Description

The Champion Power Equipment 100177 8.5-kW Home Standby Generator with an ATS50 Outdoor-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 ATS50 automatic transfer switch operates a 50 amp, 12 circuit load (8 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 3R rated enclosure for outdoor use.

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 439cc OHV engine provides 8.5-kilowatts of continuous power on propane and 7.5-kilowatts on natural gas. This 8.5-kW-rated unit produces 35.4 amps at 240 volts on propane and 31.3 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 59.5 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 ATS50 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.
