Product Overview

The Champion Power Equipment 100174 8.5-kW Home Standby Generator with an ATS50 Indoor-Rated Automatic Transfer Switch is The Simple Solution to a power outage. The generator starts automatically when the power goes out and returns to standby when power is restored. 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. The ATS50 automatic transfer switch operates a 50 Amp, 12 circuit load (8 space sub panel allows up to 4 tandem breakers). It is housed in a NEMA 1 rated enclosure for indoor use (indoor switch not recommended for CA installation, see model #100177). 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. It produces 35.4 Amp at 240-Volt on propane and 31.3 Amp at 240-Volt on natural gas. 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. 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.
