5.2 MT-50 Remote Meter Operation

The MT-50 remote meter provides a more user-friendly interface for monitoring and configuring the controller. It displays real-time data for solar panel voltage/current, battery voltage/current/temperature, and load status. You can also access a menu interface to adjust various control parameters.

Setting Lithium Battery Parameters via MT-50:

To set the battery type to Lithium (User-defined) and adjust related parameters:

1. Choose 'Control Para' from the main menu.
2. Press 'OK' to enter.
3. Navigate to 'Batt. Type' and press 'OK'.
4. Use the up/down arrows to select 'User' for Lithium battery.
5. Go on to adjust specific parameters like Over Volt. Disc., Charge Limit, Boost Charge, Float Charge, Low Volt. Disc., and Discharge Limit according to your Lithium battery's specifications.
6. Finally, press 'OK' and 'Save' to apply the changes.

6. Manteniment

Un manteniment regular garanteix la longevitat i el rendiment òptim del vostre controlador de càrrega solar. Feu les comprovacions següents periòdicament:

• Inspecció visual: Check for any loose connections, damaged wiring, or signs of corrosion.
• Neteja: Keep the controller and its terminals clean and free from dust and debris. Use a dry cloth for cleaning.
• Ventilació: Ensure that the controller's heat sink is not obstructed and has adequate airflow for proper cooling.
• Parameter Check: Periodically verify that the battery charging parameters are correctly set, especially after any system changes or power outages.

7. Solució De Problemes

If you encounter issues with your EPEVER solar charge controller, consider the following common troubleshooting steps:

• Sense pantalla/alimentació: Check all battery connections and ensure the battery voltage is within the controller's operating range. Verify the fuse (if external) is intact.
• Sense càrrega: Confirm solar panel connections are secure and receiving adequate sunlight. Check PV voltage on the display. Ensure battery voltage is not already at full charge.
• La càrrega no funciona: Check load connections and ensure the load is not exceeding the controller's maximum current rating. Verify the load control mode is set correctly (e.g., manual ON).
• Codis d'error: Refer to the controller's user manual for specific error codes displayed on the LCD or MT-50 and their corresponding solutions.
• Problemes de temperatura: Ensure the temperature sensor is properly connected and placed near the battery for accurate readings.
