HOME BACKUP POWER.

COMFORT. SECURITY. CONVENIENCE.

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.

Automatic Operation

Don’t worry about having to be there to start and stop your Generac home backup generator. Because it does that automatically. Whether you’re home or away.

Refueling Not Necessary

Your Generac home backup generator runs on your existing natural gas or LP fuel supply. Save the gas cans for your other outdoor power equipment.

Power Directly to Your Home

You’ll never have to run an extension cord through a window or door again. Your Generac home backup generator safely delivers power right to your home’s electrical panel.


HOW DOES A HOME BACKUP GENERATOR WORK?

It starts and stops automatically, and never needs refueling.
This video explains how and why.
