Selecting the Correct Generator

Before making a decision about home generators, it's important to calculate emergency power need for house - and even garage and other property - requirements.

Kohler's easy home generator sizing calculator helps you understand the standby power requirements you'll need from your home generator, and will help you determine what type of backup power to expect from various home generators.

How to use Kohler's Home Generator Sizing Calculator

In order to estimate your generator size requirement, please enter the square footage of your home, then select which appliances you would like to run during a power outage.

You may want to experiment by adding or removing significant and occasional appliances to see how it impacts the suggested generator size.
