We’ve had a string of winter storms (3 in two weeks and a 4th on the way), and in each storm we have lost power, the last one for a little over a day. When we have a power failure, I wait about 30 minutes then isolate from the grid, and power up most of the house with a Honda EU2000i generator.
I put the generator on our back deck and cover it with a small table, but that often isn’t enough to keep the snow off of it. Doesn’t seem to matter. The only significant loads are the heating system and refrigerator. We used less than a tank of gas to keep things running for the last event. Good thing is it is RF quiet. Even better thing is I can’t hear it running (but can hear other generators all over the neighborhood ).
