Champion 8.5 kW Air-Cooled Home Standby Generator with 50A ATS

The Champion Power Equipment 8.5 kW Home Standby Generator delivers always-on backup for the essentials — refrigerator, freezer, well pump, sump pump, lights, internet and a select set of outlets — without forcing you to babysit a portable unit during a storm. The system auto-detects utility outages and brings the home back online within seconds, then transfers cleanly back to grid power once it is restored.

Output is 8.5 kW running on liquid propane and 7.5 kW on natural gas, so you can pick the fuel that matches your home’s setup. The bundled 50 A NEMA 3R outdoor-rated automatic transfer switch handles up to 10 essential circuits, more than enough to keep food cold, the basement dry and the family connected during a multi-day outage.

Champion’s air-cooled OHV V-twin engine is paired with full-pressure lubrication and a corrosion-resistant aluminum enclosure, so the unit holds up to coastal and high-humidity climates. A built-in cold-weather kit and quiet test mode at low RPM round out a generator engineered to be installed and forgotten.

Backed by a 10-year limited warranty and Champion’s nationwide service network, this is a strong value choice for homeowners stepping up from portables to a permanent backup solution.
