Thanks- these links are helpful. A system without a battery sounds more viable than I had considered, but I’m not sure how well it’d work for my intended loads. Maybe I could rethink what I want to run on solar, but I think it’s maybe not really an practical option in my setup where the only two loads I have in mind (probably?) require steady power and wouldn’t do well with momentary dropouts caused by cloud cover. Good to keep in mind though.

When you say “switch to grid power after it runs out,” this is something I was hoping the kit would do automatically for me so I don’t have to flip a switch or change plugs from the solar outlet to the grid outlet. If the kit doesn’t support that, I wondered if something like this ATS would get me what I want. I’d wonder how exactly it decides to switch back and forth though (it switches to the backup automatically, but will it switch back to primary on its own, and if so, under what conditions? Will it constantly switch back and forth or is there any sort of hysteresis? etc).
