You must calculate what your maximum amount of power needed will be. Generators are usually chosen based on how much power they produce. If you don't understand the amount of power needed you can choose the wrong system and not have enough power produced to supply function throughout your home or business.

There are some appliances and equipment that require greater volumes of starting wattage and then it tapers off. You should check owner's manuals for your appliances or research what voltage or wattage your appliances or equipment is.

A good tool to help you understand what system you need do the following: Take the running wattage of your appliance and multiply it by three.

Contact a sales representative and talk with them about your needs, size of your home or business and ways you intend on using your generator. They can help you choose the proper type of system; however you can choose a generator on your own after reading and learning about the various types of systems available.
