EPEVER Tracer-AN Series MPPT Solar Charge Controller

1. Introduction

The EPEVER Tracer-AN series solar charge controller is designed for efficient and reliable management of solar power systems. Utilizing advanced Maximum Power Point Tracking (MPPT) technology, it optimizes energy harvesting from solar modules, improving energy utilization by 10%-30% compared to traditional PWM charging methods. This controller features a common negative design and an intuitive LCD for displaying operational status.

It supports both lead-acid and lithium-ion batteries and incorporates a three-stage charging mode for extended battery life. The controller includes comprehensive electronic protection functions to minimize damage from incorrect installation or system failures, ensuring safer and more reliable operation of your solar power supply system.

Important Safety Note: When wiring the controller, do not close the circuit breaker or fuse until all connections are secure. Ensure that the leads of the positive (+) and negative (-) poles are connected correctly. A fuse, with a current rating 1.25 to 2 times the rated current of the controller, must be installed on the battery side, no more than 150 mm from the battery. If the controller is used in an area with frequent lightning strikes or an unattended area, an external surge arrester must be installed. 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.

• System Performance: Monitor the system's performance via the MT50 or PC software to detect any deviations from normal operation.

9. Troubleshooting

If you encounter issues with your EPEVER Tracer-AN controller, consider the following common troubleshooting steps:

• No Display/Power: Check battery connections and ensure the battery voltage is within the controller's operating range. Verify the fuse on the battery line.
• No Charging: Ensure solar panels are connected correctly and receiving sufficient sunlight. Check PV voltage on the display. Verify that the battery type setting is correct.
• Load Not Working: Check load connections and ensure the load current does not exceed the controller's rating. Verify load control settings (e.g., timer, manual switch).
• Abnormal Readings: Ensure the Remote Temperature Sensor (RTS) is properly connected and placed. Check communication cable connections for the MT50 or PC.
