Efficiency of Inverters The efficiency of an inverter indicates how much DC power is converted to AC power. Some of the power can be lost as heat, and also some stand-by power is consumed for keeping the inverter in powered mode. The general efficiency formula is: where P AC is AC power output in watts and P DC is DC power input in watts.
where P AC is AC power output in watts and P DC is DC power input in watts. High quality sine wave inverters are rated at 90-95% efficiency. Lower quality modified sine wave inverters are less efficient - 75-85%. High frequency inverters are usually more efficient than low-frequency. Inverter efficiency depends on inverter load. Figure 11.8.
So less energy is output than is input. In fact, inverter efficiency can vary dramatically between products, on average it is between 85% and 95%. For example, if you have an inverter with 85% efficiency it means only 85% of your battery power is being sent to your appliances. The other 15% is lost/used up in the inverter.
Use a wattmeter to measure the power supplied to the inverter from the DC source. 3. Why is inverter efficiency important? Higher efficiency means more of the input power is converted to usable output power, leading to cost savings and better performance. 4. Can inverter efficiency change over time?
