Control Your Power.
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. Now coming with FREE Mobile Link™, allowing you to monitor the status of your generator on a phone, tablet or computer from anywhere in the world. How It Works
Mobile Link™ Remote Monitoring FREE with every Guardian Series Home Standby Generator
Allows you to monitor the status of your generator from anywhere in the world using a smartphone, tablet, or PC. Easily access information, such as the current operating status and maintenance alerts. With Mobile Link, you are taken care of before the next power outage.
Automatic Operation
Don't worry about having to be there to start and turn off 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.
