Solar charge and discharge controller

The working principle of solar LED street lamp

2.4 Controller

Solar charge and discharge controller's main role is to protect the battery. Basic functions must have overcharge protection, over-discharge protection, light control, time control and anti-reverse and so on.

Anti-battery overcharge, over-discharge protection voltage of the general parameters such as Table 1, when the battery voltage reaches the set value after the change in the state of the circuit.

In selecting the device, there are currently using SCM, and also have use of the comparator, and the program more, have their own characteristics and advantages, should be based on the needs of customer base, characterized by selecting the corresponding program, does not want to elaborate on this.

2.5 Surface Treatment

This series of products using electrostatic coating of new technologies to FP-based paint professional building materials to meet the customer's environment, coordinated colors and surface requirements, while products with high self-cleaning, corrosion resistance strong, anti-aging, applied to any climate and environment. Processing technology is designed on the basis of hot-dip zinc coating, so that product performance has greatly improved AAMA2605.2005 meet the most stringent requirements, other indicators have reached or exceeded the GB of the relevant requirements.

3, Conclusion

Basically, the overall design takes into account all aspects; peak watt PV modules and battery capacity of the number of type design type design using the most common design method is more scientific ideas; wind-resistant design components from the battery bracket and lamp under 2 do an analysis, a more comprehensive; surface treatment using the most advanced technological processes; lights the whole structure is simple and beautiful; through the actual operation proves that a good matching between the various sectors.

At present, solar LED lighting the initial investment that continues to haunt one of our main problems. However, the luminous efficiency solar cells gradually increased and the price will gradually decrease, and likewise LED light effect on the market are improving rapidly, while the price is decreasing. And solar and renewable, clean pollution-free and environmentally friendly energy-saving LED's compared to conventional fossil fuels become increasingly tense, and after use on the environment will cause an increasingly serious pollution. Therefore, solar LED lighting as an ascendant of outdoor lighting, to show to us will be the endless vitality and broad prospects.
