4. Setup and Installation

4.1 Mounting the Controller

The controller should be mounted vertically on a flat, non-flammable surface in a well-ventilated area, away from direct sunlight and heat sources. Ensure there is sufficient space around the controller for air circulation.

• The mounting holes have a diameter of 5mm.
• Refer to the dimensions in the specifications section for precise mounting.

4.2 Wiring Connections

Follow these steps for wiring the EPEVER Tracer 3210 AN controller. Always ensure power is off before making any connections.

1. Connect the Battery: Connect the battery to the controller's battery terminals. Ensure correct polarity (+ to + and - to -). The controller will automatically detect the system voltage (12V/24V).
2. Connect the Solar Panels: Connect the solar panels to the controller's PV input terminals. Ensure correct polarity. The maximum PV input voltage is 100V.
3. Connect the Load (Optional): If using the load output, connect your DC load to the controller's load terminals.
4. Connect the Temperature Sensor: Plug the temperature sensor (TS-R) into the designated port on the controller. This allows for accurate battery temperature compensation.
5. Connect the MT-50 Remote Meter: Connect the MT-50 remote meter to the RJ45 communication port on the controller using the provided cable.
6. Power On: Once all connections are secure, you can power on your solar system.

Important Note: Always connect the battery first and disconnect it last. Failure to follow this order may damage the controller.

5. Operating Instructions

5.1 Basic Operation via LCD Display

The LCD display and buttons (SELECT, ENTER) allow you to monitor system status and adjust parameters.

• SELECT Button: Used to cycle through different display screens and menu options.
• ENTER Button: Used to confirm selections or enter parameter editing mode.
• Monitoring: Press SELECT to view various system parameters like PV voltage, battery voltage, charging current, and load status.
• Parameter Setting: To change a parameter, navigate to the desired setting, press ENTER to enter editing mode, use SELECT to change the value, and press ENTER again to confirm.

5.2 Battery Type Selection

The controller supports various battery types. It is crucial to select the correct battery type for optimal charging and battery life.

• Supported types include Sealed, Gel, Flooded, AGM, and Lithium batteries.
• For lead-acid batteries (Gel, Sealed, Flooded), you can select the type directly on the controller or via the MT-50.
• For Lithium batteries or custom user settings, you must use the PC software or the mobile app to configure the parameters.

5.3 Load Control Modes

The controller offers practical load control modes:

• Manual Control: Turn the load on/off manually.
• Test Mode: For testing purposes.
• Light Control Mode: Load turns on/off based on ambient light levels.
• Light Control + Timer Mode: Load turns on based on light levels and stays on for a set duration.

5.4 Remote Monitoring (MT-50 / PC Software / APP)

The MT-50 remote meter provides a convenient way to monitor and adjust controller parameters from a distance. For more advanced monitoring and parameter customization, connect the controller to a PC via an RS485 to USB cable or use the EPEVER mobile app (requires an eBox-WIFI-01 or eBox-BLE-01 adapter).

6. Maintenance

Regular maintenance ensures the optimal performance and longevity of your solar charge controller.

• Cleanliness: Keep the controller clean and free from dust and debris. Use a dry cloth for cleaning.
