4. Setup and Installation

4.1 Mounting the Controller

Securely mount the controller on a wall using four screws. Ensure adequate clearance around the controller for proper airflow and heat dissipation. A minimum of 75mm (approximately 3 inches) clearance is recommended on the top, bottom, left, and right sides.

Figure 6: Recommended mounting clearances (75mm on all sides) for optimal air circulation and heat dissipation.

4.2 Wiring Connections

Follow the wiring diagrams carefully. Loosen the terminal screws before inserting wires, then tighten them securely. Recommended wire size: 9AWG.

• Connect the battery wires first (positive and negative).
• Connect the solar input wires (positive and negative).
• Connect the DC load wires (positive and negative).

4.3 Parallel Operation Setup

For parallel operation, multiple controllers can be connected to the same battery bank. Each controller should have individual connections to separate photovoltaic arrays. Communication lines must be configured between controllers for proper synchronization.

5. Operating Instructions

5.1 Display Interface

After startup, the controller's LCD display shows various parameters. Use the "Up" and "Down" buttons to navigate through the main loop interfaces:

• Interface 1: Solar input voltage (PV) and load power consumption (LOAD).
• Interface 2: Battery voltage (BATT) and charging current (CHARGE).
• Interface 3: Operating mode and device temperature (TEMP).
• Interface 4: Fault codes (FAULT) and parallel operation code.

5.2 Parameter Settings

Press the "PRG/ESC" button to enter the settings interface loop. Use "Up" and "Down" to navigate and "ENTER" to confirm changes.

• d00 (Load Operating Mode):
  • 24H: Load is continuously on.
  • 00H: Light control mode (load output determined by sufficient solar energy).
  • 1H to 23H: Timed light-on and constant-off mode (load output activated upon detecting photovoltaic input and remains on for the set duration).
• d01 (Charging Voltage): Configures the voltage the controller maintains after the battery completes the boost charging stage.
• d02 (Boost Charging Voltage): Sets the charging voltage during the boost charging stage.
• d03 (Low Voltage Protection): Sets the low voltage protection voltage of the battery.
• d04 (Battery Voltage Calibration): Used to calibrate the battery voltage value displayed by the controller. If the displayed value differs from a multimeter reading at the battery port, use this program to calibrate.
• d05 (Parallel Communication Code): Configures the communication address of the controller in parallel operation. The controller with the lowest communication code acts as the master. If the main controller (code 1) fails, functions will cascade to the next valid operating controller.
• d06 (Battery Type Setting): Sets the battery type with options including sealed lead-acid batteries, gel-sealed lead-acid batteries, flooded lead-acid batteries, 4-string lithium iron phosphate batteries, 8-string lithium iron phosphate batteries, 15-string lithium iron phosphate batteries, 16-string lithium iron phosphate batteries, and custom options ("USE"). Choosing "USE" allows manual settings for "d01", "d02", and "d03".
• d07 (System Voltage Configuration): Configures the system voltage.

After completing the settings, press the "ESC" key to exit and return to the main page.

6. Maintenance

• Regularly inspect all wiring connections for tightness and corrosion.
• Keep the controller clean and free from dust and debris to ensure proper heat dissipation.
• Check the fan for obstructions and ensure it operates correctly when activated.
• Monitor the display for any fault codes and address them promptly.

7. Troubleshooting

If the controller is not functioning as expected, consider the following:

• No Display/Power: Check battery connections and ensure the circuit breaker is on.
• No Charging: Verify solar panel connections and ensure sufficient sunlight. Check for any fault codes on the display.
• Overheating: Ensure adequate ventilation and clearance around the controller. Clean any dust or debris from the cooling fins.
• Incorrect Readings: Calibrate battery voltage using the d04 setting if necessary.
• For persistent issues, refer to the detailed troubleshooting section in the full product manual or contact customer support.
