Prana jeans might fit the bill. Their Carlsbad straight leg is pretty good. You’d have to check the sizes. I’ve had some jeans for 8+ years from them.

I don’t know what might be best, but I’m curious myself. So I hope someone can help.

I have been doing some reading, and it seems like you’d be giving up a bit of functionality with not having a smart BMS with that victron piece.

For a future-proof, safer, and smarter setup, upgrading to a CANBus- or RS485-enabled BMS that speaks Modbus or Victron CAN protocol is highly recommended. It makes system integration smoother and battery life longer.

I don’t know which one would be best though. Maybe something like this? https://overkillsolar.com/

Sounds like you’re well on your way. Mine still has some issues so I’d love to stay in the loop on your build a d will offer any help I can.

That’s a good point about the multiple batteries, I guess I hadn’t considered that.

I was able to get mine to run a chest freezer over the summer, but once the sun shifts to fall it isn’t able to charge back up fast enough. I’ve only got two panels and they are on the wrong side of the roof. Also we had a power outage last year during a snowstorm. I was able to plug my house fridge/freezer into my system and it kept our food from going bad. Running a few cpaps should be simple.

There are a lot of uses for a small offgrid solar battery system

This won’t work for most tool chargers as they are 110-240v usually.

I have built this, it’s not perfect and I made mine a little over kill. I even have an extra inverter because I tried to scale mine up to charge a Nissan leaf. It successfully did so, but only for a few minutes before it would get too hot

What questions did you have?

As for advice, buy the correct crimping tools, a good set of wire cutters and be sure to get the correct sized wire. I’d also suggest pairing it with a battery, I just did a 12v marine battery lifepo chemistry and made sure my charge controller can handle it. This was actually kinda necessary because it keeps an even charge.

I didn’t use any calculators or spreadsheet, except the one that showed what the nominal voltages were for my battery

Also I’d say I regret doing one large instead of multiple smaller batteries just because of cost.

I’d be happy to help more but just know I am not an expert, or even that skilled at electric work.
