I know there's a lot of these builds like this out there, but I'm surprised at how well this turned out. It was a good excuse to try working with new materials, tools, and components. Primary goal for this was to build something compact that I could take with me camping so I'd have power to run...

Here's a list of all the major components I used (aside from the wires, terminals, screws, etc.). Total ended up being $631. Definitely could have cut some corners and got cheaper stuff or reduced the number of ports, but decided I'd rather do it (mostly) right the first time. Component...

Thought I’d post a quick update: Done a few cycles and haven’t had any issues. The built in solar charger works great. I can go from 0-100% charge in about 7 hours with the 250W panel I’ve been testing it with (outputs close to 210W). In all my testing, with the lid closed, the internal temp...

Thanks! Got a 2 pack from Amazon: https://a.co/d/f79FIND

Haha, yes. There were a couple of those needed for this build. It took me a few tries to get the technique down.

Been doing a lot of reading and watching DIY videos and I'm getting around to the planning phase of what I want to install in my vehicle. I've attached a wiring diagram for what I'm thinking. This will primarily be used for off-grid camping, mostly for charging devices as well as powering a 12V...

Makes sense. With the compressor, I'll only be using it to air up the vehicle's tires, so it's run time will be intentional. Regardless, I made a few revisions to the original diagram to help mitigate some of the issues you've brought up. Added a 5 pin automotive relay on the starter battery...

Thanks for taking a look! To provide some clarifications to your questions... The starter and house batteries will never be connected directly. The house battery is charged through the DC-DC charger. The power source switch was intended to select which battery should power the onboard loads...

Okay, so I did some readying on battery isolators and what it's describing is accomplished through the DC-DC charger I designed into my system. The input wire comes from the starter battery, output wire goes to the house battery. Unless I'm missing something, I don't see the need for a dedicated...

Thanks, I'll definitely do some digging on battery isolators. This setup is for the vehicle. The 120A connector at the rear could be used for connecting a trailer's separate battery charger (positioned closer to the trailer's batteries). The house battery will never be used for powering the...
