How does a Generac 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 in two hours or two weeks.

A Generac home backup generator is permanently installed to help automatically protect your home in the event of a power outage. The equipment sits outside of your home, much like your central air conditioning unit. It runs on natural gas or liquid propane fuel and delivers power directly to your home’s electrical system. This helps ensure that your entire home or just the most essential systems are backed up during a power outage. With a Genearac home backup generator, you don’t have to worry about going outdoors to start or stop the generator. The Generac home backup generator operates automatically, even while you are away. You’ll also never have to worry about refueling your generator as the Generac home backup generator runs on your home’s existing LP fuel or natural gas supply.

What size generator is needed to run a house?

Determining the appropriate size of generator to run a house involves assessing the total power requirements of essential appliances and devices that would need to be operational during a power outage. Start by compiling a list of these items and calculating their total wattage, considering both their running watts and any additional starting watts they may require. Typical household needs can range from 5,000 to 10,000 watts for basic essentials, but larger homes or those with central air conditioning may require generators with capacities exceeding 10,000 watts.

Can I back up my whole home, or just certain parts of it?

You can choose to backup your entire home or just specific circuits depending on your needs and the capacity of the generator you install. Whole house generators are designed to provide backup power to all essential circuits in your home, including lights, appliances, HVAC systems, and other critical devices. The automatic transfer switch (ATS) allows for seamless switching between utility power and generator power, ensuring that your entire home remains powered during an outage.

Alternatively, you can opt for a partial backup solution by selecting specific circuits to be connected to the generator. This approach allows you to prioritize essential circuits such as refrigerators, sump pumps, heating systems, and select outlets or rooms in your home. This option is often chosen when installing a smaller capacity generator or when focusing on critical areas of the home during power outages.
