What does Inverter efficiency really mean?
The efficiency of an inverter refers to how well it converts DC Voltage into AC Voltage. Inverter efficiencies range from 80% up to 95%. The average efficiency is around 90%. However, efficiency ratings can be decreased when using a resistive load such as an incandescent light. When running appliances with motors, the efficiency breaks into 2 parts; the efficiency of the inverter, and the efficiency of the waveform. Waveform efficiency means that the motors and many other electronic appliances run better and use less power with a true or pure sine wave. An appliance with an electric motor, like a pump or refrigerator will on average use 15-20% more power with a modified sine wave inverter compared to when it is run off a true or pure sine wave inverter. When looking at the efficiency rating of an inverter you should also consider what you are going to run. I.e. An 85% efficient modified sine wave inverter is not going to run at 85% when powering a compressor motor. This is due to the f
