What is a home standby generator?

  • Automatic Operation: Unlike portable generators, standby units automatically activate when the power goes out and shut off when power is restored.

  • Connection to Home Systems: These generators are connected to your home’s electrical system and fuel supply, typically natural gas or propane.

  • Power for Essentials or Entire Home: Depending on the model and your needs, standby generators can power specific systems or your entire home.
