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 

To calculate the inverter efficiency, divide the inverter input power by the inverter output power, then multiply by 100.

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 (%)

FAQ

What factors can affect inverter efficiency?

Inverter efficiency can be affected by several factors including the quality of the components used, the design of the inverter, the load conditions, the temperature at which the inverter operates, and the frequency of the input power. Efficiency tends to decrease with increased load and temperature.

How can I improve the efficiency of my inverter?

Improving inverter efficiency can be achieved by ensuring the inverter is properly sized for the application, maintaining optimal operating conditions, using high-quality components, and minimizing losses through efficient design. Additionally, keeping the inverter clean and well-ventilated can prevent overheating and loss of efficiency.

Why is inverter efficiency important?

Inverter efficiency is crucial because it determines how much input power is converted to output power, affecting the overall performance and energy consumption of the system. High efficiency means less energy is wasted, leading to lower operating costs and a reduced environmental impact.
