Status codes –
Class 4
Some of the class 4 status codes necessitate intervention by a Fronius-trained service
technician.
Code Description Behaviour Remedy
301 Overcurrent (AC)
Short-term interruption while
feeding energy into the grid
due to overcurrent in the invert-
er.
The inverter resumes with its
start-up routine.
Fault is rectified automatically;
if this status code is displayed
all the time: notify a Fronius-
trained service engineer
302 Overcurrent (DC)
303
Power stage set overtempera-
ture
Short-term interruption while
feeding energy into the grid
due to overtemperature
The inverter resumes with its
start-up routine.
Purge openings for cooling air
and heat sink if necessary;
fault is rectified automatically;
if this status code keeps recur-
ring, contact your system engi-
neer
304 Internal temperature too high
306
LOW PV OUTPUT
Intermediate circuit voltage too
low for feeding energy into the
grid
Short-term interruption while
feeding energy into the grid
The inverter resumes with its
start-up routine.
Fault is rectified automatically;
if this status code occurs when
there is sufficient insolation,
contact your system engineer
307
LOW PV VOLTAGE
DC input voltage too low for
feeding energy into the grid
IMPORTANT! Due to the low level of insolation, the status codes 306 (LOW PV OUTPUT) and 307 (LOW PV
VOLTAGE) are displayed routinely every morning and evening. These status codes do not indicate any kind of
fault.
308 Intermediate circuit overvolt-
age
Short-term interruption while
feeding energy into the grid
The inverter resumes with its
start-up routine.
Fault is rectified automatically;
if this status code is displayed
all the time: notify a Fronius-
trained service engineer
309
DC input voltage MPPT 1 too
high
313 DC input voltage MPPT 2 too
high
Code Description Behaviour Remedy
401
Unable to communicate with
the power stage set
The inverter will automatically
attempt to connect again and,
if possible, will resume feeding
energy into the grid.
If the status code is displayed
all the time: Notify a Fronius-
trained service technician.
406
Power stage set temperature
sensor faulty
407
Internal temperature sensor
faulty
408
Direct current feeding in de-
tected
412
Fixed voltage mode has been
selected instead of MPP volt-
age mode, and the fixed volt-
age has been set to too low or
too high a value.
