What size backup do you actually need?
Don't overpay for a generator you don't need — or under-size one that can't run your fridge and furnace. Pick your must-run loads and see it both ways: a Generac generator or Tesla Powerwalls.
What do you want to keep running in an outage?
Running total: 1,600 W · estimated peak with motor start-up: 3,100 W

Generator or battery — which is right for you?
A generator runs indefinitely on fuel; a Powerwall is silent, fuel-free and recharges from solar (and may qualify for SGIP). A licensed C-10 sizes either around your real must-run circuits.
