4. Setup and Installation

Follow these steps for proper installation of your EPEVER MPPT Solar Charge Controller. Ensure all power sources are disconnected before beginning.

4.1 Connection Sequence

1. Connect the Battery: First, connect the battery to the controller. Ensure correct polarity (positive to positive, negative to negative). The controller will automatically detect the system voltage (12V/24V).
2. Connect the Load: Next, connect the DC load to the controller.
3. Connect the Solar Panel: Finally, connect the solar panel to the controller. Ensure correct polarity.

Important: Always follow the connection sequence: Battery → Load → Solar Panel. Disconnect in the reverse order: Solar Panel → Load → Battery.

4.2 Temperature Sensor Connection

Connect the remote temperature sensor to the designated port on the controller. This allows the controller to accurately measure battery temperature and apply temperature compensation for optimal charging.

4.3 RS485 Communication Port

The RS485 communication port allows connection to the MT50 remote meter, PC software, or other monitoring devices. If the RS485 communication port is not in use, ensure the waterproof cap is securely installed to prevent water ingress.

5. Operating Instructions

Once properly installed, the controller will begin operating automatically. The LED indicators provide status information.

5.1 LED Indicators

The controller features LED indicators to show its operational status:

• Charging LED indicator: Indicates the charging status of the battery.
• Battery LED indicator: Shows the battery's state of charge.

5.2 Remote Meter MT50

The MT50 remote meter provides real-time operational data, fault information, and allows for parameter settings. Refer to the MT50 user manual for detailed instructions on its use.

6. Maintenance

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

• Periodically inspect all wiring and connections for signs of wear, corrosion, or looseness. Tighten any loose connections.
• Keep the controller clean and free from dust and debris. While waterproof, excessive buildup can affect heat dissipation.
• Ensure the area around the controller is well-ventilated to facilitate heat dissipation.
• Check the battery terminals for corrosion and clean them if necessary.
• Monitor the system's performance regularly using the MT50 remote meter or monitoring software.
