PDF File: LD2420C controller

Major Functions

The features are listed below:
Automatic Identification System Voltage, 12V 24V auto recognition
Humanized LCD displaying and double button operation of man-machine interface.
Completed technical data for setup and modify.
High efficiency intelligent PWM 3stage charging
The load control mode can be selected, the timer function can be reset for street light at night.
Reliable over voltage protection、short circuit protection、over load protection、 overcharge protection、 over-discharge protection.
Accurate temperature compensation, correcting the charging and discharging voltage automatically, improving the battery lifetime.
Roundly reverse connected protection.
Solar Panels, Battery, Solar Charge Controller positive poles are all connected together, adopting negative MOSFET in series control circuit.

Important Safety Information

It is better to install the controller in the room. If installed the controller outside, please keep the environment dry, avoid direct sunlight.
The controller will be hot in process of working, please keep the environment ventilation, away from flammable.
The open circuit voltage of solar panel is too high, (especially 24V system), please take care.
The battery has acidic electrolysis, please put on goggles during installation. If you accidentally exposed to the electrolysis, please rinse with water.
The battery has huge power, prohibit any conductor short circuit the positive and negative pole of battery. Suggest to adding a fuse between battery and controller. (Slow motion type, the action current of the fuse should be 1.5 times rated current of controller.)

The suggestion of using

The controller could detect the temperature of environment to adjust the voltage of charging, so that the controller should be closed to battery as near as possible.
Recommend system current density of cables less than 3A/mm2 .
Try to use multi strand copper wire in order to connecting with the terminal firmly. Loose power connection and/or corroded wires may result in resistive connections that melt wire insulation, burn surrounding materials or even cause fire.
The battery should be full charged each month. Or the battery will be destroyed.
