50A Pwm Solar Charge Controller 12/24V With LCD Screen for Solar PV System

50A pwm solar charge controller 12/24V with LCD screen for solar PV system

The features are listed below:

n           Automatic Identification System Voltage, 12V/24V auto recognition.

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

n           The load control mode can be selected, the timer function can be reset for street light at night.

n           Discharge capacity control

n           RS485 communication interface (optional)

n           Discharge Counter of Ampere Hour

n           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, correcting the charging and discharging voltage automatically, improving the battery lifetime.

n           Roundly reverse connected protection.

n           Solar Panels, Battery, Solar Charge Controller positive poles are all connected together, adopting negative MOSFET in series control circuit.

n           It is better to install the controller in the room. If installed the controller outside, please keep the environment dry, avoid direct sunlight.

n           The controller will be hot in process of working, please keep the environment ventilation, away from flammable.

n           The open circuit voltage of solar panel is too high, (especially 24V and 48Vsystem), please take care.

n           The battery has acidic electrolysis, please put on goggles during installation. If you accidentally exposed to the electrolysis, please rinse with water.

n           Please avoid reverse connection or short circuit connection under 48V system, or the product easy to destroy.

n           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.)

n           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.

n           Recommend system current density of cables less than 3A/mm² .

n           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.

n           The battery should be full charged each month. Or the battery will be destroyed.
