Class 5 Status Class 5 status codes generally do not impair grid power feed operation, but can lead to lim-
Codes itations in grid power feed operation. They will be displayed until the status code is ac-
knowledged by pressing a key (the inverter, however, continues working normally in the
background).
Code Description
Insulation error on the solar
502
modules
No feed-in within the last 24
509
hours
515 No internal communication
with filter
516 Communication with memory
unit not possible
Power derating due to exces-
517
sive temperature
Function incompatibility (one
or more PC boards in the in-
558 verter are not compatible with
each other, e.g., after PC
board replacement)
Power derating due to over-fre-
560
quency
566 Arc detector switched off
(e.g., with external arc moni-
toring)

Warning message of memory
unit
If a power derating occurs, a
warning message is shown on
the display.
Possible error displays or mal-
functions in the inverter.
The status code is displayed
with excessive grid frequency.
The inverter reduces the pow-
er.
The status indicator is dis-
played until the inverter re-
sumes normal operation.
The status code is displayed
every day until the arc detector
is activated again.
Rectification
Check MPP settings;
If status code persists:
contact a Fronius-trained ser-
vice technician.
Carry out AC reset (switch au-
tomatic circuit breaker off and
on);
If status code persists:
contact a Fronius-trained ser-
vice technician.
Rectification
If this status code keeps recur-
ring, contact your system in-
staller.
Acknowledge status code;
check if all conditions for fault-
free grid power feed operation
are fulfilled (e.g., if the solar
modules are covered with
snow).
If the status code persists: ob-
serve further status codes.
If status code persists: Contact
a Fronius-trained service tech-
nician
If required, clean cool air vents
and cooling elements with
compressed air.
The fault is rectified automati-
cally.
If this status code keeps recur-
ring, contact your system in-
staller.
If this status code keeps recur-
ring, contact your system in-
staller.
As soon as the grid frequency
returns to the permissible
range and the inverter re-
sumes normal operation, the
error is rectified automatically.
If the status code persists,
contact your system installer.
No error!
Confirm status code displayed
by pressing the "Enter" key.
