Kohler 14 RESAL-200 14000 Watt Standby Generator

Kohler 14 RESAL 200 - 14kW Standby Generator

Kohler 14 RESAL 200 – 14kW Standby Generator

The Kohler 14RESAL-200 watt air cooled standby generator is designed to automatically deliver power to your whole house in times of power outages. It comes with a 200 Amp Whole House Automatic Transfer switch.

Since the 1920’s, Kohler has been making generators and power units. Today Kohler is known for its innovative generators and is the leader in generator technology for the residential, commercial as well as the industrial markets in standby generators. Kohler generators are quality tested from the start to the finish which makes them one of the most reliable generators on the market.

All their generators have a commercial grade engine to ensure long life and they can handle extreme conditions. Kohler generators have one of the best warranties at 5 years and 2000 hour to give you peace of mind.

Power Output and Generation

The Kohler 14 RESAL-200 standby generator is powered by a Kohler Command Pro 725 cc OHV 4 cycle V twin cylinder air cooled engine which is designed to run on natural gas or Propane at 3600 rpm. This unit is EPA and CARB compliant using both LP and NG.

This generator can deliver 12,000 watts when running on natural gas and 14,000 watts when running on propane. The standby system is an auto-start design via a local battery and depending on seller bundling the battery is usually not included.

The engine is equipped with an oil drain extension with shutoff valve for maintenance.

Electrical Generation and Usability

Auto Transfer Switch

This standby generator is designed to be hardwired to the either the 100 amp or 200 amp Model RXT automatic transfer switch. The 14RESAL has line circuit breaker of 70 amps (which is more than the unit can produce).

It will provide up to 58 amps on LP and 50 amps on NG, which is approximately able to run several 15 amp circuits at less than full rating. Kohler specifically indicates to not use the Model RRT xfer switch with this unit.

There are no additional outlets at the generator, although there does exist a way to wire in receptacles to the stub up locations. We suggest that you use a qualified electrician and ensure use of outdoor rated parts if you attempt to add outlets.

Kohler has a unique PowerBoost ™ voltage regulation system at ±1% for instant response to load changes providing a quality regulated power supply for sensitive electronics.

See sections below for additional details of some of these great features of the controller.

Fuel Type and Noise Levels:

With ability to use either NG or LP the 14RESAL-200 generator is meant to be connected to the main gas supply which is used for heating in your home. The ability to connect direct to natural gas supply or large LP tank provides for long duration run times.

Fuel consumption published by Kohler for NG at 50% load is 124 cfh
and on LP at 50% load is 60 cfh.


This generator is comparatively quiet when running, producing only 67 db of sound at full load and 63db level when exercised or idling. This is less than most portable generators at half this output. This talks well to the enclosure characteristics and the use of the flame-retardant foam. Although this could be an annoying level if located close to your outdoor activities or open window, it is not much worse than many outdoor air conditioners units.

Dimensions and Weight

The Kohler 14RESAL-200 standby generator is relatively compact with overall dimensions of 48 x 26.2 x 29 inches (L x W x H) and it weighs in at 410 lbs. This is definitely not a portable generator and is intended to be stationary at this size and weight.

Typical Uses and Needs

The Kohler 14RESAL-200 14,000 watt air cooled standby generator is meant to be used as a standby power source for your home or small business in times of power outages.

This generator turns itself on automatically when it detects a loss in the utility power supply and with the automatic transfer switch changes the power source from the utility to the generator. With this generator, no matter whether you are at home or not, if there is an outage of power your home will always have power.

This generator supplies very clean electricity, which refers to the highly regulated voltage with low harmonic distortion, meaning all your sensitive electronic equipment can be safely run when the generator is supplying power.

With capability of supplying 14,000 or 12,000 watts of power, you can run your entire household without worry with this generator. This generator is also a great fit to be used as a backup power supply source for your small office or store.

Display & Control Panel, Start-up

Kohler DC2 controller

Kohler DC2 Controller

The control panel of the Kohler 14RESAL standby generator can be found under the roof of the generator. It is situated to the extreme right, this is a digital controller which provides integrated control

This controller for RESAL models uses a digital control (DC2) which provides for integrated control with Kohler’s Model RXT transfer switch, programmable interface module and load control module.

There are a number of other features such as date/time, engine temperature monitoring, governor to maintain steady state speed, voltage regulation, auto start, exercise modes, USB connector for tech connection, integral Ethernet connector for Kohler’s OnCue, battery charger for built in battery, remote hard wire connection to transfer switch, and diagnostic messages.

The controller has a 2 line LCD screen which displays system settings and status messages at 16 characters per line and the screen is easy reading and visible in direct sunlight..

The controller has a 3 button keypad which include OFF, RUN, AUTO buttons for the normal operation of the unit. It also has a exercise button to manually run the engine through a test cycle, and when controller is OFF will reset the OnCue password. (see more below)

The Off button lets you turn the generator off. This button also clears any faults and resets the controller.

The RUN button starts the generator and the AUTO button lets you put the generator in the standby mode. The Arrow buttons help you navigate through the menu and change the settings. The LED lights indicate the status of the generator. The RUN LED light lights up when the generator has been started manually by pressing the RUN button. The OFF LED light lights up and flashes when the generator and the remote controller are off.

In the AUTO mode this light flashes to indicate a fault shut down. The AUTO LED lights up when the generator is in the standby mode. The Utility Power Available LED lights when utility power is available. The Building On Utility Power LED lights when power is connected to the utility through the transfer switch. The Generator Power Available LED lights up when the generator power is available and the Building On Generator Power LED lights up when the load is connected to the generator through the transfer switch.

There actually 30 status points you can monitor.

The main status displays are:

  • Voltage and frequency
  • Engine temperature
  • Oil pressure
  • Battery voltage
  • Engine runtime hours
  • Maintenance reminders
  • OnCue status (connected/disconnected)

Start up

The Kohler 14RESAL standby generator has an automatic transfer switch that monitors the utility’s power. When in the standby mode the generator turns itself On automatically when it detects a loss in the utility power and transfers the load from the utility to the generator. The generator can also be started manually by closing the remote switch which will start the generator. You can also start the generator by pressing the Run button on the generator to start it immediately.

Shut down

When the generator is in the AUTO mode it turns itself Off automatically when it detects that the power has been restored by the utility company. It also switches the load back to the utility from the generator. To stop the generator manually you need to press the OFF button which stops the generator. You can also stop the generator by opening the remote control switch.
