A good video guys but a few things you do or omit are not necessarily good advice. You cabled the two batteries together in parallel good but, the inverter and any solar controller should always go to positive of battery A and negative of battery B so both batteries draw equally. Fuses are required on all positive cables to protect the cables. Cable sizes need to be as short as possible and the guage needs to reflect power draw. For example that 1500W inverter is going to draw 125A with 250A start up surge so that needs 00AWG cable and 300A fuse. Pairing batteries should only be done after ensuring their condition SOH is virtually identical. I appreciate what you are trying to do but if you factor in the real cable cost, fuse cost, cable connectors etcetera your budget will be a lot higher. Mount the inverter on top of the box, not inside as it will get hot. Most have suggestions of gaps required. I have a 200AH LFP battery and 2000W inverter (240v here in Australia) and am going to build my own battery box. These aren't generators BTW as they merely convert 12V DC to 110v or in my case 240v AC supply. I like your plastic trolley box!

@@bobbygene8274what if there was a way to charge it as well. Like using an alternator magnets and copper wire? I seen a video a while back where someone created energy using those items. Very simple. I came across this video looking for that video.
As a 42 year Master Electrician I can validate this set up!!!!!!!! 100% spot on iv'e been doing it this way for years and years...... I currently have a 1500 Watt power inverter and a huge deep cycle marine battery with the Harbor Freight 100 Watt solar charging system....... It comes with the charge controller and the system works like a charm!!!!!! I can run my fridge and internet and some lights no problem..... No way I was going to spend a couple grand on something like you said I can build from the things I have available to me in my shop.... Great job guys!!!! Very useful and practical set up that will last years and years!!!!!!!
@@babyreps365 Absolutely but you cannot go over whatever wattage your inverter is.... And really you want to stay at around 50% max load so it will work longer and not strain the system..... 75% is ok but I try and stay at 50% or less
I am happy to find your comment as I am old and know nothing about solar usage in any way. My husband uses a cpap at night that uses about 350w and I use oxygen at night only. I would use my portable oxygen machine in a grid down situation and it uses about 350w. Between the two of us it would be 700-800w. We would use this maybe 8-10 hours at night. How many 100w solar panels would we need and about how long would it take to charge them on an average sun day in order to use it the next night. Would this homemade generator work for our needs. Are there tweaks to make to the generator. I sure hope you see my question and answer it. Thanks.
@@icecreamladydriver1606 Are you sure you don't mean the cpap machine would use 350Wh (watt hours)? From what I understand most only cosume about 40w to use. So 40x 8 hours = 320Wh which is different from 320W. If you meant watt hours instead of watts, then a 100Ah Deep cycle LifePO4 battery (100x 12.8v=1280Wh) would do you both for emergency backup for 8 hours. You would need a couple of panels and a charge controller to charge it back up during the day.
The best part of this video was watching you and your dad doing something together. My parents were heavy cigarette smokers 2-4 packs a day, the horse always had a smokey had inside, so at 21, I got married and moved put. I hated to visit them because of the disgusting cigarette smell. Looking back since both parents are dead now, I feel like a selfish pos that I didn't spend alot of time with my dad much. Enjoy your time with him.
*Thank you for sharing this valuable information in the video. I would like to add that used batteries can often be found in major cities for around $40, and Walmart also offers some batteries priced at $86. Overall, this is an excellent idea for DIY enthusiasts who, like myself, enjoy building projects.*
That works. Something to keep in mind though is that unlike LiIon those lead acid batteries don't like deep cycling. But if you only use the top 10-20% of capacity, it's a great way to go.
If you use marine batteries or golf cart batteries they are made for deep discharge and are only a little more than regular car batteries or use gel cell but those are expensive
Yeah. Those will help. My recommendation is to go Lifepo4 if the budget allows for it, as they will most definitely pay for themselves in the long term. On the other hand Lifepo4 isn't as forgiving to high temperatures, which cuts into their cycle life. So if things might get hot where the battery is stored and used, Lifepo4 might not be the way to go. YMMW.
You also need to use the right "float" charge when they are not being actively used or mainline charged after being used. The right float charge varies not only on the battery technology, but can vary depending on manufacturer. Not using the right float charge will significantly reduce the lifespan of a battery. Note: I've seen UPS units by highly respected UPS manufacturers that use MUCH too high float charges on their "gel-cell" batteries, which seriously reduces their battery life from what could be well over 5 years to less than 3 years. edit to add: Of course, they are happy to sell you replacement battery(ies) at usually quite high cost (sometimes using proprietary connectors to try to force one to buy only their replacement pack(s)).
There can be some issues with charging batteries in parallel. Ideally you should be using a balanced charger, and the batteries should be the same chemistry, capacity, and approximate condition. For periodic use, it's not going to make a big difference. But if you're using a DIY power station regularly, batteries will fail sooner when they're not properly balanced. Search for "charging 12v batteries in parallel", there's a bunch of articles on the topic.
@@Mr.J345no, they are correct. Series is far more difficult of course, but parallel has specific wiring considerations to keep them at the same level of charge and discharge.
From what the "Power Queen" batteries (the ones used by these folks) product page shows, it looks like each LiFePO4 battery has its OWN BMS, so as long as the user is providing the correct voltage and power requirements, and an appropriate amount of charging, one shouldn't have to worry about balancing and so on. However, when initially connecting the packs together, I would ensure they are very close in state of charge to each other to prevent high currents/sparks in the cables when first connecting them together...and when in use you may want to ensure each battery alone could handle the expected load because the BMS of a depleted battery pack may "shut off" one battery pack, leaving the other(s) to supply all the power (although ideally if there is an overload the remaining batteries' BMS controllers should also in theory disconnect those batteries due to potential overload.
Series charging is the thing that is difficult. For parallel charging, just make sure that the path to each battery is the same length. If you have a string of batteries in parallel in a row, connect to positive to the battery one end of the row, and the negative to the battery at the other end of the row. Make sure all the cables from the battery bank are the same length.
Even with Bluetti's 2048Wh AC200 on sale for like $1150 ish for prime day, which is actually incredible and hard to pass up, it's just extremely important to me to be able to easily replace broken parts. If something breaks in that thing, you might be out $1150.
Thanks...Just caught this one. You did a great job. Now I'm near 70 and just started my U-Tube. "Tinkering Geezer". You fellows made it look PROFESIONAL. WOW
We have used the ua-cam.com/users/postUgkxOTeIs0vv4_9B5hsmnLsk9r930uDQLu_Y for probably 30 hours with our camper and it’s been great! The noise level is really only noticeable when running the AC and other appliances like the microwave, hair dryer, or coffee pot. It’s not huge like other ones and it has wheels so even at 90lbs, I can move it!
Got my 305 lipo4 set for about 500 dollars. Also make sure you are getting pure sine wave inverter. The modified ones can burn up some electrics. I am making a 305 ah (about 4kwh) with pv and 2000watt for a little over 1000.
@@yelowfruit Battery Hookup has 20S CATL modules made with uncycled 280Ah cells. They are 2 years old but will give full capacity and after a few cycles should give your typical 285Ah+ of new cells. I'd guess IR is probably a tad higher than normal but for an ESS its perfect. I think it comes out to $85 a cell which is dirt cheap for Grade A CATL cells (ok these might be considered high quality Grade B since they are NOS) Downside is you have to buy 2 20S modules to get that price. If you buy 4 20S modules that means you can cut the bus bars on the 4 batteries you don't use for the 16S 48V system (best voltage to use as its most common) and then string together the 4 sets of 4 to create a 5th battery . Someone here on UA-cam has a great video on doing it. Yes, its several thousand dollars but each 16S battery is 14kwh....so four modules would give you 70kwh which is more than enough to run a house for days including AC and hot showers.
305Ah cells, a 2000W inverter and how much PV for under $1k? I know you get those cells from 18650 Battery Store for about $120 if you don't mind high quality Grade B but shipping is going to be another $150. The cheapest 2000W pure sine wave inverter is $175 and even if you use used solar panels 2kw of solar will run you a couple hundred dollars. Then you need a charge controller and thats another $100 minimum.
Lots of money but for someone like me that is worried about anything electrical it dubs the job for me great job on the video just wish I could do my own 😊
Great video! The inverter in the name brand generator is probably a pure sine wave witch is better and more expensive. Something to keep in mind for your electronics. I have been thinking about getting one but I can’t justify the cost. Great video on a cheaper option. Any power is better than no power
Both the 2000W and 3000W Renogy inverters pointed to by Brock/Keith claim "Renogy 2000W *_Pure Sine Wave_* Inverter 12V DC to 120V AC" "Renogy 3000W *_Pure Sine Wave_* Inverter 12V DC to 120V AC"
Good basic how to, but...1 LiFePO4 100 amp hour battery has more capacity than 2 lead acid, weighs 20 to 25 pounds and will last ten years. The cost is around $300. The max output of 1 would be 1200 watts, so you need two to run 1200 to 2400 watts. If you are starting from scratch and have to buy new batteries, I strongly suggest buying a LiFePO4. You can tip them over and not worry about spilling acid, you can safely use them and store them inside your house, you can run them down all the way and maintain most of the voltage until the very end, and they are so much easier to tote around.
@@keithmaggard9024 I just replaced the deep cycle lead acid in my shed with a LiFePO4 for $165. It's crazy how much they've dropped. 48 volts have really come down too.
This is much simpler and I can just go ahead and upgrade my car battery early and use that to build my backup battery. Thank you very much to you and to your Dad!
Car batteries aren't ideal as they are not designed to deep cycle. Their plates are positioned to allow high cranking amps for a starter motor then rely on the alternator replenishing the power. Buy marine or camping deep cycle. Better still buy LFP which is half the weight and can get the full amp hours out of them. Lead acid batteries of 100Ah only have 50 usable amps before getting down to 12v. After that if not recharged immediately they degrade rapidly.
For my tractors I use Grover technology. 12 V. Capacitors where I don't need a battery to start my tractor. Victron charge controllers with solar panels do really nicely with inverters and batteries Good video
Tip for your steel building: I use "sleeve nuts" on the inside of the shell to mount wiring, hang compressed air hose and much more. My Steelmaster uses 5/16" bolts so I use matching sleeve nuts. I anti-seized all the bolts when I erected mine which paid off when I got orders because it was a breeze to tear down then reassemble at my new location.
Howdy Brock and Keith! Really cool how-to video. Shows what can be done on a budget. A couple homesteaders I follow made something similar. I'd like to make one eventually... be a lot quieter and lighter than toting a generator around the property where I might be needing power for a short time. Thanks for sharing 🤠
when you connect the inverter you should always connect to positive on one battery and negative on the other one (this will draw and charge evenly from both batteries and prevent you damaging 1 battery or both)
🤣Not literally friend, a way of melting divides among us. Besides your sharing such important information seems very neighborly. A good thing. Thank you @@RockhillfarmYT
Made one years ago, tool box with a truck battery in it. Everything wired through a low voltage cut off so I didn't over drain the lead acid battery. After taking it camping about 3 times I was tired of lugging the damn thing around 😂
What an excellent idea. I have one spare deep cycle battery and a pure sinewave inverter. I think I'll hook them together and give this a try. I live in the California mountains and our power company gave warnings that they may shut off the power yesterday and today due to high winds. So far, no shut off.
I use a CPAP and I used to take an RV battery and inverter with me when I went tent camping (I have a camper now, with its own battery). An RV battery will take a deeper discharge than a standard car battery.
You can usually purchase used solar panels from your local solar farm as they replace them yearly and at that point your getting a commercial grade solar panel for next to nothing
Rock - Great video, very useful. I too can not justify (regardless of whether I can afford it or not) spending 3K for something I would only use occasionally. Are the high-end units nice, of course. Do they make financial sense for ME, not. For the record, I put in a Kohler 20Kw whole house generator with automatic transfer for switch for like 5K a few years ago. Looking at that comparison alone should give a good sense of value. However, I do give the manufacturing world credit for being able to teach the Gen Z'ers that they actually need this... Smile. Thanks for bringing us all alone. Great Video !!!
Im looking into making something like this using 2 H.F. batteries 35A/H ea. and a solar panel, controller, inverter and case for running a cpap machine independently while camping. This video was exactly what I was looking for. I think the 100W panel will recharge batteries just fine if im getting 6hrs sleep using the machine.
I have a small one set up on a shop that isn't located near my house I use it for lights and fire up the generator on the occasion that I need more it keeps me from spending a fortune on wiring and paying a monthly minimum on a building I don't use much.
this is what im going to do once i finish my house. reuse my current system from this old camper and use my craftsman tool box the wife got me years ago.
I have both set ups. A Bluetti 200Max generator then my own set up. Renogy solar charge controller. 2 agm batteries and a 3k watt power inverter from harbor freight. The Inverter is not pure sine wave and I’m scared to plug anything into it,,specially small items like charging laptop and phone. Since I have the Bluetti my homemade set up I’d only for emergency use. Don’t want all that weight and used up space in my cargo trailer that is off grid. 😊 Thanx for the rolling battery cart idea.
Not a bad price point considering how much folks probably already have laying around. I could build one today with all the stuff sitting in my little shop.
@trentbishop7793 Just like the name implies, the voltage varies from + to negative 60 times a second. lights transformers, and most motors don't care, but it can play hell on some electronics. Google sine wave vs. square wave and you will see what I mean! Hope this helps.
I built mine in a cooler like that with two marine batteries and a 2001 inverter and another inverter lights wiring gauges and it works fine and my solar panels are outside ready to be plugged in
The loose end of that positive flailing around made me nervous LOL! I use a 3 inch piece of heat shrink tubing, tape one end closed and slip it on the end of the cables I am working with. No chance of touching the wrong power post. I have a few made up ahead of time so when I need to connect or disconnect the cables, I slip the appropriately colored tubing on the loose end.
I think we may be missing the point i have thrown one of these together ina few minutes during a power outage out of things i had and that exact geniverse with pannels list for 3700 it is an amazingly powerful product we aren't really saying something put together on the cheap is better but it ain't bad for the price

Nice video. A year later things have changed a bit. I just picked up 2 x 100Ah LifePO4 for $328 total from Redodo. They are the larger ones with low temp monitoring, 5 year warranty, 4000 deep cycle charge, and have the carrying straps. So 2560Wh worth of backup. I was attempting to do exactly what you guys are doing here. I like that you put it all in a rolling cart. I got a 1000w (2000peak) inverter and 2x 200w Bifacial panels for charging ($285 total for panels) with a Redodo 40A MPPT charge controller for $129. I could add a 17gal Craftsman rolling tool box with 200lb capacity for about $52 and I would have a pretty decent backup/mobile powerstation. And that would bring me in around $893 today. I COULD buy a generator for that. But then I have the carbureator and all to clean and deal with, and need gas to run it (we found out with Helene here in NC gas stations don't have gas when all the power gets knocked out!) I really like this option of building your own. You get more bang for the buck, it's expandable, AND you customize it more to your needs.
There's a couple of guys on UA-cam saying they're small inverter runs their air conditioner and I try to not argue with them but it takes quite a bit for an AC to start.
Best to use Marine Batteries designed for heavy duty use plus they can afford to go very low on voltage. Already made Power Bank is safer& compact as well as efficient.
A long way from ideal I put an old Car Battery I had in an old Cooler I had then mounted an Inverter I had to the lid of the Cooler,...Ran my Internet Router/Gateway for 8 hours with more to spare :)
LIFEPO4 batteries like what are used in nicer commercially-available power stations are safe for indoor use, charging/discharging lead-acid batteries can release gas - might not want hydrogen gas in your home - Also something to keep in mind when in a box like that when housing certain types of batteries that can produce gasses. If kept in a sufficiently vented garage or shed or something, deep-cycle lead acid batteries are a great choice with a MPPT controller.
I think people missed the point of the video... most aren't looking to run their expensive electronics daily from this, they want to run a fan on a camping trip or power a gas furnace during a winter emergency. It does exactly what it was needs to do.... cheaply
Exactly. If you’re planning to use this all day all the time to live off grid, you should buy an expensive unit. If you just wanna plug something in every once in a while, save some money
This set up is fine, if you are using 2 used lead acid car batteries laying around. But you can't mix regular car batteries with deep cycle batteries, or lead acid with LiPo batteries. And if you have a used regular car battery, and a new, or newer deep cycle battery, you will reduce the deep cycle batteries lifespan. It would be better to only use deep cycle batteries for this type of use, and put trickle chargers on your tractor and whatever else you have on the farm. We take every battery out of the farm equipment that isn't used during the winter months, and keep them indoors, and individually hooked up to trickle chargers. We made 4 of these, and made sure the batteries were compatible with each other, by charging them up, and checking the voltage the next day, and putting batteries together that were the same voltage, or the most closest to each other. There is a charging station for the portable power carts, like the one these guys made. We have both solar and wind turbines. So, no matter what, we have a source of power to charge things, and run hous3 and shop power. We also have a good wood heater that has a pellet feeder, to keep it burning at night, when nobody can feed it chunks of wood. And this saves us a lot of money for warmth. Summer we use a water Solar heater, hooked up to a 24v power. We are also making a couple power walls, like Tesla sells. And use 18650 batteries.
Awesome video!!.. I was just thinking about getting a solar generator because my generator so loud. My RV have panels on top and a whole system that charges itself and I got thinking to myself with everything I have I probably have everything I need I have two inverters a bunch of marine batteries ect. Even have like five extra panels.. I figured that's all that those things were. . Thanks for breaking it down I was overcomplicating it
I have thought about doing this for my corn burner stove. I would make a quick disconnect for the inverter, so I could use it on my truck for "portable" power when needed. "My truck" is a 1995 E350 with 7.3 diesel and has a HUGE alternator( it was a cab chassis with an ambulance box on back when new). I'm not sure of the amperge output, but I imagine it's pretty healthy.
Make sure you are getting an inverter that is pure sine wave if you are plugging in sensitive electronics. I am not sure if Harbor freight is making pure sine wave inverters yet, maybe.
Nice piece of work you have done there...but I do have something to say to it. First those plastic zip-tigts can melt because of heat the inverter can emit when in use and second when you drill those holes at the top of the box you are losing water-proof features of the box itself so the water can run into it in heavy rains ( of course there should be some holes or vents on sides with some gap above it to prevent rain dripping into it). Anyway nice piece of work you done there and I hope that you inspired lot of peoples.
You really should consider putting fuses on the output of the battery. I built one of these about 20 years ago. I wish I could send you pictures. I made it on a battery box.
To add to my previous comment is the convenience of recharging the already assembled Power Bank via Household Current(110V/US)or 12V Auto socket in addition to the Solar Panels Input whichever is available.

That works. Something to keep in mind though is that unlike LiIon those lead acid batteries don't like deep cycling. But if you only use the top 10-20% of capacity, it's a great way to go.
If you use marine batteries or golf cart batteries they are made for deep discharge and are only a little more than regular car batteries or use gel cell but those are expensive
Yeah. Those will help.
My recommendation is to go Lifepo4 if the budget allows for it, as they will most definitely pay for themselves in the long term.
On the other hand Lifepo4 isn't as forgiving to high temperatures, which cuts into their cycle life. So if things might get hot where the battery is stored and used, Lifepo4 might not be the way to go. YMMW.
You also need to use the right "float" charge when they are not being actively used or mainline charged after being used. The right float charge varies not only on the battery technology, but can vary depending on manufacturer. Not using the right float charge will significantly reduce the lifespan of a battery.
Note: I've seen UPS units by highly respected UPS manufacturers that use MUCH too high float charges on their "gel-cell" batteries, which seriously reduces their battery life from what could be well over 5 years to less than 3 years.
edit to add: Of course, they are happy to sell you replacement battery(ies) at usually quite high cost (sometimes using proprietary connectors to try to force one to buy only their replacement pack(s)).
There can be some issues with charging batteries in parallel. Ideally you should be using a balanced charger, and the batteries should be the same chemistry, capacity, and approximate condition. For periodic use, it's not going to make a big difference. But if you're using a DIY power station regularly, batteries will fail sooner when they're not properly balanced. Search for "charging 12v batteries in parallel", there's a bunch of articles on the topic.
Like when a tractor or diesel truck require 2 batteries. Same thing.
Your thinking series connection. Parallel requires no balancing
@@Mr.J345no, they are correct. Series is far more difficult of course, but parallel has specific wiring considerations to keep them at the same level of charge and discharge.
From what the "Power Queen" batteries (the ones used by these folks) product page shows, it looks like each LiFePO4 battery has its OWN BMS, so as long as the user is providing the correct voltage and power requirements, and an appropriate amount of charging, one shouldn't have to worry about balancing and so on.
However, when initially connecting the packs together, I would ensure they are very close in state of charge to each other to prevent high currents/sparks in the cables when first connecting them together...and when in use you may want to ensure each battery alone could handle the expected load because the BMS of a depleted battery pack may "shut off" one battery pack, leaving the other(s) to supply all the power (although ideally if there is an overload the remaining batteries' BMS controllers should also in theory disconnect those batteries due to potential overload.
Series charging is the thing that is difficult. For parallel charging, just make sure that the path to each battery is the same length. If you have a string of batteries in parallel in a row, connect to positive to the battery one end of the row, and the negative to the battery at the other end of the row. Make sure all the cables from the battery bank are the same length.
I like your video but i love your father`s t-shirt inscription: " We walk by faith not by sight "! Amen! Blessings from Greece !
I did that ! Powered my in attached garage with 2 I00 watt solar panels via 2 Deep cycle boat batteries & 4000 watt inverter.
Even with Bluetti's 2048Wh AC200 on sale for like $1150 ish for prime day, which is actually incredible and hard to pass up, it's just extremely important to me to be able to easily replace broken parts. If something breaks in that thing, you might be out $1150.
Thanks...Just caught this one.
You did a great job.
Now I'm near 70 and just started my U-Tube. "Tinkering Geezer".
You fellows made it look PROFESIONAL.
WOW
Best of luck to you and making videos. Feel free to reach out if I can help in anyway.

We have used the ua-cam.com/users/postUgkxOTeIs0vv4_9B5hsmnLsk9r930uDQLu_Y for probably 30 hours with our camper and it’s been great! The noise level is really only noticeable when running the AC and other appliances like the microwave, hair dryer, or coffee pot. It’s not huge like other ones and it has wheels so even at 90lbs, I can move it!
yea those inverters
Got my 305 lipo4 set for about 500 dollars. Also make sure you are getting pure sine wave inverter. The modified ones can burn up some electrics. I am making a 305 ah (about 4kwh) with pv and 2000watt for a little over 1000.
Just made a long ass comment about how cheap it is to put together a 4kwh battery with prismatic cells. Can't believe more people dont know.
where?
@@yelowfruit Battery Hookup has 20S CATL modules made with uncycled 280Ah cells. They are 2 years old but will give full capacity and after a few cycles should give your typical 285Ah+ of new cells. I'd guess IR is probably a tad higher than normal but for an ESS its perfect. I think it comes out to $85 a cell which is dirt cheap for Grade A CATL cells (ok these might be considered high quality Grade B since they are NOS)
Downside is you have to buy 2 20S modules to get that price. If you buy 4 20S modules that means you can cut the bus bars on the 4 batteries you don't use for the 16S 48V system (best voltage to use as its most common) and then string together the 4 sets of 4 to create a 5th battery . Someone here on UA-cam has a great video on doing it.
Yes, its several thousand dollars but each 16S battery is 14kwh....so four modules would give you 70kwh which is more than enough to run a house for days including AC and hot showers.
305Ah cells, a 2000W inverter and how much PV for under $1k?
I know you get those cells from 18650 Battery Store for about $120 if you don't mind high quality Grade B but shipping is going to be another $150. The cheapest 2000W pure sine wave inverter is $175 and even if you use used solar panels 2kw of solar will run you a couple hundred dollars. Then you need a charge controller and thats another $100 minimum.
We built a better version here
Build a Better Solar Generator for 1/2 the Price!
ua-cam.com/video/Gxh_2U_fSN0/v-deo.html
Lots of money but for someone like me that is worried about anything electrical it dubs the job for me great job on the video just wish I could do my own 😊
Great video! The inverter in the name brand generator is probably a pure sine wave witch is better and more expensive. Something to keep in mind for your electronics. I have been thinking about getting one but I can’t justify the cost. Great video on a cheaper option. Any power is better than no power
Hello good morning to you
Both the 2000W and 3000W Renogy inverters pointed to by Brock/Keith claim "Renogy 2000W *_Pure Sine Wave_* Inverter 12V DC to 120V AC"
"Renogy 3000W *_Pure Sine Wave_* Inverter 12V DC to 120V AC"
Good basic how to, but...1 LiFePO4 100 amp hour battery has more capacity than 2 lead acid, weighs 20 to 25 pounds and will last ten years. The cost is around $300. The max output of 1 would be 1200 watts, so you need two to run 1200 to 2400 watts. If you are starting from scratch and have to buy new batteries, I strongly suggest buying a LiFePO4. You can tip them over and not worry about spilling acid, you can safely use them and store them inside your house, you can run them down all the way and maintain most of the voltage until the very end, and they are so much easier to tote around.
Your right and at the time we put this together lifepo4 batteries were still very expensive but the price has dropped dramatically
@@keithmaggard9024 I just replaced the deep cycle lead acid in my shed with a LiFePO4 for $165. It's crazy how much they've dropped. 48 volts have really come down too.
THis is, by far, the best DIY solar system video I have ever seen on the internet. Nice work you guys!
Good Idea Brock. That inverter has a cooling fan, do not run with the lid closed unless you add ventilation.
I like your shirt .We walk by faith ,not by sight.
Amen!
This is much simpler and I can just go ahead and upgrade my car battery early and use that to build my backup battery. Thank you very much to you and to your Dad!
JFYI Car batteries don't live very long as a power source that will be deep cycled like this! These things KILL starter batteries!
Car batteries aren't ideal as they are not designed to deep cycle. Their plates are positioned to allow high cranking amps for a starter motor then rely on the alternator replenishing the power.
Buy marine or camping deep cycle. Better still buy LFP which is half the weight and can get the full amp hours out of them.
Lead acid batteries of 100Ah only have 50 usable amps before getting down to 12v. After that if not recharged immediately they degrade rapidly.
For my tractors I use Grover technology. 12 V. Capacitors where I don't need a battery to start my tractor. Victron charge controllers with solar panels do really nicely with inverters and batteries Good video
Great help may the Lord bless
Tip for your steel building: I use "sleeve nuts" on the inside of the shell to mount wiring, hang compressed air hose and much more. My Steelmaster uses 5/16" bolts so I use matching sleeve nuts. I anti-seized all the bolts when I erected mine which paid off when I got orders because it was a breeze to tear down then reassemble at my new location.
Howdy Brock and Keith! Really cool how-to video. Shows what can be done on a budget. A couple homesteaders I follow made something similar. I'd like to make one eventually... be a lot quieter and lighter than toting a generator around the property where I might be needing power for a short time. Thanks for sharing 🤠
when you connect the inverter you should always connect to positive on one battery and negative on the other one (this will draw and charge evenly from both batteries and prevent you damaging 1 battery or both)
you are very smart people. thank you so much. God bless!
This is so good for people like me with no idea. Thanks.
👍Thank you neighbor, this video is really helpful could be a life saver 👍
My neighbor?
🤣Not literally friend, a way of melting divides among us. Besides your sharing such important information seems very neighborly. A good thing. Thank you @@RockhillfarmYT
This is a very helpful video. Great job, guys! Thanks for sharing. Take care 👍
Great job of breaking it down it is the best video on the subject I've ever seen
Thanks. We did a follow up with some better components

ua-cam.com/video/Gxh_2U_fSN0/v-deo.html
yo dope video!!!! shout out to your dad for his knowledge and experience!!!! So cool!!!!!!
Made one years ago, tool box with a truck battery in it. Everything wired through a low voltage cut off so I didn't over drain the lead acid battery.
After taking it camping about 3 times I was tired of lugging the damn thing around 😂
What an excellent idea. I have one spare deep cycle battery and a pure sinewave inverter. I think I'll hook them together and give this a try.
I live in the California mountains and our power company gave warnings that they may shut off the power yesterday and today due to high winds. So far, no shut off.
I use a CPAP and I used to take an RV battery and inverter with me when I went tent camping (I have a camper now, with its own battery). An RV battery will take a deeper discharge than a standard car battery.
You can usually purchase used solar panels from your local solar farm as they replace them yearly and at that point your getting a commercial grade solar panel for next to nothing
Nice video. In Australia your dad would be known as a bush mechanic. Just gets it done!
Rock - Great video, very useful. I too can not justify (regardless of whether I can afford it or not) spending 3K for something I would only use occasionally. Are the high-end units nice, of course. Do they make financial sense for ME, not. For the record, I put in a Kohler 20Kw whole house generator with automatic transfer for switch for like 5K a few years ago. Looking at that comparison alone should give a good sense of value. However, I do give the manufacturing world credit for being able to teach the Gen Z'ers that they actually need this... Smile. Thanks for bringing us all alone. Great Video !!!
You can find used 300-400 watt solar panels on market place and similar for 50-75 bucks a panel. Perfect for s project like this!
So educational and helpful! Appreciate you guys!!
Im looking into making something like this using 2 H.F. batteries 35A/H ea. and a solar panel, controller, inverter and case for running a cpap machine independently while camping. This video was exactly what I was looking for. I think the 100W panel will recharge batteries just fine if im getting 6hrs sleep using the machine.
I have a small one set up on a shop that isn't located near my house I use it for lights and fire up the generator on the occasion that I need more it keeps me from spending a fortune on wiring and paying a monthly minimum on a building I don't use much.
this is what im going to do once i finish my house. reuse my current system from this old camper and use my craftsman tool box the wife got me years ago.
I subscribed because of this video for my pop up camerer that I live in
Nicely done . Planning on building something like it soon . Want to be able to camp off grid or boondocks as some call it . Thanks .
LiTime has a 100 amp hr battery for $250. I have 3 of them and they are awesome .
I have both set ups. A Bluetti 200Max generator then my own set up. Renogy solar charge controller. 2 agm batteries and a 3k watt power inverter from harbor freight. The Inverter is not pure sine wave and I’m scared to plug anything into it,,specially small items like charging laptop and phone. Since I have the Bluetti my homemade set up I’d only for emergency use. Don’t want all that weight and used up space in my cargo trailer that is off grid. 😊 Thanx for the rolling battery cart idea.
Not a bad price point considering how much folks probably already have laying around. I could build one today with all the stuff sitting in my little shop.
Don't recommend for electronics due to the modified square wave output. But for most tools and lights it will work fine!
@trentbishop7793 Just like the name implies, the voltage varies from + to negative 60 times a second. lights transformers, and most motors don't care, but it can play hell on some electronics. Google sine wave vs. square wave and you will see what I mean! Hope this helps.
Aka dirty electricity
EXCELLENT EXCELLENT EXCELLENT !
That was a great video guys.
I built mine in a cooler like that with two marine batteries and a 2001 inverter and another inverter lights wiring gauges and it works fine and my solar panels are outside ready to be plugged in
Can you do a video on that set up! Sounds like you did the right thing!
The loose end of that positive flailing around made me nervous LOL! I use a 3 inch piece of heat shrink tubing, tape one end closed and slip it on the end of the cables I am working with. No chance of touching the wrong power post. I have a few made up ahead of time so when I need to connect or disconnect the cables, I slip the appropriately colored tubing on the loose end.
Maybe some ventilation for the lead acid batteries would be good
Pure Sine Wave Power inverters are the new big thing. ...but great video.
I agree this video we used what was readily available in our area or in this case we already had.
I think we may be missing the point i have thrown one of these together ina few minutes during a power outage out of things i had and that exact geniverse with pannels list for 3700 it is an amazingly powerful product we aren't really saying something put together on the cheap is better but it ain't bad for the price
you both seem special to say the least... take that as you want it.

Just sub due to your dads shirt. First time viewer less than 2min in
I LOVE your shirt! ✝
I'm going to do this. Wow!! We need this in Florida
did it work? thinking of trying it myself.
@@stephtheforgewitch No as easy as seen in the video but it did work yes
@@centralfloridagmrs incredible, thank you. if you have the time would it be alright if i asked what modifications you made?
Nice video. A year later things have changed a bit. I just picked up 2 x 100Ah LifePO4 for $328 total
from Redodo. They are the larger ones with low temp monitoring, 5 year warranty, 4000 deep cycle charge, and have the carrying straps. So 2560Wh worth of backup. I was attempting to do exactly what you guys are doing here. I like that you put it all in a rolling cart. I got a 1000w (2000peak) inverter and 2x 200w Bifacial panels for charging ($285 total for panels) with a Redodo 40A MPPT charge controller for $129. I could add a 17gal Craftsman rolling tool box with 200lb capacity for about $52 and I would have a pretty decent backup/mobile powerstation. And that would bring me in around $893 today. I COULD buy a generator for that. But then I have the carbureator and all to clean and deal with, and need gas to run it (we found out with Helene here in NC gas stations don't have gas when all the power gets knocked out!) I really like this option of building your own. You get more bang for the buck, it's expandable, AND you customize it more to your needs.
very good option for dig. thank you
This was a very helpful video, thanks for making it.
Watching now. Love your Dad's walk by faith shirt. Preparing for the coming days!
There's a couple of guys on UA-cam saying they're small inverter runs their air conditioner and I try to not argue with them but it takes quite a bit for an AC to start.
Best to use Marine Batteries designed for heavy duty use plus they can afford to go very low on voltage. Already made Power Bank is safer& compact as well as efficient.
100 Ah lithium phosphate batteries are now available on Amazon for $229. I recently replaced my car battery and it cost over $200.
Nice to have a cheap DIY solar generator, but it is way better to have a cheap and also a safe one while saving thousand..
Thank you so much
A long way from ideal I put an old Car Battery I had in an old Cooler I had then mounted an Inverter I had to the lid of the Cooler,...Ran my Internet Router/Gateway for 8 hours with more to spare :)
Awesome information! Thanks for the killer video! It’s definitely worth saving time and money
Thanks
LIFEPO4 batteries like what are used in nicer commercially-available power stations are safe for indoor use, charging/discharging lead-acid batteries can release gas - might not want hydrogen gas in your home - Also something to keep in mind when in a box like that when housing certain types of batteries that can produce gasses. If kept in a sufficiently vented garage or shed or something, deep-cycle lead acid batteries are a great choice with a MPPT controller.
outstanding
That was helpful, practical and simple; THANKS
Thanks
I think people missed the point of the video... most aren't looking to run their expensive electronics daily from this, they want to run a fan on a camping trip or power a gas furnace during a winter emergency. It does exactly what it was needs to do.... cheaply
Exactly. If you’re planning to use this all day all the time to live off grid, you should buy an expensive unit.
If you just wanna plug something in every once in a while, save some money
Add 12V ports and then you can also charge from your vehicle and easily use 12V accessories. USB ports are a useful as well.
The inverter has usb ports the 12 volt is a great idea
A 50ah LiFePo4 is now less than $200 now and will out last the 2 lead/acid batteries you have. Nice build anyway. Greetings from Jamaica.
this is excellent. thanks fellas
Thanks
LOVE THE SHIRT!!!
Thanks Rockhill! Great Info!
Holy crap! @4:49 that was a close call!!! Watch that wire almost hit the negative terminal freaked me out!
I would think that you would still have to open the lid so the inverter can stay cool running it's fan. You don't want it overheating!
Or you could cut a vent hole
Hi, I apologize for my manners for being too rude to leave a
comment on your comment box without your consent. You always
share great posts here,
This set up is fine, if you are using 2 used lead acid car batteries laying around.
But you can't mix regular car batteries with deep cycle batteries, or lead acid with LiPo batteries.
And if you have a used regular car battery, and a new, or newer deep cycle battery, you will reduce the deep cycle batteries lifespan.
It would be better to only use deep cycle batteries for this type of use, and put trickle chargers on your tractor and whatever else you have on the farm.
We take every battery out of the farm equipment that isn't used during the winter months, and keep them indoors, and individually hooked up to trickle chargers.
We made 4 of these, and made sure the batteries were compatible with each other, by charging them up, and checking the voltage the next day, and putting batteries together that were the same voltage, or the most closest to each other.
There is a charging station for the portable power carts, like the one these guys made.
We have both solar and wind turbines. So, no matter what, we have a source of power to charge things, and run hous3 and shop power.
We also have a good wood heater that has a pellet feeder, to keep it burning at night, when nobody can feed it chunks of wood. And this saves us a lot of money for warmth.
Summer we use a water Solar heater, hooked up to a 24v power.
We are also making a couple power walls, like Tesla sells. And use 18650 batteries.
Awesome video!!.. I was just thinking about getting a solar generator because my generator so loud. My RV have panels on top and a whole system that charges itself and I got thinking to myself with everything I have I probably have everything I need I have two inverters a bunch of marine batteries ect. Even have like five extra panels.. I figured that's all that those things were. . Thanks for breaking it down I was overcomplicating it
Thank you for this!
The gentleman has my favorite bible verse on the shirt🙏✝️
I have thought about doing this for my corn burner stove. I would make a quick disconnect for the inverter, so I could use it on my truck for "portable" power when needed. "My truck" is a 1995 E350 with 7.3 diesel and has a HUGE alternator( it was a cab chassis with an ambulance box on back when new). I'm not sure of the amperge output, but I imagine it's pretty healthy.
In a power outage I rigged one up to run my parents pellet stove so they would have heat
During a power outage I set one up to run my parents pellet stove so they would still have heat
As Americans, I like the way Americans think. Your the greatest !
Make sure you are getting an inverter that is pure sine wave if you are plugging in sensitive electronics. I am not sure if Harbor freight is making pure sine wave inverters yet, maybe.
They have one
Very good information.
Nice piece of work you have done there...but I do have something to say to it.
First those plastic zip-tigts can melt because of heat the inverter can emit when in use and second when you drill those holes at the top of the box you are losing water-proof features of the box itself so the water can run into it in heavy rains ( of course there should be some holes or vents on sides with some gap above it to prevent rain dripping into it).
Anyway nice piece of work you done there and I hope that you inspired lot of peoples.
You can buy reconditioned batteries at auto salvage yards. for $50 or $40 with core. Good as new. 😊
Hi Brock! Now you know. Mike Morgan uses a leaf blower to redistribute his sawduust at his sawmill.. Ha!
Mike is awesome. I’ll be doing a little trial and error to find out what works best.
You really should consider putting fuses on the output of the battery.
I built one of these about 20 years ago. I wish I could send you pictures. I made it on a battery box.
To add to my previous comment is the convenience of recharging the already assembled Power Bank via Household Current(110V/US)or 12V Auto socket in addition to the Solar Panels Input whichever is available.
