Installation and Wiring

Proper installation and wiring are crucial for the safe and efficient operation of your solar charge controller. Please follow these guidelines carefully.

Wiring Diagram

This diagram illustrates the correct connection sequence: 1. Battery, 2. Load, 3. PV Array. Disconnect in reverse order.

Important Cautions

• CAUTION: When wiring the controller, do not close the circuit breaker or fuse. Ensure that the positive ("+") and negative ("-") leads are connected correctly.
• CAUTION: A fuse, with a current rating 1.25 to 2 times the controller's rated current, must be installed on the battery side. The distance from the battery should not exceed 150 mm.
• CAUTION: If the controller is used in an area with frequent lightning strikes or is an unattended area, an external surge arrester must be installed.
• CAUTION: If an inverter is to be connected to the system, connect the inverter directly to the battery, not to the load side of the controller.

Operation

Maintenance

To ensure optimal performance and longevity of your EPEVER MPPT solar charge controller, regular maintenance is recommended.

• Periodically inspect all wiring connections to ensure they are secure and free from corrosion.
• Keep the controller clean and free from dust and debris. Ensure proper ventilation around the unit.
• Monitor the LCD display for any error codes or unusual readings. Refer to the troubleshooting section if issues arise.
• Ensure the ambient temperature around the controller remains within its specified operating range to prevent overheating.

Troubleshooting

This section provides guidance for common issues you might encounter with your solar charge controller.

• Controller Not Charging: Check PV array connections, ensure sufficient sunlight, verify battery connections, and check for blown fuses. Confirm that the PV input voltage is within the controller's operating range.
• Low Charging Current: Inspect PV panel cleanliness, check for shading, and confirm battery type settings are correct. Ensure all connections are secure and there is no excessive voltage drop.
• LCD Display Not Working: Verify battery connection and voltage. Ensure the controller is receiving power. If the issue persists, contact support.
• Load Output Off (Over-Discharge Protection): If the load output is off, the battery voltage may be too low. The load will automatically reconnect once the battery recovers to a safe voltage level.
• Overheating: Ensure the controller has adequate ventilation and is not installed in an enclosed space without airflow. Reduce load if necessary.
