I'm living/working remotely off grid with a solar panels, batteries, and a 2000w inverter. It's comfortable. I usually have a few lights, the wifi router, a monitor, laptop charger, and a fridge plugged in. This comes out between 100w and 300w, so I have room to spare for bigger items like power tools.

I do cheat by using a propane range for cooking and wood for heat. At some point I'd like to move to an electric induction stove, but I need to do some research how efficient they are.
