How Generators Are Sized

Here, we will also share the facts and the expert opinion. Mainly, the generator’s capacity and power depend on the generator’s watt. So, if you select the wrong generator size with less or more watts, you will not get the proper aid from the generator.

If you choose fewer watts than the housing requirement, you will not be able to do all the tasks. At the same time, using a larger size of generator is a waste of energy and money for a small house.

For instance, a 2000 square feet home will require a smaller generator than a 2500 or 3000 square feet home. It happens because a smaller generator will have less space and fewer appliances.

Also, it would help if you considered the generator’s actual and starting wattage capacity. It is crucial because actual and starting wattage are two various sizes charting for the machine. Also, it’s the actual capacity of the generator that will run the home appliances.

  • Starting wattage refers to the power the machine will generate when you start it.
  • The actual wattage refers to the delivery capacity of the generator when it is in full operation.

Generally, a generator will have 1000W to 2500W of starting power than its actual power capacity. It will depend on the machine’s size. Henceforth, it would help if you looked at both the starting and actual wattage of the generator to find its actual size. Knowing how many appliances it can run safely will also be useful.

So, go through our in-depth research and find the best generator. Surely, these two generator recommendations will be useful for 1500 to 2500 square feet homes during power cuts.
