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
Generators — Frequently Asked Questions
What size standby generator does my home need?
A 22–26kW air-cooled unit covers most homes including a 4-ton AC with load management. We size from your essential circuits and service panel — send us your loads for a free sizing.
Standby or portable?
Standby starts automatically within seconds of an outage and runs on natural gas or propane — no refueling, no cords. Portables cost less up front but need manual setup and gasoline storage.
Do I need a transfer switch?
Yes — every standby unit pairs with an automatic transfer switch, and portables need a manual transfer switch or interlock. Never backfeed a panel through a dryer outlet; it is lethal to line workers.
Can a generator back up a solar home?
Absolutely. Generators pair with battery systems for extended outages — the generator recharges the battery bank so it runs a fraction of the time. Ask about generator-support settings on Sol-Ark and Schneider hybrids.
