Product Description

Our most popular generators for backup power provide award-winning reliability and performance. When you lose power during an outage or storm, a hard-working 20kW KOHLER® generator keeps your appliances working, the heat or AC running and your security system on. Now also available in 3 phase.

RELIABLE.
Every KOHLER® generator is equipped with a heavy-duty, commercial-grade engine that stands up to extreme weather.

POWERFUL.
In just 10 seconds, your KOHLER generator automatically restores power to a 5-ton (60,000 BTU) air conditioner, major appliances and electronics.

PREMIUM WARRANTY.
We’ve got you covered with 5-year, 2,000-hour protection, and a corrosion-proof enclosure that’s built to last.

AWARD WINNER.
KOHLER generators have received several awards, including the Most Valuable Product (MVP) Award 2010 by Building Products magazine.

    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.


  2. If you need a Kohler generator buy it here.

    It's spot on with it's diagnostics and runs very quiet. During testing it handled the full load required of it. So far I'm happy with the Kohler recommendation.

    Kohler makes an excelent generator self-contained package. THis is my second oen bought for home use. APElectric has been wonderful tow ork with. Solid advice before selecting --- calling me to verify this is not a scam purchase or someone using my credit card --- prompt shipping --- one of the owner-managers even celled to ask if everything arrived in good condition. It doesn't get any better than that.


  15. Everything worked as planned.

    This was a really great decision from purchasing here to the unit itself. I documented the install with pictures here http://gladue.com/windsor/generator Purchasing your own materials and hiring your own contractors saves you about 50%. I wrapped up this project for about 10 grand with natural gas new install. It would have been about 20 grand if I just hired the Kohler dealer to do it.


  16. Couldn't find a better price online, thanks AP!

    The Kohler 20 kW residential unit seems to be a high quality, reasonably quiet , attractive unit and a good value for the money. The unit came lift gate delivered in just a few days. (Weighs about 500 lbs.) Pay by check and save 2% with AP Electric. I have only tested with a partial load but took it just fine. I have two ASCO 200 amp transfer switches in my electrical service so I use the "2 wire"start feature - not available on Generac similar residential units. It has a built in battery charger. The wiring compartment where the conduits come in is a little bit small but can be done. Hook it up using "Liquid-Tite"flexible conduit and fittings. Run a data cable in conduit if you want to use the On Cue software. I like the On Cue software and I run the exercise cycles manually through my computer when I am home. I like the e-mail notification feature.


  18. The service from AP Electric was great.

    I made a couple of calls and each time a person answered the phone immediately (no waiting) and was helpful in answering my questions and was pleasant. I ordered the generator Thursday afternoon and it arrived on Monday. That is great service. The Kohler generator enclosure is very attractive top quality and for sure the generator inside the enclosure is TOP QUALITY!


  19. Very happy!

    We are Contractors, Ordered a Generator, it showed up in 3 days. We checked the shipment and it was damaged, so I refused the shipment with the carrier. I called AP and explained the problem. The replacement was at my yard in 3 days. Tomorrow morning I am ordering 2 more units.
