Solar street light controller

The main function of the solar charge and discharge controller is to protect the battery. The basic functions must have overcharge protection, over discharge protection, light control, time control, anti-reverse connection, charging turbulence protection, under voltage protection, and waterproof protection.

[2] Battery anti-overcharge, over-discharge protection voltage General parameters:

1) Device selection

In the selection of devices, there are currently using single-chip microcomputers, and there are also comparators. There are many schemes, each with its own characteristics and advantages. The corresponding scheme should be selected according to the customer's demand characteristics, which will not be detailed here.

2) Surface treatment

This series of products adopts new electrostatic coating technology, mainly based on FP professional building materials coatings, which can meet customers' requirements for product surface color and environment coordination. At the same time, the products have high self-cleaning property, strong corrosion resistance and aging resistance. Climate environment. The processing technology is designed to be coated on the basis of hot dip galvanizing, which greatly improves the performance of the product and meets the requirements of the most stringent AAMA2605.2005. Other indicators have met or exceeded the relevant requirements of GB.

3) Charging protection

When the Yijia solar panel charges the battery, if the battery reaches the peak voltage, if the high voltage charging continues, the battery may lose water or run out of control; if the battery is stopped, the battery cannot be saturated. This controller is stepped down by 1V immediately after charging to the peak voltage, and then enters the trickle charge state, ensuring that the battery can be stabilized in a full state, while avoiding water loss or loss of control, similar to circulating the battery, not only efficient The battery is protected, and the number of times the battery is charged is increased, and the service life is longer.
