Kohler 20rescl Review and Price History

Welcome to Kohler 20rescl Review. The Kohler Generator model 20RESCL-SELS is a 20-kilowatt air-cooled standby generator that provides electrical power to your home during a power outage. Norwall Power Systems sells the 20RESCL-SELS in a package with Kohler’s RTX 200 service-rated automatic transfer switch to provide your home with emergency electrical power whenever utility power is interrupted.

It meets emission specifications set forth by the EPA and the California Air Resources Board (CARB) and can operate on either LP gas or natural gas. The standby generator starts and runs automatically during an outage without intervention to keep your home supplied with power, even if you are not home. The OnCue Plus Generator System is included for remote monitoring at home or anywhere worldwide.

Why Kohler 20rescl Generator is a good Generator?

Fuel choices

The 20RESCL-SELS will run on either LP gas (propane) or natural gas, and the conversion is made in the field at the installation time. LP gas offers a higher power capability of up to 20 kilowatts versus 18 kilowatts for natural gas. The generator consumes 3.7 gallons of LP gas or 281 cubic feet of natural gas at a maximum load every hour. At half load, consumption is reduced to 2.2 gallons of LP gas or 161 cubic feet of natural gas. Fuel consumption depends on the load, and as the load varies from minute to minute, so does the fuel used.


Kohler’s Command Pro CH1000 air-cooled engine with hydraulic lifters powers the generator. The 999 cc V-Twin attains a maximum of 32 horsepower, easily turning the generating unit at 3600 rpm under full load conditions. This engine uses a fully pressurized oil lubrication system that holds three quarts of oil and includes an integrated oil cooling unit, both features offer extended, unattended run times. The maintenance schedule for oil and oil filter changes is 150 hours of run time annually, and air filters and spark plugs are 300 hours annually.

Transfer Switch

The RTX 200 amp transfer switch works directly with the DC2 controller onboard the generator. The transfer switch continuously monitors the utility line for electrical current and provides the data to the controller. When utility power is interrupted or falls below acceptable levels, a short delay before the engine start prevents the generator from starting during a momentary outage. The generator engine starts reaching operating speed, and the transfer switch moves the home’s power source to the generator.

After utility power is restored, the home is moved back onto utility power, the generator goes through an engine cool-down cycle, and then shuts down. The RTX-JFNC-200ASE 200 amp service entrance automatic transfer switch with load shed kit installed with NEMA 3R aluminium enclosure. The load shed kit monitors generator current and frequency to determine when to shed loads. Two HVAC relays to control two independent air conditioner loads are included.


The RDC2 controller works with the included transfer switch to automatically provide power during an outage. It includes a four-button operator interface with an LCD and LED indicators. The display provides a scrolling system status that includes eight functions: generator status, voltage and frequency, and maintenance reminders. More than seventy diagnostic messages are displayed for the engine, alternator, transfer switch, load control module, and programmable interface module. The included Ethernet port allows Kohler’s On Cue software to monitor and control the generator.

Appearance and Noise

The 20RESCL-SELS has a sound-dampening polymer housing that will not rust or corrode, even in harsh environments. The device measures 48 inches wide, 26 inches wide, and 29 inches high. The top of the housing is a lockable hinged lid for easy access to the controller. Underneath the lockable cover is a second cover that can be lifted to access the dipstick, filler, oil filter, and other generator components. The noise rating of 69 dB is comparable to many central air conditioning units’ noise.

Package Includes:

RTX-JFNC-200ASE, the automatic transfer switch for 200 amp load with load shed kit installed, Nema 3R aluminium housing (outdoor/indoor rating).

Flexible Fuel Line Connector: 

Please check the device manufacturer’s specifications for actual power requirements. Consult a Kohler Power Systems professional to calculate the exact requirements for your home power system. Local purchase of a 12-volt Group 51 battery with a minimum of 500 Cold Cranking Amps (CCA) is required.


Warranty Coverage: Stationary standby applications used in support of a commercial service source: five (5) years from the registration start date (or, if there is no start date, the date of purchase by the original end-user) or 2000 hours (whichever is comes first). Start-up service is not included; your local Kohler dealer can provide a start-up price.
