Building a 3.5kWh DIY Solar Generator for $650 - Start to Finish

23 827
After having a friend ask several questions regarding a solar generator project he was working on, I decided this would be a good opportunity to build my own solar generator and fully document the process. The total build came out to around $641. This video provides an in-depth look at the process involved in collecting and assembling the battery pack along with the choice of components and some testing.

By any chance do you have a store where one can buy all the parts? Like a kit! If not it’d be great to have one along with a step by step guided video to go along with the parts one bought. Nice work 👍

It is very dangerous not to use a fuse in home batteries or solar systems. I recommend you use fuse cable or car fuses in the series connections so the line will be canceled and the broken battery will not act as a resistance so it cannot catch fire. You will have to calculate the maximum amps that correspond to the connections, it is not your fault in the future when the lithiums begin to fail there will be many fires in houses that have commercial batteries. Regards.

How much does this thing weigh? I have a bad back and may need to build this in a toolbox with wheels and a handle. Great Video!
LithiumSolar - 21 time siden
It weighs 57lbs, quite heavy. I know they had a variety of different toolboxes, including some with wheels.

Nice work Mister, but I'm worried about the sheer amount of heat generating hardware in such a small volume. Thermal runaway looms as a nightmare risk. You have probably - by now - soak-tested the setup to see how a continuous loaf affects internal temperature. What kind of rise above ambient did you note?

This was so cool. Liked and subbed. One suggestion: make a video where you DO show how you mounted and wired everything up in that box. There's no problem with having another video on this build. Some people who watch this video (which is information-dense and definitely not too long) will see everything and be able to fill in the details. But many others, like me, would benefit from seeing how you actually put everything together piece-by-piece, and a second video would be perfect for that.
As the generator has already been built, even just a follow up video where you kind of disassemble it it a bit and point out what you did and how you did it would be superb. There's a lot to be learned by watching how someone who knows what they're doing approaches an assembly like this in addition to just the exact instructions.

Awesome video on solar DIY. I have always been a keen project maniac on such for a long time but have not done so. After watching your video I will now be giving it a try. I will surely need your assistance in this type of project.

1200 watt inverter assuming 120 volts gives you 12.5 amps at the output. Why did you put four outlets at 15 amps? Maybe a label warning not to exceed 1500W/12.5A.
It would have been cool to run it hot to prove the fan sub-system worked. Since the build, have you ran it hot? And is the cooling system adequate to bring the temps back down (or keep it at a safe level)?
*Overall, your video answered a lot of questions for me and gave me the courage to build one. Thanks for putting this out there.

Everything I have ever read about battery safety says that this battery design is a very high energy fire bomb waiting to happen. Has the basics of battery performance and safety been debunked. Is this a very unsafe build, or is there a reason that it is actually safe, when text books say otherwise?

I'm planning to build one for camping to use my CPAP machine, do you have any schematic drawing of connection, or maybe you could draw it in Tinkercad (that will be awesome). Great video, you don't need to care about the video length, it is was we are expecting. Great Job!!! This is a small project for a Rocket launcher controller that I made with my son

My question will show my ignorance but if one battery starts to fail don't all the rest reduce output to that same level?

that's real nice, if you had a portable unfolding solar panel you could take it camping and so forth, put it in your RV and have a roof panel, run a swimming pool heater and pump whatever.. how long those cells last?

I am replicating your build! Thank you for such an informative video!
My BMS may be defective... I have the Daly 14s 48V BMS 60a discharge common port. Same as yours....
I built my 2 packs and terminated them and my bms the same way you did. I have about 50VDC before my BMS, but with BMS attached I only see 27VDC.

Just love your project. However there is one question, at 3.5kWh it will take about 500W of solar panel 8 hours to charge it. So for those who is thinking about using it for camping, you need to think about how you are going to connect 5x100 panels. I will be interested to know the max charge Amp. Don't get me wrong this is an amazing generator. The word Solar generator is a very misleading terminology, you need to think about how long and how big a solar panel is needed.
