How do Whole House Generators Work?

Whole house (standby) generators can supply power to a home or building in the event of a power outage. Unlike portable generators, whole house generators are started automatically when they detect a disruption in power. These generators are typically powered by natural gas or propane. The process looks like this:

1. Detection of Power Loss

Whole house generator constantly monitor incoming voltage from the local power grid. If the system’s automatic transfer switch detects an outage, it will notify the generator that power is needed.

2. Generator Start-up:

The generator will start up automatically within a few seconds of an outage. There is typically a short disruption of electricit while the systems gives the grid an opportunity to restore power.

3. Power Supply to Home/Building:

After the generator has started, electricity is routed through the home’s electrical system. Most generators will supply enough power to support all of your major appliances including your heating and cooling system, for hours, or days. There are many types of systems and options to suit your needs.

4. Automatic Shutdown

The system will monitor power coming from the electrical grid. When the utility service has restored electricity, the generator will automatically shut down.

Benefits of Whole House Generators

Standby generators can cost between $4000 and $25000. This includes the installation cost. The bigger the home, and the more power you’d like to have available, the more you can expect the system to cost. While this is a large investment, the comfort and benefits provided by backup power are significant.

  • Enjoy uninterrupted power during an outage.
  • Ensure HVAC systems, medical equipment etc. have electricity.
  • Maintain safety and security during prolonged disruptions.
  • Avoid pipe bursts during winter outages.
  • Sump pumps remain operational during storms.
  • Refrigerators stay powered, so no food will spoil.
  • Retain the ability to communicate via phones, internet etc.

Whole house generators reduce safety and security risks. They allow you to maintain absolute comfort during a power outage. If you’d like to learn more about these systems, get in touch for a free estimate and consultation.
