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.
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.
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
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.
