Home Battery Backup Power Vs. Generators | EnergySage
Many standby generator options in the $2,000 to $7,000 range can power a standard American home. But the average generator cost, including installation, is $9,000. By comparison, a 10 kilowatt-hour (kWh) home backup battery costs about $8,000 after incentives. If you want whole-home power, you''ll probably need more storage than that, though.
