The KOHLER 20kW Home Standby Generator is great to have for power outages.
I can now keep my Mother's oxygen tanks full while storms are taking down trees and power lines. Not to ignore the saving of food in refrigerator & freezer.

Ordered and installed 20KW with 200 amp panel in Michigan 11-2021. Shipping was fast and arrived damage free on time. This unit is very, very heavy. Do not short cut on the site prep. I used a concrete pad on top of pea gravel and it has not settled. The transfer panel is large and has to placed in a area that is accessible. The transfer panel is 200Amps and MUST be matched to a 200 amp service panel that wired in your building. When power goes out the switch over to generator power is very short time, just a few seconds after it started. This generator is so quiet. We don't know its running in the house. We have a 4 ton air conditioner, well, sewer, grinder pump, hot tub, two fridges, all the normal appliances, lights, gas heat, gas dryer. The highest load was 48% of capacity. This unit is set up for ethernet remote monitoring which can be viewed from an app on your phone. It has 183 hours of time on it now and has worked perfectly during power outages. I have both this model at our primary home and a Generac Guardian at a remote Michigan vacation home. Overall they both work well, but prefer the Cummins due to being quiet and switch over time. Would recommend.

I messed up and ordered the wrong auto transfer switch and Aharon was sympathetic and took care of the credit and we got the correct one ordered. Wow got me out of a tough spot. Not many companies step up to help you. Thanks again. You won’t go wrong buying from this company.

Heavier than I thought it would be,but so far its been amazing.Thank you

Fast shipping, un packed added oil, installed battery added fuel and generator started right up. Plugged in trailer and ran under load for 4 hours no issues. Thank you Generator Mart

Works great. Remote start is awesome.
Runs at high altitude no problem. Would definitely recommend.

I can’t say enough good about generator Mart. Even though I had just missed the sale I got it anyway, I was only a few hours late on the sale. The gentleman that helped me was very courteous. Took the transaction very quickly and I had my generator within five or six days. I have not installed it at this time but it looks great and I’m sure it will work as good as it looks. My neighbor bought the same Kohler generator that I did and we installed it this week. It works perfect. We are both Electrical contractors and will recommend Generator Mart to everyone we know.

Generator Mart had the lowest price on two Lithium-Ion 5.0Ah batteries, with free shipping and deliver was fast.
