It is mainly composed of three parts: solar photovoltaic panels, controllers and inverters. The main components are made of electronic components. Solar cells are packaged and protected after being connected in series to form large-area solar cell modules. Combined with power controllers and other components, a photovoltaic power generation device is formed. In order to receive, distribute and control the electrical energy generated by the photovoltaic power generation device and ensure that the electrical energy is safely and stably transmitted to the load, a power cabinet is required for power distribution.
