With hurricane season in full swing, it’s critical that your home and family are prepared. Along with having an up-to-date hurricane kit & emergency plan, you may also want to consider equipping your home with a whole home generator.

Since 1959, Generac has been the leading brand in whole home generators. The experts at Art Plumbing, Air Conditioning & Electric are here to explain how they work and the benefits of installing a Generac generator in your home.

Generac Whole Home Generator Basics

Also known as backup generators, whole home generators are an excellent way to provide your home with uninterrupted power in the event of an outage. Generac generators work by sensing your home is out of power and automatically turning on its transfer switch to restore power – whether you are home or not. Generac has long been the most popular whole home generator brand across the nation. In fact, their brand accounts for over 70% of total whole home generator sales across the nation!

Generac Components

Though the power generation process may sound complicated, standby generators are actually fairly simple machines and consist of the following components:

Engine And Alternator

Much like your air conditioner, the engine and alternator are protected under a weather-safe box on a concrete pad outside your home. Fuel powers the engine and connects to the alternator, also known as the generating unit, to conduct electricity. This alternating current works the same way as your usual electricity.

Automatic Transfer Switch

More commonly called the ATS, this switch is the inside component of your generator. The switch connects your home’s main breaker to the rest of the generator. The main function of the ATS is to determine whether your home should operate on utility or generator power. If it senses no issue with your electricity, it will continue to operate on utility power. In the event of an outage or other power disruption, it will switch to generator power.

Other Features

Though primarily consisting of two main components, they also have a couple of features to keep them running correctly and safely:

  • Safety Features: When the generator is operating, it becomes isolated from the electric lines to prevent overloads and improve safety for utility workers.
  • Exercise Feature: Once a week, the Generac generator will turn itself on to make sure everything is running properly. This does not activate the ATS.

Whole Home Generator FAQs

Now you know how Generac generators work, here are some answers to frequently asked question we get:

Q: How Long Does It Take To Turn On?

Your generator will take a few seconds after an outage to make sure it’s not just a surge. Your home will have power in just a few moments!

Q: How Loud Is The Generator?

Whole home generators must not exceed a certain decibel by law. Your Generac generator will be quieter than your vacuum cleaner!

Q: Can I Install The Generac Whole Home Standby Generator Myself?

NO! You should always contact a professional, such as those at Art Plumbing, Air Conditioning & Electric. Not only is this the best way to ensure your generator is installed correctly, but it also keeps you and your home safe.
