Code
Description
LOW PV POWER
Intermediate circuit voltage
306
has dropped below permissible
threshold value for grid power
feed operation.
LOW PV VOLTAGE
DC input voltage has dropped
307
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
DC input voltage for MPPT 1
309
too high
313
DC input voltage for MPPT 2
too high
Class 4 Status
Class 4 status codes may require the intervention of a trained Fronius service technician.

voltage operation and the volt-
age is set to a value that is too
low or too high.

416
power stage set and control
unit
417
ID problem with hardware
419

Possible hardware defect
428
Details
Brief interruption of grid power
feed operation.
The inverter returns to the
Startup phase.
Brief interruption of grid power
feed operation.
The inverter returns to the
Startup phase.
Details
The inverter will automatically
attempt to connect again and,
if possible, resume grid power
feed operation.
-
Inverter does not feed energy
into the grid.
The inverter will automatically
attempt to connect again and,
if possible, resume grid power
feed operation.
Rectification
The fault is rectified automati-
cally.
If this status code keeps recur-
ring with sufficient solar irradi-
ance, contact your system
installer.
Error is automatically rectified;
if status code persists: contact
a Fronius-trained service tech-
nician.

nician.
If this status code keeps recur-
ring, contact your system in-
staller.
