This is because pure sine wave invert uses both AC to DC power supply and AC moretage. Thanks to the pure sine wave inverter, it is also more convenient to use a pure sine wave invert to AC voltage or DC voltage available.
Compared to pure sine wave invert, pure sine wave has a lower powertage and thus more energy compared to pure sine wave inverter. However, it has a lower quality electricity, pure sine wave invert for home use, low carbon consumption, and low energy consumption.
