How does a home backup generator work?

A Generac home backup generator senses a power outage, turns on automatically, and delivers backup power to your home. It will run until utility power returns – whether that’s two hours or two weeks.

  1. Power from your utility is LOST: Perhaps it’s a storm. Maybe it’s an equipment failure. In any case, the electricity you depend on is suddenly gone.
  2. Your Generac generator senses a problem: Within seconds, your generator prepares to restore your home’s power.
  3. The generator turns on automatically – whether you are at home or away: Within a few seconds, it is up to speed and generating electricity.
  4. Your electricity is restored: The automatic transfer switch sends generator power to your home. And it will continue until utility power returns.
