4. Setup

4.1 Mounting the Controller

• Choose a well-ventilated, dry, and dust-free location.
• Mount the controller vertically on a non-flammable surface, ensuring adequate clearance around the heat sink for natural cooling.
• Avoid direct sunlight, high temperatures, and moisture.

4.2 Wiring Instructions

Important: Always connect the battery first, then the solar panel, and finally the load. Disconnect in the reverse order: load, then solar panel, then battery.

Figure 4: Controller Terminals (PV+, PV-, BAT+, BAT-, LOAD+, LOAD+)

1. Connect the Battery: Connect the positive (+) and negative (-) terminals of your battery bank to the corresponding BAT+ and BAT- terminals on the controller. Ensure correct polarity. The controller will power on.
2. Connect the Solar Panel: Connect the positive (+) and negative (-) terminals of your solar panel array to the corresponding PV+ and PV- terminals on the controller. Ensure correct polarity.
3. Connect the DC Load: Connect your DC loads to the LOAD+ and LOAD+ terminals. Note that both LOAD+ terminals are typically common positive outputs, and the LOAD- terminal is the common negative output. Ensure correct polarity.
4. Optional Connections:
   • Temperature Sensor (Temp): Connect the external temperature sensor (if included) to the 'Temp' port for accurate battery temperature compensation.
   • Communication (TTL/RS485/CAN): Use the TTL, RS485 (RJ45), or CAN (RJ45) ports for communication with external devices or monitoring systems.
   • Bluetooth Module: If using the optional BT-2 Bluetooth module, connect it to the designated port for mobile APP connectivity.

4.3 Connection Diagram Overview

The general connection flow is as follows:

• Solar Panel (DC) → MPPT Controller (DC) → Battery (DC)
• MPPT Controller (DC) → DC Load
• Battery (DC) → Inverter (AC) → AC Load (if using an inverter)
• MPPT Controller (Bluetooth) → Mobile APP (for monitoring)

5. Operating Instructions

5.1 Display and Button Functions

The controller features a display and two buttons, typically labeled 'SELECT' and 'ENTER', for navigating menus and adjusting settings.

• SELECT Button: Used to cycle through display screens or menu options.
• ENTER Button: Used to confirm a selection or enter a menu for parameter adjustment.

5.2 Load Operating Modes

The Shiner2440 supports various load operating modes to control the DC output:

• Manual Control (Default): The load output is controlled manually via the controller's buttons or mobile app.
• Light Control: The load output is automatically turned on or off based on ambient light levels (e.g., dusk to dawn).
• Time Control: The load output is turned on or off according to a pre-set schedule.
• Debugging Mode: A special mode for testing and troubleshooting.
• Normal Open: The load output is continuously on, regardless of light or time settings.

Refer to the on-screen menu or mobile application for detailed configuration of these modes.

5.3 Mobile APP Connectivity

If you have the optional BT-2 Bluetooth module, you can connect your Shiner2440 to a mobile application for advanced monitoring and control. Download the official SRNE app from your device's app store. The app allows you to:

• Monitor real-time system data (PV voltage, battery voltage, charging current, load current).
• View historical data and energy statistics.
• Adjust charging parameters and load control settings.
• Update firmware (if available).

6. Maintenance

Regular maintenance ensures the longevity and optimal performance of your solar charge controller:

• Cleanliness: Keep the controller clean and free from dust and debris. Use a dry cloth to wipe the exterior.
• Connections: Periodically check all wiring connections for tightness and corrosion. Loose connections can cause overheating and damage.
• Ventilation: Ensure that the ventilation openings and heat sink are not obstructed to allow for proper heat dissipation.
• Battery Inspection: Regularly inspect your battery bank for any signs of damage, corrosion, or electrolyte leakage.
• Firmware Updates: Check for available firmware updates via the mobile app or manufacturer's website to ensure you have the latest features and bug fixes.

7. Troubleshooting

If you encounter issues with your Shiner2440 controller, consider the following common troubleshooting steps:

• Controller Not Powering On: Check battery connections and ensure correct polarity. Verify battery voltage is within the controller's operating range (8V-32V).
• No Charging: Ensure solar panels are connected correctly and receiving sufficient sunlight. Check PV voltage and current. Verify that the PV open circuit voltage does not exceed 60V.
• Load Not Working: Check load connections and ensure correct polarity. Verify that the load operating mode is set correctly (e.g., not in 'Off' or 'Light Control' during daylight). Check for any overload or short-circuit protection activations.
• Abnormal Readings: Ensure all sensors (e.g., temperature sensor) are properly connected.
• Error Codes: If the display shows an error code, consult the full product manual (if available) or contact customer support with the specific code.

Always disconnect power sources in the reverse order of connection (load, then PV, then battery) before performing any inspection or maintenance.

8. User Tips

• For optimal performance, ensure your solar panel array's voltage is consistently above the battery voltage plus 2V, but below 45V for MPPT tracking.
• Utilize the mobile application for convenient monitoring and to fine-tune settings without needing direct access to the controller.
• When selecting battery type, 'User Defined' allows for custom charging parameters, which is crucial for specific battery chemistries like Li-Ion. Ensure these settings match your battery manufacturer's recommendations.

9. Warranty and Support
