Status codes –
Class 6 Some of the class 6 status codes necessitate intervention by a Fronius-trained
service engineer.
Code Description Behaviour Remedy
601 CAN bus is full The inverter is not feed-
ing any energy into the
grid.
Update inverter firm-
ware; *)
603 DC module temperature sensor
faulty
The inverter will auto-
matically 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 compatible with each other, e.g.
after a PC board has been re-
placed) The inverter is not feed-
ing any energy into the
grid.
Update inverter firm-
ware; *)
*) If the status code is displayed all the time: Notify a Fronius-trained service en-
gineer.
**) Fault is rectified automatically. If this status code keeps recurring, contact
