battery!
That's a great way to save some cash, I just need a huge system for my air conditioning now haha 😉
Nice!
Where do you live?!
You have some of the most direct, non-cryptic content I've seen. I'll share your page.
Thank you for the inspiration! Just picked up our transfer switch using your link as a thanks.
We have an AC300 with an extra b300 and an AC 200p that we have been using via power cords. While it works fairly well, we definitely were not using our set up to the fullest. This is an awesome solution.
We initially wanted to use the Bluetti sub panel but this gets us started without spending another $1500.
Great video! I have a very similar setup. I used a Reliance 10 circuit transfer switch and I also installed a 30amp inlet near my ac300 that goes to a 30amp breaker in my main panel that is controlled with a safety interlock. That way if there is some other circuits in the house that i need to power during an outage I can easily switch from using the transfer switch to plugging into the 30 amp inlet and flipping the interlock. Another benefit is I could use my gas generator by running my 50 foot cable from my generator, through a small basement window and plug that into the inlet.
In hindsight I think I should have gone with the 10 circuit transfer switch. I have a lot of low power circuits that could have benefited from running off solar most of the time. Live and learn I suppose. Thanks for sharing your interlock switch idea, pretty cool thinking :)
@chrisladd5392 I just stumbled across this video and read your comment. I’m currently installing the 10 circuit box and I too went with a transfer switch on my main panel so that my gas generator can be an additional backup. I’m glad someone else had the same thought process as me! I’m using an MPP Solar 2424LV-MSD which has a 110v inlet so it can charge off of the gas generator (at a lower amp setting than normal) while it is running if needed. When it gets late, I can shut the gas generator off and run in battery throughout the night.
I have a Bluetti AC200P, EB150, EB55, and AC50S that I purchased to power various items in the house in case of power outage. Then about 9 months ago, I became aware of these transfer switches. Wow, one box to power everything that I need to run with just 1 solar generator. I plan to install a 6 circuit one this summer. As I would hook up the AC200P to this, the only need I would have for the other solar generators is as back up batteries to recharge the AC200P. Can't count on solar input when the weather is bad, which is what likely knocked out power around here.
You got a great set of power stations Robert! Lots of power available to run things. One thing thats nice is you can at least run a gas genny to charge up power stations to store power for later use, then it's not running 24/7 using more gas. Without the batteries youd be running the generator non-stop for fridges and such. I have a 2000 watt generator I plan to use if solar isn't around to charge these up. I LOVE seeing 1000+ watts of solar but I can't get that all the time :(
I got a 50 amp transfer switch for our Jackery setup. Explorer 2000 Plus x 2 + 8 kWh total charge capacity with LiPo4 batteries. 6000 watts. Jackery is doing it best right now.
I installed the same one you have shown here. It was used by Nature Generator Elite system that I have in the back of our house. We have gone through several SCE power outage days since last year. This works out very well.
Glad to hear it's working for you so well!
BOOM! This is what im talking about! Game changer on every level.....Thank you for sharing
Thanks MJ! It's easy enough for most people to do if you take your time.
For most panel you can get a lock out it means that to turn on your auxiliary power supply the main power switch must be off the unit can then be slid past the main shutoff switch locking it off as long as the auxiliary power switch is turned on likewise as long as the main breaker is on the auxiliary power switch cannot be turned on the advantage of this unit is all circuits are available so if you have the watts to run the load you can use the item maybe can't run everything at once but shutting off the fridge freezer or furnace for an hour won't cause a problem for a 120 volt unt it means that both legs of the panel box are on the same 120 leg same as when your electricity provider put a limiter on inplace of your meter except their's limits you to enough power to run any furnace so for those with natural gas it'll usually run a 100 watt incandescent light before tripping off I'll be putting one on my auxiliary panel box and since neither my store or dryer plug is in use I'll use one of them I want to see if my 2000 watt solar generator will not run my house if it will I'll cut the grid till December and then cut it off again at the end of January will save me 1200dollars plus energy usage around 2000 dollars or more and keep my line in
GOOD tip, thanks.
i just got my transfer switch installed finally no more extention cords all over the place. powering almost everything in my house. I have 3 batteries connected to my Ac300. saving up for a 4th.
That's what I like to hear! Sweet!
I hooked one up five years ago when I built my house. I’ve got the bluetti ep 500 plugged in, and ac200p for backup
Sweet setup! That's a lot of power! How have you liked it? Do you have solar panels to charge them up too?
@@Jasonoid I have 1400 watts of solar panel, I haven’t used the grid at all

This is most def the goal for me! 100%
@@AskIveSolar I didn't know your main box was too old. My house was built in 78' and it's fine. I think any house with circuit breakers would work with this setup. Hit me up on Instagram with more details.

And to the creator of this video, thanks for the information. Very nice presentation 👏.
Having the ProTran 10 breaker unit installed tomorrow. I have2 AC200Max’s and an AC500 with extra battery on order. Can’t wait to get this thing working.
I installed the same transfer switch for a gas generator. But now seeing I can get an AC300 and solar and use the transfer switch daily like you. And if I run out of battery power can easily plug the gas generator back into the transfer switch. Or use the gas generator to recharge the AC300 during the day and use the AC300 at night and not disturb the neighbors with a noisy gas generator or call attention to myself. Thanks for the simple walkthrough!
That's exactly my plan and on a sunny day I can run all 6 Circuits off solar no issues. When night comes around I only run my fridges to conserve battery power. With two fridges and cloudy days you'd really want to look into a second 3072wh battery
@@Jasonoid You called it. I had a 9 hour Sat without power due to storm, downed power lines. (Unusually long time) I used the AC300 with 1 B300 then had to use the gas generator. (it was a cloudy day) So now I am thinking about a second B300 like you said. But in the end I had power to get me through the day, and did not lose any food in the frig! I am enjoying learning step by step. Thanks
Nice set up. I'm building a house and just purchased the Bluetti AC500 with 2 batteries, and 420 watts of solar. Not much solar but enough to get me started and these are the portable panels so I can take all this with me in my 5th wheel. I'm going to have the electrician wire the house for generator backup (I did this myself on our last house using the same transfer switch you used), but have the generator plugged into the Bluetti AC500, along with plugging the solar into the Bluetti. I'm also on a grid, so I may have a plug in from the AC power to the Bluetti so I can charge it if the Solar can't keep up, basically using the AC500 as a UPS. I'm looking to put all of my house on the transfer switch through the Bluetti, and when I get more solar panels I'm hoping I'll be able to keep my grid power bill to a bare minimum = powering my well pump, and woodworking shop (220 outlets). Maybe if this all works well I'll get a second AC500 and get 220 working but that's for a later date.
Very Interesting Video! I have a very similar setup for my Bluetti AC200Max w/ extra B300 battery. During my research I never found this Huntkey transfer switch. I'm 100% positive that it is made in USA by Reliance Controls, but not one that they show on their website. I purchased the Reliance 306A which is designed for a generators using 30 Amp L14--30 four wire plug. It's designed for a generator with 240V capability that obviously doesn't work for 120V invertor. I ended up purchasing a short adaptor cable to plug into Bluetti 30 Amp RV outlet that connects both the hot conductors of the L14-30 and am using a 10 ft. L14-40 cord. It functions the same, but was extra work and bit of extra cost. I wish I found this switch first. Thanks for sharing this with others. Huntkey/Nature General must have seen this market need and worked with Reliance Controls to create a different model for inverter applications.
Hi Dehn, I need to do something similar for my AC500 connected to my house. I do not have grid power and will be using an inlet box plugged directly into the main breaker. What is the adapter cable you bought that allowed you to use a 120V receptacle on the 240V transfer switch?

Parkworld 885446 NEMA TT-30P to L14-30R adapter cord, RV 30A TT-30 Male to Generator 4-prong 30A L14-30 Female Receptacle.
I tested out the OhNoNo cord on my channel on a single circuit. I know if the AC200p detects a live circuit it won't work. I can't say there isn't some bleed on the neutral like you were worried about because I didn't do that much testing.
Interesting, thanks for the info! I'll check out the video.
I have (4) 1408Wh power stations (110V 15A). Each can connect to a backup battery, but I just connect a pair of power stations together using the cp3500 cable. That will give me 2 pairs each with 2816Wh. In each pair, both power stations can be charged individually at the same time, and have power pulled from both while having one of them connected to the L14-30 generator inlet box using a specially wired adapter. I power both legs of the panel at the same time (240V breakers are off) from one pair of power stations. The other pair is a backup. I was thinking of building a "Y connector" and connect each pair to a leg in the panel. The ground and neutral are bonded in the main panel and I have the interlock kit.
The advantage of this setup is that you can run an inverter generator in short intervals to recharge your battery banks, yet the house can enjoy 24x7 coverage. I say inverter because I wouldn’t want to damage the battery banks. People waste a lot of fuel running generators constantly when the needs of the house are low or changing throughout the day. I see a generator (especially nice if you set it up for propane or natural gas) still having a role for the occasional recharging, but the battery banks are a super way to feed essential systems. If the batteries fail, then just pass the generator directly to the transfer switch.
Great points Nate! I agree there are many ways to use a transfer switch with a combo of Generators and batteries.
That's our set up. We have a Tri-Fuel generator, that runs off our homes NG line. In the event of a power outage, we use our Power Station connected to a six and ten circuit Transfer Switch. When the power station needs recharging, I start up the generator and charge the Power Station, while suppling power to all the circuits in the Transfer Switches.
Exactly what I plan on doing later this year! Great timing Jason!
Glad it was helpful, I'm looking forward to doing some more testing and providing updates.
@@Jasonoid Did you have to get a permit from your city to install it?
@@zigzagluck I checked on my local city's website and didn't see anything about permits for a small project like this. You may be in an area that's more strict. Usually the permit is under $100 for something like this.
Wow, that that is a smart and easy set up. Will recommend to a few people looking to do this very thing.
Thanks Steve!
My electrician just added some solar 50amp breakers to my main panel and a flip switch to turn off the grid power and flip on the Solar Power. It was a simple hook up and I didn’t have to have a separate panel. This way I can choose which breakers to use, without having any limitation’s on the whole house. Very inexpensive!
Are you using rooftop solar with inverters? Sounds like a sweet setup!
@@Jasonoid
I have a 24V/3000 Victron inverter. Should’ve put in a 48 V, but glad I didn’t because I would’ve shocked myself to death! I was learning as I went.
I have four charge controllers that are Victron and 7.5 kW of PV. 9.6 kW of Battle Born Batteries.
At some point I plan to upgrade to a 48 V inverter, just don’t have the money right now. I did all the work myself except for the main panel hook up.
I would be grateful to have that setup.I have 3 power devices, largest is 1800-2000. Need a AC200 or 300 to power my freezers and fridge.
It's taken 4 years for the channel to get to this point, lots of work and it's finally paying off since I get to play with the big toys now!
Nice set up. Yours is the first video I've seen, showing how to fully use the power of a Power Station, to power your house.
We have a similar set up, but with the Reliance six and ten circuit Transfer Switch. I installed two inlets outside, to connect our Tri-fuel generator to. (It runs off our homes NG line) Each transfer switch has an inlet, like yours, for our Power Station. I use a changeover switch that's connected to each inlet, to switch between two power sources. (Generator and Power Station.) So, we can have two power sources coming in, but only one power source is powering the circuits in the Transfer Switch.
You forgot to show how the UPS function works with this set up. We have the Ecoflow Delta Pro which uses an EPS (Emergency Power Supply). While the DP is plugged into a wall outlet, it can pass the Utility power through to whatever is connected to it. (Without using the invertor or battery) When the power goes out, the DP switches over to battery power in 30ms. Meaning no power loss.
You make a good point, I could have showed the AC300 in ups mode powering the circuits and then if the power went out I'd just have the battery backup. Most of the time I'm going to try to run off the solar and batteries and try not to use line power.
Really like your setup. I have an AC200MAX with two 230 batteries. I already have a 220V transfer switch installed for my 7,500k generator. I was thinking of wiring an adapter to supply both legs so I can select which circuits want to energize. I would make sure to keep all 220 breakers off when using this setup.
I'm sure something like that would work for the AC200MAX
Nice setup. I just got Tesla solar installed grid-tide obviously, and have built an offgrid backup battery solar array. No transfer switch yet for the offgrid setup so have been using extension cords for the loads in my basement. If the power goes out here, I’m primarily concerned about the fridges so the setup might be enough, but if I get an EV and scale the battery, I’ll likely go a similar route. Thanks!
What a timely video... just bought a transfer switch, just need to install it.
Thats awesome! What will your setup be looking like?
Hey can show/ explain the solar panels ground is connected ?
Great video Jason, I'm going to be doing the same thing this summer. I've got a Delta Max on the way that I will be using. I also have about 15KW hours worth of batteries that I'm building to keep it charged.
15KW!!!!!!! Thats awesome John! How do you plan to integrate the batteries and the Delta Max together? Just curious since I have had similar thoughts to have lots of capacity for CHEAP!

Have just hooked up one in my house, with solar panels connected. Recently, we went on a trip, and street power went off. Battery power kicked on, ran my fridge and freezer, sooar charged the battery. When we cam home, all was well, didnt even have to set clocks as the were apart of circuit connected. Well, exept for the stove, as thats 220 volts. 😅
That's a huge benefit of a transfer switch. I've also saved quite a bit of money on my monthly power bill! Glad to hear the good results 😁👍
Awesome set up! This is my exact goal for my house as well.
Only took me a couple hours to install, most of that was drywall cutting and measuring! The wiring is very simple and there are lots of videos out there on it.
Living in the PNW solar is not a reliable option much of the year. I currently have a EcoFlow 300 and Pecron 600 for lights out emergencies. And if necessary I can charge them with my 2500w portable generator/inverter or run a 120 line into the house. (I have (3) 20 lb. tanks of propane). For most normal storm related power issues we have a propane fireplace and gas stove as well. So considering purchasing a Pecron 3600 with 9 or 12 kw of total storage and an 8 or 10 circuit transfer switch. Wondering if you have tested your system as to how long it would last before requiring charging?
Great video. Learned more the 2nd time I saw it . I’m trying to do a similar setup.
@jasonoid are you able to keep the AC charging cable plugged into the wall as a backup for the AC300 if your solar intake lowers and the battery depletes? I realize you can just flip the transfer switch from GEN to LINE but it would be nice not to have to do that and the AC300 recharges from wall automatically if it reaches 20% battery level or something like that.
fantastic. real life application,,,just what we need as an example. Tks Jasonoid
No problem! Simple install to keep the power on :)
Great Video Jason! I'm subscribed to and enjoy your channel. I'm a newbie to solar generators and solar charging in general so forgive me if I mess up some of the terminologies. I just purchased a Bluetti AC300 w/two B300's and plan on installing a transfer switch after seeing your video but have heard other people having an issue with the floating neutral and pass-through charging. They're saying the AC300 could be damaged while pass through charging if you don't get the right transfer switch that addresses the floating ground or neutral. A few of the recommended transfer switches were the Bluetti Smart Home Panel the Reliance X-Series neutral switching panels and the Generac transfer switch. My question are these nessasary because I see in your video you're doing pass-through charging with you Pro-Tran transfer switch, have you had any issues yet???
Thanks and keep up the interesting & informative videos!Rick
Hey Rick, the AC300 is an awesome setup, especially with two of the batteries! My mains power has the ground and neutral separated, they are not tied together in the main power box. It appears both my live and neutral tie back to the city power. I haven't had any issues charging the AC300 off of wall power while having circuits powered on my transfer switch. My home was built in the late 70s so things probably have changed with new builds. I'm not an expert electrian so someone more qualified might be able to give you a better answer.
Did you install your transfer switch? If so, what did you go with? My home was built 6 years ago and not sure what set-up I have or need to be aware of. Thanks!
Brilliant! Love watching this stuff, but I rent so I'll be thinking about how I can do this. I have used a grid tie inverter (cue all the warnings and negative comments) that has worked extremely well, so that's something I may try again. Well done Jason! Jim
I'd use a grid tie if it was legal in my area and my power company wouldn't come hunt me down lol
love you hook up I am installing a transfer switch as well 306a1-eco pairing it with a single delta pro 120v using RV plug to transfer switch. can i use another pro to use as power to plug in the main unit into it or will that cause a any fault
Have you ever plugged the AC300 into the wall outlet to charge the battery while you are using the generator in this configuration? I heard you couldn’t because the generator uses a floating neutral and doing so would damage the generator! I’m totally confused at this point! By the way, I bought this system after watching your video! Please respond! Thanks
Thanks Jason for all your answers. I am new to the concept of backing up some of my home electrical systems especially my furnace. How is the Bluetti EP500 Pro with a built in UPS compare. I assume I still need a separate electrical panel to integrate to my home electrical system or just a dedicated breaker....thanks
To safely connect a power station to the grid you'll want to install a transfer switch. Also, for most furnaces to work you'll also need to have the neutral and ground bonded. My neutral and ground are bonded in my main panel, if your setup isn't you can always buy a neutral bonding plug.
Hey great video man👍🏼👍🏼. quick question: if that and L14-30 that is plugged into the transfer box?
What receptacle is used on the end that plugs into the transfer switch? Thanks 🙏🏻.
This is the product listing on Amazon, maybe you can find more info on it: amzn.to/3yOjheL
Its a twist in lock 120v 3 prong connection.
Hey Jason thanks for the great info. Could you tell me (a) if there's a preferred way to bring the PV cable into the house (through a basement wall) and (b) if you need a disconnect switch between the panels and the bluetti?
I run my PV cables through my basement door but I would prefer to go through a wall in a more permanent setup. Using a DC circuit breaker / disconnect is also recommended. You can run a 250v 20 amp DC breaker (depending on the wiring).
Will not just use a generator inlet VS the transfer switch?
great idea... how was getting the permits to install it? wondering if something like that would help with my RV
I didn't get permits for the install, I didn't see requirements on my cities website.
Hi, I like your video. Just asking. With your setup, do you sell solar to you utility? Can this setup sell solar to your utility? Thanks.
No, this setup does not work like a net metering system. You are just using the power from your power station instead of your power company
Thanks for this idea! I have 24 panels in my house but no batteries... I wanted Teslas Powerwall for a long time but now I want the Bluetti AC300+B300 combo because I can keep adding later on. What is the difference between your transfer switch ($350) and the Bluetti Smart Home Panel ($1,499)? For me they look like the same type of thing 🤷🏽♂️
The transfer switch I have is a manual transfer switch. I manually have to swap it between line power or genny power. I think the Bluetti smart switch detects when the power goes out and swaps over to the AC300 automatically. Personally I'd go with the manual one so that you can run your curcuits off solar even if you have power or not.
@@Jasonoid Thanks for your response! Manual sounds better for me as well... Do you have an idea on how many of these batteries will be needed to run a house AC unit?
You'll need 240v output to run a full house air-conditioning unit. They do allow you to connect two AC300 units in series to get split phase output but there are cheaper ways to do that. Full size air-conditioning units pull BIG power so it's not super realistic to run large loads like that off solar.
An AC300 with at least 1000 watts of solar could run a small 120volt window or stand alone ac unit without any issues.
@@Jasonoid I see that you have only 1 B300... I am undecided between 1 or 2. Now that you have tested it (1 battery), have you been able to run those fridges and extra rooms that you included in your transfer switch?
@@alexisgueits7684 I'm pretty frugal on my power usage. All leds in the house and very particular about what I leave running. During the day with solar input I can run all 6 Circuits with no problems and the battery stays at 98%. When it's cloudy I run both fridges during the day since I get around 200 watts of solar on cloudy days.
At night I decide to run only 1 fridge off the battery and that load takes the battery down to about 50%, you could probably get away with running both two fridges at night but the battery would be near empty by morning. If you have a good day of sun scheduled for the next day probably not an issue. I haven't had 2 or 3 days of good sun yet so it's been hard to tell if I can let it do its thing without touching it.
It's an experiment and just takes some testing and I haven't gotten lots of time with it yet.
Good info and set up bro
Thanks REeP0!
do you know of a video showing how to wire in that transfer switch box?
Reliance Controls (who makes this model) has a few different install videos on their website and UA-cam channel.
So if i have an existing manual transfer switch (Emergent) I can replace my portable gas generator with an Eco Flow or Bluetti backup solutions?
It works for me
Great videos Jason and rich with important facts and experience. Awesome work and thanks for sharing. I am also building a solution for the backup power but I have a twist that I would love to include in the setup. I was going to repeat your setup with a manual transfer switch powered by the Bluetti (type to be determined) and that Bluetti recharged by gas genset and solar. The twist I'm trying to work out if possible is if I can automate the use of the Bluetti during high peak hours and then switch back to grid without any manuel touch from me? I don't seem to be able to find automatic transfer switches with timers or other controls to allow this. Any ideas or should I be looking for something different? Many thanks for any suggestions
There is a UPS mode that will allow for grid charging during specific times of the day, so you can program it to charge during off peak hours.
I have the same transfer switch. Do you flip the switch from Gen to Line daily? If so do you think that will wear out the switches sooner?
I am looking for solution, to charge power station from mains during night from main electricity line, when it is cheap, from 11pm till 8am, and the use the electricity from the power station during the day. I presume I would need some kind of a switch, which would control, when the power station should charge itself, and when it should use it's juice to power our 2 bed apartment. Any recommendations which model would be enough four our 3 people family?
The Bluetti AC500 and AC300 both have customized UPS modes that allow it to charge from the grid at scheduled times and from solar panels during the day. I haven't used that mode particularly since I charge mine fully off solar panels only.
Jason
What type of transfer switch can I use if I have an AC200P and a 7500 watt gas generator? Can I get one with more than 4 circuits for when I might use the gas generator?
Yes. Reliance Controls have a six and ten circuit Transfer Switch.
Can this one work with the Bluetti AC200P and/or the Ac200Max? I know Bluetti offers one of these to install to your home. But, they state it works for the AC300 and AC500. I have both the 200P and 200Max.
Yes, many people use the AC200 series power stations on their transfer switches. You'd be limited to the max output of the inverter.
Great video! I was just thinking about this myself.
You should! Definitely worth it!
GREAT JOB JASON
Jason, can you do this to a old house with the old fashion screw-in fuse panel, or do you need to upgrade the home panel to a circuit breaker type?
I'd probably recommend upgrading the panel to the newer removable circuit breakers. They get the transfer switch installed.
Why don't you connect your AC300 to the grid and set a charging level eg 30%? You could run your most important circuits all the time with vor AC 300. First your solarpower would be used (from 100% to 30%) and if there isn't enough solar and the charginglevel ist to low, the grid kicks in.
Hi Jason, awesome video, love it. Any updates on how this set up is working?
I have been using my AC500 with 3 B300s batteries connected to my transfer switch for about 7 months now. I have 1700 watts of solar connected in and its been going great! When it's sunny I can run all 6 circuits full time to save on my electric bill. When it's cloudy I can only run my two full size fridges full time.
@@Jasonoid Awesome, I am looking to follow your set up using the Pecron E2000LFP.
Many thanks!
As long as your total system power doesn't go over 2000 watts you'll be good. You'll want to watch the wattage on each circuit to see how things go.
@@Jasonoid thanks, will do
Any recommendations on a good place to buy 200-300 watt panels for a yard mount that will be tied in to a Bluetti 300AC?
I bought mine for super cheap on a local classified. Just depends on how into solar your local area is. Just make sure your panels don't go over 150v when connected all in series.
What gauge wire would I need to run from 4x300watt solar panels to a bluetti 300ac? Its a free standing solar array about 100ft from the transfer box. Thanks for any help!
For that distance you'd want to do 10awg wire and your panels wired in series for high voltage / low amperage.
Thanks a bunch! Do you know if I would need to use 10/2 or 10/3 wire? I assume 10/3 for the ground.@@Jasonoid
@@snareofwisdom 10/2, you would just ground the solar panels to the ground near the mount system, ground does not go into the AC300 solar input
@@Jasonoid do you know the best way to connect the panel array to the 10 gauge wire that will run through conduit to my transfer box?
@@snareofwisdom you'll want to reach out to electrician for your local code regulations that you'll need to follow. Most require THHN high heat wiring while going through conduit.
In this set up, how do you charge the battery directly from the grid when needed? I'm assuming the transfer switch only receives power from the battery and can't charge the battery from the line
You can either swap the circuits back to grid power and plug in the power station or you can plug in the power station into a circuit/outlet that's not powered by the transfer switch.
In our main control panel, we have a dedicated 20-amp braker with a 120V outlet for the DP. (Nothing else is on this circuit) We used one of the Transfer Switch circuits, for the DP circuit, in the Main Control Panel. This way we can charge the DP from the Grid as well as use the Emergency Power Supply (EPS) feature, of the DP.
Yippee! New subscriber here. Loved the video. I have 2 AC300 & 2 B300s.
Looking to buy a 10 circuit transfer switch because I have 2 full sized Fridges & 2 full sized Freezers. (outdoor Kitchen gets 100° F tempts. during
I plan on buying the Ford Lightning with extended battery. The 80 amp charger that comes with it (called Charge Station Pro) requires a 100 amp breaker. My AC300 is limited to 30 amps. Does this mean I will NOT be able to connect my AC300 to charge my EV?
You have a lot of power available! You'd need to have both the AC300s connected to get 240v, then you should be able to charge your EV, bluetti sells a series connector to connect them together, I haven't tested it or seen it in person
@@Jasonoid Pro Fusion Box. I have it! You can see it 3:36 mins. into my video.
ua-cam.com/video/90_e8I3fW4g/v-deo.html
I couldnt tell from your explanation, but can you have some circuits on solar and some on grid at the same time, or is it one or the other?
You can switch on and off the grid with each circuit on the transfer switch. So you can have 2 circuits running off your generator / power station and have the rest running off the grid (mix and match anyway).
Interesting video, thanks. But I was looking what you had to the right of the video.... Loads of can of food... Or cans and can's of beer?
Just extra food stored for rough times 👍
@@Jasonoid I have the same downstairs. But it aren't food!
Great video. Question: How can the manual transfer switch be automated, meaning I dont have to switch between LINE and GEN. The area I live I'm is rual and looses power 1-2 times a month. I travel for work, so I am not always home when power goes out. My thought, keep needed circuits for backup power on GEN and then plug the Butanni(example) into the ac power outlet, there for constantly charging the battery. Or would this be bad as it would waste each charging cycle?
If your power station has a UPS feature than it would automatically swap over to the batteries when the power goes out. So you could leave your transfer switch on GEN mode, then have your power station plugged into an outlet that has grid power. That would probably be the easiest option. I prefer to use solar charging instead of wall power. With enough solar panels you can keep this charged up all the time during the day.
Make sure you know what the max wattage is, when using UPS mode. If the wattage exceeds that, it could trigger the overload switch. If this happens, most units have to be reset manually. That means no power for those circuits connected to the Power Station.
Also, it's a good idea to have the Power Station on its own 20-amp breaker and outlet. That way when you're charging the unit after a power failure in UPS mode, you won't max out the wattage output. Example: Our DP has a max EPS/UPS (Emergency Power Supply) wattage of 1800 watts. Our DP can be set 600 watts for AC charging. That gives us 1200 watts to use to power other circuits in our house. (If that makes since)
It sounds like your objectives are similar to mine. I wanted a backup power source for the critical stuff. Like you, I want to run my refrigerators and freezer on it full time. The reduction in the power bill will partially help pay for the system.
I also have the AC300. I have 4 batteries. I have the system in the basement so it will have a steady temperature even if the air conditioning isn't running. My main power panel is nearby.
I was under the impression that the Bluetti can't have neutral wire grounded as it is in the main power panel. Does your transfer switch also switch the neutral?
My home was built in 78 and In my main power box the neutral and ground are not bonded, maybe that's why it works? I don't have any issues running ground through my transfer switch.
Does it work with Tesla solar panel
Any reason you couldn't use a six circuit transfer switch with a bluetti ac200p?
Just make sure you don't go over 2000 watts continuous and you'll be great! No issues.
@@Jasonoid Thanks Jason. Great video.
Hey, I'm looking to buy a Bluetti power station with a B300 battery. Although I don't have a solar panel, I'm interested in installing a transfer switch. I have a question regarding its functionality. If I connect the Bluetti power station to the transfer switch, can I also keep it connected to charge with the grid? I intend to use it as a backup power source, similar to a UPS. Is it possible for the Bluetti power station to automatically provide power to my condo if the grid power goes out, just like a UPS does?"
I charge my power stations off solar most of the time while on my transfer switch so I don't have a ton of experience with that. I have seen a couple error messages with grounding when using a transfer switch and charging off grid power. It doesn't like having two grounds.
There is one issue I've heard people talk about which has me concerned, most solar generators have a floating Neutral, which could harm your power station if you were charging it and running things on the transfer switch at the same time.
I haven't noticed any issues with mine so far. I do run mine off solar 95% of the time. What I have found is that if you turn off the AC inverter, then start charging it off the grid, then turn on the inverter again it seems to work fine. I have had the power station alarm before if I plug it in while the AC inverter is enabled. The error is usually a voltage difference error.
@@Jasonoid people are telling me to go with the EZGenerator for that One important load you need. like a furnace, it runs one circuit but you can use it on floating neutral devices such as Solar Generators Bluetti/Ecoflow,etc
Would I be able to plug a Bluetti AC500 into an existing 30amp receptacle that has a transfer switch on our main panel? We use this for our gas generator and I don’t want to make an expensive mistake when we get our power system. Thanks!
I connect my AC300 and AC500 to my main panel via a Transfer Switch everyday (for the last 4 months). Homes are built during different time periods with different electrical setups so I can't guarantee if will behave the same as mine does. I haven't had any issues.
@@Jasonoid Thanks! Hopefully it works so I can save a few bucks. These systems aren't cheap!
Great explanation and great tips, thanks 😊
Thanks for watching!
Hey Jason, why can’t you just wire that cable directly to the main breaker on your main switchboard?
So let’s say your power goes out, you’d remove the line power from the street and wire the plug directly to your main switch.
For example I’m currently renting so I wouldn’t go to the trouble you’ve gone to in your own house. It would take me only a couple of minutes to remove the main power and wire in the battery power. Is there a problem with my thinking?
I'd recommend using an interlock or a transfer switch. I have seen people disable their main breaker to disconnect from grid power and then run a male to male suicide cable into a wall outlet but I'm not sure I'd recommend that... it's super sketchy and it only powers one leg of your split phase.
@@Jasonoid In Australia most of our residential buildings are only single phase. 3 phase on the street but only an Active and Neutral running to the house.
My thinking is that it’s easier to simply disconnect the mains and hook the RV plug directly to the main switch
Could you do the same with an interlock kit rather than a transfer switch?
Yes! An interlock would also work
what would you consider the minimum size battery backup to make a transfer switch installation worth doing?
A 2000wh power station / battery-inverter setup would probably be the minimum to run one fridge for 24 hours. If you want to run more than one fridge you'd need to get more capacity.
I have the AC300 as well and was wondering in the manual it says 150 volts max on input DC and I have Renogy 100 watt panels. Each panel reads 22.5 volts so I have only 6 per DC1 and 6 per DC1. Any thoughts?
You can also double up on parallel connections so it would be a 6S2P array for 1200 watts total of 12 panels on each solar charge controller.
Love the setup and thank you for the video. What solar panels are you using outside?
A mixture of four BOUGERV 180w panels on the ground, three 325 watt panels on my shed.
Jason, do you leave the solar plugged into the AC300 24/7? Did you run any conduit for the PV wires coming inside or no? I am going to run 1600W (two 800w arrays) of solar on a ground mount out back into my utility closet where I keep my AC300 and I plan on running metal EMT conduit in said closet to run the wires in. They will come out of the conduit thru a meg bushing to plug into the Bluetti. I am trying to build up the faith/confidence to have this thing running 24/7 even while I'm not home. I have the Reliance 10 circuit transfer switch and it runs all the 120V in my house. I do not ever plan to worry about running split phase for 240V. I just want the AC300 to run everything in the transfer switch 24/7 and to leave the PV plugged into the bluetti 24/7 without causing issues or burning my house down. Tell me it's all going to be ok 🤣🤣🤣
I think you have a great setup you have explained. The only other thing I would advise is using a DC circuit breaker / disconnect switch. I'd put that on your solar panel wires before they connect to the AC300. That way you can shut off the power if you need to mess with the wiring. It would also function as a circuit breaker if something goes wrong. This 250v 16 amp device would work great: amzn.to/3y5jZ6V
@@Jasonoid I have them! Forgot to mention lol two 16amp dc breakers on outside wall of house. Do you use the ac300 24/7? And do you leave the panels plugged in all the time?
@@mikeconte2022 yeah, 24/7 with solar. The AC300 / AC500 don't have any issues leaving solar connected all the time. Other power station will beep and sound alarms when solar is low at dusk and dawn, these don't 👍
@@Jasonoid You're awesome man!!! I sincerely appreciate you reaching out and answering questions on here!!! I cant wait to get mine running full time! It's a bit unorthodox lol. The transfer switch is in my garage. I ran 8/3 wire thru my attic and into a spare bedroom utility closet. An electrician pulled permits and installed the transfer switch and receptacle. The ac300 has had no issues powering all 10 circuits in the switch. But I have been unplugging it to recharge via AC wall power when it gets low. I'm dying to get my panels installed. I am just so nervous about letting this thing run 24/7 even while I'm not home. I do not want to start a fire 😬😬
Thanks for the video. I bought this transfer switch for my Bluetti 300 set up. Do I need to buy any other cables before the electrician comes to install it? Or does it come with everything I need? Thanks so much.
The transfer switch comes with everything you need, no additional wires needed for the install. You might need a cable to go from the transfer switch to the AC300, depends on the model you purchased.
@@Jasonoid You sure she doesn't need any other adapters when I look at the transfer switch and it has a four prone twist and on the Bluetti AC300 it has a three prone I was wondering the same thing?
@@jamesclark144 if you use the one I purchased in the video, it came with the cable that adapts to the rv plug on the AC300
I'm waiting on someone to make a video of hooking up a 48volt Lifepo4 battery to a Bluetti to extend the run time, I tried hooking up a lithium jumpstarter battery pack to it, (with the cigarette lighter adapter) and it charged my bluetti at a 100 something watts under the DC option, with a 48volt battery I would imagine someone could use the PV aspect of it for more watts coming in
Jehu Garcia (youtuber) has tried many attempts at expanding Bluetti power stations with external batteries. The problem is that these power stations require a communications link to the external battery so it's not a simple task. If you want a huge battery backup it's best to go full DIY
Excellent informative video. Notice you are running this from a Bluetti AC300 with B300. I can't find your review on this system, although you do have a discount code. I'm looking to buy an AC300 soon, and, would very much like to see your review.
I will have the review soon, I've had quite a backlog of videos I'm trying to get through, it's been good so far! 😁👍
@@Jasonoid Thanks!
That is awesome! Nice setup.
You got a sweet setup with your AC200p too! Your videos are very good on the topic, thanks for sharing.
@@Jasonoid thanks man, I appreciate you watching them.
@@Jasonoid this is the guy the encouraged me to install my transfer switch for my ac200p last winter. I'm about to get a B300 soon to hook the ac200 up to it
Is the neutrals bonded with the house when you have the power station connected?
My neutral bar and ground bar are separate in my power box. Mine is an older home so not sure what a new one looks like.
Does this setup run your furnace? How many watts does your furnace draw?
Yes, it will fun my furnace. My furnace pulls around 500 - 650 watts while running. Each model will be a little different.
Jason, I have almost an identical setup with a Bluetti going to a transfer switch. I purchased some solar panels for the bluetti, but I'm wondering what else I need between the panels and the Bluetti in order to get it permitted. I'm thinking it would require fuses and a quick disconnect. Do you have any thoughts or info on this?
Permits are different for each location. I'd definitely recommend a properly rated DC circuit breaker for the main solar line. That might also count as a 'quick disconnect' switch, you might need both.
Solar panels in series don't require fuses since the voltage is added up and the amperage stays within the panel max tolerance. If you are connecting panels in parallel, you'll need fuses.
Hi Jason, great video. Also would it not be a wise investment to go with Signature Solar 48 volt split phase all in one unit with a 5kWh server rack battery for a total of around $2700 instead of $3600 for the Bluetti ? The Signature Solar system would offer more options and capability than the Bluetti. I do not work for Signature Solar or have any vested interest in that company. I am only pointing this out from a value per dollar for the consumer and as a better/cheaper way to power your home. Also if you want portability you could mount that equipment on a roller cart as I know the Bluetti is portable somewhat.Let me know your thoughts. Thanks for a great channel.
That would be an EXCELLENT way to go if someone was comfortable putting together the system. A DIY build can really save on costs. I recently built a 24v system using and 'All in one' inverter like that ( ua-cam.com/video/Ksnv9IewYAY/v-deo.html ). It does take some knowledge and background to build a system like that and it just depends what someone is comfortable doing. I like both DIY and 'off the shelf' options and I try to cover both on my channel.
@@Jasonoid Thanks for your reply, I actually saw that video some time ago. You are correct Jason, it is simple but would take some effort to implement. On another subject do you want to share if your background is in EE or how did you come to be interested in solar,electrical, power systems etc? Maybe just a hobby?
I'm not an EE, it's just a hobby. I usually talk about that type of thing during my livestreams. I'll have one this weekend.
How can I install the transfer switch inside, where my power station is while my main breaker box is outside?
You'll have to run wires inside but it's a doable thing. That's a job for an electrican for sure 👍
What is the cable you are using for the AC300 to the manual switch ? My manual switch have 4 prongs yet the BLUETTI is only 3 prong?
Links to everything I purchased are in the video description. The 4 prong to 3 prong adapter cable came with my transfer switch.
So if you place the ttansfer switch to generator does it trip your main breaker?
It bypasses the main panel when in use, so you are usually using the transfer switch or the main panel, not both at the same time.
exactly what I'd looking for. Thanks
Glad I could help!
This is great but what I really want is a transfer switch that will flip circuits over to power station automatically when the grid power fails. Does such a unit exist?
They do have automatic transfer switches, I think they cost a bit more.
@@Jasonoid I haven't seen one available that isn't proprietary/ designed to work with a particular brand of automatic generator, or is intended for use in an RV. My concern with the latter is they are not approved for residential use / to code...
@@garethw001 I've seen a bunch from Generac but I've never read into if they are only compatible with their gas generators. With time we will see more options for power stations / batteries. If you go with an All in One setup like an EG4 or a Growatt unit they have built in automatic transfer switches I believe.
Thanks you made it so simple.
Thanks Marva!
Great Info. Thank you!
Looks like a nice canned food storage shelf. In the video when you switched to basement to shore power the lights actually got brighter. Was that real or a play with the camera white balance due to the flicker?
Probably the camera playing games, the voltage output is the same on the inverter as wall power and I never noticed a difference in real life. You can see the canned storage build video here:
ua-cam.com/video/hSZ0Hh3urvM/v-deo.html
What I don’t get is the max current into that transfer switch is 30 amps. But there are 6 circuits at 15 or 20 amps each.
Is there any chance you could max out the current when all 6 circuits are running?
You have to be watchful and manage your loads in your house or you'll overload the power station inverter and it will shut off. For example, running a toaster, a full size microwave, and coffee maker would be too much for the inverter. You could only run one or two devices at a time.
This is exactly what we need Thank You 😎👍🏼
I was hoping this would be helpful for my viewers, I'm excited to see how it works!
Just installed this same setup with 6 circuit transfer switch. However, it has started tripping GFCI breakers. I'm guessing this is because the AC300 is bonded internally? Have you had this issue as well?
That could be the case. I only charge with solar input and never have it tied into the wall for wall charging or UPS mode.
