Briggs & Stratton PowerProtect 22 kW Dual Fuel (Liquid Propane/Natural Gas) Home Standby Generator 200-Amp Automatic Transfer Switch Included, Symphony Choice Power Management

Among the latest additions to Briggs & Stratton’s lineup, the PP22 home standby generator is part of the acclaimed PowerProtect series — built for dependable whole-house backup power in any climate. Thanks to its low-THD alternator (˂5% total harmonic distortion), it delivers utility-grade electricity for sensitive electronics while its dual-fuel design keeps the lights on whether you’re connected to natural-gas service or a liquid-propane tank.

With 22,000 running watts and 22,000 starting watts, the PP22 can handle two central-air units, well pumps, kitchen appliances and more — automatically — through the included 200-amp transfer switch and Symphony® Choice power-management system.

Power for every essential

With its 45 kVA motor-starting capability, the PP22 tackles refrigerators, sump pumps, well pumps, freezers and 5-ton HVAC compressors without tripping breakers. The integrated Symphony® Choice modules prioritize large loads so your most important circuits stay energized during peak demand.

Fuel-flexible performance & endless runtime

Whether you pipe in natural gas or hook up a bulk propane tank, the precision-tuned Vanguard™ V-twin engine squeezes maximum energy from every cubic foot of fuel — providing days of runtime during extended outages.

Whisper-quiet operation

At just 68 dB(A) measured at 7 m, the generator keeps neighborhood noise to a minimum. A two-stage muffler, optimized air-intake baffles and sound-dampening insulation work together for peaceful performance.

Clean, stable power for electronics

The PowerProtect alternator’s electronic voltage regulator maintains a pure sine wave under 5% THD, so laptops, routers, home-automation hubs and medical devices stay safe from voltage spikes.

Durability & safety you can trust

A powder-coated aluminum enclosure, cast-iron sleeved cylinders and integral vibration isolation withstand years of harsh weather. Protective features include automatic low-oil and high-temperature shutoffs, as well as SAE-class frequency regulation for rock-solid output.

Intuitive controls & remote monitoring

The illuminated LED controller displays voltage, frequency, session runtime and diagnostic codes. Add the InfoHub™ module for cloud-based monitoring — view load, maintenance reminders and alert history from any smartphone.
