WS-AL2460 60A WELLSEE solar street light controller adopts PWM charging function, can active the battery, avoid the sulfide crystals and battery dehydration, so to extend battery life span. 

Functions: 

1. 12V/24V automatically detection

2. Intelligently senses the light outside, turn on automatically when getting dark and turn off when day break

3. Micro-processing controller pulse-width modulation (PWM) charging

4. Light intensity can be set to save energy consumption, thereby achieving the energy saving effect

5. It can prevent reverse charging (the battery charges the solar panel).

6. Lightning protection, short circuit protection (with self-recovery)

7. It can prevent anti-charging function (solar panels to charge batteries)

8. It can prevent reverse connection of the battery and solar panel.

9. It can set 20 time grade or 10 minutes section modes

10. It has a LET indicator of the working condition of charging and discharging:
