4. Setup and Installation
Proper installation is critical for the safe and efficient operation of your solar system. Follow the connection order carefully.
4.1 Wiring Connections
The Tracer3210AN uses common negative grounding. Ensure all connections are tight to prevent loose contacts and overheating.
Figure 4.1: Connection diagram illustrating the proper sequence for connecting the battery, load, and PV panel to the solar charge controller.
- Connect the Battery: Connect the battery to the controller's battery terminals (marked with a battery symbol). Observe polarity.
- Connect the Load: Connect the DC load to the controller's load terminals (marked with a light bulb symbol). Observe polarity.
- Connect the PV Panel: Connect the solar panel array to the controller's PV terminals (marked with a solar panel symbol). Observe polarity.
Important: Disconnect in the reverse order: PV Panel → Load → Battery.
4.2 No-Battery Mode (G3 Version)
The G3 version of the Tracer-AN series supports a "No-Battery Mode," allowing direct connection to an inverter without a battery. This mode is suitable for specific applications where immediate power conversion is required.
Figure 4.2: Illustration of the controller operating in Battery Mode (with battery) and No-Battery Mode (direct to inverter).
Warning for No-Battery Mode:
- For high-frequency inverters: PV input power > (load output power + inverter conversion efficiency + controller conversion efficiency).
- For power frequency inverters: PV input power > (load output power + inverter conversion efficiency + controller conversion efficiency × 2).
5. Operation
The controller's LCD display provides real-time system information, and the two buttons (SELECT and ENTER) allow for navigation and parameter adjustment.
5.1 LCD Display Interface
The LCD cycles through various screens displaying parameters such as PV voltage, battery voltage, charging current, load current, and energy statistics.

5.2 Setting Battery Type
The controller supports various battery types. It is crucial to select the correct battery type for optimal charging and battery longevity. The default setting is "Sealed" lead-acid battery.
To set the battery type:
- Press the "SELECT" button to navigate through the display interfaces until you reach the battery type setting screen.
- Press the "ENTER" button to enter the setting mode.
- Use the "SELECT" button to cycle through the available battery types (Sealed, Gel, Flooded, LiFePO4, Li(NiCoMn)O2, User).
- Press "ENTER" to confirm your selection.
For "User" defined battery types, detailed parameters can be set via optional accessories like MT50, WiFi adapter, BLE adapter, or PC software. Refer to the battery manufacturer's specifications for accurate user-defined parameters.

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 for cleaning.
- Connections: Periodically check all wiring connections for tightness. Loose connections can cause overheating and damage.
- Ventilation: Ensure the installation area has adequate ventilation to prevent overheating. Keep the heat sink fins clear of obstructions.
- Environmental Conditions: Verify that the operating environment remains within the specified temperature and humidity ranges.
7. Troubleshooting
This section addresses common issues you might encounter with the Tracer3210AN controller.
- No Display/Power:
- Check battery connections and ensure correct polarity.
- Verify battery voltage is within the controller's operating range (8-32V).
- No Charging:
- Ensure PV panel connections are correct and secure.
- Check PV panel voltage; it must be higher than battery voltage for charging to occur.
- Verify solar panel output under current light conditions.
- Load Not Working:
- Check load connections and ensure correct polarity.
- Verify load current does not exceed the controller's rated load current.
- Check battery voltage; if it's too low, the load output may be disconnected to protect the battery.
- Incorrect Battery Type Setting:
- Ensure the selected battery type matches your installed battery. Incorrect settings can lead to improper charging and reduced battery life. Refer to Section 5.2 for instructions on setting battery type.
For persistent issues, refer to the detailed troubleshooting guide in the full product manual or contact technical support.
