    Land Dream Series(LD in short) is an economical and traditional PWM solar controller.It can not only extend the service life of battery, but also provide necessary protection over the whole system. We own its outlook design patent.The double buttons and LCD screen show you the working parameters of the whole system, clear and understandable. This series is widely applied in solar home system, traffic signal, solar lighting system, etc.

    FEATURES:

    1.Automatic identify system voltage, totally compatible with 12V/24V

    2.LCD displaying and double button operation of man-machine interface.

    3.3 stage PWM charging mode: Bulk,Boost, Float.

    4.Load control mode:Sensor mode,Time mode,Discharging capacity limited mode.

    5.Operation log function:account charging and discharging ampere hour of the system the working days,times of HVD, times of LVD and times of over current protection.

    6.Accurate temperature compensation, it can automatically accommodate the charging voltage according to the environmental temperature, optimizing for long battery life.
