2. Safety Precautions
Adhering to these safety guidelines is crucial for preventing damage to the controller, batteries, and other components, as well as ensuring personal safety.
- When wiring the controller, ensure the circuit breaker or fuse is open (off) and that the leads of the positive (+) and negative (-) poles are connected correctly. Incorrect polarity can cause severe damage.
- A fuse, with a current rating 1.25 to 2 times the rated current of the controller, must be installed on the battery side. This fuse should be located no more than 150 mm from the battery terminal.
- For installations in areas prone to frequent lightning strikes or unattended locations, an external surge arrester must be installed to protect the system.
- If an inverter is part of your system, connect the inverter directly to the battery terminals. Do not connect the inverter to the load side of the controller.
- Ensure proper ventilation around the controller to prevent overheating.

5. Setup and Installation
5.1 Wiring Diagram
The following diagram illustrates a typical wiring setup for the EPEVER Tracer-AN series solar charge controller in a solar power system. Ensure all connections are secure and correctly polarized.
Figure 3: System wiring diagram for the Tracer-AN controller.
5.2 Connection Order
It is critical to connect the components in the correct sequence to prevent damage to the controller and other system components:
- Connect the Battery: First, connect the battery to the controller's battery terminals. Ensure correct polarity (+ to +, - to -).
- Connect the Solar Panel: Next, connect the solar panel(s) to the controller's PV terminals. Verify correct polarity.
- Connect the Load: Finally, connect your DC loads to the controller's load terminals.
5.3 Battery Type Setting
The controller is compatible with various battery types. You must select the correct battery type for optimal charging and battery longevity. The MT50 remote meter or PC software can be used to configure this setting.
Figure 4: Supported Battery Types and their default settings.
CAUTION:
When the default battery type (Sealed, Gel, Flooded) is selected, the battery voltage control parameters will be set by default and cannot be changed. To customize these parameters, you must select the "User" battery type.
6. Operating Instructions
6.1 MT50 Remote Meter
The MT50 remote meter provides a convenient interface for monitoring and controlling your solar system. It allows for:
- Real-time data monitoring of PV input, battery status, and load output.
- Remote load switch control.
- Browsing and modification of device parameters, charging control parameters, and load control parameters.
6.2 RS485 Communication
The RS485 communication port allows you to connect the controller to a PC or other monitoring equipment. Using the provided RS485 cable and EPEVER software, you can:
- Monitor the solar charging system's data in real-time.
- Set and adjust various system parameters.
6.3 Temperature Sensor (RTS)
The RTS (Remote Temperature Sensor) is essential for accurate battery charging. It acquires the battery's ambient temperature, allowing the controller to perform temperature compensation for control parameters. This ensures optimal charging voltage and current, prolonging battery life. The standard length of the RTS cable is 3 meters.
7. Maintenance
Regular maintenance ensures the longevity and optimal performance of your solar charge controller and overall system:
- Inspect Connections: Periodically check all wiring connections for tightness and corrosion. Loose connections can lead to power loss and overheating.
- Clean the Controller: Keep the controller clean and free from dust, dirt, and debris. Use a dry cloth to wipe the exterior. Ensure ventilation openings are not blocked.
- Check Ventilation: Verify that the controller has adequate airflow around it, especially around the heat dissipation aluminum alloy (see Figure 5).
- Monitor System Performance: Regularly check the readings on the MT50 remote meter or PC software to ensure the system is operating within expected parameters.
