Thanks for the good info and link. I'll stick with gasoline. Interesting how much propane it takes to run the generators, I had no idea.

2KW is small for a house & transfer switch but I'm just trying to keep the refrigerator and maybe a few lights going. Nothing in our house is 240V.

We're fortunate to have a robust power grid so I'm not envisioning an outage for any long duration (excluding a large earthquake - then all bets are off).

I haven't done much research yet but I'm leaning towards something like this for a x-switch:
