What's a home generator?

A standby home generator keeps your power on during an outage. It’s installed outside your house (like an AC unit) and comes on automatically — whether you’re home or away. All within seconds of a power outage.

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.

Kohler Generators

Keep the lights on through a power outage with a Standby Generator from Kohler.

Kohler Generators are incredibly powerful Standby Generators.

Before the power goes out

Your automatic transfer switch (ATS) monitors the electricity coming from the utility. It's working 24/7 to protect your home.

Power Indicator

This handy little device is located on your automatic transfer switch. It tells you where your home’s power is coming from — utility or generator.

Weekly Self-Test

Your Kohler generator will automatically exercise itself and run diagnostic tests for 20 minutes each week to make sure it’s ready when needed.

OnCue System

With OnCue Generator Management System, you can manage your Kohler home generator, receive updates via text or e-mail, and view real-time power operation and more. All from your computer, phone or tablet.

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 Kohler generator will have started and restored power to your home.

No Refueling

Unlike portable generators, KOHLER 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

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


With PowerBoost Technology, Kohler generators can handle large starting loads like central air conditioners without dropping power to other appliances.

Lasting Power

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