Operation and installation manual SOLIVIA 2.5 AP G3 TR
CAuSE
Connection PV+ (PV-)
to GND is interrupted or
wrong pole is connected
to GND.
Versions of hard- and soft-
ware are not compatible.
Initialization of solar inver-
ter on start-up.
Insufficient input power.
PV generator voltage bet-
ween 100 V and 150 V.
Checks grid voltage and
grid frequency for grid
input mode.
Internal varistor at the DC
input is defective.
Enter keys on the display
are locked, if there is
no input entry within 5
minutes.
ELIMInATIOn
Check that the GND connection
has been made correctly and/or
check the fuse in the grounding
path. Change the fuse if necessary.
The solar inverter remains in feed-
in operation.
If the fault persists after the device
has been reset, please inform your
service technician.
The first time the solar inverter is
started up:
Normal function with a PV cell vol-
tage of between 100 V and 150 V.
Insufficient insolation (dawn/twi-
light).
Check the PV cell voltage via the
display in the N menu.
Insufficient insolation.
Check the PV cell voltage via the
display in the N menu.
Normal function before input mode.
Although you can, in theory, carry
on using the solar inverter, the
varistors should be replaced at
the earliest opportunity. This will
involve returning the device.
To unlock the enter keys, you need
to switch off the DC voltage and
then switch it on again.
