With the development of science and technology, the solar charging controller has become an indispensable part of people's life. Its function is to protect the battery charge and discharge very well. The following is a brief introduction by sun Xiaobian of XinDa, introducing the matters needing attention in choosing solar controller.

First, when choosing a solar charging controller, it is best to choose a relatively low power controller, because the controller will work uninterruptedly for 24 hours. If the power is very high, it will greatly consume the power, which is very undesirable. So you need to be careful that choosing a controller with a power consumption of 3 Ma will consume very little power.

Second, the choice of the controller is of course to choose the high charge efficiency, and also need to have a strong charge, balanced charge and floating charge three stage charge control mode. From the current development of the controller, most of the controllers have such a charging control mode.

Third, the non high precision control solar street lamp controller may cause the high repair rate and poor reliability because of the unreasonable design of the product, the poor material material and so on. Therefore, high precision controller is needed. High precision is the comprehensive embodiment of product design. It is also the embodiment of material selection and the embodiment of production technology. High precision controller can ensure product quality, to a certain extent, can reduce maintenance rate and quality.

Fourth, the choice of two ways to carry on the solar charge controller is very good, to facilitate the power adjustment of the lamp, the function can be automatically closed, or two lighting, can better save electricity, and can also adjust the power of the LED lamp. In order to prevent the battery from overrunning, the undervoltage protection value of the solar charging controller can be set to adjust to a voltage greater than 10.8 volts.

As long as you master the above precautions, you can choose a satisfactory solar charging controller. In addition, you can also understand the maximum power point tracking controller, which can track at maximum power point, and it is also a very good choice. If there is anything else we want to know about PV controller, we welcome you to consult XinDa.
