Briggs & Stratton PowerProtect 18 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 PowerProtect PP18 home standby generator is part of the acclaimed PowerProtect series — engineered for dependable whole-house backup power. Driven by a commercial-grade Vanguard™ V-twin engine and paired with a 200-amp automatic transfer switch, it springs to life within seconds of an outage and keeps every circuit in your home energized.

Delivering 18 kW of continuous output on both liquid propane and natural gas, the PP18 easily starts central air-conditioning systems, well pumps, water heaters, and other heavy-demand appliances. Dual-fuel flexibility lets you choose the most convenient energy source, while Symphony Choice™ power-management technology prioritizes high-starting loads so lights never flicker and breakers never trip.

Power for every essential

With a 45 kVA motor-starting capability, the PP18 tackles 5-ton HVAC compressors, sump pumps, refrigerators, and well pumps without breaking a sweat. Symphony Choice™ automatically sequences large appliance loads to prevent overloads and maximizes generator capacity.

Fuel-efficient performance & extended runtime

Precision EFI and a high-efficiency alternator squeeze maximum energy from every cubic foot of gas. At half load, the PP18 consumes just 176 ft³/hr of natural gas or 2.2 gal /hr of propane — keeping fuel costs in check during multi-day outages.

Whisper-quiet operation

A sound-attenuated enclosure, low-idle mode, and oversized muffler keep operating noise down to 68 dB(A) — neighborhood-friendly and compliant with most HOA requirements.

Clean, stable power for electronics

The synchronous, electronically regulated alternator maintains voltage within ±1% and Total Harmonic Distortion below 5%, protecting laptops, smart-home hubs, and medical devices from damaging surges.

Durability & safety you can trust

A corrosion-resistant aluminum enclosure, cast-iron cylinder sleeves, and full-pressure lubrication ensure years of reliable service. Safety systems include low-oil shutdown, high-temperature shutdown, and sealed electrical connectors for harsh-weather protection.

Intuitive controls & optional remote monitoring

The illuminated GC-1032 control panel displays voltage, frequency, engine hours, and diagnostic fault codes. Add the InfoHub™ cellular gateway (sold separately) to view real-time status, maintenance alerts, and run history from iOS or Android devices.
