Class 4 Status
Codes
Class 4 status codes may require the intervention of a trained Fronius service technician.
306
LOW PV POWER
Intermediate circuit voltage
has dropped below permissible
threshold value for grid power
feed operation.
Brief interruption of grid power
feed operation.
The inverter returns to the
Startup phase.
The fault is rectified automati-
cally.
If this status code keeps recur-
ring with sufficient solar irradi-
ance, contact your system
installer.
307
LOW PV VOLTAGE
DC input voltage has dropped
below permissible threshold
value for grid power feed oper-
ation.
IMPORTANT! Status codes 306 (LOW PV POWER) and 307 (LOW PV VOLTAGE) appear naturally every
morning and evening due to low solar irradiance. These status codes are not the result of a fault.
308 Intermediate circuit overvolt-
age
Brief interruption of grid power
feed operation.
The inverter returns to the
Startup phase.
Error is automatically rectified;
if status code persists: contact
a Fronius-trained service tech-
nician.
309
DC input voltage for MPPT 1
too high
313 DC input voltage for MPPT 2
too high

401
No internal communication
with power stage set.
The inverter will automatically
attempt to connect again and,
if possible, resume grid power
feed operation.
If status code persists: contact
a Fronius-trained service tech-
nician.
406
Power stage set temperature
sensor defective
407
Internal temperature sensor
defective
408 DC feed-in detected
412
The "fixed voltage" setting has
been selected instead of MPP
voltage operation and the volt-
age is set to a value that is too
low or too high.

If this status code keeps recur-
ring, contact your system in-
staller.
415
Safety cut-out has been trig-
gered by option card or RE-
CERBO
Inverter does not feed energy
into the grid.
If status code persists: contact
a Fronius-trained service tech-
nician.
416
No communication between
power stage set and control
unit
The inverter will automatically
attempt to connect again and,
if possible, resume grid power
feed operation.
417 ID problem with hardware
419 Unique ID conflict
421 HID range error
425
Communication with the power
stage set is not possible
426 -
428
Possible hardware defect
