Here had many ways to describe the inverter performance parameter and technology condition,now let’s a brief description talk the inverter general performance parameter.

1.The largest harmonic content of inverter,pure sine wave inverter,under the impedance load,the maximum harmonic content output should be ≤10%.

2.The overload capacity of the inverter: under prescribed conditions,in a relatively short period of time,the inverter output exceeds the ability of the rated current value.Inverter overload capacity should meet certain requirements,under the specified load power factor.

3.The efficiency of the inverter: under the rated output voltage,output current and the load of power factor,the ratio of output active power to input active power (or DC power).

4.The load power factor: allowable variation range of the inverter’s load power factor is recommended 0.7-1.0.

5.The asymmetry of the load: under 10% of the asymmetric load,the asymmetry of output voltage of the three-phase inverter with fixed frequency should be less than 10%.

6.The asymmetric degree of output voltage: under normal working conditions,each load is symmetrical,the asymmetric degree of output voltage should be less than 5%.
