How much energy does an inverter use?

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.

What is the efficiency of a sine wave inverter?

Pure sine wave inverters offer between 90% and 95% efficiency. The other option is a modified sine wave inverter which is generally cheaper but is less efficient. These lower-performance products usually have an efficiency of below 90%. It is possible to calculate the efficiency of a power inverter although it can be a little complicated.
