The Champion Power Equipment 100176 12.5-kW Home Standby Generator with an ATS100 Indoor-Rated Automatic Transfer Switch 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.
An all-weather, composite mounting pad is included for easy installation, plus the steel enclosure protects your generator from the elements. The ATS100 automatic transfer switch operates a 100 amp, 16 circuit load (12 space sub panel allows up to 4 tandem breakers). It is ideal for homeowners who want to power emergency essentials during a power outage as opposed to the whole house. It is housed in a NEMA 1 rated enclosure for indoor use (not recommended for CA installation, see model #100179).
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 ATS100 is UL and cUL listed in the US and Canada. 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.
