Status Diagnosis and Troubleshooting

Displaying Sta- Your inverter is equipped with a self diagnostic system that automatically identifies a large
tus Codes number of possible operation issues by itself and displays them on the screen. This en-
ables you to know immediately if there are any malfunctions in the inverter, the photovoltaic
system or any installation or operating errors.
Whenever the self diagnostic system has identified a particular issue, the respective status
code is shown on the screen.
IMPORTANT! Status codes may sometimes appear briefly as a result of the control re-
sponse from the inverter. If it subsequently continues to operate normally, there has not
been a system error.
Total Failure of If the display remains dark for a long time after sunrise:

Class 1 Status Status codes in class 1 are typically temporary. Their cause lies in the grid.
Codes
Your inverter's first reaction is to disconnect from the grid. Thereafter, the grid will be
checked for the duration of the observation period stipulated. If, after the end of this period,
no further defect is identified, your inverter resumes grid power feed operation.

check the AC voltage at the inverter's connections:
the AC voltage must be 208–240 V (+10% / -12%) according to the grid.

Grid conditions are being test-
ed and as soon as they are
back within the permissible
range, the inverter will resume
grid power feed operation.
