4. Setup and Installation
Proper installation is crucial for the safe and efficient operation of your solar charge controller.
Installation Steps:
- Mounting: Choose a well-ventilated, dry location away from direct sunlight and heat sources. Ensure the mounting surface is sturdy enough to support the controller's weight. Refer to the 'Specifications' section for mounting dimensions.
- Wiring Order: Follow the correct wiring sequence to prevent damage to the controller and other components.
- Connect the battery to the controller's battery terminals. Ensure correct polarity.
- Connect the solar panel(s) to the controller's PV terminals. Ensure correct polarity.
- Connect the DC load (if applicable) to the controller's load terminals. Ensure correct polarity.
- Wire Sizing: Use the recommended wire sizes as specified in the 'Specifications' section to minimize voltage drop and ensure safe operation.
- External Devices (Optional): If using external monitoring devices like the MT50 remote meter, or BLE/WiFi modules, connect them to the COM port as per their respective manuals.
5. Operation
Once installed, the controller will automatically begin operation. The LCD display provides real-time system information, and settings can be adjusted using the SELECT and ENTER buttons.
Initial Setup:
- The controller automatically identifies 12V/24V battery voltage.
- It is compatible with various battery types including Lithium, Sealed (SLD), Flooded (FLD), Gel, and AGM.
- For lithium batteries, the system voltage is not automatically identified and must be set manually.
Monitoring and Configuration:
- Use the SELECT and ENTER buttons to navigate through the display menus and adjust parameters.
- The controller supports remote monitoring and parameter setting via a mobile APP or PC software. This requires separately purchased BLE (Bluetooth Low Energy) or WiFi modules, or an MT50 remote meter.
Battery Voltage Parameters:
For lead-acid batteries, the controller uses default charging parameters. For lithium batteries or custom lead-acid settings, users can modify parameters like Boost Charging Voltage (BCV), Float Charging Voltage (FCV), Low Voltage Disconnect (LVD), and Low Voltage Reconnect (LVR) directly on the controller when the battery type is set to "USE".
6. Maintenance
Regular maintenance ensures optimal performance and extends the lifespan of your solar charge controller.
- Cleaning: Keep the controller clean and free from dust and debris. Use a dry cloth for cleaning.
- Connections: Periodically check all wiring connections to ensure they are tight and free from corrosion.
- Ventilation: Ensure that the ventilation openings are not blocked to allow for proper heat dissipation.
- Environmental Conditions: Operate the controller within its specified environmental parameters (Work Temperature Range, Storage Temperature Range, Relative Humidity).
7. Troubleshooting
The TracerAN series controller is designed with robust protection features. If you encounter issues, consider the following:
- No Display/Power: Check battery connections and voltage. Ensure the battery is connected first and has sufficient charge.
- No Charging: Verify solar panel connections and ensure there is sufficient sunlight. Check PV input voltage.
- Load Not Working: Check load connections and ensure the load is within the controller's rated current. Verify battery voltage is above the Low Voltage Disconnect (LVD) setting.
- Reduced Charging Power: The controller has a high temperature charging automatic power reduction function. If the internal temperature reaches 81℃, charging power will be reduced to protect the device. This is normal operation.
- Error Codes: Refer to the controller's display for any error codes and consult the full product manual (if available) for specific interpretations.
- Persistent Issues: If problems persist after checking the above, contact customer support.

9. User Tips
- Wiring Sequence is Key: Always connect the battery first, then the solar panels, and finally the load. Disconnect in the reverse order (load, then PV, then battery) to prevent damage.
- Lithium Battery Settings: If using lithium batteries, remember that the controller will NOT auto-identify the voltage. You must manually configure the battery type and voltage parameters (BCV, FCV, LVD, LVR) for optimal performance and battery health.
- Remote Monitoring: Consider purchasing an optional MT50 remote meter, BLE, or WiFi module for easier monitoring and parameter adjustment from a distance or via a smartphone app.
- Temperature Sensor: Some models come with a temperature sensor. Ensure it is properly installed and positioned to accurately measure battery temperature for correct temperature compensation.
- Ventilation: Even though the controller has overheating protection, ensuring good airflow around it will help maintain efficiency and prevent the power reduction feature from activating unnecessarily.
