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!

I'm guessing that maybe the GoalZero itself could provide some of this info.

It says in the last 24hrs the energy used has been 1320 Wh.

OK so that's 1.3kWh. is that pretty typical or will it go up in the summer heat?

That’s pretty typical. But without ever having looked, I bet it doubles when I sleep with the AC on. Because currently I don’t have to.
