I use a DIY 400-watt solar panel, with 200Ah lipo batteries for backup. I maintain a set of low consumption air pump, circulation pump for rainy day usage. Those pumps can also be hooked up to various portable chargers (mobile power bank, off-the-shelf solar power bank, normal batteries, power tool [ryobi] batteries etc). I have multiple layers of external monitoring (adafruit.io, google wifi, shelly/kasa cloud) to inform and verify power outage when I'm not home. Like earthquake drills, I have trained my family (wife and 6-year-old kid) how to do a basic gear shift (hooking up solar inverter outlet with key equipment) in case of emergency. All my gears are labeled for such operations (color-coded).
This is a major concern of mine (power outage) and I try to get a defense in depth like strategy in place,
