In my corner of Europe, I have vacationed in a house that’s completely off-grid with solar and a bit over 20 kWh of storage (it does use about half a ton of wood pellets for heating during the coldest months of winter). Link in Czech: https://www.csdum.cz/jak-jsme-postavili-cesky-sobestacny-dum...

I wonder how it would fare with just 100 kWh of storage, something you can still easily put together.
