22kW Briggs & Stratton PowerProtect+ Standby Generator - 120/240V, Dual Fuel (LP/NG), Vanguard Engine, 7-Year Warranty - Model 040787

Briggs & Stratton 22kW PowerProtect+ Standby Generator – Maximum Whole-Home Backup Power with the Best Warranty in the Industry The Briggs & Stratton 22kW PowerProtect+ Standby Generator (Model 040787) delivers the ultimate in residential standby protection — engineered for large homes, luxury properties, and households that demand full whole-home coverage without compromise. When the grid fails, this generator detects the outage and restores 120/240V power within seconds, keeping your central air conditioner, heat pump, electric range, refrigerator, freezer, sump pump, lighting, home office, and entertainment systems running exactly as if the power never went out. Powered by the Briggs & Stratton Vanguard® M61 V-twin engine — naturally aspirated, 61 ci / 993 cc, aluminum block with cast iron sleeve, OHV valve arrangement — this generator is built on a commercial-grade engine platform engineered for reliable, continuous standby performance through years of service. With 22kW output on both LP and natural gas, the PP22 is one of the only generators in its class that delivers full rated power on natural gas — no derating, no compromise. Both fuels are fully supported for complete installation flexibility. Exclusive Front-Facing Exhaust Only Briggs & Stratton offers standby generators engineered to direct exhaust away from your home and landscaping. The front-facing exhaust design on the 040787 enables installation as close as 18 inches from your home — approved to NFPA 37 per Southwest Research Institute — giving you more placement flexibility than any competing generator while protecting your home's exterior and landscaping. 45 kVA Motor Starting Power — Best in Class With 45 kVA of motor starting capability, the 040787 handles the largest residential electrical startup loads without hesitation — including a 5-ton central air conditioner, well pump, sump pump, and other motor-driven appliances running simultaneously. This is best-in-class motor starting power for the 22kW residential category, ensuring your most critical systems come online immediately and stay online throughout an extended outage. EnergyTrak™ Integrated Remote Monitoring The built-in EnergyTrak™ app lets you monitor your generator's status from anywhere and enables your dealer to remotely troubleshoot and diagnose issues — reducing service call times and keeping your generator ready at all times. Unlike the optional InfoHub™ on smaller residential units, EnergyTrak is fully integrated into the PowerProtect+ platform. Eco-Cise™ 16-Second Weekly Test Mode The automatic 16-second weekly exercise cycle confirms the generator is ready for the next outage while minimizing noise and fuel consumption — significantly quieter and faster than competing units' exercise cycles.

Robust angled louvers provide enhanced protection from moisture, dust, and vibration for maximum durability and longevity in the harshest outdoor environments, from coastal hurricane zones to upper Midwest blizzard country. The aluminum construction is corrosion-resistant by nature — no paint to chip, no steel to rust through. Cold Weather Ready — Down to -20°F with Warmers The 040787 operates in standard conditions down to 30°F. With the optional oil warmer, fuel regulator warmer, and battery warmer accessories installed, operating range extends to -20°F — making this generator suitable for year-round operation in the coldest North American climates. 7-Year Warranty — The Best in the Industry The PowerProtect+ 040787 is backed by a 7-year comprehensive warranty covering parts, labor, and travel — the longest standard warranty in the residential standby generator industry, valued at up to $849. Unlike Generac's 5-year and Kohler's 5-year warranties that reduce labor and travel coverage in later years, Briggs & Stratton maintains full coverage for the entire 7-year term. For non-emergency stationary use, coverage extends to 7 years or 1,000 hours. Model: 040787 Warranty: 7-Year Parts, Labor & Travel | 1-Year Enclosure Surface Rust & Corrosion | 3-Year Enclosure Rust-Through FAQ What can the Briggs & Stratton 22kW 040787 power in my home? With 22kW of output at 91.7A, the 040787 is sized for large homes requiring full whole-home coverage. It simultaneously powers a 5-ton central air conditioner, heat pump or furnace, electric range, refrigerator, freezer, sump pump, washer/dryer, lighting, home office equipment, and entertainment systems. With 45 kVA of motor starting power, it handles the largest residential startup loads without hesitation. Does the 22kW generator produce the same power on natural gas and LP? Yes — unlike many competing generators that derate significantly on natural gas, the 040787 delivers the full 22kW on both LP and natural gas. This makes it one of the only generators in its class to offer true fuel-neutral rated output, giving you full power regardless of which fuel source your installation uses. How does the 7-year warranty compare to Generac and Kohler? The PowerProtect+ 040787 carries a 7-year comprehensive warranty covering parts, labor, and travel for the full term — two full years longer than both Generac's 5-year and Kohler's 5-year warranties. Briggs & Stratton maintains full coverage throughout all 7 years; competitor warranties reduce labor and travel coverage in later years. This is the longest and most comprehensive standard warranty available on any residential standby generator. How close to my house can the 040787 be installed? The exclusive front-facing exhaust design allows installation as close as 18 inches from your home — listed and labeled to NFPA 37 per Southwest Research Institute testing. This is one of the closest approved installation distances available, giving homeowners with limited outdoor space more placement options than any competing generator. Can the 040787 operate in cold climates? In standard configuration the 040787 operates down to 30°F. With the optional cold weather kit — oil warmer (6959), fuel regulator warmer (6961), and battery warmer (6960) — operating range extends to -20°F, making it suitable for year-round operation across all North American climates including Canada.
