codes restrict it. These status code are displayed until they are acknowledged by pressing a key
(the inverter, however, continues to operate normally in the background).
Code Description
Insulation error on the solar
502
modules
No energy fed into the grid in
509
the past 24 hours
No communication with filter
515
possible
No communication possible
516
with the storage unit
Power derating caused by too
517
high a temperature
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)
Behaviour
Warning message is shown on
the display
Warning message is shown on

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 engineer
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
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.
