30kW 30RCL

Exceptionally powerful, surprisingly quiet.

Whatever the size of your home or business, there’s a reliable RCL generator to match. These five models feature robust 1800-rpm liquid-cooled engines and patented technology that keeps sound levels to a minimum. And now there’s a 30-kW model to round out the lineup.

Quality—Backed By a Long Warranty

Every KOHLER® generator is meticulously quality-tested for total reliability. It comes with our 5-year, 2,000-hour limited warranty, plus a corrosion-resistant aluminum enclosure that’s built to last.

Extremely Quiet Operation

Patented technology makes operations and weekly exercise surprisingly quiet and neighborhood-friendly, with sound levels similar to a typical central air conditioner and as quiet as a normal conversation.

Protect Your Electronics

Outstanding voltage and frequency regulation and ultra-low levels of harmonic distortion provide high-quality power that won’t harm sensitive electronics or expensive appliances.

Easier Installation and Maintenance

An easier install means a faster install. A simple terminal block helps streamline your dealer’s installation, and single-side service makes these generators easy to maintain.

Compatible With Advanced Options

Models are equipped with an RDC2 controller to manage both the generator and the transfer switch. The RDC2 is compatible with the Power Relay Module, Programmable Interface Module and OnCue® Plus Generator Management System.
