At home I have a 600va UPS that protects my cable modem, RPI router, and POE switch which serves 2 APs. That lasts about 30 minutes, which gives me enough time to fire up my generator.I'd assume it doesn't take you that long to fire up the genie, if you are home when the power goes out :-).
If it's just a little gasoline generator, 30 minutes is about right. It takes 10 minutes to decide the power isn't coming back soon and another 10 to drag the generator out of the shed, hook up the wires and get it going even though it's cold, wet, and hasn't been run for several months. That leaves 10 minutes to spare figuring out how to convince the UPS that the generator power is good enough to retransfer and stay. Regards, Bill Herrin -- For hire. https://bill.herrin.us/resume/
