How an Automatic Standby Generator Works: Power Without Lifting a Finger
When the lights go out, an automatic standby generator makes sure your home stays powered—without you lifting a finger. But what exactly makes this system work so seamlessly? It all comes down to the unsung hero: the automatic transfer switch.
The Brains Behind the Operation: The Transfer Switch
At the heart of every standby generator system is the automatic transfer switch (ATS). This device is constantly monitoring your utility grid power, 24/7. The moment it senses a power outage, it sends a signal to your generator to start up.
But it doesn’t stop there.
Once the generator fires up, the ATS keeps a close eye on the voltage and frequency coming from it. As soon as those readings are stable and within spec, the switch automatically transfers your home’s electrical load over to the generator. In just seconds, your home is back online—powered by a reliable backup source.
What Happens When Power Comes Back?
Once the utility power is restored, the ATS doesn’t just jump back. It waits. It confirms that the grid voltage and frequency are stable and reliable. Only then does it safely transfer your home back to utility power. At that point, the switch tells your generator to begin its cool-down cycle and shut off.
All of this happens automatically. No extension cords, no manual switches, and no scrambling in the dark.
Safety First
One of the most critical jobs of the transfer switch is isolation. It ensures that your generator never sends power back into the utility lines—protecting utility workers and preventing dangerous backfeeds. This automatic separation is what makes standby systems so safe and code-compliant.
Low Maintenance, High Reliability
These systems are built to be dependable and worry-free. Like any engine-driven equipment, they do require routine maintenance—typically once a year. That’s why we offer flexible maintenance plans, including our Gold, Silver, and Platinum service options, which cover everything from inspections to priority service and discounted parts.
