Champion aXis 22 kW generator features aXis Controller™ with 4-inch color display and Power Line Carrier technology, which uses your home’s existing wiring so your generator can talk to the automatic transfer switch and other components without needing to run separate wires, saving you money and time on installation.

With aXis Wi-Fi Direct your installer can use a tablet or cell phone to program your generator meaning less hassle, faster setup, and lower cost.

The Whole House automatic transfer switch backs up your home’s 200-amp distribution panel and has the ability to manage your high-demand appliances by using our aXis Load Management Modules model 100868 (sold separately). Featuring a NEMA 3R Service Entry rated enclosure, this switch may be installed indoors or outdoors and is ETL listed to comply with UL standards for the US.

The innovative advanced airflow design stands out from the competition and allows your HSB to operate at cooler temperatures which extends the life of your engine. Your HSB is up to 20% more fuel efficient than leading competitors with 3.6 gal/hr using propane and 270.2 ft3/hr using natural gas at rated load.

Be confident your HSB will hold up to any weather thanks to the aluminum-zinc coated steel enclosure, offering better structural rigidity with the oxidation resistance of an all-aluminum enclosure, plus the gullwing opening allows for easy service and maintenance access.

The starting system operates in temperatures ranging from -22° F to 104° F, never needs refueling operating on your home’s NG or LP fuel supply, starts automatically when the power goes out, and returns to standby when power is restored.

The 999cc V-Twin Champion engine provides 22-kilowatts of continuous power on propane and 19.8-kilowatts on natural gas. This 22 kW-rated unit produces 91.7 amps at 240 volts on propane and 82.5 amps at 240 volts on natural gas.

The residential-friendly 67 dBA is a little louder than normal conversation.

The alternator produces less than 5% total harmonic distortion (THD) to ensure safe use with even the most sensitive electronics.

This generator is available for all 50 states. Buy with confidence - Champion Support will back your purchase with FREE lifetime technical support, a 10-year limited warranty on the generator and a 2-year limited warranty on the ATS.
