Each home backup power system from Kohler includes the generator unit, battery charger, composite pad, and optional transfer switch on the 15RES. The automatic transfer switch can be selected with or without load center and from 100 to 400 amps. Frequently
referred to as the “brains” behind the generator, the transfer switch continuously monitors
utility power and within seconds of any power outage automatically transfers power from
the utility to your generator. The generator alone now supplies your home’s power. When
utility power is restored, the transfer switch signals the generator to shut down, returning
your home’s power demand to the utility grid.
A KOHLER commercial-grade residential power system is the ultimate protection during unexpected power outages and keeps your family living life to the fullest. It’s what Kohler customers have come to expect from a world leader in home comfort products.
· More Powerful Performance
· Kohler·s exclusive PowerBoostª technology provides greater motor starting capability for large loads such as central air conditioners while still running other home appliances and electronics.
· Kohler·s 15kW residential generator is powered by a liquid-cooled automotive engine to provide heavy duty power for your home or small business needs.
Safer Power for Sensitive Electronics
· Many power sources can damage and degrade sensitive home electronics due to unstable power quality or high levels of total harmonic distortion (THD). KOHLER residential generators protect all of your valuable appliances and sophisticated electronics with cleaner, safe and stable power that meets strict utility requirements and IEEE standards for THD.
Quieter Operation
· Quiet operation: 65 dB(A) at 7 m, similar to a typical vacuum cleaner
· 61 dB(A) With Optional Sound Enclosure
· Sound enclosure maintains neighborhood solitude whether you are in self-test or full operation mode
Faster Response
· While many competitive products can leave you in the dark for 25 seconds or more during an outage, KOHLER generators restore power in as little as 10 seconds.
Superior five-year limited warranty included
· KOHLER residential generators are commercial grade and have the warranty to back it up. This generator is supported by a premium five-year limited warranty.
