Residential Features & Options of 12kW




How Much Power Do You Need?

Just add up the essential systems and conveniences in your home that rely on electricity.

To select the power system that’s right for you, use the sizing options below:

  • 8.5 kW: Furnace Fan, Refrigerator/Freezer, Sump Pump, lighting, Well Pump, Television/Radio, and Computer.
  • 12 kW: Same as 8.5kW, plus, Home Ventilation Fan, Garage Door Opener, Security System, and Central Air System.

Due to the cycling nature of many of these devices, any KOHLER® generator you select may not run all the appliances simultaneously. Check the manufacturer’s specifications for actual power requirements. Consult a Kohler Power Systems Professional for your exact residential power systems requirements. Professional installation required.

The new Kohler 12 kW generator is the only generator in its class powerful enough to start and run a typical 4-ton (48,000 BTU) central air conditioner in the event of a power outage. Until now, a 17 kW or larger generator was required to run central air along with all other major appliances.




Appliances/Equipment For Which Intend to Use Installed Standby Generator



Residential Generators

Installation and Operation
Your KOHLER® residential backup generator system can be sized and wired for your home in one of two power distribution scenarios:

Essential Loads Power Distribution
This power distribution scenario isolates and supplies electrical power only to those essential devices that must function during a power interruption. Examples of devices and appliances that may be considered essential are:

  • Furnace
  • Lighting
  • Sump Pump
  • Refrigerator/freezer
  • Security system

These devices are wired through a secondary, or essential loads, distribution panel. This allows a smaller generator to be used.
