Switching the whole house is cheap compared to the generator or battery needed to run everything in the house. Of you can't run everything then you may as well have nothing. The important things need a lot of power.

Who says? Say I need my fridge, freezer, router and a light or two. That's $4k. Whole house? $25-35k.

Also, I have a wood burning stove and piles of firewood).
