Enter the inverter input power and the inverter output power into the calculator to determine the Inverter Efficiency. 

Inverter Efficiency Formula

The following formula is used to calculate the Inverter Efficiency. 

Einverter = IOP / IIP *100

  • Where Einverter is the Inverter Efficiency (%)
  • IOP is the inverter input power 
  • IIP is the inverter output power 

How to Calculate Inverter Efficiency?

The following two example problems outline how to calculate the Inverter Efficiency.

Example Problem #1:

  1. First, determine the inverter input power. In this example, the inverter input power is given as 300.
  2. Next, determine the inverter output power. For this problem, the inverter output power is given as 140.
  3. Finally, calculate the Inverter Efficiency using the equation above: 

Einverter = IOP / IIP *100

Inserting the values from above and solving the equation: 

Einverter = 140 / 300 *100 = 46.66 (%)

Example Problem #2: 

Using the same process as above, first define the variables required by the formula. In this case, these values are:

inverter input power = 400

inverter output power = 200

Entering these values yields:

Einverter = IOP / IIP *100 = 50 (%)
