Why KOHLER generators?

Reliable.

Inside the 12RES generator is a commercial-grade engine built to withstand extreme workloads year after year.

Off Grid.

Ideal for off grid applications. Non-standby rated KOHLER Command PRO® CH740 paired with ADC-RES controller allows saving battery voltage by going into hibernation mode.

Money Saver.

No pricey concrete pad needed. Your contractor – and your wallet – will appreciate the built-in mounting pad and easy-to-connect terminal block.

Premium Warranty.

Kohler is known for extraordinary reliability and performance, backed up with a 5-year or 2,000 hour limited warranty that covers parts, labor and travel for the full warranty period.

PowerBoost™ technology provides power to start large loads such as central air conditioners without dropping power to other appliances.

Extraordinary peak motor-starting capacity: 12RESV at 16.8kVA at 240V.

Premium power quality delivers exceptional digital voltage and frequency regulation to protect smart appliances and electronics.

Powered by reliable KOHLER Command PRO® engine, designed and tested for tough commercial applications; operation speed is 3600 rpm (the standard for air-cooled generators).

In just 10 seconds, your KOHLER generator automatically restores power to your heat or AC as well as appliances and electronics.**

ADC-RES Advanced Digital Control designed for today's sophisticated electronics.

Quiet, neighborhood-friendly operation with sound levels similar to a typical central air conditioner.

Steel enclosure with automotive-grade paint for advanced corrosion protection.

Runs on either natural gas or liquid propane (LPG); simple switching between natural gas and LPG in the field.
