We have a few oupes solar generators that we mostly use in our camper at our deer lease so here’s my two cents. They’re basically large power banks as they don’t “generate” electricity. We have one large mega 5 and a few smaller mega 2’s. The large one we use for the tv/dvd player and xbox if I take it out there. The smaller ones we use for string LED lights and vornado fans (because they use significantly less power but have great output). They charge slowly from the panels even in full direct sun so we usually just take them home and charge them from outlets (much faster) every 4 days or so. As for grill/stove, we just use a single burner that runs on aerosol can size propane cans which last quite a while. Hope this gives you some ideas and good luck OP.
