Precautions for choosing remote access to network control charger

(Summary description)The main function of the remote access to network control charger in the solar photovoltaic system is to prevent the photovoltaic array from overcharging the battery pack and the battery's over-discharge protection function to the load.

Information

The main function of the remote access to network control charger in the solar photovoltaic system is to prevent the photovoltaic array from overcharging the battery pack and the battery's over-discharge protection function to the load. In addition to these, remote access to network control charger also has some battery maintenance and management functions. Temperature compensation of battery charging voltage, overvoltage and undervoltage shutdown and recovery point setting and adjustment, system warning and remote monitoring functions, system operation parameter recording and other functions.

network control charger

One: You should choose a controller with lower power consumption. The remote access to network control charger works uninterrupted 24 hours a day. If its own power consumption is large, it will consume part of the power. It is best to choose a power consumption below 1 mA Controller.

Two: To choose a controller with high charging efficiency, it is best to have an MCT charging mode controller (maximum current tracking), which can automatically track the maximum current of the battery panel, especially in winter or when the light is insufficient, the MCT charging mode is better than other About 20% higher efficiency.

Three: You should choose a remote access to network control charger with two channels of power regulation, because the controller with two channels of power regulation has been widely promoted. When there are few pedestrians at night, one lighting or two lighting can be automatically turned off during the time. It can greatly save the power of the battery, and can also save electricity, and it can also automatically adjust the power of the LED lamp.

Unless you choose the above power saving function, you should also pay attention to the protection function of the remote access to network control charger to the battery and other components, just like the solar controller in trickle charging mode, which can protect the battery well, thereby increasing To improve the service life of the battery, when setting the controller under-voltage protection value, try to adjust the under-voltage protection value to ≥ 11.1V to prevent over-discharge of the battery.
