solar street light controller it's the second generation of the eprc solar street light controller, it provide automatic lighting control function. good for street and pathway lighting, parking area,
it uses a range of wireless connection technologies such as bluetooth or wifi to securely log on to each solar light. additionally, leadsun has incorporated the latest in mesh networking to provide our systems with linkable communication between each solar light system that can be accessed remotely via gprs or 433 technology.
smart street light system with energy saving function based on the sensor network. currently, in the whole world, enormous electric energy is consumed by the street lamps, which are automatically turn on when it becomes dark and automatically turn off when it becomes bright. this is the huge waste of energy in the whole world and should be changed.

solar charge controller user s manual 13 normally. g. then connect the circuit of solar module. if it is daytime, the controller will start to charge the battery and you can check the present charging current and the voltage of solar panels.
dec 20, 2012 and solar system capacity, that will have the reg floating by around 11am. on normal sunny day in q'land. thus giving the exra time of daylight left to top up battery's if cloudy. i always had\have a genny as well though. as my systems won't run aircond.
so, we need a device called solar charge controller to control the current we receive from solar panels, the charge controller has inbuilt pwm (pulse width modulation) charger to charge the lead acid battery in three stages, which ensures long life for battery.
in simple terms the pwm refers to the pulse with modulation feature of the arduino. in the pwm pins the output signal via a pwm pin will be an analog signal ( at least it behaves like one) acquired as a digital signal from the arduino .it uses the duty cycle of the digital wave to
