Yeah, a whole house genset is on my list. I have a small one, but it can't run my heat pump; it's mostly just used to keep my servers and fridge running.
I live near a few important things and am on the same part of the grid as them, so unless it's a very local outage (basically on my street), then it usually gets fixed pretty quickly because the important things are also down. So that's kind-of kept me from really making a generator a priority.
