5. Installation and Wiring
5.1 Safety Precautions
- Ensure all connections are tight to avoid loose connections that may cause excessive heat.
- Always connect the battery first, then the solar panels, and finally the load. Disconnect in the reverse order.
- Install the controller in a well-ventilated area, away from direct sunlight and heat sources.
- Use appropriate wire gauges for all connections to prevent overheating and voltage drops.
5.2 Connection Steps
- Connect the Battery: Connect the battery cables to the battery terminals on the controller. Ensure correct polarity (positive to positive, negative to negative). The controller will detect the system voltage.
- Connect the Solar Panels: Connect the solar panel cables to the PV terminals on the controller. Ensure correct polarity. The controller will begin charging the battery.
- Connect the DC Load (Optional): If using a DC load directly from the controller, connect the load cables to the load terminals. Ensure correct polarity.

6. Operation
The Tracer AN controller features an LCD display and two buttons (SELECT and ENTER) for monitoring system status and configuring parameters.
6.1 Display Navigation
- SELECT Button: Press to cycle through different display screens, showing real-time data such as PV voltage, battery voltage, charging current, and load status.
- ENTER Button: Press and hold to enter parameter setting mode. Once in setting mode, use the SELECT button to navigate between parameters and the ENTER button to confirm changes.
6.2 Battery Type Setting
For lithium batteries, the system voltage and battery type must be manually configured. Refer to the detailed instructions in the full user manual for specific steps on setting battery parameters.
7. Maintenance
Regular maintenance ensures optimal performance and longevity of your solar charge controller.
- Check Connections: Periodically inspect all wiring connections for tightness and corrosion. Loose connections can lead to voltage drops and overheating.
- Clean the Controller: Keep the controller clean and free from dust and debris. Ensure the heat sink fins are not obstructed to allow for proper cooling.
- Inspect Wiring: Check all cables for signs of wear, damage, or fraying. Replace any damaged cables immediately.
- Monitor Performance: Regularly check the display for normal operation and any error codes. Compare actual system performance with expected values.
8. Troubleshooting
This section covers common issues you might encounter with your Tracer AN controller.
| Problem | Possible Cause | Solution |
|---|---|---|
| No display/Controller not powering on | Battery not connected or low voltage; reverse polarity. | Check battery connections and voltage. Ensure correct polarity. Charge battery if voltage is too low. |
| No charging from PV | PV panels not connected; reverse polarity; insufficient sunlight; PV voltage too low/high. | Check PV connections and polarity. Ensure adequate sunlight. Verify PV open circuit voltage is within controller limits. |
| Battery not fully charged | Incorrect battery type setting; insufficient PV power; high self-consumption. | Verify battery type setting. Increase PV array size if needed. Reduce load if possible. |
| Load not working | Load disconnected; overload; short circuit; low battery voltage disconnect. | Check load connections. Reduce load. Check for short circuits. Charge battery. |
For detailed error codes and advanced troubleshooting, please consult the comprehensive user manual or contact technical support.
9. User Tips
- Always ensure your battery bank is adequately sized for your solar array and load to prevent over-discharge or undercharging.
- When connecting lithium batteries, remember to manually set the battery type and voltage parameters in the controller's settings.
- Consider using an external temperature sensor (if available for your model) for more accurate battery temperature compensation, especially in environments with significant temperature fluctuations.
- For optimal performance, keep the controller in a cool, dry place with good airflow to prevent overheating.
