Photovoltaic inverters are the core equipment in photovoltaic power generation systems. Their main function is to convert the direct current (DC) generated by solar panels into alternating current (AC) that meets the requirements of the power grid, for use by households, businesses, or integration into the grid. The inverter efficiently converts DC power into high-frequency AC power through the on/off of power electronic switches (such as IGBT, MOSFET, etc.), and processes it through a filtering circuit to output stable sine wave AC power, ensuring efficient conversion and output quality of electrical energy.
