7-18 kW Air-Cooled Automatic Home Standby Generators

Guardian by Generac Power Systems
With a Guardian Automatic Home Standby Generator, your home is protected from power outages whether you're home or away. With five models between 7 and 18 kW, you choose the level of protection that is right for you. Whether you choose to back up a few essential circuits with one of our pre-wired systems or to provide emergency power to the entire house, Generac will keep your family safe and comfortable until utility power is restored.

How it Works
Generac Standby Generators are completely automatic, helping to ensure that your home or business remain safe from the negative and potentially harmful effects of power loss.

1. The Generac system automatically and continuously monitors incoming power from the utility line.

2. When utility power is interrupted, the control system in the generator automatically senses the loss of power and signals the generator to start.

3. The automatic transfer switch safely closes off the utility line and simultaneously opens a new power line from the generator.

4. Your Generac generator supplies electricity to your main distribution panel through an automatic transfer switch. You can elect to back up selected emergency circuits or your entire electrical service.

5. When utility line voltage returns, the system transfers the electrical load back to the utility line. The generator continues to run for an engine cool-down period of several minutes and the entire system stands ready for the next power outage.

To ensure the system is always ready when you need it, your generator will run a 10-12 minute self-test cycle every week.
