Power outages can happen at any time — whether caused by storms, grid failures, or unexpected equipment issues.

A whole-home generator ensures your home stays safe, comfortable, and fully functional, even when the main power supply goes down. These systems automatically restore power within seconds, protecting your appliances, preventing disruptions, and providing peace of mind year-round.

What Is a Whole-Home Generator?

A whole-home generator (also called a standby generator) is a permanently installed backup power system connected directly to your home’s electrical panel. Unlike portable generators, it turns on automatically during an outage and can power your entire home or specific essential circuits.

These generators typically run on natural gas or propane, making them reliable during extended outages.

How Whole-Home Generators Work

  1. Power Outage Occurs
    The automatic transfer switch detects the loss of utility power.

  2. Generator Starts Automatically
    Within seconds, the generator activates and begins producing electricity.

  3. Power Restores to Your Home
    The system seamlessly switches your home from grid power to generator power.

  4. Utility Power Returns
    The transfer switch safely switches back, and the generator shuts off.

This automated system ensures uninterrupted comfort and safety.
