30-36 kW gaseous-fueled standby generator with Brushless Wound-Field alternator and PowerBoost excitation. Largest CCL series unit for residential and light commercial backup.
The Kohler 36CCL is a 30-36 kW gaseous standby generator and the largest unit in Kohler's CCL series. It features a Brushless Wound-Field alternator with PowerBoost excitation, providing sustained short-circuit capability up to 300% of rated current for 10 seconds. Rated output varies from 30 to 36 kW depending on fuel type and voltage configuration. The unit runs on natural gas or LP propane and is EPA certified for stationary emergency use.
The 36CCL shares the same enclosure platform as the 25CCL and 30CCL, making it the right choice when a site needs maximum output from the CCL form factor before stepping up to the larger KG industrial gaseous series.
The 36CCL is frequently deployed in larger residential installations and small commercial sites across our territory. As the top of the CCL line, it often replaces aging 30-38 kW units. Service patterns are consistent with the rest of the CCL series.

Estimate runtime on this tank
Fuel demand at 75% load
378,000 BTU/hr≈ 378.0 cf/min @ 1,000 BTU/cf
On utility natural gas the runtime is generally unlimited provided the supply line and meter can deliver this BTU/hr at the engine's required inlet pressure (typically 5–14" WC residential, up to 5 psi commercial). Confirm against the OEM's published fuel-pressure spec.

Frequently Asked Questions
What is the standby power rating of the Kohler 36CCL?
The 36CCL is rated 30-36 kW standby at 60 Hz depending on fuel type and voltage configuration. It is the largest unit in Kohler's CCL gaseous series.
What type of alternator does the 36CCL use?
The 36CCL uses a Brushless Wound-Field alternator with PowerBoost excitation. This design delivers sustained short-circuit capability up to 300% of rated current for 10 seconds, which is important for motor-starting loads.
Does the 36CCL run on natural gas or propane?
Both. The 36CCL supports natural gas and LP propane with field-selectable fuel switching, like all CCL-series units.
