Quick Overview

5/10/15/20/30A PWM Solar Panel Battery Regulator Charge Controller 12V/24V

Product Details


  • Always keep the battery on fill voltage condition.
  • Prevent the battery from over-charging and over-discharging.
  • Prevent the battery from reverse charging to solar panels during nights.
  • Reverse Polarity Protection for Battery and Solar Panels.
  • Fully automatic operation, When the battery voltage is low, the controller will automatically cut off the load from the system. If the voltage of battery is back to normal and the load will restart working.
  • Thunder protection, Electronic protection.
  • According to the battery voltage grade, the controller can automatically set charge-ff voltage, the load-off voltage, the load- restore voltage. (The parameter is default under 25℃ condition, locked by the CPU procedure, cannot adjust.)
  • The controller will automatically compensate the temperature of the charging voltae according to the changes of ambient temperature.
  • 5A /10A /15A /20A /30A for you to choose
  • PWM charge mode(SOC)
  • Micro-controller digital accuracy
  • Suitable for all 12/24V DC lamps
  • Big terminals, big distance between terminals

    Full consideration to the safety of persons and property has been given when designing, the products. However the incorrect connection may cause the system breakdown or even safety accident. For your safety and benefits, the following rules must be complied during the operation.

  • Installation of this product shall be tinder the guidance of the professionals in this field.
  • Prevent this controller from water, humidity and insects, to avoid short-circuit.
  • Keep children and incapable persons away from the controller.
  • Keep the controller away from electrical heater, heating machine and other high temperature electrical appliances; avoid the controller suffering from insulation directly.
  • Please check the rated voltage of solar panel, battery, and loads before connection. 12V rated voltage is 12V, 24V rated voltage is 24V.
  • Make sure connections between positive and negative poles of Solar panels, Battery and Loads are correct.
  • The diameter of connecting cable must be matched with the requirements of the current. Do not use thinnerdiameter cable, the thinner diameter. The larger resistance, this will cause highr temperature and output power decreasing.
  • The total rated current of solar panel and loads must be smaller than the rated current of the controller.
  • Components of system must be correctly and firmly connected. Prevent the terminals from oxidation and moldy,to avoid connection trouble.
  • Specifications:

  • Before connecting to the solar panel, please connect the controller to the battery; do not use solar panel supply power to the loads directly.
  • Do not use lamplight to charge the solar panel (lamplight is too weak to charge)
  • DC power source to replace the solar panel will cause troubles to controller.
  • Choose the suitable wire which diameter should not be too small, please refer to the parametr.
  • Parameters:

    Solar Panel Battery Regulator Charge Controller


    • Phenomenon 1: Green LED off, battery indicator LED is red.
    • Reason: Low voltage of battery
    • Solution:
        A: Cut off the power, disconnect the load; reconnect the load after the charge become normal.
        B: Battery charge problem: Increase the solar panel power or change the battery.
    • Phenomenon 2: Battery indicator LED is orange and Load indicator LED is green, the loads cannot work.
    • Reason: Over load or short-circuit causes the controller inner fuse cut off.
    • Solution: 10-20 minutes after eliminated the malfunction, the fuse will automatically back to working.

    Package Included:

    • 1 x PWM Solar Charge Controller
    • 1 x User Manual
