Consider The Fuel Source

When you are choosing your home generator the first and most important consideration will be the fuel source. This is the fuel source in which your generator will operate off of. If you are in a coastal or remote part of the country there is a good chance that you won’t have access to natural gas. This means that you will only be left with the option of diesel or liquid propane. Unfortunately, going with liquid propane or diesel generators will mean that you will be required to install a large tank in your yard where the gas will be stored. If you already have liquid propane appliances, you will already have one of these tanks. Natural gas will by far be your best option if it is available to you because you don’t have to worry about getting the tank refilled.

Size Of The Generator

Size is another extremely important consideration. You want to make sure that the generator is capable of powering all the items that you want to be powered. First, you will have to consider the appliances that you want to be powered and look at the data plate of each appliance. Look for the wattage draw and the amperage of the appliances. You will then want to use this formula to calculate the kilowatts of the generator that you are going to need. (Starting Amps x Volts =Watts. When you are choosing your home generator, you want to make sure that you are choosing one that offers a 20 to 25% higher peak load than what your appliances require. For instance, if your appliances require 22 kilowatts, you will want to choose a generator that is capable of handling 27 kilowatts.

As for air conditioning systems, you will want to look at the ton rating of the unit and multiply that number by 12,000. (Ton of unit x 12,000). So, if you have a 5-ton heating and air system this means that you will need a generator that is capable of handling 60,000 BTUs or more. Homeowners looking for an entry-level whole home generator should opt for a 22-kilowatt generator. A 27 to the 48-kilowatt generator will be capable of replacing 75% of the 200 amps that come through your electrical panel.
