Our most popular generators for backup power provide award-winning reliability and performance. When you lose power during an outage or storm, a hard-working 14/20 kW KOHLER® generator keeps your appliances working, the heat or AC running and your security system on. Now also available in 3 phase.*
Every KOHLER® generator is equipped with a heavy-duty, commercial-grade engine that stands up to extreme weather.
In just 10 seconds, your KOHLER generator automatically restores power to a 5-ton (60,000 BTU) air conditioner, major appliances and electronics.*
We've got you covered with 5-year, 2,000-hour protection, and a corrosion-proof enclosure that's built to last.
KOHLER generators have received several awards, including the Most Valuable Product (MVP) Award 2010 by Building Products magazine.
