Fronius Symo Hybrid 3.0-3-S - Status Codes - Class 6 (Service Intervention Required)

Code Description Behaviour Remedy
558,
559
Functional incompatibility
(one or more PC boards in
the inverter are not compat-
ible with each other, e.g. after
a PC board has been
replaced)
Warning message on
the display
Update inverter firmware; *)
560
Power derating caused by
overfrequency
Displayed when grid
frequency becomes
excessively high. The
power is reduced.
As soon as the grid frequency is
back within the permissible range
and the inverter has returned to
normal operation, the fault is recti-
fied automatically; **)
567 Power derating caused by
overvoltage
Displayed when grid
voltage becomes
excessively high. The
power is reduced.
As soon as the grid voltage is back
within the permissible range and
the inverter has returned to normal
operation, the fault is rectified auto-
matically; **)
573 Power derating caused by
excessively low temperatures
When power derating
occurs, a warning mes-
sage is shown on the
display.
Fault rectified automatically; **)
*) If the status code is displayed all the time: notify a Fronius-trained service engineer
**) If this status code keeps recurring, contact your system engineer.
Status codes –
Class 6

engineer.
Code Description Behaviour Remedy
601 CAN bus is full The inverter is not feeding
any energy into the grid.
Update inverter firm-
ware; *)
603 DC module temperature sensor faulty The inverter will automat-
ically attempt to connect
again and, if possible, will
resume feeding energy
into the grid.
*)
608 Functional incompatibility (one or more
PC boards in the inverter are not com-
patible with each other, e.g. after a PC
board has been replaced)
The inverter is not feeding
any energy into the grid.
Update inverter firm-
ware; *)
*) If the status code is displayed all the time: Notify a Fronius-trained service engineer.
**) Fault is rectified automatically. If this status code keeps recurring, contact your system
engineer.
Status codes –
Class 7
Class 7 status codes relate to the control system, the configuration and inverter data
recording, and may directly or indirectly affect the process of feeding energy into the grid.
