About product

The newest member of Briggs & Stratton’s residential lineup, the PowerProtect PP18 home standby generator delivers dependable whole-house backup power. Engineered for permanent installation outside your home, its low-THD synchronous alternator keeps electricity stable for sensitive electronics while the rugged Vanguard® V-twin engine provides automatic, hassle-free performance during any outage.

Rated at 18 kW continuous output on either liquid propane or natural gas, the PP18 can start large 5-ton air-conditioners, run well pumps, refrigerators, medical devices, and charge EVs without breaking a sweat. Because it connects directly to your home’s LP/NG supply, runtime is virtually unlimited — no messy refueling or drained gas cans to worry about.

  • 18 kW continuous standby power (LP/NG)
  • Dual-Fuel – hooks to existing LP/NG line for unlimited runtime
  • <5% Total Harmonic Distortion – safe for laptops & smart-home hubs
  • 68 dB(A) normal • 64 dB(A) low-idle (quieter than most central A/C units)
  • Hard-wired 120/240 V output through 80-A generator breaker (ATS sold separately)
  • Automatic start & GC-1032 digital controller
  • Aluminum enclosure resists corrosion and is wind-tested to 186 mph
  • Comprehensive safety shutdowns: low-oil, high-temp, over-speed, & over-crank
  • UL & cUL listed • NFPA 37 18″ installation clearance
  • 7-year parts, labor & travel warranty (7 yr / 1000 hr commercial)

Whole-house muscle for every essential

With its 45 kVA motor-starting capability, the PP18 easily handles heavy-duty loads like 3-stage heat pumps, electric ranges, and shop compressors without dimming lights or tripping breakers. Intelligent load management (optional ATS) automatically prioritizes high-draw appliances to keep your family comfortable.

Continuous runtime — no refueling required

Connected to your home’s propane tank or natural-gas meter, the Vanguard engine sips as little as 99 ft³/hr of NG at no-load, yet ramps up instantly when demand spikes. That means days — or even weeks — of uninterrupted power during extended blackouts.

Whisper-quiet operation

The sound-attenuated aluminum enclosure, oversized muffler, and low-idle mode keep operating noise at a neighbor-friendly 64–68 dB(A) — quieter than a typical conversation at the property line.

Clean, stable power for electronics

The brush-type alternator with electronic voltage regulation maintains <5% THD across the load range, protecting today’s sensitive electronics from harmful voltage spikes and waveform distortion.

Built to last — rain or shine

A full-pressure lubrication system, cast-iron cylinder sleeves, and integrated vibration isolation extend engine life, while the marine-grade aluminum housing shrugs off rust, salt-spray, and extreme weather.

Intuitive controls & remote monitoring

The back-lit GC-1032 controller displays voltage, frequency, and service codes at a glance. Add InfoHub™ Universal accessory and check generator status, fuel usage, and maintenance intervals from your smartphone — anywhere you have a signal.
