Kohler 20RESC 20kW Generator Features:

Kohler 20RESC 20kW Generator features:

Kohler 20kW 50Hz/60 Hz home generator runs on a powerful Kohler CH1000 4-Cycle, 30.9 HP, V-2 engine with maximum 3600 RPM. The heavy-duty, commercial-grade engine stands up to extreme weather. This dual fuel generator offers advanced voltage and frequency regulation. Excellent power quality protects all valuable electronics. 20RESC is ideal for use with computers, laptops, cell phones, and tablets.  

  • The cylinder head is made of aluminum while the fuel solenoid valves are made of steel. The pistons are made of aluminum alloy.
  • The oil tank stores 1.9 liters/2 quarts of oil. It has an oil drain extension with a shutoff valve. The full pressure lubrication system makes it a low maintenance model. 
  • The RDC2 controller provides integrated control for the generator set. The 2-line backlit LCD screen display with adjustable contrast is easy to read. It displays status messages and system settings. OnCue Plus allows users to check the real-time status of the generator from remote locations using laptops, PCs, and smart phones. 
  • PowerBoost™ technology helps start large loads such as central air conditioners quickly without dropping power to other appliances.
  • The enclosure is corrosion-proof and impact tested to -30°F. It is also ideal for seaside environments.
  • Digital voltage regulation guards all sensitive electronics against harmonic distortion and unsteady power.
  • Installation is easy with a simple terminal block for field connections.
  • Certifications and Listings include cUL, UL 2200, CSA, EPA and GOST (Russia).
  • 5-year/2000 hour premium warranty for on-grid applications. 

Kohler 20RESC is an air-cooled model that keeps the family safe and comfortable during a power outage. This home standby generator keeps supplying high-quality power to air conditioners and other home appliances when grid power fails. In a matter of seconds, this Kohler generator restores power to a 5-ton air conditioner, major appliances, and electronics.  

This Kohler model has an outstanding peak motor-starting capacity at 41kVA at 240V. It is easy to switch between natural gas and LPG fuels while maintaining emission certification. Connect it to the kitchen gas line for an unlimited supply of fuel. 

The single-phase system generates only one wave of power while the 3-phase system produces three separate waves of power, delivered in a sequence to ensure a continuous uninterrupted flow of power that never drops to zero. This makes three-phase generators more desirable than single-phase generators.  

This model can be installed outdoors at home as a standby generator. The model has a polymer base, which eliminates the need for a concrete mounting pad. This reduces installation time and cost. Buyers get free shipping and free technical support.

    Great Investment Soo Far

    Posted by Nathan on Sep 10, 2018

    Was a little worried about ordering the generator online. Didnt like the fact that I was spending $4k on something from someone I never met. But I am happy I did. The generator was delivered in great condition. I installed everything myself and saved lot of $$. No problems so far. Only ran the generator for 30mins so far for a test run. I recommend buying the concrete pad. Generator bolts right to it. Very easy install.

    Great Experience - Sales, Shipping and Installation

    Posted by Joe Dame on Jan 02, 2018

    I recently purchased a Kohler 20kw generator package and I highly recommend AP Electric as they were great. The purchase and shipping was very easy to arrange. The generator quickly arrived at our NH home and the truck driver delivered it right to the installation area - no heavy lifting required. I also ordered the Kohler concrete pad, battery, cold weather kit and maintenance kit with the generator. Everything arrived in perfect condition - no issues. For the installation, I pulled permits and hired my local electrician and LP gas fitter. The installation was straight forward as I used the matching Kohler 200 amp ATS. Please note that Kohler uses a Belden 4 conductor shielded control cable to connect the ATS and generator. I bought 100 ft of the specified cable online so it was available for the electrician. The generator is fueled by a 500 gallon underground LP tank which was already in place. I highly recommend the cold weather kit if you live in northern areas. The kit included a battery warmer, carb heater and lp regulator heater. The kit was easy to install - the heaters are 110 V and plug into the generator's internal 110 V outlet. During the last 2 weeks, the temperature in our part of NH has been -10 to -20 degrees at night. No worries though as the generator starts right up even at these extreme temperatures. We also had an ice storm last week and the grid power was out for several hours at a time over a 3-4 day period. The generator performed as expected and we had plenty of back-up power for cooking, lighting and heat. Overall, I am very satisfied with the generator and recommend both AP Electric and Kohler to anyone looking for a reliable back-up power system.

    Great Product

    Arrived as advertised. Great information from AP electric staff. Electrician, gas company and local Kohler dealers were terrific. Lost power for 4 hours a week later and everything worked perfectly.

    Get a Kohler, you'll be glad you did

    The 20 RESC and RXT Auto transfer switch arrived quickly, good job AP Electric. It took a few weeks to line up my contractors for electric and gas pipe run from the LP tank. I did exchange my 500gal tank for a 1000gal tank, keeping in mind the BTUs/hr needed to run the GEN at full output (~350,000), and how temps below 15F would limit the GEN startup due to lower vapor pressures in a 500gal tank. The GEN runs it all (3+ ton Geothermal Heat/AC), no problem. I had the nearest Kohler dealer do the startup and inspection to start the warranty at that time. The whole project came in under $7000, not including the LP tank upgrade. Very pleased with the GEN, AP electric and my local Kohler dealer. If you have a long run between the GEN and the AUTO transfer switch, I highly recommend a Kohler as it can handle larger gauge wire than other generator brands (I used 1/0 copper, it delivered 242V to the Auto transfer switch, 36' from the GEN). The Kohler GEN is a perfect match for our all electric house, which is out in the country about 6 miles from town.

    Go with Kohler

    Posted by Mike Stoner on Oct 21, 2016

    I have had automatic standby generators at my homes for many years. All have been Kohler. I've found them to be highly dependable and reliable and would own nothing else.

    I was able to chat online with a representative from AP Electric (Cristina), and then when I was ready to order a week later, I just called the customer service rep's extension. The whole process took about 5 minutes. I received updates on my delivery and it was delivered on the day promised.
