  1. What are the difference between pure sine wave inverter and modified sine wave inverter?

A: The output waveform of pure sine wave inverter is as well as, even better than the 220v 50/60Hz electricity, which suitable for all electrical appliances, such as motor, refrigerator, compressor, washing machine, air conditioner etc. in addition, the pure sine wave inverter can supply stable and high quality AC with low EMI (electromagnetic interference), low noise, low THD (total harmonic distortion, less than 3%), it won’t affect the performance and life of load.

The modified sine wave inverter needs lower cost and technology, so it is cheaper .but it can’t load high power inductive load, such as motor, compressor, refrigerator, air conditioner. What’s more, the modified sine wave inverter will make the EMI for the precision equipments and communication equipments. And the THD ≤20%.
