How to Calculate the power to buy the right size Genset

It is necessary to calculate the amount of required power to operate appliances with the help of external power resources such as Genset. Here get an idea to calculate the power consumption rate of various devices to run & start.

  • Make a list of all the electrical devices and appliances that you want to run on the generator.
  • For each item that you have taken in your list, note down running power in watts. You can also include the surge power in watts where it is possible.
  • Cannot find the wattage of the item? You have to Calculate the wattage using this simple formula: watts = amps x volts.
  • Now, Add all the running watts. This is the minimum required running power of the generator.
  • After taking the highest value of surge power on the list. Now, it’s important to Add the additional wattage to the total running watts.
  • After all the above steps add a few hundred watts. This needs to be kept in mind that the generator can handle any power fluctuations or additional needs in the future.

How to calculate Run Time of a Generator

We can take the following example. A generator that has 8 hours of run time at a half load. If there is a generator with 2000 watts running power then it can be run for 8 hours when the load is already at 1000 watts.
