What is inverter efficiency and why does it matter?
The efficiency of an inverter determines the amount of AC output power it generates for a given input of DC power. This usually ranges from 85% to 95%, with 90% being about average.
When running such things as motors, the efficiency actually has two parts to it – the efficiency of the inverter, and the efficiency of the waveform. Waveform efficiency means that most motors and many electronic appliances run better and use less power with a sine wave. Typically, an electric motor (such as a pump or refrigerator) will use from 15% to 20% more power with a modified sine wave than with a true sine wave. Thus when choosing an inverter based on efficiency, you should also consider the type of loads being powered to determine true system efficiency.
