502
modules
No energy fed into the grid in
509
the past 24 hours
Unable to communicate with
515
filter
No communication possible
516
with the storage unit
Power derating caused by too
517
high a temperature
522 DC low String 1
523 DC low String 2
Functional incompatibility (one
or more PC boards in the in-
558 verter are not compatible with
each other, e.g. after a PC
board has been replaced)
Power derating caused by
560
overfrequency
566 Arc detector switched off
(e.g. during external arc moni-
toring)
Class 7 status Class 7 status codes relate to the control system, the configuration and inverter data re-
codes cording, and may directly or indirectly affect the process of feeding energy into the grid.
Code Description
Conflict when setting the in-
705 verter number (e.g. number al-
ready assigned)
EEPROM has been reinitial-
721
ised or EEPROM is faulty

Possible error displays or mal-
functions on the inverter
This status code is displayed
when the grid frequency be-
comes excessively high.
The inverter will then reduce its
output.
The status indicator will contin-
ue to be displayed until the in-
verter has returned to normal
operation.
The status code is displayed
every day until the arc detector
is reactivated.
Behaviour
-
Warning message is shown on
the display
Remedy
If this status code keeps recur-
ring, contact your system engi-
neer.
Acknowledge status code;
check whether all the condi-
tions for the problem-free feed-
ing of energy into the grid have
been met (e.g. are the solar
modules covered with snow)
If the status code is displayed
all the time: look out for further
status codes
If the status code is displayed
all the time: Notify a Fronius-
trained service technician.
Purge openings for cooling air
and heat sink if necessary;
fault is rectified automatically;
if this status code keeps recur-
ring, contact your system engi-
neer
If this status code keeps recur-
ring, contact your system engi-
neer.
If this status code keeps recur-
ring, contact your system engi-
neer.
As soon as the grid frequency
is back within the permissible
range and the inverter has re-
turned to normal operation, the
fault is rectified automatically.
If this status code keeps recur-
ring, contact your system engi-
neer.
No error
Confirm status code by press-
ing 'Enter'
Remedy
Correct the inverter number via
the Setup menu
Acknowledge status code;
If the status code is displayed
all the time: notify a Fronius-
trained service engineer
