26kW Briggs & Stratton PowerProtect+ Standby Generator - 120/240V, Dual Fuel (LP/NG), Vanguard Engine, 7-Year Warranty - Model 040807

Briggs & Stratton 26kW PowerProtect+ Standby Generator – Maximum Whole-Home Backup for Large Homes and Luxury Properties The Briggs & Stratton 26kW PowerProtect+ Standby Generator (Model 040807) is the highest-capacity residential standby generator in the PowerProtect+ lineup — engineered for large homes, luxury estates, and properties with multiple HVAC systems, high electrical demands, and zero tolerance for outage-related disruption. When the grid fails, this generator detects the outage and restores 120/240V power within seconds, keeping every critical system in your home running exactly as if the power never went out. Powered by a Briggs & Stratton Vanguard® V-twin engine running at 3,600 RPM with full pressure lubrication, the 040807 delivers 26kW of stable, clean output on both natural gas and liquid propane — providing utility-quality power with less than 5% THD that is safe for sensitive electronics, smart home systems, medical equipment, and modern appliances. With 65.5 kVA of motor starting capability — the highest in the PowerProtect+ residential lineup — this generator handles multiple simultaneous large motor startups without hesitation. 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 040807 gives you more installation placement flexibility than any competing generator — protecting your home's exterior and landscaping while meeting tight clearance requirements in space-constrained installations. 65.5 kVA Motor Starting Power — Best in the Lineup With 65.5 kVA of motor starting capability, the 040807 is the most powerful starter in the PowerProtect+ residential lineup — 45% more starting power than the 22kW 040787 (45 kVA) and 77% more than the 13kW 040746 (37 kVA). It effortlessly handles multiple large HVAC systems, well pumps, sump pumps, pool equipment, and other motor-driven loads starting simultaneously — the scenario most likely to cause competing generators to trip or shut down during an 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 without an in-person service call — faster resolution, less downtime, and complete peace of mind whether you're home or away. Eco-Cise™ Weekly Exercise Mode The programmable exercise cycle — configurable from 16 seconds to 20 minutes — automatically verifies the generator is ready for the next outage. The short 16-second mode minimizes noise and fuel consumption; longer cycles are available for installations requiring more thorough weekly verification.

The corrosion-resistant aluminum construction requires no paint, produces no rust, and is engineered for decades of outdoor exposure in the harshest environments — from coastal hurricane zones to northern freeze-thaw climates. Operating range spans -20°F to 104°F for true year-round reliability across all North American climates. Clean Power for Every Device in Your Home With less than 5% THD and ±1% electronic governor frequency regulation, the 040807 delivers utility-quality electricity that is safe for every device in your home — computers, smart TVs, medical equipment, smart home hubs, EV chargers, and sensitive appliances that would be damaged by the voltage fluctuations produced by lesser generators. This is the standard that modern homes demand and the PowerProtect+ delivers it consistently. 7-Year Warranty — The Best in the Industry The PowerProtect+ 040807 is backed by a 7-year comprehensive warranty covering parts, labor, and travel — the longest standard warranty in the residential standby generator industry, two full years longer than both Generac's 5-year and Kohler's 5-year warranties. Unlike competitors that reduce labor and travel coverage in later years, Briggs & Stratton maintains full coverage for the entire 7-year term. This is the most comprehensive warranty you can get on a home standby generator, period. Model: 040807 Warranty: 7-Year Parts, Labor & Travel FAQ What can the Briggs & Stratton 26kW 040807 power in my home? With 26kW of output and 65.5 kVA of motor starting power, the 040807 is designed for large homes and luxury estates with multiple HVAC systems, high-demand appliances, and whole-home backup requirements. It simultaneously powers multiple central air conditioners, heat pumps, electric ranges, refrigerators, freezers, sump pumps, well pumps, pool equipment, lighting, home offices, and entertainment systems — with enough headroom to handle multiple large motor startups at once. How does the 26kW 040807 compare to the 22kW 040787? Both are PowerProtect+ units with 7-year warranties, front-facing exhaust, EnergyTrak monitoring, and 186 mph enclosures on the same Vanguard engine platform. The 040807 delivers 4kW more output and 65.5 kVA of motor starting power vs. 45 kVA on the 040787 — a 45% increase in starting capability. The 040807 is the right choice for homes with multiple HVAC systems, larger square footage, pool equipment, or well pumps. The 040787 is the right choice for most large single-family homes with a single HVAC system and standard electrical loads. Does the 26kW generator produce the same power on natural gas and LP? Yes — the 040807 delivers the full 26kW on both LP and natural gas, with no derating on either fuel. This is a genuine differentiator from competing generators that commonly derate 10–20% on natural gas. You get full rated power regardless of which fuel your installation uses. How quiet is the 040807 compared to competing generators? The 040807 operates at just 63 dB in low idle mode and 65 dB during normal operation — making it one of the quietest high-capacity residential standby generators available. For reference, 65 dB is roughly equivalent to a normal conversation at close range. This makes the 040807 suitable for neighborhoods with HOA noise restrictions and properties where generator noise is a concern. Does the 040807 start automatically during a power outage? Yes. When paired with a compatible automatic transfer switch (ATS), the 040807 continuously monitors utility power and starts automatically within seconds of detecting an outage — restoring power to your home with no manual intervention required. An ATS is required for automatic operation and is sold separately.
