2. Safety Information
Please read and understand all safety instructions before installation and operation to prevent injury or damage to the controller and connected equipment.
- Battery Connection First: Always connect the battery to the controller first. Ensure the battery voltage is sufficient for the controller to recognize the correct system voltage.
- NEVER Connect Solar Panel Array Without Battery: Do not connect the solar panel array to the controller before connecting the battery.
- Disassembly Sequence: The disassembly sequence is contrary to the wiring order (disconnect solar panels first, then battery).
- Inverter/Charger Connection: DO NOT connect any Inverter, wind turbine, alternator, or external charger directly into the charge controller. Connect the Inverter directly to the battery.
- Solar Input Voltage: Ensure solar input voltage is at least 3V higher than the battery's voltage and that the total input power is within the specified range.
- Installation Location: DO NOT install the charging controller in direct sunlight to avoid power loss due to overheating.
- Ventilation: Remove all clutter around the controller to reduce interference and ensure enough space for heat dissipation (approximately 20cm clearance).
- Tight Connections: Ensure all connections going into and from the controller are tight.
- Polarity: DO NOT let the positive (+) and negative (-) terminals of the battery touch each other.

4. Setup and Installation
Proper installation is crucial for the performance and longevity of your solar charge controller. Follow these steps carefully:
- Mounting: Install the controller in a well-ventilated area, away from direct sunlight and heat sources. Ensure at least 20cm of clear space around the unit for proper airflow.
- Battery Connection: Connect the battery to the controller first. Ensure the battery voltage is sufficient for the controller to auto-detect the system voltage (12V/24V/36V/48V).
- Solar Panel Connection: After the battery is connected, connect the solar panel array to the controller. Ensure the maximum input voltage (150V PV) and power (1140W for 12V, 2260W for 24V, 3420W for 36V, 4540W for 48V) are not exceeded. The MPPT best working voltage range is DC18V-DC80V (12V), DC30V-DC100V (24V), DC65V-DC150V (48V).
- DC Load Connection: Connect your DC loads to the designated terminals.
- Tighten Connections: Double-check all wiring connections to ensure they are secure and tight to prevent loose connections and potential hazards.
5. Operating Instructions
The LCD display provides comprehensive information about the system's performance and allows for configuration adjustments.
LCD Display and Buttons
The LCD display shows real-time operating data, including daily power generation curves and current curves. Use the Menu, Down, Up, and Enter buttons to navigate through the display and adjust settings.
Battery Type Configuration
The controller supports charging for four types of batteries: Lead-acid (Sealed, AGM, Gel, Flooded) and User-defined (Lithium Battery). Ensure you select the correct battery type in the settings for optimal charging and battery health.
Load Control Modes
The controller offers multiple load control modes, allowing you to manage the power supply to your DC loads based on various parameters.
Wi-Fi Remote Monitoring (Optional)
The RS485 communication port enables Wi-Fi remote monitoring capabilities. This requires an additional purchase of a Wi-Fi module. Once connected, you can monitor and set parameters via a mobile application compatible with Android and iOS systems. The app allows for real-time wireless monitoring and offers a one-key restore to factory settings.

6. Maintenance
Regular maintenance ensures the optimal performance and lifespan of your solar charge controller.
- Connection Checks: Periodically inspect all wiring connections to ensure they remain tight and free from corrosion.
- Cleaning: Keep the controller clean and free from dust and debris. Use a dry cloth for cleaning.
- Ventilation: Ensure the cooling fan and ventilation openings are not obstructed.
7. Troubleshooting
This section addresses common issues you might encounter with your solar charge controller.
- Charging Indicator On/Off: If the charging indicator is intermittently on and off, and the charging current fluctuates, this is generally normal. It often occurs on cloudy days or in the evening when light is insufficient, indicating the controller is adjusting to available solar input.
- Controller Buzzing: If the controller produces a buzzing sound, it is typically due to the internal fan operating to dissipate heat. This is a normal function, especially under heavy load or high ambient temperatures. Allow the fan to operate as needed.
- Low Charging Current: If the charging current is almost zero when the controller is in floating charge mode, it may indicate that the solar input power is too low for the maximum input power capacity, or the battery is already fully charged.
