Kohler® 12RES Small Business & Residential Generator


MORE POWERFUL PERFORMANCE
KOHLER’s exclusive PowerBoost technology provides greater motor starting capability for large loads such as central air conditioners while still running other home appliances and electronics.

The KOHLER 12 kW generator is powerful enough to start and run a typical 4 ton (48,000 BTU) central air conditioner, while still running other home appliances and electronics

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

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.
