First, the composition of solar street light

Solar  street lights from the following components: solar panels, solar  controllers, battery, light source, light pole and lamp housing. If the output power is AC 220V or 110V, but also configure the inverter.

solar panel

    PV module matrix: by the solar module (also known as photovoltaic cell  components) in accordance with the system needs string, in parallel, in  the sunlight will be converted to solar energy output.

Charge controller

    It is the battery charge and discharge conditions to be regulated and  controlled, and in accordance with the load power demand control of  solar modules and batteries to load the power output is the core of the  entire system control part.

Energy storage battery

    Storing the electric energy generated by the solar cell module, and  releasing the stored electric energy to meet the energy demand of the  load when the illumination is insufficient or at night or when the load  demand is greater than that of the solar battery module, which is the  energy storage part of the solar photovoltaic system

light source

    What kind of light source is the use of solar lamps is an important  indicator of the general use of low-pressure solar energy lamps, low  pressure sodium lamp, lamp, DLED light source.

Light pole and lamp housing

The height of the poles should be based on the width of the road, the  distance between the lighting, road illumination standards to determine.

Second, the system works:

1 System wiring diagram:

Design features:  light control + hole, according to the intensity of light during the  day and night to automatically control the lights turn off the lights  requirements can also be set according to time off lights time, Battery, an effective solution to the battery to adapt to the ambient temperature and cycle life,

2. System operating mode

1) Operation of the solar panel

     When  the sunshine during the day, the main input power (solar panels) work,  direct sunlight through the solar panels produce DC power, the charge  controller to adjust, a group of energy storage battery charge, so that  energy storage battery in the floating state , Another group to the inverter power supply, the inverter will convert DC sine wave AC power output, to the load power supply.

2）储能蓄电池运行状态

当晚上没有阳光时，主输入仲博最新版下载（太阳能电池板）没有工作，此时则由储能蓄电池给逆变器供电,由逆变器将直流转换为正弦波交流仲博最新版下载输出,给负载供电.
