If you live in a place where power outage are often, you should reconsider which type of nodes are you running. A public node (that have to stay 24/7/365 online) is not meant to run in such bad environment. You are doing more harm than good to the whole network with that.

Run instead private nodes, that doesn't have to be 24/7 online and are perfectly fine. https://darthcoin.substack.com/p/private-lightning-nodes
