  •  Unit approved for stationary standby applications in locations served by a reliable utility source and not compatible for Off-Grid applications.   

The 20kW Kohler 20RESC keeps the family safe at home when grid power fails. In only 10 seconds, this Kohler generator restores power to a 5-ton (60,000 BTU) air conditioner, major appliances, and electronics automatically. Users can run the business as usual till grid power is restored. This 50Hz/60 Hz home generator generates 20kW on LPG and 18kW on natural gas. The model is offered in both single-phase and 3-phase. The single-phase system produces a single wave of power while the 3-phase system generates three waves of power, delivered in a sequence to ensure a nonstop flow of power that never drops to zero. Kohler 20RESC has an exceptional peak motor-starting capacity at 41kVA at 240V. It is convenient to switch between natural gas and LPG fuels. Users prefer to connect it to the kitchen gas line for an unlimited supply of fuel, so they can run it for hours at no end during a storm. Kohler residential standby generators are very reliable and run as quietly as an air conditioner. For total peace of mind, the optional OnCue Plus system keeps users connected to the generators while on the go. They can use their smartphones, tablets, laptops, and PCs to check the oil level, runtime, generator temperature, battery status and so forth. Generators made by Kohler, an award-winning company come with the latest features to meet the changing market needs.
