2 – Fault, Red in colour

3 – EFI, Orange in colour

Normal Operation Mode

As long as no LED or only the green LED is on, the Inverter is in its normal operating status. If the green LED is flashing, the inverter is in its initializing phase which is a normal operating state as well. All other signals indicate a disturbed operating state. Refer to the inverter manual for more information on the different LED signal codes.

Normal Operation Mode
As long as no LED or only the green LED is blinking, the Sunny Boy is in its normal operating status. If all three LEDs are on, the inverter is in its initializing phase which is a normal operating state as well. All other signals indicate a disturbed operating state. Refer to the inverter manual for more information on the different LED signal codes.

Earth Fault / Insulation FailureIndicates an earth fault of one of the two thermally monitored varistors on the DC input side is defective. In this condition feeding to the utility grid is suspended, until the failure is rectified.
1: Off

2: Off

3: On

Inverter permanently disabledFailure of the grid monitoring or the independent disconnection device (MSD) within the unit. During the internal testing process, the inverter has detected a malfunction of the MSD and has stopped feeding to the grid. This is a failure which cannot be rectified on site.
