The controller is for off-grid solar system and control the charging and discharging of the battery. Main function is protecting battery. The intelligent charging process has been optimized for long battery life and improved system performance.
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.
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 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.
