What is Inverter Capacity?

Inverter capacity, also known as power handling capacity, refers to the maximum amount of power an inverter can handle and convert into usable AC electricity. In the case of a 5 kW inverter, it means that the inverter can handle up to 5 kW of DC power from the solar panels and convert it into AC electricity.

The inverter’s capacity is typically measured in watts (W) or kilowatts (kW), with higher capacities indicating more powerful inverters. However, it’s essential to note that inverter capacity is not the same as the total power output of the solar panel system.

How is Inverter Capacity Calculated?

The calculation of inverter capacity is relatively straightforward. It’s based on the total DC power output of the solar panels, which is then divided by the inverter’s efficiency rating. The efficiency rating, also known as the power conversion efficiency (PCE), is a measure of how efficiently the inverter converts DC power into AC power.

For example, if a solar panel system produces 10 kW of DC power and the inverter has an efficiency rating of 95%, the inverter’s capacity would be:

DC Power Output (kW) Efficiency Rating (%) Inverter Capacity (kW)
10 kW 95% 9.5 kW
