Class 7 Status
Codes
Class 7 status codes concern the inverter control unit, configuration and data recording,
and can directly or indirectly affect grid feed operation.
517
Power derating due to exces-
sive temperature
If a power derating occurs, a
warning message is shown on
the display.
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.
558
Function incompatibility (one
or more PC boards in the in-
verter are not compatible with
each other, e.g., after PC
board replacement)
Possible error displays or mal-
functions in the inverter.
If this status code keeps recur-
ring, contact your system in-
staller.
560
Power derating due to over-fre-
quency
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.
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.
566 Arc detector switched off
(e.g., with external arc moni-
toring)
The status code is displayed
every day until the arc detector
is activated again.
No error!
Confirm status code displayed
by pressing the "Enter" key.
