ldsolar 2021 Best Land Dream Series PWM Solar Charge Controller
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.
Land Dream Series PWM Solar Controller
Land Dream Series PWM Solar Controller.Thank you for selecting our product. Please read this manual carefully before you use this product. The controller is for off-grid solar system. Main function is protecting battery to prevent battery from over-charging and over-discharging. The intelligent charging process can efficiently extend service life of battery as well as improve system performance.n Automatic Identify System Voltage, totally compatible with 12V/24V.n Humanized LCD displaying and double button operation of man-machine interface.n Completed technical data for setup and modify.n High efficiency intelligent PWM 3stage charging moden The load control mode can be selected, the timer function can be reset for street light at night.n Discharge capacity controln RS485 communication interface (optional)n Charge and Discharge Counter of Ampere Hourn Working Storage Function: record the total run time of system, record timers of error during running time, record times of full charged battery.n Reliable over voltage protection, short circuit protection, over load protection, overcharge protection, over-discharge protection.n Accurate temperature compensation, it can automatically accomodate the charging voltage according to the environmental temperature, optimizing the battery lifetime.n Roundly reverse connected protection.n Solar Panels, Battery, Solar Charge Controller positive poles are all connected together, adopting MOS FET in series to control circuit.n We suggest that controller should be installed indoors. Outdoor installation should keep environment dry, avoid direct sunlight n The controller will generate heat in the process of working, please keep the environment ventilation, and stay away from flammable.n The open circuit voltage of solar panel is too high, (especially 24V and 48Vsystem), please take care.n Battery contains acidic electrolyte. Please wear goggles in the process of installation.Please wash with water immediately when you exposed to acidic electrolyte carelessly . n Battery contains huge power, and prohibit short circuiting positive and negative poles of battery. We suggest that you should install the fuse between battery and controller(slow motion type, the action current should be 1.5 times more than the system current of controller.n Controller can adjust voltage of charging by detecting environment temperature, so that the controller should be closed to battery as near as possiblen Suggest that the current density of the wire connected to system should under 3A/mm2n Try to choose stranded copper wire, which can ensure better connect to terminal. Insecure connect will lead to connector generate heat and melt terminal or shell, even cause a fire.n The battery should be full charged each month constantly(at least once per month), or battery will be damaged.
