Solar Generator – Finished Version and Final Design Updates

Solar Generator - Finished Version and Final Design Updates

The finished large solar generator featured in our "DIY How To Build a Solar Generator" video series. We go over the solar generator features, solar panel kit specs, and battery bank expansion units. In addition, we show how to upgrade / improve several aspects of the original design including a higher power AC power inverter (3,000 watt continuous, 6,000 watt peak), fully waterproof external switches, mounting improvements, and a better way to store accessories inside the solar generator main case.

I have posted links to the updated components I am using below. See the full component list and build instructions here:

    Great job. I have a 5000-10,000 watt unit mounted in my pick up truck box built based on you design and build. I have a few tweaks to make to it now but I love the versatility of the high amp plugs and 12 volt outlets.
    I would proudly sport one of your stickers.

    Hi really great job, thanks a lot. You encouraged me to do the same portable box but with small edition, my question is,, Can it be charged through cigarette lighter in the car?

    Great video, very informative and i will definitely use it for my design.  I'd also love a sticker…Thanks, Andrew

    Very concise vids Thanks.. IF you still have a sticker Ill sport one. Getting 4 more 6 volt golf cart batteries for my 2nd solar project tomorrow..whoop whoop!

    Good update. But I want to add a second trap case for 2 , 3, or 4 more batters to extend my battery time as I'm running full sized freg. Can you make a video on wiring that please and adding a port to the main trap case?

    I just completed my build. Inverters are hard to find right now, called Krieger and found that the 3000 is on back order for an undetermined period of time, so I went with a 4000 watt Krieger, so we are now the proud owners of a 4000 watt solar generator based on your build. Thank you so much for the time you invested and for sharing your knowledge. Hubby and I love to boondock but are not ready to lay out the money for a full solar build on our RV. The most we do is charge our phones, iPads, occasionally the laptop and use a blender for smoothies, this generator is going to be more than sufficient for our needs. I would proudly sport one of your stickers if you still have one available.

    Liked & Subscribed….Brilliant!   Sticker please…if still available? I've wanted to come up with a working source of power to keep us afloat if/when SHTF….  Thanks for all the hard work….

    By far the best day built unit I have done lots of research and watched hours and hours of video… great job, clean and extremely useful.

    I have watched your videos over and over. You have the clearest and easy to understand instructions on youtube. I had been interested in building one for a while but now I am going to build one over time especially after dealing with Hurricane Harvey here in Corpus Christ, TX. I have already built a solar shed lighting setup with a 10 watt panel, small charge controller, 12v 9ah battery and some led light strips turned on by a toggle switch. Lights up the shed incredibly. I also just bought a dual fuel generator since it was a deal I couldn't pass up on but I am going to build a solar generator to have multiple options. I would love to get some stickers so I will send you a message for some. Also, I noticed that the inverter that you upgraded to isn't on amazon anymore or at least I can't find it. Any suggestions on a comparable model.

    Yeah, Im a fool that likes wasting my $$.  Got two used Battle Born 100aH Lithiums for 1/2 price.  Gonna put these two in a larger Pelican box, add MPPT Solar and 400 W solar panels, 200 to take overloading.   pairing with a Redarc to connect to the Vehicle via the 4Runner 12vTrailer wiring and let it rip!  Who knows, total noob so lets see if it works…awesome video.

    Im just looking into this, and know very little.  My question is your trickle charger for when you plug into A/C.  Why not just use a bigger noco genius charger that charges at higher amps.  I have a noco 26amp ac charger.  Can I just hook this to my internao lithium battle born battery?(used for 250$) …had to go lithium with that deal.

    Really a nice set up you made there.

    Can the battery be charged from a vehicle through the 12vdc outlet? I'm just thinking that if you had it in your vehicle you could run a long cord that plugs into your cigarette lighter outlet and into you box and charge your battery while driving down the road.

    What about adding a retractable 25 foot extension cord reel mounted inside the box and have a single gang outdoor rated electrical box that's weather proof and a spring loaded cover mounted on the outside and have the cords female end store inside that weather proof outdoor rated electrical box. Then when you need an extension cord, just lift the spring loaded cover, reach in and grab the female end and pull out the cord. Now you always have a wired up extension cord that you can just grab and use and rewind it quickly.

    I'm really enjoying you channel and decided to sub. Keep up the great work.

    OK, 3/4 done.  Have my solar working to charge the lithium battery via the Redarc BCDC1225D.  Now what I want it to have a meter that tells me how much of a charge I am getting via my solar panels.  I'd also like another monitor to tell me my load on the battery and its status.  Doing a little more research here….

    Did you ever plan on putting in a monitor?

    I've always been under the impression that invertors over 1500 watts needed at least 2 12v batteries, no matter the Amperage. Is the AC side only utilized when the panels are hooked up?

    Hey, If you have any stickers left I would love one! After checking out solar generators and wanting a Goal Zero generator, I cannot bring myself to spend that kind of money on them. So I have decided to make my own version (your version of it). I have never done this and I am very excited to try this.

    Maybe a simple question but would this run a sm (pop up camper) ac and a small cube deep freeze?

    Love to get a sticker if you have any left. Recent sub (late to the party haha). Love the pelican cases!

    does the pure sinewave inverter overheat if its in a sealed box?
    have you thought about using Headway batteries for the power holders they are lighter

    Do you sell any units, I go camping with my 2 kids with my camper. Single parent have no time or patience to make unit.
    Thanx. Great unit..

    Hi Mark. Can you tell me what size wire clamp (knockout size) to wire the inverter or what to order? My knowledge of electrical wiring is extremely basic!

    Very nice, what was the total cost of the build. I'm definitely going to try and build one similar to yours, for overlanding

    I guess with the light switch you could just not hook up the ground so it does not light up or if you set it up all the time so you can find it in the dark but it being on with the light on doesn't make a lot of sense because it is literally turning on a bright light

    With 3000 watts available you should really hook the GFCI plug wires wrapped around the screw the push in are not rated for as many amps but then again 3000w is what like 25ish amps which that plus is what 15 or 20 amp rated

    I'm also planning to set up a solar power system. However I will not use an inverter. I will instead spurn appliances that operate on AC and replace them with DC-powered systems.

    We want you to know that your videos were the inspiration for us to build our own smaller solar generator last year. It was made from two 6v 400ah batteries and one LG 265w module. We have since scrapped that for a much larger, trailer-mounted generator which is almost complete. This one has 1560 watts of modules and 19,200 watts of total battery power. It has a 12 kw, 48v inverter and is capable of operating a small stick welder (and just about anything else we'll need). We are going to use the generator to build our off-grid home in the Intermountain West. Check out our videos if interested. We just want you to know that your videos were the impetus for all of this. Thank you!! We are subs!
