Code Description Behaviour Remedy
313 Battery input voltage too high. Short-term interruption
while feeding energy into
the grid.
The inverter repeats its
startup routine. This ser-
vice code may occur
sporadically even though
there is no actual fault. Switch on, connect
or check battery;

Short-term interruption
while feeding energy into
the grid.
The inverter repeats its
startup routine. Purge cooling air
openings and heat
sink; **)
*) If the status code is displayed all the time: Notify a Fronius-trained service technician.
**) Fault is rectified automatically. If this status code keeps recurring, contact your system fitter
Status codes –
Class 4
Some of the class 4 status codes necessitate intervention by a Fronius-trained
service engineer.
Code Description Behaviour Remedy
401 Unable to communicate with the
power stage set
The inverter will auto-
matically attempt to
connect again and, if
possible, will resume
feeding energy into the
grid.

faulty (PV)
407 AC module temperature sensor
faulty
408 DC component measured in the
grid too high
412 Fixed voltage mode has been selec-
ted instead of MPP voltage mode,
and the fixed voltage has been set
to too low or too high a value.

415 Safety cut-out via option card or
RECERBO has triggered
The inverter is not feed-
ing any energy into the
grid.

416 No communication possible
between power stage set and con-
trol system.
The inverter will auto-
matically attempt to
connect again and, if
