Inverters are mainly divided into three categories according to the waveform, one is pure sine wave inverter, one is modified sine wave inverter, and the other is square wave inverter.

The square wave inverter outputs a square wave alternating current of poor quality, and its positive peak and negative peak are generated almost at the same time, which will damage the load and the inverter. Moreover, the load capacity of the square wave inverter is poor, only about half of the rated power, and it cannot carry inductive loads.

Compared with the square wave inverter, the modified sine wave inverter is slightly improved, and its positive peak and negative peak are no longer generated at the same time, but for a period of time as a buffer. In fact, the modified sine wave inverter still belongs to the category of the square wave inverter, because the waveform it generates is still composed of polylines like the square wave, and the continuity is poor.

The pure sine wave inverter outputs high-quality alternating current, which can drive a variety of loads, and basically no damage to the load and the inverter. Although the cost of pure sine wave inverters is higher than that of square wave inverters and modified sine wave inverters, we still recommend choosing pure sine wave inverters as much as possible.
