Operation and installation manual SOLIVIA 2.5 AP G3
CAUSE
Display communication
faulty.
Grid frequency overshoo-
ting or undershooting
specified limit range.
Grid voltage overshooting
or undershooting specified
limit range.
One of the anti-islanding
protection output relays is
faulty / defective.
Check internal settings.
DC component of input-
side alternating current is
too high.
Internal communication
error or hardware fault.
The device trips and
reverts to grid input mode
once the temperature has
dropped.
Isolation resistance fault
on the DC side during
start-up phase (# 508) or
running phase (# 506).
Isolation resistance fault
on the DC side during
start-up phase or running
phase.
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.
ELIMINATION
- If the fault persists after the device has
been reset, please inform your service
technician.
- Check the grid frequency via the
display in the N menu.
- Check the grid voltage via the display in
the N menu.
- If no voltage present, check grid auto-
matic circuit breaker.
- The solar inverter is defective.
- Return the device.
Normal function before input mode.
- If the fault persists after the device has
been reset, please inform your service
technician.
- If the fault persists after the device has
been reset, please inform your service
technician.
- Check the installation site (no direct
sunlight, air circulation).
- Check the isolation resistance on the DC
side of the PV modules.
- You must check the isolation resistance
on the DC side of the PV modules.
Solar inverter is still feeding!
- 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 voltage
of between 100 V and 150 V.
- Insufficient insolation (dawn/twilight).
- 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.
