3.3 LED Indicators
The controller features LED indicators to provide real-time status information. Refer to the table below for their meanings:
| Indicator | Color | Status | Instruction |
|---|---|---|---|
| PV | Green | On Solid | PV connection normal but low voltage (irradiance) from PV, no charging |
| Green | OFF | No PV voltage (night time) or PV connection problem | |
| Green | Slowly Flashing | In charging | |
| BATT | Green | On Solid | Normal |
| Green | Slowly Flashing | Full | |
| Green | Fast Flashing | Over voltage | |
| Orange | On Solid | Under voltage | |
| Red | On Solid | Over discharged | |
| Red | Fast Flashing | Battery Overheating / Low Temperature | |
| Charging/green and battery indicator/orange flashing simultaneously | System voltage error |
4. Operating the MT50 Remote Meter
The MT50 remote meter allows for monitoring and setting parameters of the charge controller. It connects via the COM cable to the controller.

4.1 Basic Monitoring
Once connected, the MT50 will display real-time system data, including PV voltage, battery voltage, charge current, and load status. Use the navigation buttons (Up/Down/Left/Right) to scroll through different monitoring pages.
4.2 Load Control
From the monitoring page, you can typically toggle the load on or off by pressing the "OK" button when the load icon is highlighted. This allows for manual control of connected DC devices.
4.3 Setting Battery Parameters
To optimize charging for your specific battery type, you can set various parameters through the MT50. This is especially important for Lithium batteries, as they do not automatically identify system voltage.
- Choose "Control Para" from the main menu.
- Press "OK" to enter.
- Press "OK" again to confirm.
- Set parameters such as Battery Type (e.g., Sealed, Gel, Flooded, User) and Battery AH. For User-defined Lithium batteries, select 12V or 24V for your system.
- Press "OK" to save your settings.
Note: Please set the parameters under the guidance of professionals, especially for Lithium battery systems, to prevent damage to your batteries or system.

4.4 Load Working Mode Settings
The controller supports various load working modes. To set these parameters:
- Navigate to "Load Set" in the menu.
- Select your desired working mode: Manual Control, Light ON/OFF, Light ON+Timer, or Time Control.
- Refer to the detailed setting instructions in the main manual (Pages 21-23) for specific configurations of each mode.

5. Maintenance
Regular maintenance ensures the longevity and optimal performance of your charge controller:
- Cleanliness: Keep the controller and its terminals clean and free from dust and debris.
- Connection Checks: Periodically inspect all wiring connections to ensure they are tight and secure. Loose connections can lead to overheating and poor performance.
- Ventilation: Ensure adequate airflow around the controller to prevent overheating, especially in hot environments.
- Battery Inspection: Regularly check your batteries for any signs of damage, corrosion, or electrolyte levels (for flooded batteries).
6. Troubleshooting
If you encounter issues with your EPEVER MPPT Charge Controller, consider the following common problems and solutions:
- No Power/Display: Check all wiring connections, especially the battery connection, for proper polarity and tightness. Ensure the battery has sufficient voltage.
- Battery Not Charging: Verify solar panel connections and ensure sufficient sunlight. Check PV voltage and current on the MT50. Confirm battery parameters are correctly set for your battery type.
- Load Not Working: Check load connections and ensure the load is not overloaded. Verify the load control setting on the MT50 (e.g., not set to OFF or a timer mode that is currently inactive).
- "Save Failed" Error on MT50: This can sometimes occur due to communication issues or loose cable connections. Ensure the MT50 cable is securely connected to both the controller and the meter. Try tightening the plastic screw connectors on the cable.
- Over-charging/Under-charging: Review your battery type and charging parameters on the MT50. Ensure they match your battery manufacturer's recommendations. For Lithium batteries, manually select the correct system voltage (12V or 24V).
- System Voltage Error: This indicates a mismatch or issue with the detected system voltage. Double-check all connections and ensure the battery voltage is within the controller's operating range.
If the issue persists after attempting these troubleshooting steps, please contact EPEVER customer support for further assistance.
