About Standby Generators — Whole-Home, Estate & Commercial Backup Power
Shop standby generators at PES Supply for permanent, automatic backup power. Our standby generators from Generac, Cummins, and Briggs & Stratton run on natural gas or propane, start automatically during outages, and provide whole-home or commercial backup power from 10kW to 60kW+.
Unlike portable generators, standby units are permanently installed outside your home, connected to your electrical panel via an automatic transfer switch, and require no manual setup or fueling. Most models include Wi-Fi monitoring via Mobile Link for remote status and maintenance alerts. PES Global Group offers competitive pricing, fast shipping from our Louisville, KY operations, expert technical support from our product team, and bulk pallet ordering for contractors and EPCs.
Use our Generator Sizing Calculator (kW to Amps) to determine the right standby generator size for your home's electrical load, or call our team for expert sizing and installation guidance.
