How backup generators work

Backup generators use advanced technology to keep power flowing to your home in case of a power outage. The systems we offer are stationary, permanently installed devices that resemble an outdoor air conditioning unit. They run on a variety of fuels (natural gas, gasoline, diesel, propane or bio-fuels) and connect directly to your home's wiring.

If your home loses power, your generator will automatically kick in, powering parts of your home or even specific appliances based on the settings you have chosen. The generators we offer vary in capacity — from small generators that power a limited number of essential circuits and appliances to generators that can power every circuit in your home for extended periods of time. They shut off on their own when power is restored.

Why you need a backup generator

Power outages can disrupt your life and even be disastrous if you have critical electric appliances and equipment in your home. A permanently-installed generator can automatically keep your home powered during short or long outages. If you live in an area with frequent storms or outages, you can avoid lengthy hotel stays, sweltering summer days without AC, spoiled food or temporary relocations by installing a generator on your property.

Power outages can occur for a variety of reasons.
