Class 4 Status
Codes Class 4 status codes may require the intervention of a trained Fronius service technician.
305 No feed-in despite closed relay Short interruption of grid power
feed operation.
The inverter returns to the
startup phase.
**)
306
There is insufficient PV power for grid
power feed operation
Short interruption of grid power
feed operation.
The inverter returns to the
startup phase.
Wait for sufficient solar
radiation;
**)
307
DC low
DC input voltage is too low for grid
power feed operation
IMPORTANT! Status codes 306 (Power low) and 307 (DC low) appear naturally every morning and evening due
to low solar irradiance. These status codes are not the result of a fault.
308
Intermediate circuit voltage too high
Short interruption of grid power
feed operation.
The inverter returns to the
startup phase.
**)
309 DC input voltage MPPT1 too high
311 DC strings polarity reversed
313 DC input voltage MPPT2 too high
314 Timeout current sensor calibration
Short interruption of grid power
feed operation.
The inverter returns to the
startup phase.

315 AC current sensor fault
316 InterruptCheck fail
325 Overtemperature in connection area
326 Fan 1 error
327 Fan 2 error
Code Description Behavior Remedy
Code Description Behavior Remedy
401 Communication with power module is
not possible
The inverter will automati-
cally attempt to connect
again and, if possible, re-
sume feeding energy into
the grid
*)
406 AC module temperature sensor faulty
(L1)
407 AC module temperature sensor faulty
(L2)
408 Direct component measured in the sup-
ply grid too high
412 The "fixed voltage" setting has been se-
lected instead of MPP voltage operation
and the voltage is set to a value that is
too low or too high.
- **)
415 Safety cut-out triggered by option card or
RECERBO Inverter does not feed ener-
gy into the grid. *)
416 No communication between power mod-
ule and control unit The inverter will automati-
cally attempt to connect
again and, if possible, re-
sume feeding energy into
the grid
