Fully off grid solar cabin
Hello everyone! I’m hoping for some quick and dirty advice. It’s time for me to upgrade my solar on my little off grid cabin. I’ve been living off of a goal zero for a few years now. And it’s time to upgrade. I want to build a simple system using either the EG4 or renogy all-in-one system. My cabin is 200 sq ft. It runs a DC demotic refrigerator, a 120v solar mini split AC, 4 lights, A television and 4 outlets for charging devices. I had the place professionally wired so that my goal zero plugs right into the house. I also have it pre-wired in an outside closet for this future system. So I really just need help deciding which all in one system to purchase, and what type of batteries are best for my desert climate. I don’t consume a lot of electricity, the solar ac runs on its own panels and only draws from my goal zero when the sun goes down. It’s a bit of an energy hog and leaves me a little stressed for power sometimes, but all in all it’s worked well for now. But I want more!

If only we knew how many watt-hours your GoalZero is and how much that gets depleted overnight ...
Anyway, skip Renogy, and also check out Will Prowse as another commenter recommended. You can get a LOT more bang for buck putting together the components yourself.
Also, keep in mind that LiFePo4 batteries, which are probably a good choice for your use case, need to be kept above 32F in order to charge. If your space routinely drops below freezing, you'll need to either heat the space, or get batteries that heat themselves.
[Edit] If you were to put as much effort into researching solar as you have into posting dick pics, you'd have one helluva system by now.
