The Most Powerful Home Standby Generator
PowerProtect 26kW3
The PowerProtect 26kW was the first 26kW home standby on the market, and it remains the most powerful air-cooled home standby generator today. With 26kW on reliable power, it can power large homes, multiple air conditioners, pools and more so you don’t have to sacrifice anything during a power outage.
Only Briggs & Stratton provides maximum power with NGMax!
Currently, over 70 percent of homes in the U.S. have access to natural gas, yet the power output rating you see on most home standby generators is for the power generated while operating on liquid propane fuel. That’s because liquid propane fuel is more “energy dense” and thereby produces power more efficiently than natural gas. It’s a marketing tactic - manufacturers want to promote the higher power output on liquid propane even though most owners of generators are using natural gas. Briggs & Stratton’s NGMax technology provides maximum power, whatever fuel source is used.
More Power For Your Money
When comparing Briggs & Stratton 18kW and 22kW home standby generators’ power output on natural gas (NG) and the Manufacturer’s Suggested Retail Price (MSRP) against that of leading standby generators of similar or more output, Briggs & Stratton provides the best value and lowest cost per kilowatt (kW).
The math is easy to do. Simply divide the MSRP of the generator by the kilowatts (kW) of power output on NG. So whatever the fuel, when you choose a Briggs & Stratton home standby generator you get the most power for your money.
