Hey Peter,
I’m not sure about whether you’d be able to have the Pi auto-reboot when the power is cut then restored, although if you take a look at the two forums below, you may be able to set up an auto reboot every so often and use one of the battery pack hats to keep the Pi running through outages.

Have a great day!
