The #1 selling brand of home backup generators

Generac created the home backup generator category. Today, our generators are preferred by 8 out of every 10 homeowners who invest in home backup power.

A permanently installed Generac home backup generator protects your home automatically. It runs on natural gas or liquid propane (LP) fuel, and sits outside just like a central air conditioning unit. A home backup generator delivers power directly to your home’s electrical system, backing up your entire home or just the most essential items.

With automatic operation and 24/7/365 support from our Wisconsin headquarters, a Generac home backup generator gives you the peace of mind in an increasingly uncertain world.
