8. Solució De Problemes

If you encounter issues with your EPEVER MT-50 Remote Meter, consider the following common troubleshooting steps:

• Sense pantalla/alimentació:
  • Check the communication cable connection at both the MT-50 and the solar charge controller. Ensure it is firmly plugged in.
  • Verify that the solar charge controller is powered on and functioning correctly. The MT-50 draws power from the controller.
  • Inspect the communication cable for any visible damage (cuts, kinks). Try using a different RJ45 cable if available.
• Lectures incorrectes:
  • Ensure the MT-50 is connected to the correct RS485 port on your controller.
  • Verify that the battery type and other parameters are correctly set on the MT-50 to match your system configuration.
  • Check the connections of the solar panels, battery, and load to the solar charge controller for proper wiring.
• Communication Error (COM indicator):
  • This indicates a problem with the RS485 communication. Re-check the cable and connections.
  • Ensure your solar charge controller is compatible with the MT-50.
  • Power cycle the solar charge controller (disconnect and reconnect battery/solar) to reset communication.
