Home Backup Generators

By Ray Hauser


The storm hit suddenly and violently without much warning. Forecasters didn't predict the heavy snow and wind unusual for October even this far north. Within hours, the heavy, wet snow began straining branches and power lines. Trees had yet to shed most of their leaves which captured the snow and multiplied the weight. Loud snaps and cracks could soon be heard reverberating throughout the vicinity as branches came crashing down taking out power lines, rooftops and anything else in their way.

By nightfall, electricity was out in the area and most surrounding neighborhoods. As the icy blast dissipated, an eerie darkness descended upon the storm ravaged area. Candles and flashlights cast fleeting shadows in homes up and down the snow covered streets.

When the power went out in our house, a Generac Guardian standby generator came on within moments and supplied power to dedicated circuits energizing lights, the furnace, refrigerator/freezers along with a few nonessential items such as television sets and computers.

Utility crews worked around the clock to repair the vast number of downed power lines, but some homes went without power for over a week. Rotten food and flooded basements became a hallmark of the area. Some people were actually forced to flee their homes and stay in hotels or move in with relatives.

According to NOAA (National Oceanic and Atmospheric Administration) electrical outages have been growing at over 7% annually costing almost $1.5 billion per year. It pays to have emergency backup power.

The concept of a standby generator system is pretty straightforward. Under normal conditions the local utility supplies electricity to homes in a particular community. The utility gets its power from main generating plants which use coal, oil, natural gas, hydro and nuclear energy to generate electricity by rotating turbines.

A home, standby generating system is comprised of a generator and a transfer switch. The generator itself is powered by an internal combustion engine which runs on propane or natural gas. The generator is installed outside the home generally near the incoming power lines. The transfer switch is located alongside the circuit box inside the house.

When utility power is lost, the standby generator springs to life supplying the necessary power. A transfer switch detects the utility outage and disconnects the home electrical system from the utility network and then connects it to the standby generator. When utility power resumes, the transfer switch disconnects the electrical system from the standby generator and reconnects it to the utility grid. The generator then shuts down and returns to standby mode quietly waiting for the next time it's needed.

The first step in selecting a home, standby generator is to determine how much power you might need, if there is a general utility outage. What devices do you want to operate including lights, furnace, refrigerator/freezer, televisions etc? Most devices are clearly labeled with their wattage ratings, so it's fairly easy to add them up to calculate your total power needs. After a determination is made on how much power is required, it is simply a matter of finding and installing the right size generator.

Authorized Generac dealers have trained technicians who can assist you in finding the right generator to fulfill your standby power needs.
