The photovoltaic system is generally composed of photovoltaic modules, solar controllers, batteries, inverters and loads. Photovoltaic modules convert solar energy into electricity when there is light, and supply power to the load through the solar controller and charge the battery at the same time. When there is no light, the battery pack supplies power to the DC load through the solar controller, and the battery also supplies power to the AC load through the inverter.
