    The Champion Power Equipment 100362 12.5-kW Home Standby Generator with a Milbank ATS200 Whole House Service Entry Rated Automatic Transfer Switch with Demand Control is The Simple Solution™ to a power outage. Enjoy peace of mind while ensuring security and convenience for your family during an emergency.

    The generator starts automatically when the power goes out and returns to standby when power is restored. The 24-volt starting system operates in temperatures ranging from -22° F to 104° F with no warming kit necessary.

    You’ll have the starting power you need during an emergency since the onboard battery charger maintains the charge at all times, plus, since the generator is connected to your propane or natural gas system, it never needs refueling. This unit also performs weekly self-diagnostic tests.

    With a Milbank Whole House switch, your home’s power requirements are monitored continuously. This ATS can back up your home’s entire distribution panel with the ability to manage up to 4 high demand appliances and 2 air conditioners for your Whole House power needs. Your home’s circuits are divided into prioritized zones – from vital to managed. If your generator nears maximum capacity, pre-designated, high demand appliances are managed to avoid overload. As soon as demand lowers, the generator will automatically reacquire the appliances that are managed. Appliances are managed and reacquired individually. Switches are also available in 100 and 150-Amp option.

    An all-weather, composite mounting pad is included for easy installation, plus the steel enclosure protects your generator from the elements. Our innovative gull-wing design provides easy access to the engine and control panel and allows a full view of the onboard control system.

    The Champion 717cc OHV engine provides 12.5-kilowatts of continuous power on propane and 11-kilowatts on natural gas. This 12.5-kW-rated unit produces 52.1 amps at 240 volts on propane and 45.8 amps at 240 volts on natural gas.

    The sound-dampening lining and low-tone muffler reduce noise through a unique baffle system and make this unit the quietest in its class. The residential-friendly 63 dBA has about the same noise level as 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, and the ATS200 is UL listed in the US. Buy with confidence - Champion Support and our nationwide network of service centers will back your purchase up with a 10-year limited warranty and FREE lifetime technical support.
