CE ISO TUV RoHS solar LED street light 5m 20w

الوصف

Product Advantage:

1.The solar street light system configurations are based on scientific calculation and engineering project experience. They are suitable for areas with annual average peak power sunshine of 4.5hrs per day. Battery capacity is designed for 3 days backup in cloudy or rainy weather.
2. The solar street light system configurations can be customized based on client's specific project requirement and weather condition.
3. The batteries are suggested to be placed in battery box and buried in A underground cement pit. In this way, it can avoid overhigh temperature due to sunshine exposure or too cold weather in Winter, wateproof and theftproof, easy for replacement in late period.
4. The pole patterns are standardized type, practical and economical, which can also be customized as per client's specific requirement.
5. All parts are certified by CE and ROHS certificates, meeting Europe standard.

Working principle:

The solar street light relies on solar energy, which is clean, endless and environment-friendly. The system is mainly composed of solar panel, light source, controller and battery. In daytime, when there is sunshine, the solar panel can convert the solar energy to electric energy and store it in the battery. At night or rainy or cloudy condition, the battery shall supply power for normal lighting. The controller can judge the brightness of daylight and automatically switch on the light. The whole process is operating in completely automatic mode, without human action.

Applications:

1.street lighting
2.park lighting
3.roadway lighting
4.fence lighting
5.pathway lighting
6.campus lighting
7.ramp lighting
8.boat dock lighting
9.sidewalk lighting
*0.remote area lighting
*1.private road lighting
*2.farm & ranch lighting

FAQ:

1.Q:How many cycles full charge&discharge about your battery?
 A: In *0% discharging deepness, it can be cycled for 1,**0 times; in floating charging and discharging status, it can be cycled for ***0~***0 times.
 2.Q:What's the difference between *-phase and *-phase inverter?
A: It is mainly the working voltage difference, *-phase is **0V while *-phase is **0V.
 3.Q:What's the main difference between mono and polycrystalline solar panel?
A: production process and cost. Polysilicon technology is more mature since it is an early technology compared with Monosilicon.
 4.Q:The controller of your solar street light has dual time control function?
A: our solar charge controller is designed with dual time control function, you can set up the lighting time and divide it into two parts, like *0 hours (6 hours full power lighting + 4 hours half power lighting)
