Been off-grid a few years now on some land in the countryside in Argentina. Small place, solar, well pump, fridge and freezer.

First battery bank I put in was way too small. Figured the sun is strong here so a day and a half would cover me. Winter and a stretch of cloudy days proved me wrong fast. Ended up running the generator a lot and lost some food once when everything died.

Now I’m using around 7-8 kWh a day and running a lithium bank that actually lasts. Gives me a couple solid days without sun before things get tight. Still have a small generator as backup but I almost never need it anymore.

Main thing I learned the hard way: don’t cheap out on storage if your area gets real cloudy stretches. Lithium costs more upfront but you stop replacing batteries every few years.
