Reliable Home Standby Power
Kohler 14-, 20-, and 26-kW RCA generators offer quiet, reliable performance to power your home.
Commercial-Grade KOHLER Command PRO® Engine
Every KOHLER RCA generator features a heavy-duty engine built to exceed the demands of standby power. The generators are built with hydraulic valve lifters to eliminate need
for lengthy break-in periods and expensive
valve adjustments.
PowerBoost™ Technology
Only Kohler has PowerBoost™ technology which enables our RCA generators to accept heavy loads (like air conditioning or sump pump) without dropping power to other loads in your home. In addition, KOHLER® generators will have your home powered within 10 seconds of an outage.
Easy to Install and Maintain
A simple terminal block helps streamline installation. The RCA line of generators accommodates natural gas fuel pressure
as low as 3.5 inches to eliminate expensive
gas service upgrades.
Get Connected
Connect your generator to the Internet to get peace of mind in the palm of your hand. Whether you’re home or on the go, Kohler’s mobile app will let you monitor your generator system anytime from anywhere and get instant updates via text or email.
Toolless Access in 10 Seconds
The corrosion-resistant enclosure is designed to reduce time required to service the generator. Once the lid is unlocked, in less than 10 seconds you have full access to key components for scheduled maintenance or service. The enclosure is also NFPA 37-compliant to have an 18-inch setback from any structure.
Premium Warranty
You get Kohler’s 2,000-hour, five-year premium limited warranty, covering parts, labor, and dealer travel for the full warranty period. Optional extended warranties are also available.
Blend in or Stand out.
Available Colors
Customize your generator with ten new colors and three camouflage patterns. KOHLER® 14- to 26-kW kW RCA generators can now match your style to complement the color of your home or stand out to make a statement—only available with Kohler.

For a GenWorkX website, a good conversion-focused message would be that generator size should always be determined by a professional load calculation, since square footage alone is not an accurate sizing method. This helps establish expertise while encouraging consultation requests.
