Do not buy this generator unless you want the sound of a helicopter right outside your window.

This is a turd, plain and simple, it runs its weekly exercise, but does not produce power.

First Time Not Using A Local
By Jerry M
Delaware
Purchased 08/03/2023 |
Review Posted 09/15/2023
This was our first time buying online. It all went well, the only problem was that generator had a small area that had the paint rubbed off, the customer was ok with a little touch up paint. Over all smooth process.

Great Generator
By Michael W

Review Posted 02/02/2023
First off shipping from this company is always amazing! 2nd one of these I have installed on my houses. One solar, this one was grid tie, both propane. Generator works as it should. Conversion to propane is no longer an orfice swap. Valve turn and solenoid plug. Sticker on side on 20k said to unplug solenoid. Kohler directions say to unplug on 14k version, says nothing about 20k. My 20k would not start with plug unplugged. It does run with plug installed (sticker should not be there on 20k Kohler). That was only hiccup and was Kohler direction issue not this company, these folks are awesome!

Kolher Not So Helpful
By Carl S
New Jersey
Review Posted 01/10/2023
Genetators Direct did well, Kohler not so much .The generator came with mislabeled screw terminals which cost me several hours to diagnose. Once I corrected them it ran fine .The Kohler service people were just about useless all they wanted to do was blame it on me and direct me to a local dealer.

Electric Generators Direct Is Easy To Work With!
By Bridget P
Wisconsin
Review Posted 11/15/2022
My generator was delivered with a truck and loaded into my garage. I paid an extra small fee for this service, but it was worth it. I saved money by purchasing my generator from Electric Generators Direct and getting a certified Kohler installer to install it.

Quiet Generator

Review Posted 10/31/2022
So far so good, easy directions for installation and runs very good— and a lot quieter than I thought. Only wish is that kohler would allow an accessory of putting a CT so we could measure AMPs

This Is About More Than The Generator
By Pete G.
Butler, Pennsylvania
Purchased 04/07/2022 |
Review Posted 05/03/2022
The generator is just what I expected,,, made in America quality at a fair price and durability I can rely on. What I want to focus on is Generators Direct. I called them on a Thursday afternoon and after a satisfying conversation with a very nice lady I put my order in for a Kohler 20K RCA. The following Tuesday morning the generator was in my driveway. You can't get a letter delivered that fast any more,,, Wow ! Delivery was made by a very nice gentleman who dropped his lift gate to the level of my trailer and pushed it right in. The whole process of buying from EGD was a truly refreshing experience and I give them 5 stars also. They know how to run a business.
