OVERVIEW
Affordable, commercial-grade power for basic power needs. When a bad storm or utility failure knocks out your power, the 12RES KOHLER® generator keeps your lights on, fridge cold and sump pump working. This generator will power most appliances in smaller homes, or a few critical items in larger homes.*
  • 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 hibernating mode.
  • Money Saver - No pricey concrete pad needed. Your contractor – and your wallet – will appreciate the built-in mounting pad and easy-to-connect.
  • Premium Warranty - Kohler is known for extraordinary reliability and performance and backs that up with a 5-year or 2000 hour limited warranty that covers parts, labor and travel for the full warranty period.
THE POWER YOU NEED
  • PowerBoost™ technology provides the power to start large loads without dropping power to other appliances

THE CONVENIENCES YOU EXPECT
  • 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
