Photovoltaic power generation inverter isolation transformer

Product Overview：

Photovoltaic power generation inverter isolation transformer is a technology that directly converts light energy into electrical energy by using the photogenerated volt effect at the semiconductor interface. The key element of this technology is the solar cell. Solar cells can be encapsulated and protected in series to form large-area solar cell modules. Combined with the power controller and other components, a photovoltaic power generation device is formed.

Photovoltaic transformers are generally used for solar inverters. Because the photovoltaic transformer itself has low photoelectric efficiency. Therefore, the high efficiency of the transformer is especially required.
