Controller about solar street light price
The controller about the price of solar street light knows:
The main function of solar street lamp charge and discharge controller is to protect the battery. Basic functions include over-charge protection, over-discharge protection, light control, time control, anti-reverse connection, charging trickle protection, under-voltage protection, waterproof protection, etc.
1) Device selection
In the selection of devices, there are currently microcontrollers and comparators. There are many schemes, each with its own characteristics and advantages. The corresponding scheme should be selected according to the needs of the customer group, which will not be detailed here.
2) Surface treatment
Solar street light series products adopt new electrostatic coating technology, mainly based on FP professional building material coatings, which can meet customers' requirements for product surface color and environmental harmony. At the same time, the products have high self-cleaning, strong corrosion resistance and aging resistance. Any climate environment. The processing technology is designed to be coated on the basis of hot-dip zinc, which greatly improves the product performance and meets the strict requirements of AAMA2605.2005. Other indicators have reached or exceeded the relevant requirements of GB.
3) Charging Trickle Protection
When Li Wei solar street light battery panel charges the battery, after the battery reaches the peak voltage, if the battery continues to be charged at high voltage, it will easily cause the battery to run out of water or run out of control; if the charging is stopped, the battery cannot be saturated. This controller will step down 1V immediately after charging to the peak voltage, and then enter the trickle charge state, which ensures that the battery can be stabilized to a full state while avoiding loss of water or runaway. Not only the battery, but also the number of times the battery is recharged, and the service life is longer.
