We lived off grid in the bush here in Australia on Northern NSW for a decade with a 2kW solar system and batteries, never had an issue, ran everything (computer, kettle, microwave, welder, induction cooktop etc) except for the oven. We left in 2020 because of climate chanhe making bushfires worse and have now moved to Tasmania, off a flood plain, 270m ASL, and zero bush fire risk.

We now have a small cottage on a hectare, on the edge of small village, we have 8kW solar here (so far south solar in winter is an issue) , the excess goes into the grid for which we are paid a small amount and we now have an ecar we need for very occasioanl use (mostly use our ebikes amd walk) , all charged off solar.
