Introduction:

Our SLC series solar light controller that adopts the most advance digital technique and operates fully automatically. The pulse width modulation (PWM) batteries charging can greatly increase the lifetime of battery.

Features:
It has various unique functions and quite easy to use, such as:
● 12/24V automatic recognition
● High efficient series PWM charging, increase the battery lifetime and improve the solar system performance.
● Use MOSFET as electronic switch, without any mechanical switch.
●Widely used, automatically recognize day / night.
●Digital LED menu, only one key solve all setting simply.
● Intelligent timer function with 1-15 hours option.
●Unique dual timer function, enhance the flexibility of street light system.
●Gel, Sealed and Flooded battery type option.
●Adopt temperature compensation, correct the charging and discharging parameters automatically and improve the battery lifetime.
●Electronic protection: overheating, over charging, over discharging, overload, and short circuit.
●Reverse protection: any combination of solar module and battery.
