Kohler RCA Generators are built in the USA with Heavy Duty Command Pro Commercial V-Twin Engines for exceptional starting power and reliability in any weather including hurricanes. When the power goes out, the 20RCA restores power in 10 seconds to keep appliances working and the lights on. Award winning Kohler Generators provide high quality power and powerful performance for homes and businesses.

PowerBoost Technology starts large loads including central air conditioners while it maintains power to other appliances. The 20RCA boasts an extraordinary 41kVA of motor starting capability. Premium quality power with exceptional voltage and frequency regulation and very low harmonic distortion.

Kohler designed and tested the Command Pro engine for heavy-duty applications in commercial environments. Hydraulic lifters eliminate break-in periods and valve adjustments. The engine operates at a constant speed regulated to 3600 RPM for 60 hertz AC current.
