Features and selection of controllers in solar street lights

　　Solar controller is suitable for solar photovoltaic power generation system, coordinating solar panels and batteries, work load is a very important photovoltaic system component. Make the entire solar photovoltaic system efficient and safe operation.

　　Solar street light controller is mainly used in household, commercial, factory, transportation, communication and other solar power generation systems. Because the solar street light controller should have the following basic characteristics:

　　1) Overload protection

　　2) Short circuit protection

　　3) Reverse discharge protection

　　4) Reverse polarity protection

　　5) Lightning protection

　　6) Voltage protection

　　7) Overcharge protection

　　8) Restore power to the load

　　For the choice of solar street light controller, you should choose a low-power controller. The controller works 24 hours a day, because they consume power and consume a certain amount of energy. It is best to choose a power control less than 1mA .

　　 To choose a high-efficiency charging controller, the MCT charging mode controller can automatically track the maximum current of the solar panel, especially in winter or when the light is insufficient, the MCT charging mode is about 20% higher than the efficiency.

　　 should choose to have a two-way adjustable power controller. The controller has power adjustment and has been widely promoted. At night, there are few pedestrians and can automatically turn off one or two lights to save electricity. You can adjust the power of LED lights. In addition to the power-saving functions selected above, it should also focus on the protection functions of the controller. For example, a controller in trickle charge mode can well protect the battery and other components of the battery and increase the life of the battery. On the other hand, set the control The under-voltage protection value of the device, the transfer of voltage ≥ 11.1V, to prevent the value of battery over-discharge protection.
