4. Setup and Installation
4.1 Mounting the Controller
- Choose a dry, well-ventilated location, protected from direct sunlight, high temperatures, and moisture.
- Ensure sufficient clearance around the controller for heat dissipation.
- Mount the controller vertically on a wall or suitable surface using appropriate fasteners.
4.2 Wiring Connections
Important: Always connect in the following order: Battery → Solar Panel → Load. Disconnect in the reverse order.
- Connect the Battery: Connect the positive and negative terminals of the battery to the corresponding battery terminals on the controller. Ensure correct polarity. The controller will automatically detect the system voltage (12V or 24V).
- Connect the Solar Panel: Connect the positive and negative terminals of the solar panel array to the corresponding PV terminals on the controller. Ensure correct polarity.
- Connect the Load: Connect the positive and negative terminals of the DC load to the corresponding load terminals on the controller.
After all connections are made, the controller's LCD display should illuminate, indicating proper power-up.
5. Operating Instructions
5.1 LCD Display and Buttons
The controller features an LCD display for real-time system status and parameters, along with buttons for navigation and settings adjustment.
- SELECT Button: Used to cycle through display screens and menu options.
- ENTER Button: Used to confirm selections or enter parameter editing mode.
Refer to the detailed user manual (available for download from the manufacturer's website) for a complete guide on LCD navigation and parameter settings.
5.2 Battery Type Selection
It is crucial to select the correct battery type in the controller's settings to ensure proper charging algorithms and prevent battery damage. The Tracer4210ANG3 supports various battery types, including:
- Sealed (SLD)
- Gel
- Flooded (FLD)
- Lithium (LI)
- User-defined (for custom parameters)
Access the battery settings via the LCD menu and select the type that matches your connected battery bank. For Lithium batteries, ensure the correct voltage and charging parameters are set, especially if using user-defined settings.

Download the official EPEVER app from your device's app store, connect to the controller via Bluetooth, and follow the in-app instructions for monitoring system data and adjusting parameters.
6. Maintenance
Regular maintenance ensures optimal performance and longevity of your solar charge controller:
- Check Connections: Periodically inspect all wiring connections for tightness and corrosion. Tighten any loose connections.
- Clean the Controller: Keep the controller clean and free of dust and debris. Use a dry cloth for cleaning. Do not use liquids.
- Ventilation: Ensure that the ventilation openings are not blocked to allow for proper heat dissipation.
- Battery Inspection: Regularly check your battery bank for signs of damage, corrosion, or electrolyte levels (for flooded batteries).
7. Troubleshooting
If you encounter issues with your Tracer4210ANG3 controller, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Controller display is off. | No power from battery or solar panel; reversed battery polarity. | Check battery connections and voltage. Ensure solar panels are receiving sunlight. Verify battery polarity. |
| Battery not charging. | Solar panel not connected; low solar input; incorrect battery type setting; faulty wiring. | Check solar panel connections and ensure sufficient sunlight. Verify battery type setting. Inspect all wiring. |
| Load not working. | Load disconnected; battery voltage too low; load overcurrent protection activated. | Check load connections. Allow battery to charge. Reduce load or check for short circuits. |
| Overheating warning. | Poor ventilation; excessive ambient temperature; overloaded system. | Ensure adequate airflow around the controller. Reduce load if possible. Relocate to a cooler environment. |
