NTC thermal resistor suitable for solar battery control board.SMD Photosensitive sensor

　　The NTC thermistor is used in gold/silver thermal chips, which has the characteristics of high cost performance, high stability, high reliability, small volume, rapid response and other characteristics. These characteristics can make solar cells more stable and efficient.

　　Principles of Solar Energy Controller:

　　The solar panel is a photovoltaic device (the main part is semiconductor material). It generates the current to generate current after light irradiation. Due to the attributes and limitations of materials and light, the current current is also a volatile curve. If the generated current is charged directly into the battery or the load is powered directly, it is easy to cause damage to the battery and load. Severe seriousness. Reduce their life. Therefore, we must first send the current to the solar controller, use a series of special chip circuits to digitize it, and add multi -level charging and discharge protection. Make sure the operation of the battery and load is safe and service life. When supplying the load, it also allows the battery to flow into the solar controller first. After it is adjusted, the current is sent to the load. The purpose of this: first to stabilize the current; the other is to ensure that the battery is not discharged; the third is to monitor and protect the load and battery.
