A power station does not back up a house. It backs up a handful of circuits for a number of hours — and that number is calculable from a measurement rather than guessed from a rating.
Start with the best power stations for home backup for the ranking, or running a fridge through an outage if refrigeration is the thing you actually care about. If you are weighing a battery against an engine, generator vs battery covers fuel, noise, permits and ten-year cost.
One warning that applies to everything in this section: connecting any battery to your home's wiring is licensed electrical work in most US jurisdictions. Nothing here is installation guidance.
