Generac

Generac's air-cooled Guardian line covers the residential ladder: 10-14kW for essentials circuits or smaller homes, 18-22kW for most of a typical house including one AC, and 24-26kW for true whole-home coverage on 200A service. Liquid-cooled Protector models take over from there for large homes and light commercial. Send us your square footage and major appliances and we'll size it.

Guardian is the air-cooled residential line (10-26kW) — automotive-style engines, aluminum enclosures, and the volume leader in home standby. Protector is the liquid-cooled line (20-60kW+) with commercial-grade engines for large homes, estates, and businesses that need longer runtimes and three-phase options. If your load calc lands under 26kW, Guardian is the answer.

Every Guardian and Protector unit is field-convertible between natural gas and LP. Natural gas is the default when a meter exists — unlimited runtime, no tanks. Propane serves rural properties: size the tank for at least 3-5 days of runtime (a 500-gallon tank is the common minimum for a 20kW+ unit). Output ratings are slightly lower on LP — check the spec sheet.

The unit self-tests weekly on its own schedule. Owner maintenance is oil and filter changes (every 200 hours or 2 years on air-cooled models), air filter, spark plugs, and keeping the enclosure clear. Generac's Mobile Link Wi-Fi monitoring reports status and alerts to your phone. Cold-climate installs should add the cold-weather kit — battery warmer and oil warmer.

Yes — an electrical permit for the generator and transfer switch, a gas permit for the fuel line, and setback compliance with your local zoning. The install is licensed-electrician plus gas-fitter work, typically 1-2 days plus inspection. Generac's warranty and most utilities require permitted installation.

Guardian units ship freight on a pallet, curbside, 450-600 lbs depending on size — plan equipment or a crew to move it to the pad; liftgate delivery is available. Portable Generac models ship parcel or LTL by weight. Inspect the crate at delivery and note damage on the freight receipt before signing.
