First: Since the output voltage and power of the solar module are greatly affected by the light, the voltage is high and low, so the solar inverter must adapt to a very wide voltage range. For example, the 3-5kw solar inverter DC input voltage range is 120. -500V, while the general inverter DC voltage range does not exceed +_25%.

Second: In addition, the input voltage of the solar inverter is high and low. In order to ensure high efficiency operation, the maximum power output function is generally tracked automatically, and the ordinary inverter does not need this function.

Third: In order to adapt to the input requirements of multi-channel photovoltaic modules, solar inverters generally have more than 6 DC input terminals, while ordinary inverters do not need so many inputs.
