Features

  • 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.
  • 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
  • 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.
  • Digital electronic isochronous governor
  • Digital voltage regulator
  • LED display provides diagnostic capability
  • DESIGNED FOR EASY INSTALLATION
  • Polymer base eliminates the need for a concrete mounting pad, reducing installation time and cost
  • Fuel and electrical connections through the enclosure wall eliminate the need for stub-ups through the bottom
  • EMISSIONS CERTIFICATIONS
  • California Air Resources Board (CARB)-certified for both LP vapor and natural gas (field-convertible)
  • Meets Environmental Protection Agency (EPA) nonstationary unit requirements

Alternator features:
  • Compliance with NEMA, IEEE, and ANSI standards for temperature rise
  • Self-ventilated and drip-proof construction
  • Vacuum-impregnated windings with fungus resistant epoxy varnish for dependability and long life
  • Digital voltage regulator with ±1.5% no-load to full-load RMS regulation
  • Rotating-field alternator with static exciter for excellent load response
  • Skewed generator construction produces a smooth AC waveform

Engine features:
  • Simple field conversion between natural gas and LP vapor fuels while maintaining emission certification
