About Generator Backup Power

From automatic standby generators that kick on within seconds of an outage to portable units for flexible power, we carry every type and size. Shop trusted brands including Generac, Kohler, Briggs & Stratton, Champion, Cummins, DuroMax, and more.

Generator Backup Options

  • Standby generators – permanent, automatic, whole-home (10kW-60kW)
  • Portable generators – movable power for any location
  • Inverter generators – quiet, clean power for electronics
  • Transfer switches – ATS for standby, manual for portable
  • Generator accessories – maintenance kits, covers, cords
  • Natural gas, propane, and gasoline fuel options

A standby generator with an automatic transfer switch provides hands-free backup—you may not even notice the power went out. For homes already on solar, a generator adds redundancy for extended cloudy periods. Our team helps you size the right generator for your critical loads and fuel availability.
