How does a Standby Generator work?
When the power goes out, life at home can come to a standstill—lights go dark, food in the fridge is at risk, and heating or cooling systems shut off. A standby generator eliminates that worry by automatically restoring electricity within seconds. Unlike portable units, a standby generator is permanently installed, connected to your home’s electrical system, and powered by natural gas or propane. It’s designed to keep your home running smoothly, no matter how long the outage lasts.
Automatic monitoring
A standby generator is always on guard, connected to your home’s electrical system and monitoring the utility power. The moment the power goes out, it detects the outage within seconds.
Automatic Transfer Switch (ATS)
The generator works with an Automatic Transfer Switch. This switch disconnects your home from the utility grid during an outage and safely connects it to generator power.
Fast start-up
Within seconds of detecting a power loss, the generator’s engine starts automatically. Unlike portable generators, there’s no need to refuel or manually start it.
Continuous power supply
The generator begins producing electricity right away, sending power directly to your home’s electrical panel. Essential systems like lights, heating/cooling, refrigerators, sump pumps, and medical devices stay on without interruption.
Fuel source
Standby generators typically run on natural gas or propane, connected to your home’s fuel supply. This ensures a continuous, reliable energy source—no need to store gasoline or refuel by hand.
Automatic shutoff when power returns
Once utility power is restored, the Automatic Transfer Switch safely shifts your home back to grid power. The generator then powers down and returns to standby mode, ready for the next outage.
Self-testing & reliability
Most modern standby generators perform weekly or bi-weekly self-tests. They automatically run briefly to ensure everything is in working order, giving you peace of mind that your system is ready when you need it.
Seamless operation
The entire process—from detecting an outage, to powering your home, to switching back—happens automatically. You don’t even need to be at home for your standby generator to protect you.
