WS-L2430 12/24V 20A, 25A, 30A Solar Street lamp controller is controlled by micro-CPU and intelligently senses outside light. It will automatically turn on lights at dark. This controller also intelligently monitors battery charging and discharging. It will protect batteries by turning off lights automatically when the battery boltage is low. The controllers will floatcharge the batteries by pulse-width-modulation (PWM) automatically as the batteries approach full charge. It will cut off charging current to protest batteries from discharging through the solar panel at dark. The controller also has a protection circuit to prevent accidental damage.
Functions:
1. It can prevent the battery from over-charging and over-discharging.
2. It can prevent reverse 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. It will shut down the lighting system according to the time setting or shut down the lighting system automatically when it is dawn.
Indicator Light:
The controller has a three color battery power indicator LED light, and a green load indicator light. They indicator of the working condition of charging and discharging:
1. The red indicator LED light (CHARGE) will light when the batteries are being charged through the solar panel.
2. The green LOAD LED will light when the load is turned on.
3. The LOAD indicator also helps with testing and setup.
4. The three color battery power indicator light will be red if the battery voltage is low, orange during normal working range and green for a fully charged battery
