This 12V/24V 30A is an Advanced PWM solar charge controller for a solar power system to charge the lead-acid batteries and power up the load. It features a Digital LCD and input Button keys for the interface, and advanced features like built-in short-circuit protection, open-circuit protection, reverse voltage protection, overload protection, etc., making it ideal for off-grid power systems.

The solar charge controller is a part of the PV solar power system. It regulates the flow of electricity from the photovoltaic (PV) solar panels to the compatible battery bank or load, preventing overcharging and maintaining optimal battery performance. Without a charge controller, your batteries may be damaged by excessive charging, reducing their lifespan and potentially leading to safety hazards. These charge controllers also stop/prevent reverse current flow from batteries to the solar panels during low-light conditions, further protecting your system.

This 12V/24V 30A Advanced PWM solar charge controller is an advanced, multifunctional charge controller designed with an Industrial-grade master chip, 16 AD sampling accuracy for managing the power from solar panels to batteries in 12V/24V systems. This solar regulator utilizes a PWM Architecture  to identify the panel's Maximum Power Point  for high charging efficiency, non-stop detection during charging, and bidirectional focus tracking with 30A maximum charge current, making it ideal for off-grid systems, solar-powered lights, or electronic devices. The Controller features an LCD, which provides real-time monitoring of the solar panel input, battery voltage, and charging status, offering full control over the energy flow in your solar system. The controller also includes a R5.0 female DC plug for solar charging and load output for a convenient connection, dual USB port, allowing users to charge mobile devices and small electronics directly from the solar power system, making it a practical choice for solar-powered street lights, outdoor lighting, or remote applications. The intelligent regulation system ensures the protection of the connected batteries by automatically adjusting the charge cycles, preventing overcharging, over-discharging, and short circuits, thereby maximising the lifespan and performance of your solar batteries.

Note:

  • This product is labelled "MPPT" to refer to its Digital Tracking Software, which monitors the power curve of the solar panel. However, this unit does not contain a DC-to-DC transformer (Buck Converter).
  • The Input Current and Output Current will remain approximately the same.
  • It will not "boost" amperage by dropping high panel voltage.
  • If you are using a 24V panel to charge a 12V battery, you will experience the power loss typical of PWM charging.

Features:

  • Advanced PWM Solar Charge Controller
  • LCD for easy battery and system monitoring.
  • Dual MOSFET reverse current protection to prevent energy loss.
  • Low heat production for stable, long-lasting performance.
  • R5.0 female DC plug for solar charging and load output for a convenient connection

Frequently Asked Questions (Technical SEO)

  • Is this a true Buck-Converter MPPT or a PWM controller? This unit uses PWM (Pulse Width Modulation) architecture. While the software logic includes tracking features, it does not have the internal transformer hardware to convert excess voltage into additional amperage.
  • Why does the casing have "MPPT" printed on it? The manufacturer labels this as MPPT to signify the "Maximum Power Point Tracking" software algorithm used to optimise the charging curve, though the hardware operates on a PWM platform.
  • Can I use this with a 24V solar panel to charge a 12V battery? Yes, it will work, but it will be inefficient. Because it is PWM-based, the output current to your battery will be the same as the input current from the panel, wasting the extra voltage.
  • What is the maximum solar panel wattage I can connect? For a 12V system, the max is 390W. For a 24V system, the max is 780W.
  • What is the maximum input voltage (VOC) this controller can handle? The maximum open-circuit voltage (VOC) is 50V. Exceeding this will damage the controller.
  • Will this controller "boost" my current like an expensive MPPT? No. In this controller, the Input Amps will roughly equal the Output Amps. It does not "trade" voltage for extra current.
  • Which battery types are supported? It supports Lead-Acid (Open, AGM, Gel). If using Lithium, ensure the charging voltages (B01-B03 settings) match your battery manufacturer's specs.
  • Can I use this to charge a 48V battery bank? No. This controller is designed strictly for 12V or 24V systems and auto-detects the battery voltage upon connection.
  • Does it support Lithium Iron Phosphate (LiFePO4) batteries? While it has adjustable parameters, it does not have a dedicated LiFePO4 preset. Manual voltage adjustment is required.
  • What is the correct sequence for connection? Important: Always connect the Battery first, then the Solar Panel. When disconnecting, remove the Solar Panel first, then the Battery.
  • Why is the LCD screen blank? The controller is powered by the battery, not the solar panel. If the screen is blank, check your battery connections or ensure the battery has at least 8V-9V of charge.
  • What are the dual USB ports for? The USB ports provide a combined 5V/2A output, ideal for charging mobile phones or small electronic gadgets directly from the battery.
  • What does the "Load" terminal do? The Load terminals allow you to connect DC appliances (like LED lights) directly to the controller. You can program them to turn on/off based on the time of day or battery voltage.
  • Does it have overcharge protection? Yes. The controller automatically stops charging when the battery reaches the "Full" voltage setting to prevent gassing and plate damage.
  • Is the controller waterproof? No. This is an IP30-rated device meant for indoor use or weather-protected enclosures. Keep it away from moisture and direct sunlight.
  • Why is my battery not charging even though the sun is out? Check if the "Solar" icon is visible on the LCD. If not, check your panel polarity and VOC. Also, ensure the battery isn't already at the "Float" voltage.
  • Why does the controller get warm during use? It is normal for the backplate to get warm when handling high currents (near 30A). Ensure it is mounted vertically on a non-flammable surface with room for airflow.
  • Can I connect an Inverter to the "Load" terminals of the controller? No. Never connect an inverter to the controller's load terminals. Inverters should be connected directly to the battery due to high surge currents.
  • How do I reset the controller to factory settings? Navigate to the main interface, press and hold the "Menu" button for several seconds until the parameters begin to flash or reset.
