The red digital tube display provides real-time operational data. Use the navigation buttons (PRG/ESC, RD/WT, arrow keys) and the RUN/STOP buttons to control the inverter and adjust parameters as needed. Consult the full manual for detailed parameter settings.

7.2 Automatic Operation (Photovoltaic Mode)

The Eujgoov VFD Solar Inverter is designed for automatic operation based on solar input:

Low Voltage Protection: The inverter will trigger a low voltage alarm and cease operation if the input voltage from the solar panels drops below 200V.
Over Voltage Suppression: When the input voltage reaches 400V, the inverter automatically regulates the voltage to prevent over-voltage shutdown, protecting the system.
Morning Startup: As light intensity increases in the morning and the input voltage reaches approximately 400V (or 200V for the photovoltaic inverter), the unit automatically initiates operation to drive the connected load without manual intervention.
Evening Shutdown: Conversely, as light intensity decreases in the evening and the input voltage drops to approximately 400V (or 200V for the photovoltaic inverter), the unit automatically stops driving the load, again without requiring manual operation.

7.3 Important Operational Notes

For optimal solar energy conversion efficiency, it is recommended to maintain the DC input voltage within the specified range of DC200-400V.
Never connect both AC input and DC input switches simultaneously. Doing so will cause irreparable damage to the inverter or the solar panel array.

8. Maintenance

Regular maintenance ensures the longevity and optimal performance of your VFD Solar Inverter.

Cleaning: Periodically inspect the inverter for dust accumulation, particularly on the cooling fan and heatsink fins. Use compressed air to gently clean these components.
Connection Check: Routinely check all terminal connections to ensure they are tight and secure. Loose connections can lead to poor performance or damage.
Environmental Conditions: Keep the unit free from moisture, excessive humidity, and corrosive substances.
Servicing: Do not attempt to repair the unit yourself. For any issues requiring service, contact qualified technical personnel or customer support.

9. Troubleshooting

This section addresses common issues you might encounter with your VFD Solar Inverter.

9.1 Common Issues and Solutions

Inverter not starting:
- Check the DC input voltage. Ensure it is within the DC200-400V operational range.
- Verify all power and load connections are secure and correctly wired.
- Ensure sufficient solar irradiance for startup.
Low voltage alarm:
- The input voltage from the solar panels is below 200V. Wait for increased light intensity or inspect the solar panel array for issues.
Over-voltage shutdown:
- The input voltage exceeded 400V. While the inverter has built-in protection, prolonged exposure or incorrect system configuration can cause this. Review your solar panel array configuration.
No output to load:
- Check the load connections and ensure the motor/pump is functioning correctly.
- Confirm the inverter is in an operational state (not in alarm or shutdown mode).

For persistent issues or problems not listed here, please consult the detailed troubleshooting guide in the complete product manual or contact Eujgoov customer support.
