Sizing Guide for a Home Standby Generators

We rely heavily on electricity to power the things that get us by on a day to day basis so there may come a time when you’ll need an alternative source. If you’re thinking of getting a generator, one very important question you must ask yourself is ‘what size generator do I need?’ Generators come in a wide range of sizes and are capable of powering up different things. As you can expect, the bigger the size the higher the price so before you go out and blow all of your dollars on a generator, you should determine what size would be most suitable for your needs.

Home Standby Generators were recently dubbed the “Next Must-Have Appliance” for the home. These technologically advanced machines protect homes and families by supplying power that keeps the lights on, the air conditioner or furnace running, and food in the refrigerator and freezer safe from spoilage. They power sump pumps, medical equipment, computers, lights, and kitchen appliances.

A power outage is detected the moment it happens and the generator automatically starts. After a few seconds to reach operating speed, the automatic transfer switch isolates the home from the utility and connects it to the generator which protects both your home and the utility from unexpected line hazards. In just seconds, power is restored and life goes on uninterrupted.

Choosing the right generator is important, and the first step determines how much power you actually need. Too small a unit may not handle a central air conditioner and keep the pumps running that keep your basement dry. Using too large of a generator is inefficient and wastes fuel.

Generators are rated in watts or in kilowatts(kW). 1000 watts equals one kilowatt. Appliances are often rated in amps, amperes, volt-amperes or sometimes watts and kilowatts. Deciding which electrical circuits and appliances to power in an emergency is the first step to sizing a standby generator for your home.
