What is the main function of solar charge and discharge controller?

Release Time: 2022-07-13

The main function of solar charging and discharging controller is to protect the battery. The basic functions must include overcharge protection, over discharge protection, light control, time control, anti reverse connection, charging trickle protection, undervoltage protection, waterproof protection, etc.

1) Device selection
In the selection of devices, at present, there are single-chip computers and comparators. There are many schemes, each with its own characteristics and advantages. The corresponding scheme should be selected according to the demand characteristics of the customer group, which will not be detailed here.
2) Surface treatment
This series of products adopts new electrostatic coating technology, mainly FP professional building materials coating, which can meet the requirements of customers for the coordination of product surface color and environment. At the same time, the products have high self-cleaning, strong corrosion resistance, aging resistance, and are suitable for any climatic environment. The processing technology is designed to be painted on the basis of hot-dip galvanizing, which greatly improves the product performance and meets the most stringent requirements of aama2605.2005. Other indicators have reached or exceeded the relevant requirements of GB.
3) Charging trickle protection

When Yijia solar panel charges the battery, if the battery continues to charge at high voltage after reaching the peak voltage, it is easy to cause water loss or out of control of the battery; If the battery cannot be saturated when charging is stopped. This controller immediately reduces the voltage by 1V after charging to the peak voltage, and then enters the trickle charging state, which ensures that the battery can be stabilized in a full state, while avoiding water loss or out of control. It is similar to circulating charging the battery, which not only effectively protects the battery, but also improves the charging times of the battery and has a longer service life.
