CHOOSE THE #1 SELLING HOME STANDBY GENERATOR BRAND
Generac’s Guardian Series generators provide the automatic backup power you need to protect your home and family during a power outage. Connected to your existing LP or natural gas fuel supply, it kicks in within seconds of sensing power loss— automatically—and runs for as long as necessary until utility power returns. Choose from just enough power to cover essential circuits, or all the way up to 22 kW for the most power per kilowatt and whole-house coverage.

Lowest Cost Per Kilowatt
Homeowners can invest in a home standby air-cooled generator size that used to only be available in much more expensive, liquid-cooled models, giving them the lowest cost per kilowatt available.
Rated for Operation in Areas with Low Natural Gas Pressure
In areas with low natural gas pressure, the Guardian Series 22 kW generator can operate on natural gas pressures of only 3.5” of water column.

How Does an Automatic Home Backup Generator Work?

A Generac home backup generator senses a power outage, turns on automatically, and delivers backup power to your home. It will run until utility power returns - whether that's two hours or two weeks.

Utility Power Is Lost

Perhaps it's a storm. Maybe it's an equipment failure. In any case, the electricity you depend on is suddenly gone.

STEP 2...

Your Generac Generator Senses A Problem

Within seconds, your generator prepares to restore your home's power.

Step 3...

The Generator Turns On Automatically - Whether You’re Home Or Away

Within a few seconds, it is up to speed and generating electricity.

Step 4...

Your Electricity is Restored
