The Kohler 48RCLC produces 48kW on propane and 48kW on natural gas. It uses a KG6208, 6.2L V8 engine running at 1,800 rpm, with 113kVA of peak motor-starting capability.
The Kohler 48RCLC is intended for large simultaneous loads where the 38RCLC is insufficient, with a 6.2L V8 and substantial installation footprint.

Where the 48RCLC Fits
The Kohler 48RCLC is intended for large simultaneous loads where the 38RCLC is insufficient, with a 6.2L V8 and substantial installation footprint. On natural gas, plan against 48kW rather than the propane nameplate. The 113kVA starting rating describes a short motor-start event and cannot be added to the running output.
Inventory the loads you need during an outage, including HVAC starting current, pumps and electric heat. Use the generator size calculator to organize the load list, then have an installer check the design against the exact alternator and fuel configuration.
Equipment Cost and Installation Scope
Kohler’s starting equipment MSRP for the 48RCLC is $25,703, checked September 30, 2026. That is not an installed price.
A complete quote should itemize the generator, compatible transfer switch, battery, foundation, electrical and fuel work, permits, commissioning, registration and any load controls or cold-weather accessories. Long trenching runs, gas-meter upgrades and changes to service panels can materially change the total. Compare equivalent scopes from local installers; no national installed average is asserted here.

Transfer Switch and Fuel Supply
Budget and specify the automatic transfer switch separately unless the seller explicitly includes a compatible unit in the quoted package. Match switch amperage, service-entrance suitability, number of panels and load management to the installation design. A generator’s kW rating alone does not determine the correct transfer switch.

At full load, the technical sheet lists 875 ft³/hr of natural gas and 315 ft³/hr of LP vapor. Have the installer check fuel supply with the other connected appliances operating; a meter label or short pipe run alone does not establish sufficient capacity.
Ownership and Service
TP-7102 lists oil and filter changes yearly or at 150 operating hours. Check oil every 24 hours or before each day’s operation. Use the complete current manual for air-filter, ignition, battery and other service tasks. Severe conditions may require shorter intervals; match the manual to your model and serial number.
