Solar street lamp whose main function is illumination uses high-efficient solar mono (poly)-crystalline silicon cell for the supply of energy, and takes sealed maintenance-free lead-and-acid batteries for energy storing. Its light source is high efficient energy-saving lamp and its charging and discharging is controlled without the participation of human-beings, which is convenient to install and providing stable energy. The solar module can offer direct current and needs no wire or cable, which makes it energy-saving, environment-protecting, economical, practical(it can work consecutive 3~7 rainy days) and long-life(the solar module can be used for 15~20 years, and the battery can work 5~7 years). All the advantages make it the ideal outdoor illumination in the future.
Design characteristics:
1. Use high-performance and power-saving microprocessor-controlling technology;
2. Use rapid charging and floating charging technology, and make full use of solar energy to recharge batteries;
3. Use low-loss, long-life MOSFET FET controller as the main switching device;
4. With a variety of protecting features, including solar batteries and anti-access, battery, battery opening, and protect the storage battery from over charging or discharging, load with over voltage or current and protects from inverted charging at night;
5. Use the charging and discharging curves of the battery to eliminate the inaccuracy of releasing over discharging;
6. Have the function of temperature-compensation.
7. The largest power consumption of controller does not exceed 1% of nominal charge current
8. The voltage drop through the controller system when charging or discharging does not exceed 5% of the rated system voltage.
9. When the battery is unloaded, the controller can undertake more than 1.25 times that of the open circuit voltage shock within 1 hour.
10. It has optional wireless or wired telecommunication function, being easy to monitor and control.
11. Voltage classes: DC12V/24V, AC110V/220V.
12. Spurted with special plastic; Anti-water/moisture.
