Avoid Generator Undersizing

Smaller generators cannot be used for standby power. Generator undersizing is a common and dangerous myth. You run the risk of not only damaging the unit but also damaging other appliances and assets connected to it. This damage can lead to limits overall productivity, decreases the reliability of the generator, and can even create hazardous situations for your home and loved ones.

Knowing the precise power needs of your devices should always your first step. There are so many generators to choose from: single-phase, three-phase, kW, KVA, welder, standby, or motor starting generators. But more power is always better than less. Speak to a certified electrician concerning the power demands of your systems during an official inspection. Make a note of the starting and running wattage of your items and calculate the total power usage in Kilo-volt amps (kVa) or Kilowatts (kw). These notes will help you determine the proper sizing for the generator you need and aid you when it’s time to make your purchase.

Determining Starting & Running Wattage

Determining the starting and running wattage for each of your devices should be an easy task. These values should be clearly labeled on the device’s identification plate, or in the owner’s manual. Often, however, you may find power requirements in amperes, and you will want to convert that number into watts for more precise data. To do this, you can use the following calculations. You can use these numbers to determine each device’s specific consumption needs then match the output of various generators to determine the ideal one for you:

  • Resistive Load Wattage: Take the labeled number of amperes and multiply it by the number of volts.
  • Reactive Load Wattage: Multiply the Restrictive Load Wattage by the labeled Load Factor

Types of Generators

A quick search of backup generators online provides a massive amount of information. Navigating through this mess and finding the best option for your home can be a challenge. Lucky for you, Provident Electric has the knowledge to help you make your decision. The first thing you’ll want to think about is how many items you’ll need to power during an outage and what the common wattage usage will be (see above). If that already sounds too confusing, our professional electricians can help you calculate the wattage usage of your main appliances, lights, and hardwired equipment. Next, you’ll want to match your needs up with an appropriate home generator.

Even smaller models will require the help of an electrician, but here are some main points you’ll want to know about the types of generators available:

  • Portable: Most portable models can power up to 7,500 watts. These generators can be connected to your breaker panel with a transfer switch allowing the ability to run hardwired appliances, like well pumps or small A/C and heating units.
  • Large Inverter: Large inverter models can also power up to 7,500 watts. This type of power generator must be connected to your breaker panel, requiring the help of a professional electrician. This connection allows you to power hardwired equipment and necessities like a furnace or A/C unit.
  • Home Standby: These models are permanently installed next to your house and are usually tied directly to your natural gas supply, eliminating the need to refuel. Most home standby models can power up to 20,000 watts, enough to power the entire home. These generators turn on automatically when a power failure is detected, resulting in uninterrupted power. You won’t have to take the time to wheel a portable model out of the garage, hook it up, or start the engine.
