Enter the inverter power consumption (watts) and the total time of usage (min) into the calculator to determine the Inverter Energy. 

Inverter Energy Formula

The following equation is used to calculate the Inverter Energy. 

IE = PI * T * 60


  • Where IE is the Inverter Energy (Joules)
  • PI is the inverter power consumption (watts) 
  • T is the total time of usage (min) 

To calculate the inverter energy, multiply the inverter power by the time.

How to Calculate Inverter Energy?

The following two example problems outline the steps and information needed in order to calculate the Inverter Energy.

Example Problem #1:

  1. First, determine the inverter power consumption (watts). In this example, the inverter power consumption (watts) is measured to be 7.
  2. Next, determine the total time of usage (min). For this problem, the total time of usage (min) is calculated to be 30.
  3. Finally, calculate the Inverter Energy using the formula above: 

IE = PI * T * 60

Inserting the values from above and solving the equation with the imputed values gives: 

IE = 7* 30 *60 = 12600 (Joules)

Example Problem #2: 

Using the same process as example problem 1, we first define the needed variables outlined by the formula. In this case, the values are provide as: 

inverter power consumption (watts) = 10

total time of usage (min) = 4

Entering these values into the formula or calculator above gives us: 

IE = 4 * 10 *60 = 2400 (Joules)
