Kohler Generators


Known for extraordinary reliability and performance, Kohler has introduced a new line of smaller units that are powerful enough to run up to a 4-ton air conditioner. These compact powerhouses can run most of your critical loads such as sump pumps, wells, lighting, and outlets when you need it the most and at a cost-effective price. Utilizing a load control module can enhance these smaller units to provide enough power to run most 1000-2000 sq. ft. homes


Kohler Generators' most popular sizes are their 14kW/20kW models. Providing award-winning reliability and performance, these units can run an entire average-sized house from 1500-3,000 sq. ft. with no issues. A load control module paired with a 14kW/20kW Kohler generator can be utilized to control some houses that may have larger electrical demands such as multiple AC condensers or other high energy loads.


For providing reliable power to large residential homes 4,000 sq. ft. and up or a small business, the 38kW/48kW lineup will provide reliable power during your next bad storm or power failure.
