2. Product Overview

The product introduced here is a three phase photovoltaic transformer with 25KVA rated capacity. Its input voltage is 380V or 400V. Its output voltage is 380V or 400V too. It is mainly used in photovoltaic power generation. The photovoltaic panel collects the direct current, which is transformed into alternative current through an inverter. However, the alternative current transformed through the inverter is not purified. It is full of impurities. Under this circumstance, the three phase isolation transformer would function in eliminating all the impurities and get the alternative current purified. In this way, the alternative current could be connected to the power grid. So three phase isolation transformer is an important part in photovoltaic power generation.
