If your home operates on solar or wind energy, or if your community is subject to frequent power blackouts during storms, it’s in your best interest to yamaha generator dealers a back-up generator. How Many Appliances Can a 5000-Watt Generator Run? Can a Generator Run an AC Window Unit? What Appliances Can Be Connected to a Portable Generator?
Generators with large outputs cost more than those with small ones, so sizing your generator involves balancing cost with power requirements. A 5000-watt generator can handle most of the appliances in an average house, but not all at once. In order to determine how many of your appliances you can plug into a 5,000-watt generator, you need to know the power requirements of each one. This information is supplied on the specifications label affixed near each appliance’s power cord.
The requirements are usually listed in watts, but sometimes you’ll only find the current draw in amps. To convert to watts, multiply the amperage by the voltage at which the appliance operates, which is either 120 or 240 volts. Appliances that cycle on and off, such as the refrigerator, require extra power to start up. This extra power can be three times the running power or more.
For example, a refrigerator that only draws 600 watts when it’s on may require 2,200 watts to start. It’s important to take this extra power into account when determining how many appliances to plug into the generator. If you don’t, the generator circuit breaker will trip each time the power draw exceeds its rating. Once you’ve determined which appliances you want to plug into the generator, add up the wattages, being sure to use the start-up wattages when applicable.
If the total comes to less than 5,000 watts, you won’t overload the generator. If the total is more than the generator can handle, you may still be able to plug in all the appliances, as long as the ones you are using at any one time draw less than 5,000 watts. If you’re using a generator to supply emergency power in the winter, you’ll probably want it to operate your furnace. Depending on the size of the fan motor, it may need as much as 2,350 watts to cycle on. If you also plug in a refrigerator, which typically requires 2,200 watts to cycle on, there should be enough power left in the generator to handle a television or radio, a few lights and some small appliances, such as a blender.
