Picking the Right Generator

Home standby units from 10 to 26 kW start automatically within seconds of an outage and run on natural gas or propane — no refueling, no extension cords. Portable and inverter generators cover job sites, RVs, and occasional outages; inverter models produce clean power that is safe for electronics. Size standby units from your essential circuits: a 22 kW air-cooled unit covers most homes, including a 4-ton AC with load management.

Pro Tips

  • Standby means automatic, NG or propane, whole-home
  • Inverter generators for clean power and quiet RV use
  • Pair every standby with an automatic transfer switch
