Ever look into a whole home automatic backup generator? We have had them installed in our last 2 homes. The one in Louisiana more than paid for itself when we lost power for 48+ hours in August a couple times. In Tennessee, the main reason we installed one was because we were 1 or 2 houses on a supply line so at the bottom of any repair list if a major outage/disaster. Longest outage has been 8 hours here.
We did that after the long outage. Worked like a charm. Not a single power outage for the remaining years we lived in that house. We’re contemplating adding battery backup to our solar panels right now.
