24kW to 26kW Generators

New 24kW and 26kW Generators from Generac and 26kW Briggs and Stratton Generators put out over 30 percent more power than the 20-kilowatt models that topped the market just a few years ago. Larger homes and small businesses have the backup power they need with a more affordable price tag compared to liquid-cooled models with a similar capacity. The air-cooled generators take up half the space of larger and more complex liquid cooled generators and install with as little as 18 inches between the home and generator—subject to local building codes.

The generators cool themselves with air blown over the alternator and engine by a fan. This method is less complex than a liquid-cooled generator that uses a cooling system similar to a car with coolant pumped through the engine and radiator.

Briggs and Stratton put their headquarters in Milwaukee Wisconsin. Generac placed their headquarters in Waukesha, just outside of Milwaukee. Both companies build their generators in the United States with USA made parts and some foreign-built parts.

*Standby Generator Installation Requires an Automatic Transfer Switch. Models sold without a transfer switch require a compatible Automatic Transfer Switch Installation.
