20k should power your nextdoor neighbors house too.... We've been thinking about getting a propane gen that flips on automatically....something along 10k but the cost..... The one we have now is a pull cord and it's really there to keep the animals in water, us from freezing or overheating and able to cook and see etc. Weve gone several days w/out power as well. There's enough extra power to do all three fishtanks, run the pump and 150 watt light for the plants so.....

I blelieve X-C told me he's got that setup.....propane hooked up directly and turns on automatically....might ask him for that info.
