Cause of warning and inverter's behavior Maintenance or
3-phase monitoring: One of the three
inverters connected together with I2I link has
an incorrect 3-phase monitoring configuration
compared to the other two inverters.
3-phase monitoring: One of the inverters
connected to the AC grid phases is faulty and
has disconnected from the grid. The
remaining operating inverters continue
operation according to the 3-phase
monitoring setup, parameter 75.08, until the
faulty inverter has been serviced.
3-phase monitoring: One of the inverters
connected to the AC grid phases has sensed
instability of the 3-phase supply and has
disconnected from the grid. The remaining
operating inverters continue operation
according to the 3-phase monitoring setup,
parameter 75.06, until the unstable phase
becomes functional again.
3-phase monitoring: Communication timeout
of I2I link between 3-phase configured
inverters has occurred. The inverter
continues operation according to the 3-phase
monitoring setup, parameter 75.04.
Troubleshooting 109
service person
actions
User should check
and compare the 3-
phase monitoring
parameter settings
between all three
inverters connected
together with I2I link.
User should inform the
system supplier about
the warning and
perform corrective
actions according to
their instructions.
User should check the
serial number of the
faulty inverter and
immediately contact
the system supplier
about the warning to
organize a service visit
for the faulty inverter.
User should monitor
for 10 minutes or so
whether the inverter
returns to normal
operation
automatically or not. If
not, or if the warning
repeats often, the user
should immediately
contact the system
supplier.
