WS-L4860 50A Wellsee solar street light controller adopts micro controller which can intelligently perceive the light
intensity, thus it turns on automatically when it is dark and turns off automatically to the fixed time or dawn. The operation
condition of the controller is easy checking with its accurate LED display, and adapts to cold, heat, humidity and other
harsh environment. The environmental protection grade is IP22.
Functions
1.It can prevent the battery from over charging and over discharging.
2.It can prevent reversed charging (the battery charges the solar panel).
3.It can prevent reverse connection of the battery and solar panel.
4.It will start up the lighting system in the evening automatically according to the intensity of the light.
5.20 regular time modes and 10 sectional models can be set.
6.It has a LED indicator of the working condition of charging and discharging.
² One piece of Charge Indicator LED (mark: Charge). When it is bright, the battery is charged strongly; flickeringly
means floating charge, no light means stop charging.
² One piece of Load Indicator LED (mark:load). When it is bright, there is output and load can work; if LED goes out,
means there isnt output and the load cannot work.
² Battery indicator: red under =voltage Green =full Yellow =normal
