The controller is microcomputer intelligent control. The photovoltaic controller has overcharge and over discharge functions, output short circuit protection,

light control and time control functions, and is tested by the indicators of the Industrial Product Quality Supervision and Inspection Center of the Ministry of 

Information Industry.With constant current, soft start, half power, reverse connection, lightning protection, temperature compensation and other protection 

functions. It is marked with charging, over-discharging,load, display indicator, and the cable is made of national standard 4.0 mm2 wire.

    The battery buried box is a special underground buried box for solar street lamps. It has waterproof and cold protection measures, which can effectively resist 

the damage of the rainwater and low temperature to the battery. It is the battery operating in the normal range. 

    The battery is sealed with a maintenance-free lead-acid battery 120AH, which is installed in the ground. It has strong cycle endurance and long service life. The 

quality guarantee period is 3 years and the actual service life is more than 8 years. Self-discharge is small and charging efficiency is high.

    The internal resistance and self-discharge are small, and the current discharge characteristics are good. The temperature range is wide, between -30 and 45 degrees. 

Environmental protection,sealing technology is safe and reliable.

    The solar pole technology requires a cone pole 6 meters high, a lamp arm length of 1.3-1.35 meters, and a lamp head 6 meters above the ground. The main rod is 

made of high-quality steel pipe,the welding rod is smooth, neat and burr-free, hot-dip galvanized and anti-corrosive, and the surface is sprayed.The life of the pole is 20-25 years.

    The shell is made of heat-dissipating integrated aluminum lamp housing, which has powerful heat dissipation, low heat consumption and low light decay: aluminum-based 

PCB board welding process,light decay is less than 10% in one year, no need to install heat sink for 5 mm small particles, room temperature Working 10H, heat sink 

surface and interface temperature rise ≤ 15 °C. Led light source operating voltage range of DC11V-14V can be used normally, in the range of -25 °C - 50 °C can be used 

normally.

    The LED light source adopts the third-generation LED cold light source, and the efficiency can reach more than 90% compared with the incandescent lamp. At the same 

brightness, the power consumption is only 1/10 of that of an ordinary incandescent lamp, 1/3 of a fluorescent tube, and 1/2 of a low-voltage energy-saving lamp. 

    The effective service life is 5,500 hours. Easy to install, can carry out any power combination. Current limiting protection: IC multi-level current limiting protection is adopted, 

which has high reliability.

    The transparent cover is made of anti-aging EVA resin and TDT composite film with excellent weather resistance. The anodized lead frame has high mechanical strength 

and is resistant to wind, cockroach and anti-corrosion.It can be used in all kinds of complicated and bad weather. The output terminals are sealed and waterproof, high 

reliability and multi-function junction box. Install bypass diodes to effectively prevent hot spot effects and line protection, and easy wiring.

    The solar panel has a power generation efficiency of 15.5%, stable performance, and a lifetime of 30 years of monocrystalline silicon solar panels, in line with international 

standards. It adopts imported high-efficiency solar cells and adopts high-strength,high-low iron ultra-white tempered glass to reduce sunlight reflection.
