2.2 Setup and Connection

Important: Connect the components in the specified order to prevent damage to the controller. Disassembly should be done in the reverse order.

1. Connect Battery: First, connect the battery to the charge controller. Ensure the battery has sufficient voltage for the controller to recognize the correct battery type (12V or 24V).
2. Add Solar Panels: Connect the solar panels to the charge controller.
3. Connect DC Loads (Optional): If using DC loads directly from the controller, connect them next.
4. Connect Inverter (Optional): If using an inverter, connect it to the battery bank.

3.3 LCD Display and Settings

The LCD display provides real-time status and data. Use the buttons below the display to navigate and configure settings.

Figure 8: MPPT Controller LCD Display and Setting Interface. Cycle through Battery Voltage, Solar Panel Charge Current, Load Discharge Current, High Voltage Disconnection (HVD), Accumulated Discharging Power (Ah), Accumulated Charging Power (Ah), Low Voltage Reconnection (LVR), Low Voltage Disconnection (LVD), and Load Working Mode.

Operation Instructions:

• Short press the menu button to cycle through the interface and parameters.
• Long press the menu button for 3 seconds to enter the settings manually. The number will flash. Adjust values using the up/down keys. After completion, the system automatically saves settings and exits setup mode.

Function Declarations:

• Discharge recovery voltage: Refers to the battery discharge protection. The battery voltage to restore voltage, open the output.
• Discharge cut-off voltage: Refers to the battery discharge to the voltage when the load is off, to protect the battery, to prevent the battery over discharge damage.
• Load operation mode:
  • [24H] Load output 24 Hours: (except for battery under voltage)
  • [1-15H] Load on after sunset and closed after setting hours:
  • [0H] Dusk to dawn:

Note:

• The light control function is controlled by the solar panel. The use of light control function requires access to the solar panel, otherwise the light has no effect.
• The load symbol (light bulb icon) indicates that the load output has been turned on, and there is no connection to the load.
• For [1-15H] or [0H] modes, the optical delay model is battery not under pressure condition. The battery symbol does not blink. Single short press the turn key can open/close load output.

4. Safety Precautions

• Ensure all connections are tight and correct to avoid loose connections that can cause excessive heat.
• Always connect the battery first, then the solar panels. Disconnect in reverse order.
• Do not attempt to repair or modify the controller yourself. Contact qualified personnel for service.
• Install the controller in a well-ventilated area, away from direct sunlight, high temperatures, and moisture.
• Use appropriate circuit breakers or fuses for all connections to protect against overcurrent.

5. Maintenance

• Regularly check all wiring for signs of wear, damage, or loose connections.
• Keep the controller clean and free from dust and debris. Use a dry cloth for cleaning.
• Ensure proper ventilation around the controller to prevent overheating.
• Monitor the LCD display periodically to ensure normal operation and correct parameter settings.

6. Troubleshooting

If you encounter issues, refer to the following common problems and solutions:

• Controller not turning on: Check battery connections and ensure the battery has sufficient voltage.
• No charging current: Verify solar panel connections, ensure panels are receiving sunlight, and check for any shading.
• Load not working: Check load connections, ensure the load is within the controller's capacity, and verify load output settings on the LCD.
• Battery not fully charging: Check solar panel output, battery health, and charging parameters on the controller.
• Error codes on display: Consult the specific controller's detailed manual (if available) or contact customer support with the error code.
