Briggs & Stratton 040787 22kW PowerProtect™ Standby Generator
The Briggs & Stratton 040787 22kW PowerProtect™ generator is a high-capacity residential standby generator designed to provide reliable whole-home backup power during outages. Built for automatic operation, this generator continuously monitors utility power and restores electricity within seconds, ensuring your home’s essential systems stay up and running when the grid goes down.
With 22kW of standby power and 120/240-volt single-phase output, this generator is capable of powering large homes with multiple HVAC systems, major appliances, lighting, and critical circuits. It is an ideal solution for homeowners looking for full-home backup capability, offering enough capacity to handle higher electrical demands while maintaining stable and reliable power output.
At the core of the PP22 is a Briggs & Stratton Vanguard® V-twin engine, engineered for durability and long-term standby performance. Operating at 3,600 RPM with a full pressure lubrication system, the engine is built to deliver consistent power during extended outages. The generator produces less than 5% total harmonic distortion (THD), delivering clean, utility-quality electricity that protects sensitive electronics, smart home systems, and modern appliances.
Designed for outdoor installation, the generator features a corrosion-resistant aluminum enclosure and operates at sound levels as low as 64 dB in low idle mode and 68 dB during normal operation, making it well suited for residential environments. The system includes an advanced controller with programmable exercise cycles, real-time monitoring, and diagnostic capabilities to ensure the generator is always ready when needed.
