I cannot attest to either personally, but Jackery and EcoFlow are recommendations I have received recently.

nostr:npub1njrdwafh5cuqecm3uwjgvz78u8aj4kajsgdlr283e48gecpzgrysmg2mct has some experience with this I think!

There's others as well, try looking for #solar or #solarpunk

I found you growNostr and gave you a follow

If you're looking for a budget system look for Steven Harris on The Survival Podcast with nostr:npub15879mltlln6k8jy32k6xvagmtqx3zhsndchcey8gjyectwldk88sq5kv0n. It's a very old podcast but all the basic info is there for a house or vehicle system. Mine is a mess (my next project it cleaning it up and building a cabinet) but it has enough power to run our necessities for 24 hours.
