Low frequency inverter is the inverter type derived from the classification of the output frequency, pure sine wave inverter is the inverter type derived from the classification of the output waveform. The two are partially overlapped (ie, cross-relation). So there is no way to tell the difference between them.
Low frequency inverter can be divided into pure sine wave low frequency inverter, modified sine wave low frequency inverter and square wave low frequency inverter according to the output waveform. Pure sine wave inverter can be divided into low frequency pure sine wave inverter and high frequency pure sine wave inverter according to the output frequency. Compared with high-frequency inverter, low frequency inverter has greater peak power capacity and higher reliability. Pure sine wave inverter outputs clean, smooth, quiet and reliable pure sine wave alternating current, which can load all electronic equipment that the grid can load without causing damage to the electronic equipment and the inverter. This is not possible with inverters of other waveforms. In general, if the economy permits, we recommend that you choose a low frequency pure sine wave inverter.
