The wind solar system is composed of a solar cell group, a solar controller, and a battery (group). If the output power is AC 220V or 110V, an inverter is also required. The functions of each part of the wind solar system are
The classification of inverters is conducive to off grid wind solar system designers and users to identify and select inverters. In fact, inverters with the same waveform are still very different in terms of circuit principle, use of devices and control methods.
