How to Choose the Right Electric Generator

  Choosing an electric generator can be a confusing process for many people. The options and models available from a wide variety of manufacturers and retail outlets daunt many consumers and deter them from actually choosing and purchasing a generator. This "analysis paralysis" occurs despite a very real desire to obtain the convenience, security, and peace of mind that an electric generator can provide.

  We present the following information in an effort to reduce the complexity of the generator selection process by identifying a few key questions and providing answers that are as simple as the subject matter allows. In no way is the information presented here intended to be an exhaustive treatment of the topic.

  What’s the single most important thing I must consider? Without a doubt, the most crucial piece of information that you need to know is how much electrical power you will need in your specific situation. Nothing will be more disappointing to you than to buy a generator that does not produce adequate power for your needs.

  In order to determine your power requirements, you will need to understand a little about how electricity is measured. It may help to understand electricity flowing through a wire by comparing it to water flowing through a hose. To keep the following explanation from being quite so dry (pun intended,) we will use the water hose analogy.

  The first unit of electrical measurement is one you already know — volts. Your home has appliances that run on one of two voltages, 120 volts or 240 volts. Most lights and small appliances are 120 volt devices and most bigger items (e.g. electric stoves and clothes dryers) are 240 volt devices. In our water hose analogy, volts may be thought of as the pressure of the water in the hose.

  The next electrical term you need to know is amperes, often shortened to amps. Amps are used to measure the flow of electric current. Think of electricity flowing in a wire just as water flows in a hose.

  The final unit of electrical measurement you will need to consider is watts, which should be somewhat familiar to you. Watts ratings are printed on light bulbs; other devices like hair dryers and electric heaters are also defined by their wattage requirements. Watts are a measure of electrical power and are calculated by multiplying volts times amps. In our water hose example, the water coming from the end of the hose, taking into account both pressure (volts) and flow (amps), provides the power (watts) to do the work.

  OK, I know what watts are, but how do I determine how many I need? That’s probably the hardest question of all to answer because there are so many variables to consider. But in the simplest terms possible, follow these steps.

  First, determine what electrical devices you will want to run from the generator and look at the application guide to determine the watts required for each electrical device. (Remember that the guide is just a guide; actual wattage requirements vary significantly among brands and types. The most accurate way to determine the actual power requirements for any given device is to read the label on the device itself or the manual that came with it.)


  Second, look to see if the electrical device you want to run has a starting wattage requirement that is larger than the running wattage requirement. If it does, use the starting wattage requirement.
