The Kohler Power Systems model 20RESAL-SA7 is a 20 kilowatt, air-cooled standby generator that provides electrical power to your home in the event of a power outage. Norwall Power Systems sells the 20RESAL-SA7 in a package with Kohler's RXT 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 20RESAL-SA7 will run on either LP gas (propane) or natural gas and the conversion is made in the field at the time of installation. LP gas offers a higher power capability of up to 20 kilowatts versus 18 kilowatts for natural gas. At maximum load, the generator consumes 3.7 gallons of LP gas or 281 cubic feet of natural gas every hour. At half load, consumption is reduced to 2.2 gallons of LP gas or 161 cubic feet of natural gas. Fuel consumption is dependent on the load, and as the load varies from minute to minute, so does the amount of fuel that is 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 maximum 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 that offer extended, unattended run times. The maintenance schedule for oil and oil filter changes is 150 hours of run time or annually, and air filters and sparks plugs is 300 hours or annually.
The RXT 200 amp transfer switch works directly with the DC2 controller on board 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 engine start prevents the generator from starting during a momentary outage. The generator engine starts, reaches 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 RXT-JFNC-0200ASEQSR2 200 amp service entrance automatic transfer switch with load shed kit installed with nema 3R aluminum 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 DC2 controller works with the included transfer switch to automatically provide power during an outage. It includes a four button operator interface with an LCD display and LED indicators. The display provides a scrolling system status that includes eight functions that include generator status, voltage and frequency, and maintenance reminders. More than seventy diagnostic messages for the engine, alternator, transfer switch, load control module and programmable interface module are available on the display. The included Ethernet port allows use of Kohler's On Cue software for monitoring and controlling the generator.
The 20RESAL-SA7 has a polymer enclosure that dampens sound and won't rust or corrode, even in harsh environments. The unit is 48 inches wide, 26 inches wide and 29 inches high. The top of the enclosure is a hinged, lockable cover for easy access to the controller. Under the lockable cover is a second lid that lifts for access to the oil dipstick and filler, oil filter and other generator parts. The 69 dB sound rating compares to the amount of noise made by many central air conditioning units.

I wanted the non-metal housing since I live near the ocean! Included base makes the install easier; unit has plenty of power and included air conditioner relays in transfer switch. Saved $ eliminating the need for additional load shed modules.

Quiet running unit, I like the rust-free materials the base and outer cover are made of. So many times you find the older house generator units are half rusted out after 5-10 years. People should protect any investment worth this much and install a good mounting base that won't hold water. I am overall pleased with the Kohler Unit.

I had my new Kohler generator in stalled last year and what a relief it was. When the power went out my Kohler generator kick rite into action in seconds my power was back on. The power was out for three days and it never miss a beat. Thanks Kohler & Norwall PowerSystems
