Status Diagnostics And Troubleshooting; Displaying Status Codes; Total Failure Of The Display; Class 1 Status Codes - Fronius Agilo 75.0-3 Operating Instructions Manual

Status diagnostics and troubleshooting

Displaying status The inverter performs a system self diagnosis that automatically detects many faults that
codes may occur and shows them on the display. This means you are promptly made aware of
malfunctions in the inverter and the photovoltaic system, or of any installation or operating
faults.
If the system self diagnosis has detected a specific fault, the associated status code will be
shown on the display.
IMPORTANT! Status codes may sometimes appear briefly as a result of the inverter's con-
trol response. If the inverter then continues working with no sign of any problem, this
means that there was no fault.

codes
The initial response of the inverter in this case is to disconnect itself from the grid. The grid
is subsequently checked for the stipulated monitoring period. If no further problem has
been detected by the end of this period, then the inverter will resume feeding energy into
the grid.
Depending on the country setup, the SoftStart-function GPIS is activated:
after cutting out due to an AC fault, the output power of the inverter is continuously in-
creased by 10% every minute in line with the VDE-AR-N 4105 guideline.

Check the AC voltage ON the inverter connections:
the AC voltage must be 230 V (+ 10 % / - 5 %)*.
The mains voltage tolerance depends on the country setup
Following careful testing and when the grid conditions are within
the permissible range again, the inverter will resume feeding
energy into the grid.
