For safe and optimum performance, your PWM solar charge controller must be used properly. Carefully read and follow all instructions and guidelines in this manual and give special attention to the CAUTION and WARNING statements. Misuse may damage the unit or cause harm or serious injury.

PWM Solar Charge Controller features

PWM solar charge controllers are designed to regulate the flow of electricity from a solar panel to a battery. PWM stands for “pulse width modulation,” and refers to the way in which the controller regulates the flow of electricity.

PWM controllers can also be used with other types of batteries, such as lead-acid batteries. However, PWM controllers are not suitable for all applications, and should only be used if there is a need to regulate the flow of electricity. This requires an understanding of the PWM solar charge controller settings. All batteries require a different type of charging process.

  • 12V/ 24 V system voltages are automatically recognized.
  • Charging program options for sealed, GEL, and flooded lead-acid batteries and lithium batteries are available.
  • An upgraded 3-stage PWM charging algorithm is adopted. The application of an equalizing charge to the battery periodically or when over-discharged can effectively prevent the battery from non-equalization and sulfuration, thus extending the battery’s service life with the exception of GEL and lithium batteries.
  • With temperature compensation employed, charging parameters can be automatically adjusted with the exception of lithium batteries.
  • A wide range of load working modes facilitate the product’s application to different types of street lights and monitoring devices.
  • The product provides overcharge, over-discharge, and overload protection, as well as short-circuit and reverse-connection protection.
  • A range of parameter settings and power-down saving functions are available, thus requiring no repeated setting.
  • The product provides a dot matrix graphic LCD screen and a human-machine interface with 2 keys.
  • The user-friendly design of the browser and dynamic interfaces ensures convenient and intuitive operations.
  • An optional communication function provides an RJ12 data port output of TTL232 level or blue tooth signals, with the data adopting the standard Modbus protocol, which can be used together with our upper computer monitoring software or mobile phone APP.
  • TVS lighting protection is adopted.

Frequently Asked Questions

  1. How do you use a PWM solar charge controller?

    Here are the steps to use a PWM solar charge controller:
    Connect the solar panel(s) to the charge controller’s solar input terminals.
    Connect the battery to the charge controller’s battery terminals. Make sure to connect the positive (+) and negative (-) terminals correctly.
    Turn on the charge controller by pressing the power button or switch.
    Set the charging parameters according to the battery type, capacity, and voltage. This can usually be done through the charge controller’s display or buttons.
    Monitor the charge controller’s status and make adjustments as needed. Some charge controllers have built-in features such as overcharge protection, low voltage disconnect, and temperature compensation.
    Disconnect the solar panel(s) and battery before making any changes to the wiring or components.

  2. How do you program a solar charge controller?

    To program a solar charge controller, you will need to follow the specific instructions for your particular model, as different models may have different programming methods. However, here are some general steps that can be followed:
    Connect the solar panel(s) and battery to the charge controller.
    Turn on the charge controller and access the programming mode. This can usually be done by pressing and holding a button or combination of buttons on the controller.
    Use the controller’s display and buttons to navigate through the programming options. These options may include battery type, charging parameters, load output settings, and other features.
    Select the appropriate settings for your system, based on the battery type, capacity, and voltage, as well as the solar panel specifications.
    Save the settings and exit programming mode.
    Monitor the charge controller’s status and make adjustments as needed.

  3. How do I know if my charge controller is working?

    There are several ways to determine if your solar charge controller is working properly:
    Check the controller’s LED indicators: Most solar charge controllers have LED indicators that show the charging status. If the green LED is on, it means the battery is fully charged. If the yellow LED is on, it means the battery is charging. If the red LED is on, it means there is a problem with the charging system.
    Monitor the battery voltage: You can use a multimeter or voltmeter to measure the battery voltage. If the voltage is increasing, it means the battery is being charged. If the voltage is decreasing, it means the battery is discharging.
    Check the solar panel output: You can use a multimeter or voltmeter to measure the voltage and current output of the solar panel. If the voltage and current are within the expected range, it means the solar panel is working properly.
    Monitor the load output: If your charge controller has a load output, you can connect a device to it and check if it’s receiving power. If the device is working, it means the load output is working properly.
    Check the charge controller’s manual: The manufacturer’s manual will have troubleshooting tips and information on what to look for if the charge controller is not working properly.

  4. How do I reset my solar PWM controller?

    To reset a solar PWM (Pulse Width Modulation) controller, you can follow these steps:
    Disconnect the solar panel(s) and battery from the charge controller.
    Locate the reset button or switch on the charge controller. It may be labeled as “RESET” or “RST”.
    Press and hold the reset button or switch for several seconds, or until the controller’s LED indicators turn off and then back on.
    Release the reset button or switch.
    Reconnect the solar panel(s) and battery to the charge controller.
    Turn on the charge controller and check that it’s working properly.
