My experience with Kohler, do not buy.
Charles D. Martin
Great project and it's really unobtrusive... looks like a deck box more than a generator.
Christopher Powell
I should not have to continuously call/email/write to have a warranty issue resolved.

For anyone interested, I just finished installing a Kohler 20kW 20RESA residential generator, matched with a Kohler RXT-JFNC-200ASE whole house automatic switch. I chose the Kohler unit because it has a composite noise dampening enclosure, 5 year warranty, Kohler onCue remote online monitoring (it emails and texts me), and basically is worry free except for annual maintenance.

I dug my trenches, and poured a 6" thick 3'x5' pad over 2" of gravel, about 3' from my house with the exhaust (left side) angled away from the house. It took 4 guys to help set the 530lb unit in place. Thankfully Kohler makes this easy, since there are two holes in the front and back to insert poles (I used spud bars) to make carrying it like a litter possible. It's heavy though. I bolted my unit to the concrete pad to prevent movement from vibration, and a little more security.

The Kohler RXT-jfnc-200ASE ATS switch is a whole house switch mounted externally. I used a local Kohler Authorized electrician for the electrical hookup. They ran the service line from the the electric meter straight to the ATS switch. Then from the ATS switch into the house. The generator of course hooked into the ATS to provide power, but also needed Belden 9402 for the control circuit. An additional 15A 115v circuit was run from the generator to the inside panel.. this was for the battery trickle charger and the carburetor heater. The last run was the low voltage shielded twisted pair Ethernet that went from the generator to my Ethernet switch inside. As mentioned, I picked up a carburetor heater, since I live in Ohio and it gets below 0F... and an Optima Sealed AGM group 51 starter battery. I bought the generator this summer when they offered free software, so I already had my activation key from Kohler.

Ordered Kohler 20RESAL-SE from Home Depot. It was shipped from Kohler, WI. and delivered by Estes Trucking to my home by the Estes truck driver using a lift gate and pallet jack. Arrived in perfect condition. The Home Depot generator installer did NOT handle Kohler generators, however, so I had to find my own. Other local Kohler generator installers seemed not seriously interested in my business since I had bought the generator from Home Depot instead of thru them. However, I found a local licensed electrician and licensed plumber that sold and installed Generac generators who provided what I considered competitive bids. Neither, however, employed an in-house Kohler certified technician for the start-up. I was, however, able to obtain one from Loftin Equipment (Houston, TX) who took care of the start-up and warranty activation - but at a price, $536.25.

I decided to go with a second, dedicated gas meter since my existing gas meter would have required an upgrade and it was about 160' from the meter to where I wanted to install the generator. The second meter was installed within about 5' of the generator. It was also the higher output (2 lbs./psi regulator) meter. I had a 1" galvanized gas line run between the generator and the new meter. I used the 1" Maxitrol 325-5AL regulator (Grainger number: 5JC45) to reduce the gas pressure to 7-11" max W.C. (According to the natural gas technician at W.W. Grainger, neither the 1/2" nor 3/4" valves could provide the specified natural gas volume to run the Kohler 20RESAL at full load.) I obtained a prefab GENPAD brand concrete pad, leveled and set the generator on it myself before getting the electrician or plumber out to do any of their work. The generator is very heavy (500+ lbs.).

Had the generator (20RESAL) installed for 6 months now with load shedding module. Never has run correctly (and was installed, checked and started by a Kohler rep).

There's a problem with the throttle - keeps pulsing power which leads to dirty power to the home (lights pulse too, UPS' won't charge due to dirty power) and after 4 visits they still haven't got it right. This is still a problem after the gas utility installed the largest meter possible (800) which is only 3 feet from the generator. We know gas supply is not an issue.

Kohler rep says the throttle problems are common. Kohler, you have let me down. Would never recommend a Kohler to anyone based on my experience. Still looking for a solution. Premium price, but does not live up to its reputation or promise.

Update
Finally, after five attempts, the Kohler rep dismantled the carburator. The gasket was cut badly and was interfering with part of the throttle. Quality control was lacking.

I purchased this product through a local Kohler installer. The unit has had it's minor issues, but the biggest issue I have is trying to get Kohler to respond to the problems I have had with the unit. I should not have to continuously call/email/write to have a warranty issue resolved. The base on my Kohler unit has cracked twice in the same spot. At this point I would not recommend this Kohler generator to anyone and I'd have reservations recommending any generator product they produce for residential use. The maintenance contract is also way out of line for essentially an annual oil change and "priority" placement on a service call in an emergency. I was quoted $625 per year, overpriced in my opinion. The unit does what it is supposed to do too bad Kohler isn't as functional.
