Auto start on a generator works by using a sensor to detect a power outage. When the sensor detects a drop in power from the main utility, it sends a signal to the generator's control panel to automatically start the engine. Once the main power is restored, the sensor again detects this change, signaling the generator to stop and switch the power source back to the main utility, ensuring continuous power supply without manual intervention.

FAQs & Answers

  1. What triggers the auto start function on a generator? The auto start function is triggered by a sensor that detects a power outage or drop in voltage from the main utility source.
  2. How does a generator switch back to main power after an outage? Once the main power is restored, the sensor detects this change and signals the generator to stop and switch the power source back to the utility automatically.
  3. Can auto start generators operate without manual intervention? Yes, auto start generators are designed to automatically start and stop based on power availability without any manual intervention.
