  • 3a Pwm Solar Panel Charge Controller 12v 24v Battery Regulator - China

    price: contact company for price

    Pulse Width Modulation (PWM) is the most effective means to achieve constant voltage battery charging by adjusting the duty ratio of the switches ( MOSFET ). In PWM charge controller, the current from the solar panel tapers according to the battery’s condition and recharging needs. When a battery voltage reaches the regulation set point, the PWM algorithm slowly reduces the charging current to avoid heating and gassing of the battery, yet the charging continues to return the maximum amount of energy to the battery in the shortest time.
    1. High quality, reliable and economically priced charge controller
    2. PWM charge controller is a good low-cost solution for small systems
    3. Automatic 12/24v depends on battery voltage.
    4. Overcharge and over discharge protection for the battery.
    5. 3-stage charging algorithm, impulsive charge, bulk charge, floating charge Specification
    Nominal output(automatic identification): 12V/24V
    Operating current: 3A
    Short-term load current (60 seconds): 6A
    MAX Solar panel: 40W/80W
    Over-discharge protection: 10.8V/21.6V
    Overcharge protection: 14.4V/28.8V
    Float charge: 13.8V/27.6V
    PWM charging: YES

    This solar charge controller is perfect for 10W-25W solar panel system. Installation
    1. Connect the battery positive and negative to the controller.
    2. Positive and negative load wires to the controller, pay attention to cannot be reversed.
    3. Connect the solar panel to the controller correctly.
    4. Please follow the above sequence in strict order, otherwise, it may damage the controller. The disassembly order is the opposite of the wiring sequence.
