Gas water heater, no well pump, no sump pump, gas furnace.
Even 220 Volt equipment COULD be powered from a battery bank and inverter - 110 is typically just a center tapped 220 anyway.
In the night I only need a light or two, maybe the furnace blower.
The fridge and chest freezer could wait until daytime when I'm willing to fire up a little rat-a-tat-tat generator.
What I like most about the inverter idea is that I could get fairly fast switching, (supposedly 16.6 milliseconds, 1 cycle) to avoid brown downs.
The power company cares only that I have break before make.
I should add that this house has had ONE power failure in the last 35 years that lasted almost 15 hours, perhaps 4 others that went 12 hours.
For whatever reason(s) the level of service has been very good, so I don't think I need to plan for the ultimate paranoid triple worst case scenario.
