30kva Solar Inverter

The working principle of crystalline silicon n / p-type solar cells: when p-type semiconductor and n-type semiconductor are closely connected, p-n junction is formed at the interface between them. When the photocell is illuminated by sunlight, positive and negative charges are accumulated on both sides of the p-n junction, resulting in photovoltage and built-in electric field, which is called "photovoltaic effect". Photovoltaic array converts solar energy into electric energy in the case of illumination, and supplies power to the load through the solar charging and discharging controller, while charging the battery pack; in the case of no illumination, the battery pack supplies power to the DC load through the solar charging and discharging controller, and the battery also supplies power to the independent inverter directly, and supplies current to the AC load through the independent inverter Power supply.
