Disconnection Sequence: When disconnecting, always reverse the order: first solar panels, then load, then battery.
3.3 Connection Diagram
The diagram illustrates the typical flow: Solar Panel (DC) → MPPT Controller (DC) → Battery (DC). From the battery, power can go to a DC Load or to an Inverter (DC to AC) → AC Load. The Mobile APP can connect via Bluetooth to the MPPT Controller.
4. Operating Instructions
The Shiner2430 controller is designed for automatic operation once correctly installed. Here are key operational aspects:
4.1 Automatic Voltage Recognition
The controller automatically detects 12V or 24V battery systems upon initial connection.
4.2 MPPT Charging
The Maximum Power Point Tracking (MPPT) algorithm continuously tracks the maximum power point of the solar array to ensure the highest possible energy harvest, even under varying sunlight conditions.
4.3 Battery Type Selection
The controller supports multiple battery types, including Lead-acid and Li-ion, and allows for user-defined settings. Refer to the display and control buttons (SELECT/ENTER) for navigating menus and selecting the appropriate battery type for your system.
4.4 Load Operating Modes
The controller offers various load operating modes to manage the DC output to your loads. These typically include:
- Light Control: Load turns on/off based on ambient light levels.
- Time Control: Load operates for a set duration after dusk.
- Manual Control: Load can be manually switched on/off.
- Debugging Mode: For testing and setup.
- Normal Open: Load is always on when power is available.
Consult the on-screen display and control buttons to configure the desired load mode.
4.5 Mobile App Control
For enhanced monitoring and control, the controller supports Bluetooth connectivity with a dedicated mobile application. Download the official SRNE app to access real-time data, adjust settings, and manage your system remotely.
5. Maintenance
Regular maintenance ensures the longevity and optimal performance of your solar charge controller.
- Visual Inspection: Periodically check for any loose connections, damaged wiring, or signs of corrosion on the terminals.
- Cleaning: Keep the controller clean and free from dust and debris. Use a dry cloth to wipe the exterior. Do not use liquids or solvents.
- Ventilation: Ensure that the heat sink fins are not obstructed to allow for proper heat dissipation.
- Firmware Updates: Check the manufacturer's website or mobile app for any available firmware updates to ensure your controller has the latest features and bug fixes.
- Battery Health: Monitor your battery's health and ensure it is within its recommended operating parameters.
6. Troubleshooting
If you encounter issues with your Shiner2430 controller, consider the following common troubleshooting steps:
- No Display/Power:
- Check battery connections for proper polarity and secure contact.
- Ensure the battery voltage is within the controller's operating range (8V-32V).
- No Charging:
- Verify solar panel connections and polarity.
- Check if solar panels are receiving adequate sunlight.
- Ensure the PV input voltage is within the specified range (Max. Open Circuit Voltage 60V).
- Confirm the correct battery type is selected in the controller settings.
- Load Not Working:
- Check load connections and polarity.
- Verify the load operating mode settings.
- Ensure the battery has sufficient charge.
- Check for any overload or short-circuit protection activation.
- Error Codes: If the display shows an error code, consult the full product manual (if available) or contact SRNE support for specific interpretations and solutions.
