Standby Generators for Automatic Backup Power
Protect your home or business with an automatic standby generator from PES Supply. Unlike portable units, standby generators are permanently installed and kick on automatically within seconds of an outage—keeping your lights, HVAC, refrigeration, and critical systems running. Shop top brands including Generac, Kohler, Briggs & Stratton, Cummins, and more.
Choose Your Power Level
- 10kW to 26kW residential standby generators for whole-home coverage
- 30kW to 60kW commercial and light-industrial units
- Air-cooled and liquid-cooled options
- Natural gas and LP fuel options
- ATS-compatible for seamless transfer
Standby generators run on your home's natural gas or propane supply, so there's no fuel storage or refueling required. With professional installation, a Generac or Kohler standby unit can power your entire home for days or weeks during extended outages. Browse our selection by wattage to find the right size for your needs.
