Best Home Standby Generators

Permanently installed, running on natural gas or propane, a standby generator detects an outage and restores power in about 10 seconds — whether you're home or not. It's the only option that protects sump pumps, freezers, and HVAC while you're away. Budget for professional installation: the unit is roughly half the total project cost.
