How it Works

GUARDIAN® Standby Generators are completely automatic, helping to ensure that you remain safe from the negative and potentially harmful effects of power loss.

1. The GUARDIAN 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 GUARDIAN generator supplies electricity to the critical circuits you previously chose to back up.

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.

Why Own a Generator?

Imagine your life without power. The conveniences you enjoy and the essentials you rely on are suddenly gone. No lights, no heat, no air conditioning. No sump pump to keep your basement dry. The food in your refrigerator spoils. But it doesn’t have to be that way.

With a GUARDIAN® Standby Generator, your power will return within seconds of an outage, keeping your home and your family safe and secure. Because it’s fully automatic, your GUARDIAN Standby Generator will produce electricity as soon as it senses a power outage - 24 hours a day, 365 days a year, even if you’re away. Unlike a portable generator, there are no switches to flip, extension cords to plug in or gas tanks to fill. GUARDIAN Automatic Standby Generators are connected to your regular natural gas or propane service, providing you with continued power during an outage of any duration.
