This is something I've been thinking about recently due to a potential new policy from PG&E (Northern California electric utility) in which they would preemptively shut down electricity to high fire risk areas when red flag conditions are present. I live in the Oakland hills which would be affected by that plan. PG&E says they expect such an outage would occur 2-3 times per year in October/November, and that because they have to do a lot of safety checks before restoring power, that we should expect those outages to last 3-5 days.
So 3-5 day outages 2-3 times a year sounds like a right pain the ass, and certainly has me looking at adding a powerwall to our PV system. I had wanted one anyway for backup in the event of an earthquake or other event that might disrupt power for an extended time, but now we're almost guaranteed those outage events, rather than it being a hypothetical.
