Questions and answers
Bonjour j'ai un problème avec le nouveau INVT XG30KTR , nous n'arrivons pas à le démarrer il affiche sur le tableau RUNNING error; F 31-03; GIRD EN 50549 , qu'est ce qu'on doit faire?
To resolve the RUNNING error F 31-03 on the INVT XG30KTR inverter:
1. Check the LCD for the fault code and refer to Table 8-1 for its definition.
2. Stop the inverter:
- Disconnect the AC breaker to isolate the inverter from the grid.
- Turn off the built-in DC switch of the inverter.
- Turn off the external DC breaker to disconnect the PV strings.
- Wait at least 5 minutes for internal discharge.
3. Refer to the troubleshooting section (Section 8) to identify and fix the cause of the fault.
4. After clearing the fault, follow Section 5 to reconnect and restart the inverter.
