Power it All

Fridge & Freezer

During an outage, your food is the first thing to go. That’s a lot of hard-earned cash out the window. Good news though, a Kohler generator will keep your fridge and freezer running through an outage, keeping your perishables safe.


TV, tablet, computer. These things keep you connected to the world and what you love to do. A Kohler generator will keep them powered and protected from erratic power surges.

Heating & Air Conditioning Systems

Whether it's the dead of winter or the dog days of summer, your heating and cooling systems are what keep your family comfortable and your home protected. Ensure they will remain on with a reliable generator.


Running water is a big deal - you need it for drinking, cleaning and flushing. On the other hand, if it’s running into your basement that’s another kind of big deal - really big. If your home depends on well water or a sump pump, your Kohler generator will keep everything working as it should. That means faucets, toilets, showers, washing machine, sump pump and more.

The power goes out

When the power fails or drops below an acceptable level (brownout), the ATS signals the generator to start. In seconds, the ATS transfers your power from the utility to the generator.

10-Second Response

By the time you read this, your Generac generator will have started and restored power to your home.

No Refueling

Unlike portable generators, Generac generators start and stop automatically with no need to refuel. No extension cords. No worries. No hassle.

Your generator powers your home

Your generator then supplies your home with electricity until the utility power is restored.

Total Reliability

Generac generators endure hundreds of tests (during design and production) before they reach your home. The result is total reliability.

Lasting Power

Inside every Generac generator is a commercial-grade engine built to withstand extreme workloads. We’ll keep your house comfortable as long as the power’s out.
