Hi Brian, I came back to view this comprehensive review once again in order to better understand the features of my Aims global LF inverter. After living on an extension cord for many years I now understand I should set those dip switches to battery priority to avoid popping my 15a breaker so much. In effect I will have 20 amps available current. Thanks so much for making this video as I can now run my microwave and A/C simultaneously. What a game changer. Thanks again.
This puppy is identical to my Aims Global AF inverter yet with a different case however... yours has a much more powerful charger (mine is but 30A). Very reliable and carefree inverter to own. Be aware that when the 0-9 rotary charger dial is set to 100% the charger it can easily trip a typical 15A household breaker. Its best to dial it down or install a 20A outlet and breaker. Thanks for thegreat video and for all that you do for the off-grid community.
Hi Brian. We have watched this video several times during the installation of our battery bank and inverter charger. Thank you very much for producing such high quality and informative videos!!!
Tito, your videos helped me select the Sun Gold Power 3000Watt Inverter/Charger for my Class B Camper Van. The electrical system in my van is powered by a 520aH LiFePO4 battery bank. The main consumers are a microwave, TV, laptop, and an 8000BTU air conditioner. My choice of the Sun Gold Power was based on the charging output, and the capacity of the pure sine wave inverter to support my devices while boondocking -(OK - Camping Off-Grid), and the price. It has all the attributes of some of the more expensive units available. When I received the unit, I was very pleased at the quality of construction, and care taken in packaging it. The installation was easy, and the instructions provided were top-notch. Even though I have 30+ years of building and using similar systems, good instructions are very useful. Now, they include a 2 year warranty, matching what appears to be the industry standard. The unit is excellent value for money, and the technical support after the sale - Outstanding. I highly recommend the product, the company - Sun Gold Power, and their support team! Unfortunately after several trips in my camper/van, the inverter stopped. The charger continued to function 100%. I immediately contacted the company and they assigned me a personal representative. Together we got "right-on-it." Their email assistance provided several simple checks to help determine and isolate the problem. Opening the inverter was easy and the unit appeared to be well laid out and solidly constructed. A real plus in my opinion. The guidance was helpful and clear. The problem proved to be the mainpower supply board. They sent one out from a US-based warehouse, and delivery was within a few days. Again, they provided helpful support for the removal and installation of the board and a set of test procedures, to check all was well before I reinstalled in my rig. Within a little time, I had the system repaired and reinstalled in my van. Everything is functioning 100%. I highly recommend the 3000Watt inverter/charger! Their support after the sale to resolve my issues was second to none. Thanks for the comprehensive video - it help me make a great choice.
Great update. Thanks so much for circling back to share your experience! That's great to hear that the support team helped to get you back up and running quickly.
Brian - as usual, another awesome video. It's especially relevant because I was just starting to look into doing something like this. Thanks for the unintended help with my research!!!
i agree he dose a good job but he missed one of the most important things idle currant i think it may be really big on this one and many others low frq the kind this one is is also very important low frq are the heavy ones with the big transformer the square looking transformers are the cheaper transformer type the round looking transformers are alot more expensive they contain the magnetic flux much better so they waste alot less power if your idle current is 2 amps and your voltage is 54 volts normal for a 48 volt battery bank amps x volts = watts so 2 amps x 54 volts = 108 watts now 24 hours in a day 108 watts x 24 =2592 wasted watts every day 365 days =946,080 you have two buy extra batterys extra solar panels extra charge controllers extra wire fuses circuit breakers extra cost to install and extra things i likely left out that is a simplified estimate for watt hour there are other factors but lower idle is very important the wasted can be bigger than the usage on some small systems there could things we keep plugged in when not in use can add up to more wasted than used even easier to over look if a person would take the time to see what they waste along with see what the least they can use comfortably it may just be way less than half the price without compromising comfort in a lot of cases it is cheaper to buy a new higher seer rated heat pump or better yet a few new mini split heat pumps even if there heating cooling unit is as new as 4 years old same goes for fridge and other appliances i would not buy a high frq inverter they do not do as well at starting loads and blow up no matter the name brand there is some cases that a high frq will do as good as a low but they still have alot more parts the more part the more likely for failure with inverters just because you pay more for big name dont mean it will not blow up 1 day after warranty runs out this happens every day countless storys on line about this i did build my own low frq inverters for this very reason for myself family and friends now i use gentry solar inverters and recommend them to family and friends they was a new inverter company that i have followed or they may say dive insane for a few years now they are the best on the market dont cut corners to make or save more money sid designed and wrote the programing he is a godly good man and has live totally off grid for many years he made the very best possible inverter at affordable price i bugged sid and sean the owners to death until they let me beat the life out of there 6k GS inverter in the testing phase i honestly would put there 6k gs up against any other 6k inverter made they have a digital display they have wi fi so you can see and change setting from phone along with all the bells and whistles high dollar high speed fans that change there speed as needed and i have seen there 6k inverter run 8k continuously with the safty setting turned off the fans are fast and a little loud when ran full out but high speed fans makes sure it never runs hot running hot greatly shortens the life of inverters when buying any name inverter its out put power should be the highest possible load you would ever pull not the your every day loads this means the fans will very rarely or never run full speed if you sized it correctly they know people either dont know or dont care so they built it with that in mind i am not part of or benefit in any way from this company just really impressed i think there 6k low frequency pure sine inverter in around a thousand bucks almost forgot it has a very low idle current and has a big heavy round type toroid transformer it is also stainless steel case so yes sid thought of every thing if you at least consider what i wrote above no matter the inverter you buy you shouldnt waste lots of money or get burnt to bad it is really easy to do hope my book of a post helps you some if you want to give building your own a try thebackshed.com for help doing so thats what i did i have a few of my builds on there with pics and every step my user name is benandamber on thebackshed form i didnt know much about inverters when i desided to build my first one and it steal works great God bless you and yours
Some people can play musical instruments without reading sheet music........it seems that electricity is your instrument. I enjoy your videos, but sometimes I don't fully understand them....but still enjoy watching. (I like listening to music too, but can't play a note) Thumbs up!!
I just ordered mine. I watched your video about using a transfer switch and a relay with an inverter to run all of the outlets off the inverter. I have a travel trailer so I had do a different location for my setup. I upgraded to 4 100 amp hour Battle Born batteries this year. My goal was to test how long I could run my 8000 BTU ac unit( 550-600 watts) and my 900 watt micro wave( it draws about 1500 watts). I have a 3500 running/9000 surge watt pure sine wave inverter with a wired remote start panel. It worked great with my ac. I estimated at least 7 hours runtime without any additional power ( solar,etc) . The micro wave however, would not run more than a minute without the inverter shutting off. It was drawing about 1500 watts and the battery voltage was about 13 volts( well within inverter running specs) After my last test, the inverter overloaded and will not reset.So, I said "Enough" and will try this inverter charger. Wish me luck LOL
When you get it, make sure you set the dip switch setting for low-battery shutoff to 10.0V instead of 10.5V. That will keep it from shutting down so quickly.
Hey Brian, Great review of the Sun Gold 3000-0Watt inverter/charger. Best I've seen. Kudos and much thanks. I was wondering how one wires a genset and grid power on the AC side of the inverter. There's only one set of connectors for the AC in and one for the AC out.
You're correct. There is only one AC input. It is not intended for both grid and generator inputs. Let's assume your AC input is a gas generator with an auto start feature. The dry contacts will activated when the DC voltage drops below the low voltage level. The end result would be your generator starting up. The inverter would pass through that power to the loads while recharging your battery. I was actually using this inverter today to test a new battery. It's still a very solid unit.
Hi Brian, Once again, a really great and informative video. I enjoy every one of them, although I do miss the earlier ones where your intro included your guitar and the content was trip based. I'll bet that, given this little taste, you'll get the bug for a whole house backup system soon. I've used a Xantrex 24-Volt, 4-KW inverter/charger here in Kingston for about ten years and plan to never go back to PSE power outages. The internal transfer switch in the Xantrex is so fast, I often never realize the power has gone out. None of the computers ever reset and the TV and Internet router just keep going. Comcast is backed up for around eight hours. If the outage goes longer, a 16-KW generator picks up the extra as well as running the water heater, the heat strips in the furnace and the clothes dryer. If you do get the bug, 3-KW might do it depending on what you like to run during outages. I'd suggest the addition of a Xantrex (or equivalent) transformer which will produce the opposite phase for a whole house, split-phase wiring solution. Almost all houses built in the last fifty years are split-phase. This split phase will produce 240 Volts, but I don't run the very large, 240V loads from the inverter/batteries as they would run down my batteries too quickly. As it is, the system will power my typical household loads for about four hours on 2400 Watt-hours of lithium batteries. My inverter also has programmable relays for starting a generator and I've designed the circuit for this but haven't had the ambition to tear open the Kohler and make the modifications so I still go outside and just push the button if the batteries ever get down around 10%. Best regards
That's a pretty nice setup. Thanks. Yeah. We still have a many UPS units for the internet and network plus a large generator that can run off propane (which is how I prefer to run it). But it seems to be overkill most of the time.
I'm having a problem, when plugged into AC power, the battery charger is not keeping the battery charged. The system is installed in a RV, everything is 12 volts but the microwave and two outlets with small fans. For some reason the unit is very warm, even when the unit is not charging. Can you go over the DIP switches better. Your video is the best one I found on the web.
Hi Brian! Very interesting and informative video! It must be a great feeling to have companies send you high dollar freebies! 😂. For a 3000 watt inverter that sells for a fraction over $700 that’s a steal imo!…especially for all that it does for that low price! Thanks for sharing! Stay safe! ~Jim~
@@RVwithTito Agreed. If it would work on a residential fridge I would be very surprised the fridge would ever be able to enter a defrost cycle as it would have to have uninterrupted powered for several hours before it decides on that. I believe there are also many devices that could die from the repeated shock of that pulsating cycle. That makes this "power saving" functionality a bad sellers gimmick :-( I love the review though and yes you felt that right, people like me love to see a quick shot of the inner sides of devices, the size of the low frequency transformer, the size of the wires and even the number of power fets and diodes. It keeps on surprising me that manufacturers expect us to fat 4/0 wire while they themselves run like 6 gauge wire inside :-)
i just bought a power jack 10kw inverter with TWO MASSIVE TOROIDS it can def handle at LEAST 8kw continuous but its not split phase apparently you can buy a board to make it split phase got it for 250 and it works great pure sine wave lf. Oh and a 200amp battery charger built in
just hooked mine to 120 and batteries. the battery side functions fine but ac side won't power up, thought maybe it needed the earth ground lug hooked up but see that yours is working without being hooked up, yes i tried all modes multiple times. and confirmed 120 at the terminals
Perhaps I missed it, but can this model inverter trigger a generator to start automatically if the battery voltage drops to a pre-set low limit? Great video- thanks!
A free inverter is hard to pass up, and you know about the Multiplus, but they now have the "II" model with full 50 a pass through. Nice explanation and it does look pretty good for the price. Especially considering charger and ATS built in.
Thank you for the information. You are one of the few that explains it so well. I'm a Master electrician for 47 years good job keep up the good work. So I install a multi plus 2 inverter like you have at your shop I install it Horizontal instead of vertical battle born batteries in Reno where we lived said that it's OK to go horizontal also what do you think. Keep up the good work See you on the road.
Thanks! If you can get good airflow through it then it should be ok. Yeah that multi plus is going in the RV soon and it will barely fit vertically. The mounting bracket is designed for a vertical hang but all the connections are in the bottom. My 4/0 cables will be tight. I'll put some cooling fans above it to pull hot air out.
Good video. Did you have a T-Fuse and battery disconnect on the positive DC side? One thing you need to always test is, if there is any voltage on the AC between the ground and neutral sockets? Anything over 3 volts AC and I would reject the unit as unsafe.
I have this same unit in my camper. It's hooked up to a Renogy deep cycle AGM 12 v 200 Ah battery. When the battery is fully charged the inverter will shut down in only 30 minutes if I run a small 1500 watt portable heater at medium setting. Am I expecting to much or is there something wrong with my unit?
@10:24 Regarding Automatic Generator Start (AGS), have you tried that? I have had difficulty getting the SunGoldPower 3000W inverter AGS to start or stop my 2020 Onan 2500 LP generator using the inverter's AGS dry contacts. For those unfamiliar, dry contacts are a safe and standard interface for many worldwide generators that provide the automatic remote start function when the battery voltage gets low (10/10.5V). Can you kindly demonstrate the AGS on this inverter?
I also want to point out this inverter has a surge protection setup and will take battery power to stabilize the output voltage if shore voltage droops to compensate this is likely where your getting that delay issue unhook grid power completely and redo your tests the hybrid function of these are amazing and I did some research these are literally identical to my aims inverter AIMs allowed the company to copy theyre design for a royalty fee there are a few companies doing this with AIMs's design.
This is very well done. Thank you for putting this together. So what would happen if you were charging your batteries on solar and the battery charge level dropped below the threshold, and the AC kicked in and started charging the batteries also? Is there a possibility that the two sources could overcharge and damage the battery?
I am looking to diy a similar setup. lots of good reviews on the on the low frequency inverters like these. but the downside is it take upto 100 watts on standby mode . did you happen to measure it?
Let's see. Feels like a math story problem :) I just measured the 3 second pulses. It pulls about 0.2A per pulse. That's about 20 seconds per minute at 4A per minute (0.2A * 20). So 48W per minute (4A * 12V). You may want to check my math since it is Saturday night :) I supposed it's much less than the 3A continuous draw (with no AC load) when not on power saver. Hope that helps.
Acc. To the specification it draws less than 25W in power save mode. I think 25W (2A) is to much for an RV. 0.5-1 A would be acceptable. Please include this in your next test.
I have this Sun Gold Power (4000w) inverter at an off-grid seasonal cabin. It is turned off when I am not there. It’s under two years old and has worked fine since it was installed. It recently started to turn itself off after being on for about 15 seconds. Upon turning it to the off position and restarting it, it again continues to shut itself off within a minute. The LED readout is scrambled and unrecognizable. Any thought on what is causing this to occur?
Hi. Very good explanation and test of the inverter. I still hadn't found someone capable of explaining it like you. I have a question regarding the WS4 mode that you were explaining. I understood that the batteries are discharged to the minimum of the indicated, it begins to charge the battery, using the energy of the grid tie. All I asked is, when the batteries are finished charging, the inverter returns to its normal state, using the batteries?
I have a question I have 3000 watt sungold power inverter charger looks the same I use it for off grid recently my generator governor spring broke replaced it now I having alot of problems with charging my batterys I turned down volts to 117 and inverter charger clicks on and off short cycles what can you make of this mess
I have a 4000w Sungold it won’t go back to save mode after it’s activated :-(. And it takes a pretty good load to activate :-(. Can’t use it in my off grid setup :-(. Other than that it seems to work pretty well.
Thanks for the review. Do you know if it has something similar to the victron powerassist function (ie combine AC with battery where AC or battery alone might not be enough - eg for RV AC? If not, are you aware of any inverter/charger that does besides victron?
I just found your video, and inflation is in full swing, it’s $825 now, lol. Still it looks like a nice unit. I tried a Renogy 3,000 watt because of the price, it was dead out of the box. Returning it under 30 day policy. QUESTION; Can you use as a stand alone inverter for now, then use the charge function later? I’m looking to put an inverter in my camper that’s separate from the main system. Set it up with a 30 amp plug, if no shore power, plug it in. The rv will be fully functional limited by battery bank and solar. Thanks
Thank you for the video. I bought this inverter and three batteries before we left and didn't have a chance to install it. I need to figure out how to get it hooked up to shore power as well as our generator. Any suggestions? Thanks
Option one would be to get an automatic transfer switch (amzn.to/3kcuG0x). Your shore and generator connections go in, and one connection comes out. It's switched automatically. The second (easier) option is to add female 30A plug to your generator output. To use your generator connect the generator output to the shore power cord. Hope those helps.
Wiring this into a sub panel that goes to the main panel that is earth grounded, would this cause an issue seeing it appears the inverter has a bonded neutral.
I've had this inverter installed in my RV for a year now and very happy with it. Hooked up to 2 280ah batteries in parallel. I kinda wish I had the display on the remote like the aims does but otherwise it's been great.
Check the manual on the absorption time. Sigineer and Aims units have very long absorption times that is not good for LFP. if you're manually terminating charging or you have it set for the LFP 13.8V charge/float, then no biggie.
Which one would do you think would be better for RV applications....Victron Energy MultiPlus or this sungoldpower ? Looking to upgrade from a Victron 1200 inverter....
It's hard to beat the modular network and communication capabilities of a Victron system. Of course, it's a more expensive setup. This SunGoldPower inverter seems solid though as a low-cost alternative. In case you're wondering, I use all Victron gear in my Class A including a Multiplus II. You can download my system diagram at RVwithTito.com/downloads
@@RVwithTito Thanks you so much for your reply.... I've been following you for a while now....you really put out some of the best content !....all my equipment is Victron now but hard to justify $1500 to my lovely wife...lol....we spent 3 months on the road last year and our system was adequate but its addictive and I want more power... Haha...Hope to see you on the road !
Hi I just installed a 4000 Watt sun gold inverter/charger In have 120 bolts input but nothing is happening, no fans or lights , would you have any suggestions as to why Thanks Joe
The generator should work the same as if you're plugged into shore power. Just plug your generator into the shore power cord and the pass-through feature of this inverter should power your rig and charge your batteries.
Hello. What would be your recommendation for someone that has an on board generator but would like to be able to run AC power for televisions and charging devices only without powering up the generator? Can this (or some other unit) be configured just for AC outlets? I’ve been looking at the multiplus 2 but the whole set up is pricey just to watch tv and charge devices only. Thanks
@@housesOTR Lots of options there. I have a Samlex 2K PSW in my class C. Works good. Xantrex is good too. Try and find one that comes with a remote. I've heard many complaints about the Renogy ones though.
Having big problems with the charging section of this inverter. The LifePo4 charging option only charges to 13.7volts. Sungolds own documentation states that the lithium charging profile only charges to 14.0 volts. All manufacturers of LifePo4 batteries and chargers use a range of 14.2~14.6 volts. Am I the only one that sees the problem with this?
This inverter looks great but what worries me is that it looks a copy of AIMS inverter, i have a 3000 watts AIMS inverter and looks almost exactly to this one.My AIMS inverter fails after "two years" of very soft use (use only when power outage). Basically in my home i have small electric appliances like 700 watts coffee maker, 800 watts microwave oven a brand new refrigerator that consumes very low wattage all the rest are leds light and few electronics ,nothing of air conditioner.
I recently purchased this. I am using this with my new 1,470 AH lead acid battery bank. It never goes into float mode even though the green float LED is on. It will charge the bank to 14.8V @ 50A, then taper current to 0A. As soon as the bank reaches 13.3V, the process is repeated again and again. My battery's boil! This inverter does NOT have a true float mode! Not happy! I had to purchase a separate float charger.
Thanks for the video. Would this work to replace a 1000w magnum converter to run my whole 30 amp Winnebago. I have a 260 ah lithium battery and want to run my a/c and my convection oven for short periods of time.
I have the Aims version of this running my Class C. I have 400ah batteries with 800 watts of solar. This inverter-charger is a great asset. It allows me to go completely free of shore power. It runs the entire coach, just as if I were plugged into shore power or had the genny running.
I cannot get my 3000w 12v sungoldpower inverter to fully charge my single 300ah LiFePo4 battery. At 43% the "fast" charge switches to "float" charge and ceases charging the battery. The battery reads 13.7v and appears to force the charger to float even though its only at 43%. I have left it in float mode for 10 hours and the battery does not charge anymore at all. any thoughts.
I need a system (or want) a system that would use the battery priority but if I turn on a hot plate or some things with high draws such as electric hot plate and instapot and/or water heater (what is a hot water heater?) or boil pot, ... I'd like to temporarily run it off show so as battery is not charged too low... I want to see if solar is connected too I'd rater the solar charge than shore power. So mostly wanting to run battery (12V loads) and keep charging it solar and auto switch to shore (you said batt priority mode (I don't think Victron does this)) ... and then a more feature to use shore with hot plates etc. I think I'll have to find a way to manually do it... also power saver is nice... If solar charges, I wonder which would prioritize or maybe both charge at the same time.
Did you ever come up with a solution to your question above? on my current camper I installed a transfer switch that allowed me to do that ... BUT on the new to me camper I am purchasing I want to put a new solar array and power inverter in .. and I would like to do the same. BUT a little more simplistic. Was hoping this would do the trick.
Yes...sort of. Typically your battery charger, batteries and 12V system will all be connected either directly or indirectly. So depending on your battery state of charge your charger and batteries may both power your 12V DC loads. The flow of energy will always be from the higher voltage source to the load.
I've been looking at this inverter. Can you run the inverter and turn on an AM Radio either battery powered or plug in and listen for any RFI (Radio Frequency Interference) static. Being a low frequency inverter I would be interested in how it performed under a load.
Will this switch from the home AC to batteries before it fails? meaning if there are not enough Amps available on the homes circuit due to other loads on the circuit?
If solar is involved.. would you simply hook up the solar charge controller on the battery terminal and charging can come either from inverter/charger and solar charger? Any issues there?
I have this exact inverter but I am having trouble with the shore power charging function. Does anyone know why that might be? It had initially started to charge but at some point shut down and will not start again. I have cut power, changed to a higher gauge cord to plug in shore power, and checked all connections. It is functioning on shore power mode and showing everything coming in properly. It just won't switch to charge mode.
You might want to check into that for 3000w you need 4/0 wire for anything over a 3foot run of wire 2/0 for under 3ft this is nearly exact same inverter as the the aims inverter I have and at 3000w load your talking over 300amp draw 1/0 will not carry that and the inverter will get massive voltage droop causing even more amp draw and heat / strain on the inverter.
Yeah. That probably won't take it to 100% SOC but close. I've been trying some of the other profiles with these LiFePO4s 14.0-14.6. I like the AGM profile the best with the 14.1 bulk and 13.4 float.
I have 100 AH 12 volt Battle Born Batteries.. I talked to their support guy and he said to use the seal lead acid setting. BB batteries need at least 14.2 volts to top balance.
Seems odd that they would have a lipo4 setting, however, you need to set it differently to charge lipo4. Sure, another profile would work, but it is a confidence breaker
Everyone comments that it is similar to an Aims. The Aims I have is 2000 watt with the transfer switch. If I connect it to a protected outlet, GFCI, it trips the protection of the outlet. My inverter generator has a protected outlet. Anyone know if this inverter does the same thing?
Ok I watched your video twice and did some research. SunGoldPower headquarter in China and will explain the less cost, currently going to $735 and offering free shipping and no tax until 31 Oct. My only concern, if you need tech support, then you need to wait until after 8 PM to contact someone on the east coast? I worked for Tech Support for IBM and my counterpart in China didn't start until 8PM, and I needed to start at 4 AM at the end of shift. I am concern about getting stuff from China. With the Supply Chain issue we are having now, if you order one how some will it here. My biggest concern is tech support for setup and will they be about to understand me.
Hi Brian, I came back to view this comprehensive review once again in order to better understand the features of my Aims global LF inverter. After living on an extension cord for many years I now understand I should set those dip switches to battery priority to avoid popping my 15a breaker so much. In effect I will have 20 amps available current. Thanks so much for making this video as I can now run my microwave and A/C simultaneously. What a game changer. Thanks again.
This puppy is identical to my Aims Global AF inverter yet with a different case however... yours has a much more powerful charger (mine is but 30A). Very reliable and carefree inverter to own. Be aware that when the 0-9 rotary charger dial is set to 100% the charger it can easily trip a typical 15A household breaker. Its best to dial it down or install a 20A outlet and breaker. Thanks for thegreat video and for all that you do for the off-grid community.
I've been keeping the charger at 30A. Funny how it looks identical to the Aims ;)
SoI have two favorite Tito's, one teaches me about solar power, the other gets me in trouble!
You have some of the best tutorials on these inverters. No one else explains them like you do.
Glad you like them!
Hi Brian. We have watched this video several times during the installation of our battery bank and inverter charger. Thank you very much for producing such high quality and informative videos!!!
No problem. Glad to help ☺️
Tito, your videos helped me select the Sun Gold Power 3000Watt Inverter/Charger for my Class B Camper Van. The electrical system in my van is powered by a 520aH LiFePO4 battery bank. The main consumers are a microwave, TV, laptop, and an 8000BTU air conditioner. My choice of the Sun Gold Power was based on the charging output, and the capacity of the pure sine wave inverter to support my devices while boondocking -(OK - Camping Off-Grid), and the price. It has all the attributes of some of the more expensive units available. When I received the unit, I was very pleased at the quality of construction, and care taken in packaging it. The installation was easy, and the instructions provided were top-notch. Even though I have 30+ years of building and using similar systems, good instructions are very useful. Now, they include a 2 year warranty, matching what appears to be the industry standard. The unit is excellent value for money, and the technical support after the sale - Outstanding. I highly recommend the product, the company - Sun Gold Power, and their support team!
Unfortunately after several trips in my camper/van, the inverter stopped. The charger continued to function 100%. I immediately contacted the company and they assigned me a personal representative. Together we got "right-on-it." Their email assistance provided several simple checks to help determine and isolate the problem.
Opening the inverter was easy and the unit appeared to be well laid out and solidly constructed. A real plus in my opinion. The guidance was helpful and clear. The problem proved to be the mainpower supply board. They sent one out from a US-based warehouse, and delivery was within a few days. Again, they provided helpful support for the removal and installation of the board and a set of test procedures, to check all was well before I reinstalled in my rig.
Within a little time, I had the system repaired and reinstalled in my van. Everything is functioning 100%. I highly recommend the 3000Watt inverter/charger! Their support after the sale to resolve my issues was second to none. Thanks for the comprehensive video - it help me make a great choice.
Great update. Thanks so much for circling back to share your experience! That's great to hear that the support team helped to get you back up and running quickly.
Brian - as usual, another awesome video. It's especially relevant because I was just starting to look into doing something like this. Thanks for the unintended help with my research!!!
Glad it was helpful!
i agree he dose a good job but he missed one of the most important things
idle currant i think it may be really big on this one and many others
low frq the kind this one is is also very important low frq are the heavy ones with the big transformer
the square looking transformers are the cheaper transformer type
the round looking transformers are alot more expensive they contain the magnetic flux much better so they waste alot less power
if your idle current is 2 amps and your voltage is 54 volts normal for a 48 volt battery bank
amps x volts = watts so 2 amps x 54 volts = 108 watts now 24 hours in a day 108 watts x 24 =2592 wasted watts every day
365 days =946,080 you have two buy extra batterys extra solar panels extra charge controllers
extra wire fuses circuit breakers extra cost to install and extra things i likely left out
that is a simplified estimate for watt hour there are other factors but lower idle is very important the wasted can be bigger than the usage on some small systems
there could
things we keep plugged in when not in use can add up to more wasted than used even easier to over look
if a person would take the time to see what they waste along with see what the least they can use comfortably
it may just be way less than half the price without compromising comfort
in a lot of cases it is cheaper to buy a new higher seer rated heat pump or better yet a few new mini split heat pumps
even if there heating cooling unit is as new as 4 years old
same goes for fridge and other appliances
i would not buy a high frq inverter they do not do as well at starting loads and blow up no matter the name brand
there is some cases that a high frq will do as good as a low but they still have alot more parts the more part the more likely for failure
with inverters just because you pay more for big name dont mean it will not blow up 1 day after warranty runs out
this happens every day countless storys on line about this
i did build my own low frq inverters for this very reason for myself family and friends
now i use gentry solar inverters and recommend them to family and friends
they was a new inverter company that i have followed or they may say dive insane for a few years now
they are the best on the market dont cut corners to make or save more money sid designed and wrote the programing
he is a godly good man and has live totally off grid for many years he made the very best possible inverter at affordable price
i bugged sid and sean the owners to death until they let me beat the life out of there 6k GS inverter in the testing phase
i honestly would put there 6k gs up against any other 6k inverter made
they have a digital display they have wi fi so you can see and change setting from phone along with all the bells and whistles
high dollar high speed fans that change there speed as needed and i have seen there 6k inverter run 8k continuously with the safty setting turned off
the fans are fast and a little loud when ran full out but high speed fans makes sure it never runs hot
running hot greatly shortens the life of inverters
when buying any name inverter its out put power should be the highest possible load you would ever pull
not the your every day loads
this means the fans will very rarely or never run full speed if you sized it correctly
they know people either dont know or dont care so they built it with that in mind
i am not part of or benefit in any way from this company just really impressed
i think there 6k low frequency pure sine inverter in around a thousand bucks
almost forgot it has a very low idle current and has a big heavy round type toroid transformer
it is also stainless steel case so yes sid thought of every thing
if you at least consider what i wrote above no matter the inverter you buy
you shouldnt waste lots of money or get burnt to bad
it is really easy to do hope my book of a post helps you some
if you want to give building your own a try thebackshed.com for help doing so thats what i did
i have a few of my builds on there with pics and every step
my user name is benandamber on thebackshed form
i didnt know much about inverters when i desided to build my first one and it steal works great
God bless you and yours
Fascinating review. Even a year after the fact. I’m gonna learn all this stuff yet!
Thanks! Glad it helped.
It's all ways good have back up power never know when power go out nice video cool
Some people can play musical instruments without reading sheet music........it seems that electricity is your instrument. I enjoy your videos, but sometimes I don't fully understand them....but still enjoy watching. (I like listening to music too, but can't play a note) Thumbs up!!
Thanks for singing along :) There's always something new to learn and my curiosity keeps my brain very active.
I just ordered mine. I watched your video about using a transfer switch and a relay with an inverter to run all of the outlets off the inverter. I have a travel trailer so I had do a different location for my setup. I upgraded to 4 100 amp hour Battle Born batteries this year. My goal was to test how long I could run my 8000 BTU ac unit( 550-600 watts) and my 900 watt micro wave( it draws about 1500 watts). I have a 3500 running/9000 surge watt pure sine wave inverter with a wired remote start panel. It worked great with my ac. I estimated at least 7 hours runtime without any additional power ( solar,etc) . The micro wave however, would not run more than a minute without the inverter shutting off. It was drawing about 1500 watts and the battery voltage was about 13 volts( well within inverter running specs) After my last test, the inverter overloaded and will not reset.So, I said "Enough" and will try this inverter charger. Wish me luck LOL
When you get it, make sure you set the dip switch setting for low-battery shutoff to 10.0V instead of 10.5V. That will keep it from shutting down so quickly.
@@RVwithTito noted, thanks
@@RVwithTitowhats idle consumption again? It can be a deal breaker.
Excellent video, thanks for the great demo
You're welcome!
Hey Brian, Great review of the Sun Gold 3000-0Watt inverter/charger. Best I've seen. Kudos and much thanks. I was wondering how one wires a genset and grid power on the AC side of the inverter. There's only one set of connectors for the AC in and one for the AC out.
You're correct. There is only one AC input. It is not intended for both grid and generator inputs. Let's assume your AC input is a gas generator with an auto start feature. The dry contacts will activated when the DC voltage drops below the low voltage level. The end result would be your generator starting up. The inverter would pass through that power to the loads while recharging your battery. I was actually using this inverter today to test a new battery. It's still a very solid unit.
Hi Brian, Once again, a really great and informative video. I enjoy every one of them, although I do miss the earlier ones where your intro included your guitar and the content was trip based.
I'll bet that, given this little taste, you'll get the bug for a whole house backup system soon. I've used a Xantrex 24-Volt, 4-KW inverter/charger here in Kingston for about ten years and plan to never go back to PSE power outages. The internal transfer switch in the Xantrex is so fast, I often never realize the power has gone out. None of the computers ever reset and the TV and Internet router just keep going. Comcast is backed up for around eight hours. If the outage goes longer, a 16-KW generator picks up the extra as well as running the water heater, the heat strips in the furnace and the clothes dryer.
If you do get the bug, 3-KW might do it depending on what you like to run during outages. I'd suggest the addition of a Xantrex (or equivalent) transformer which will produce the opposite phase for a whole house, split-phase wiring solution. Almost all houses built in the last fifty years are split-phase. This split phase will produce 240 Volts, but I don't run the very large, 240V loads from the inverter/batteries as they would run down my batteries too quickly.
As it is, the system will power my typical household loads for about four hours on 2400 Watt-hours of lithium batteries.
My inverter also has programmable relays for starting a generator and I've designed the circuit for this but haven't had the ambition to tear open the Kohler and make the modifications so I still go outside and just push the button if the batteries ever get down around 10%.
Best regards
That's a pretty nice setup. Thanks. Yeah. We still have a many UPS units for the internet and network plus a large generator that can run off propane (which is how I prefer to run it). But it seems to be overkill most of the time.
I'm having a problem, when plugged into AC power, the battery charger is not keeping the battery charged. The system is installed in a RV, everything is 12 volts but the microwave and two outlets with small fans. For some reason the unit is very warm, even when the unit is not charging. Can you go over the DIP switches better.
Your video is the best one I found on the web.
An excellent review, Brian. Based on your testing I will definitely consider buying it if I have a need for an inverter in my workshop.
Thanks. Looking forward to installing a sub-panel to power more stuff.
Cool video,i have the 6000w 48v similar inverter to yours,it's a solid unit ,I have abused it running a welder without any issues .
I haven't had a chance to run the welder yet, but I'm sure it will work since I only run it on 110 anyway for some basic flux-core welding.
I really wanted to see that clamp meter on the battery cable when the table saw and shop-vac were both running.
Hi Brian! Very interesting and informative video! It must be a great feeling to have companies send you high dollar freebies! 😂. For a 3000 watt inverter that sells for a fraction over $700 that’s a steal imo!…especially for all that it does for that low price! Thanks for sharing! Stay safe! ~Jim~
hi Brian, good review, I read somewhere that Power Save mode not recommended for refridgerator, doesnt usually turn them on. My 2 cents. Cheers.
Yup. 1 second pulse may not be enough for lots of equipment but I can't say which. Thanks for the $0.02.
@@RVwithTito Agreed. If it would work on a residential fridge I would be very surprised the fridge would ever be able to enter a defrost cycle as it would have to have uninterrupted powered for several hours before it decides on that. I believe there are also many devices that could die from the repeated shock of that pulsating cycle. That makes this "power saving" functionality a bad sellers gimmick :-(
I love the review though and yes you felt that right, people like me love to see a quick shot of the inner sides of devices, the size of the low frequency transformer, the size of the wires and even the number of power fets and diodes. It keeps on surprising me that manufacturers expect us to fat 4/0 wire while they themselves run like 6 gauge wire inside :-)
@@cobbles62 Glad you enjoyed the review, but yeah about the power saver...seems cool, not sure when I'd use it.
Great review and explanation of its capabilities.
Thanks. I appreciate the feedback.
i just bought a power jack 10kw inverter with TWO MASSIVE TOROIDS it can def handle at LEAST 8kw continuous but its not split phase apparently you can buy a board to make it split phase got it for 250 and it works great pure sine wave lf. Oh and a 200amp battery charger built in
I was just going to say it resembles the AIMS Pure Sine 3000 that I once had. Same features.
Thanks for a great in-depth review. I have been considering this inverter.
This inverter is build by YIYEN in china. I have been off grid for 4.5 years now with there 12kw size These are good stout basic converters.
Good to know. Thanks.
I thought it was Sigineer.
@2hotscottpro Yiyen builds sigineer, Aims, some of the sungold power and many others.
Suggest when you do your load test to monitor the voltage and the AC waveform to see if there are any issues.
Will do. Thanks
just hooked mine to 120 and batteries. the battery side functions fine but ac side won't power up, thought maybe it needed the earth ground lug hooked up but see that yours is working without being hooked up, yes i tried all modes multiple times. and confirmed 120 at the terminals
Good info, thank you for your reviews and videos.
You're welcome!
Perhaps I missed it, but can this model inverter trigger a generator to start automatically if the battery voltage drops to a pre-set low limit? Great video- thanks!
Low Frequensy 🤘🏻 I'm wondering what the idle konsumption is.
A free inverter is hard to pass up, and you know about the Multiplus, but they now have the "II" model with full 50 a pass through. Nice explanation and it does look pretty good for the price. Especially considering charger and ATS built in.
Yes. I have the Multiplus II 120x2 for my 50A rig and am preparing to install it soon.
Thank you for the information. You are one of the few that explains it so well. I'm a Master electrician for 47 years good job keep up the good work. So I install a multi plus 2 inverter like you have at your shop I install it Horizontal instead of vertical battle born batteries in Reno where we lived said that it's OK to go horizontal also what do you think. Keep up the good work See you on the road.
Thanks! If you can get good airflow through it then it should be ok. Yeah that multi plus is going in the RV soon and it will barely fit vertically. The mounting bracket is designed for a vertical hang but all the connections are in the bottom. My 4/0 cables will be tight. I'll put some cooling fans above it to pull hot air out.
This is a low frequency split phase toroidal transformer inverter (the best kind :) These ones aren't cheap though.
great review!
Thank you! Cheers!
Good video. Did you have a T-Fuse and battery disconnect on the positive DC side? One thing you need to always test is, if there is any voltage on the AC between the ground and neutral sockets? Anything over 3 volts AC and I would reject the unit as unsafe.
I'll add a T-Fuse once I move it to it's permanent location. The T-Fuses I have are going in the RV. Thanks for the testing tip! Good one.
Cost as much as a growatt 3000.....😕 Great video
I'd like to have two solar panels to charge batteries when shore power is not avail. Does this unit accommodate solar panels?
I ordered that same one and wondered if I need a 2nd for my" wood shop / she shall, shed" Very new to this so any tips r welcome. Thankfully Kat
I have this same unit in my camper. It's hooked up to a Renogy deep cycle AGM 12 v 200 Ah battery. When the battery is fully charged the inverter will shut down in only 30 minutes if I run a small 1500 watt portable heater at medium setting. Am I expecting to much or is there something wrong with my unit?
I purchased one off of their website. $60 off with free shipping for a total of $675.00. It is in stock
Nice. Good deal.
How’s it been working, any issues?
@@seekingadventures No issues. Still hooked up in the shop.
@10:24 Regarding Automatic Generator Start (AGS), have you tried that? I have had difficulty getting the SunGoldPower 3000W inverter AGS to start or stop my 2020 Onan 2500 LP generator using the inverter's AGS dry contacts. For those unfamiliar, dry contacts are a safe and standard interface for many worldwide generators that provide the automatic remote start function when the battery voltage gets low (10/10.5V). Can you kindly demonstrate the AGS on this inverter?
Very similar to the PowerJack LF inverter. It is just nicer looking than the PowerJack. I found it very good.
I also want to point out this inverter has a surge protection setup and will take battery power to stabilize the output voltage if shore voltage droops to compensate this is likely where your getting that delay issue unhook grid power completely and redo your tests the hybrid function of these are amazing and I did some research these are literally identical to my aims inverter AIMs allowed the company to copy theyre design for a royalty fee there are a few companies doing this with AIMs's design.
This is very well done. Thank you for putting this together. So what would happen if you were charging your batteries on solar and the battery charge level dropped below the threshold, and the AC kicked in and started charging the batteries also? Is there a possibility that the two sources could overcharge and damage the battery?
Thanks!
I am looking to diy a similar setup. lots of good reviews on the on the low frequency inverters like these. but the downside is it take upto 100 watts on standby mode . did you happen to measure it?
Let's see. Feels like a math story problem :) I just measured the 3 second pulses. It pulls about 0.2A per pulse. That's about 20 seconds per minute at 4A per minute (0.2A * 20). So 48W per minute (4A * 12V). You may want to check my math since it is Saturday night :) I supposed it's much less than the 3A continuous draw (with no AC load) when not on power saver. Hope that helps.
Acc. To the specification it draws less than 25W in power save mode. I think 25W (2A) is to much for an RV. 0.5-1 A would be acceptable. Please include this in your next test.
So you think this unit would be great for a 5th wheel. I'm looking at the 4000w split phase 24v unit.
Hi Brian that inverter seems to have some pretty cool functions are you putting solar on your roof of the house or planning it for later 👍
Not sure yet. Maybe at some point. It would be easy to do but not necessary right now. Maybe in battery priority mode.
I have this Sun Gold Power (4000w) inverter at an off-grid seasonal cabin. It is turned off when I am not there. It’s under two years old and has worked fine since it was installed. It recently started to turn itself off after being on for about 15 seconds. Upon turning it to the off position and restarting it, it again continues to shut itself off within a minute. The LED readout is scrambled and unrecognizable. Any thought on what is causing this to occur?
Thanks
Hi. Very good explanation and test of the inverter. I still hadn't found someone capable of explaining it like you. I have a question regarding the WS4 mode that you were explaining. I understood that the batteries are discharged to the minimum of the indicated, it begins to charge the battery, using the energy of the grid tie. All I asked is, when the batteries are finished charging, the inverter returns to its normal state, using the batteries?
It resumes using battery power when the battery voltage reaches 13 volts.
I have a question I have 3000 watt sungold power inverter charger looks the same I use it for off grid recently my generator governor spring broke replaced it now I having alot of problems with charging my batterys I turned down volts to 117 and inverter charger clicks on and off short cycles what can you make of this mess
I have a 4000w Sungold it won’t go back to save mode after it’s activated :-(. And it takes a pretty good load to activate :-(. Can’t use it in my off grid setup :-(. Other than that it seems to work pretty well.
Thanks for the review. Do you know if it has something similar to the victron powerassist function (ie combine AC with battery where AC or battery alone might not be enough - eg for RV AC? If not, are you aware of any inverter/charger that does besides victron?
No it does not have a power assist like a Victron Multiplus. I love that feature on min MPII BTW. Sorry for the super late response.
I just found your video, and inflation is in full swing, it’s $825 now, lol. Still it looks like a nice unit. I tried a Renogy 3,000 watt because of the price, it was dead out of the box. Returning it under 30 day policy. QUESTION; Can you use as a stand alone inverter for now, then use the charge function later? I’m looking to put an inverter in my camper that’s separate from the main system. Set it up with a 30 amp plug, if no shore power, plug it in. The rv will be fully functional limited by battery bank and solar. Thanks
If there's no AC input then it should just function as an inverter.
As the reply mentioned, yes, if no AC input it won't charge. But, even better, you can disable the charger with a simple setting on the unit.
Thank you for the video. I bought this inverter and three batteries before we left and didn't have a chance to install it. I need to figure out how to get it hooked up to shore power as well as our generator. Any suggestions? Thanks
Option one would be to get an automatic transfer switch (amzn.to/3kcuG0x). Your shore and generator connections go in, and one connection comes out. It's switched automatically. The second (easier) option is to add female 30A plug to your generator output. To use your generator connect the generator output to the shore power cord. Hope those helps.
@@RVwithTito Thanks Tito, Doesn't the SunGold have a switch built in? I have the same model you showed.
@@tradndreams It switches between grid (shore) and inverter. With a generator you will have two grid sources.
Wiring this into a sub panel that goes to the main panel that is earth grounded, would this cause an issue seeing it appears the inverter has a bonded neutral.
It would be nice to have a working inverter bought this arrived broken they can't seem to get it fixed for me
I've had this inverter installed in my RV for a year now and very happy with it. Hooked up to 2 280ah batteries in parallel. I kinda wish I had the display on the remote like the aims does but otherwise it's been great.
Great to hear. Thanks for sharing your setup 👍
Check the manual on the absorption time. Sigineer and Aims units have very long absorption times that is not good for LFP. if you're manually terminating charging or you have it set for the LFP 13.8V charge/float, then no biggie.
@James Fisher I don't think so. I tried to do a bunch of research on it and I think I came up with the fact that I wouldn't work.
Which one would do you think would be better for RV applications....Victron Energy MultiPlus or this sungoldpower ? Looking to upgrade from a Victron 1200 inverter....
It's hard to beat the modular network and communication capabilities of a Victron system. Of course, it's a more expensive setup. This SunGoldPower inverter seems solid though as a low-cost alternative. In case you're wondering, I use all Victron gear in my Class A including a Multiplus II. You can download my system diagram at RVwithTito.com/downloads
@@RVwithTito Thanks you so much for your reply.... I've been following you for a while now....you really put out some of the best content !....all my equipment is Victron now but hard to justify $1500 to my lovely wife...lol....we spent 3 months on the road last year and our system was adequate but its addictive and I want more power... Haha...Hope to see you on the road !
Can I hook 2 together to b able to get 240v
120v from each unit
Hi I just installed a 4000 Watt sun gold inverter/charger
In have 120 bolts input but nothing is happening, no fans or lights , would you have any suggestions as to why
Thanks Joe
Great video, I have one question, I’m planning on buying a inverter generator. I can still use it with this inverter/charger right?
The generator should work the same as if you're plugged into shore power. Just plug your generator into the shore power cord and the pass-through feature of this inverter should power your rig and charge your batteries.
@@RVwithTito I guess what I wondering is if I could “over inveter” I guess if that’s a thing lol thanks for your replies
Hello. What would be your recommendation for someone that has an on board generator but would like to be able to run AC power for televisions and charging devices only without powering up the generator? Can this (or some other unit) be configured just for AC outlets? I’ve been looking at the multiplus 2 but the whole set up is pricey just to watch tv and charge devices only. Thanks
Would be nice if you had a link for a discount
I'm just looking for a plain old PSW inverter. I already have a charger. Everyone wants to add a charger, etc. Any suggestions? Love your videos!
There are several options. I've used a Progressive Dynamics charger in both RVs.
@@RVwithTito Yes, I have a PD charger already. I just need a plain old Vanilla PSW inverter. Nothing fancy.
@@housesOTR Lots of options there. I have a Samlex 2K PSW in my class C. Works good. Xantrex is good too. Try and find one that comes with a remote. I've heard many complaints about the Renogy ones though.
My battery are AGM, can it be configured to start to charge when the battery drop to 50%?
When is battery only mode
Will charge it instantly?
A 3000w 12v inverter should be running 4/0 cable for better performance
Having big problems with the charging section of this inverter. The LifePo4 charging option only charges to 13.7volts. Sungolds own documentation states that the lithium charging profile only charges to 14.0 volts. All manufacturers of LifePo4 batteries and chargers use a range of 14.2~14.6 volts. Am I the only one that sees the problem with this?
This inverter looks great but what worries me is that it looks a copy of AIMS inverter, i have a 3000 watts AIMS inverter and looks almost exactly to this one.My AIMS inverter fails after "two years" of very soft use (use only when power outage). Basically in my home i have small electric appliances like 700 watts coffee maker, 800 watts microwave oven a brand new refrigerator that consumes very low wattage all the rest are leds light and few electronics ,nothing of air conditioner.
Is a 12V unit, which if you lucky enough can pull 2000Watts before it starts giving issues to its users
Wouldn’t you install the 4000 watt unit in your RV ? Most come with 4 KW generators.
You need a huge battery bank to get 4K through an inverter.
I recently purchased this. I am using this with my new 1,470 AH lead acid battery bank. It never goes into float mode even though the green float LED is on. It will charge the bank to 14.8V @ 50A, then taper current to 0A. As soon as the bank reaches 13.3V, the process is repeated again and again. My battery's boil! This inverter does NOT have a true float mode! Not happy! I had to purchase a separate float charger.
high watt consumption during idle is the draw back
Thanks for the video. Would this work to replace a 1000w magnum converter to run my whole 30 amp Winnebago. I have a 260 ah lithium battery and want to run my a/c and my convection oven for short periods of time.
I have the Aims version of this running my Class C. I have 400ah batteries with 800 watts of solar. This inverter-charger is a great asset. It allows me to go completely free of shore power. It runs the entire coach, just as if I were plugged into shore power or had the genny running.
I cannot get my 3000w 12v sungoldpower inverter to fully charge my single 300ah LiFePo4 battery. At 43% the "fast" charge switches to "float" charge and ceases charging the battery. The battery reads 13.7v and appears to force the charger to float even though its only at 43%. I have left it in float mode for 10 hours and the battery does not charge anymore at all.
any thoughts.
Make sure the Battery Type Selector on the front is set to #7 (LiFePO4). Use a tiny screw driver to point the little arrow to 7.
I need a system (or want) a system that would use the battery priority but if I turn on a hot plate or some things with high draws such as electric hot plate and instapot and/or water heater (what is a hot water heater?) or boil pot, ... I'd like to temporarily run it off show so as battery is not charged too low... I want to see if solar is connected too I'd rater the solar charge than shore power. So mostly wanting to run battery (12V loads) and keep charging it solar and auto switch to shore (you said batt priority mode (I don't think Victron does this)) ... and then a more feature to use shore with hot plates etc. I think I'll have to find a way to manually do it... also power saver is nice... If solar charges, I wonder which would prioritize or maybe both charge at the same time.
Did you ever come up with a solution to your question above? on my current camper I installed a transfer switch that allowed me to do that ... BUT on the new to me camper I am purchasing I want to put a new solar array and power inverter in .. and I would like to do the same. BUT a little more simplistic. Was hoping this would do the trick.
So in A/C mode can I run shore power to it and have it keep my batteries charging while those batteries run 12v appliances ?
Yes...sort of. Typically your battery charger, batteries and 12V system will all be connected either directly or indirectly. So depending on your battery state of charge your charger and batteries may both power your 12V DC loads. The flow of energy will always be from the higher voltage source to the load.
I've been looking at this inverter. Can you run the inverter and turn on an AM Radio either battery powered or plug in and listen for any RFI (Radio Frequency Interference) static. Being a low frequency inverter I would be interested in how it performed under a load.
Didn't use an AM radio, but I have an RF meter which didn't register at any significant level until it got within a foot or so.
I have a 3000 watt pure sine inverter with a 24 volt system and 30 100w batterys why will it not charge my 2021 chevy bolt ev
Will this switch from the home AC to batteries before it fails? meaning if there are not enough Amps available on the homes circuit due to other loads on the circuit?
It will switch only when the voltage reaches the low voltage cut off level.
How it been so far?
If solar is involved.. would you simply hook up the solar charge controller on the battery terminal and charging can come either from inverter/charger and solar charger?
Any issues there?
Generally yes. I'd add a buss bar for both pos and neg where everything connects to.
Can I feed the battery bank with either AC grid power or my solar panels? I bought this unit with that intent, but now, I'm thinking I can't. Thanks.
Have you switched it to solar priority?
I have this exact inverter but I am having trouble with the shore power charging function. Does anyone know why that might be? It had initially started to charge but at some point shut down and will not start again. I have cut power, changed to a higher gauge cord to plug in shore power, and checked all connections.
It is functioning on shore power mode and showing everything coming in properly. It just won't switch to charge mode.
You might want to check into that for 3000w you need 4/0 wire for anything over a 3foot run of wire 2/0 for under 3ft this is nearly exact same inverter as the the aims inverter I have and at 3000w load your talking over 300amp draw 1/0 will not carry that and the inverter will get massive voltage droop causing even more amp draw and heat / strain on the inverter.
Tito, nice deep review. BTW, did you buy stock in the parent company of Unistrut?
I did ! :)
the LiFePO charge voltage seems low....most are 14.4 or 14.6v....
Yeah. That probably won't take it to 100% SOC but close. I've been trying some of the other profiles with these LiFePO4s 14.0-14.6. I like the AGM profile the best with the 14.1 bulk and 13.4 float.
I use the agm profile with my lifepo4 batteries and it seems to be working well
I have 100 AH 12 volt Battle Born Batteries.. I talked to their support guy and he said to use the seal lead acid setting. BB batteries need at least 14.2 volts to top balance.
@@EmanM45 Yup. I've been using the AGM setting which bulk charges at 14.4V.
Seems odd that they would have a lipo4 setting, however, you need to set it differently to charge lipo4. Sure, another profile would work, but it is a confidence breaker
Would you consider this a cost effective solution for RV use vs a victron?
Yes, if you need an inverter/charger. But it doesn't do everything a Victron Multiplus can do.
@@RVwithTito thank you very much sir. If I may pardon the ignorance. What would be missing compared to the victron?
Everyone comments that it is similar to an Aims. The Aims I have is 2000 watt with the transfer switch. If I connect it to a protected outlet, GFCI, it trips the protection of the outlet. My inverter generator has a protected outlet. Anyone know if this inverter does the same thing?
Ok I watched your video twice and did some research. SunGoldPower headquarter in China and will explain the less cost, currently going to $735 and offering free shipping and no tax until 31 Oct. My only concern, if you need tech support, then you need to wait until after 8 PM to contact someone on the east coast? I worked for Tech Support for IBM and my counterpart in China didn't start until 8PM, and I needed to start at 4 AM at the end of shift. I am concern about getting stuff from China. With the Supply Chain issue we are having now, if you order one how some will it here. My biggest concern is tech support for setup and will they be about to understand me.
Many of these manufacturers maintain inventory in the US and will ship from there. Mine arrived in about a week to 10 days.
Can you draw more than 30 amps at the same time on this inverter charger
Interesting............
Will that run a Dewalt 10" miter saw that draws 15 Amps?
Does it assit shore/genny power?
No. This one doesn't have a power assist feature like the Victron Multiplus does.
So what is the power it uses
Does this have any back flow prevention installed?
So this will work for solar only then if needed
Sure. Solar is actually unrelated to this part of the system.
Does your power go out alot ?
It can during this time of year...wind storms and trees and stuff.
