Code Description
309 Too high DC1 voltage
313 Too high DC2 voltage
Service class 4
Some of the class 4 status codes necessitate intervention by a Fronius-trained service en-
gineer.
Code Description
401 Communication error be-
tween Recerbo and power
stage set
406 Temperature sensor in DC
semiconductor module de-
fective
407 Temperature sensor on the
power stage set
408 On the inverter an unac-
ceptably high DC injection
was detected
412 Adjusted fix voltage beyond
the accessible MPP range
