Solar panels are photovoltaic devices (primarily composed of semiconductor materials). When exposed to sunlight, they generate current through the photoelectric effect. Due to the inherent properties and limitations of materials and light, the generated current exhibits a fluctuating curve. Directly charging the battery or supplying power to the load can easily damage both, severely reducing their lifespan. Therefore, the current must first be fed into the solar controller, where a series of dedicated chip circuits digitally regulate it and incorporate multi-level charge/discharge protection. Our company's unique "adaptive three-stage charging mode" control technology ensures the safe operation and extended lifespan of the battery and load. When supplying power to the load, the battery current also flows into the solar controller first, and after its regulation, the current is then sent to the load. This serves three purposes: first, to stabilize the discharge current; second, to prevent over-discharge of the battery; and third, to provide a series of monitoring and protection measures for both the load and the battery.
If AC equipment is to be used, an inverter must be added before the load to convert the AC power.
