Status Diagnostics And Troubleshooting; Displaying Status Codes; Total Failure Of The Display; Class 1 Status Codes - Fronius Primo 3.0-1 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.

Class 1 status Class 1 status codes generally only arise momentarily and are caused by the public grid.
codes
Example: The grid frequency is too high and the inverter may not feed any energy into the
grid owing to a standard. There is nothing wrong with the device.
The initial response of the inverter is to disconnect itself from the grid. The grid is subse-
quently checked during the stipulated monitoring period. If no further problem has been de-
tected by the end of this period, then the inverter will resume feeding energy into the grid.
The GPIS SoftStart function is activated according to the country setup:
After cutting out due to an AC error, the output power of the inverter is continuously in-
creased in line with the national guidelines.
Code Description
102 AC voltage too high
103 AC voltage too low
105 AC frequency too high
106 AC frequency too low
107 No AC grid
108 Stand-alone operation detect-
ed
112 RCMU error
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
Behaviour
Following careful testing and
when the grid conditions are
within the permissible range
again, the inverter will resume
feeding energy into the grid.
