Corrective measures
W 331 AntiIsl
1
Disconnection from the ex-
ternal grid due to undesired
stand-alone grid at line con-
ductor L1
: Undesired stand-
alone grid is present at connec-
tion
AC2
of the master.
• Ensure that the insulated wires at
connection
AC2
are securely
connected and that the conductors
in the terminals are free of
insulation.
Corrective measures for a genera-
tor:
This may be caused by a contactor be-
tween the generator and the Sunny Is-
land.
• Control of the contactor via a
Sunny Island inverter multifunction
relay. Set the parameter of the
multifunction relay, e.g.,
241.01 Rly1Op
, to
AutoGn
.
• Set the parameter
234.20
GdAiSns
to a lower sensitivity.
Corrective measures for a utility
grid:
• Contact the Service, if required (see
Section 16 "Contact", page 161).
W 332 AntiIslSlv1
1
Disconnection from the ex-
ternal grid due to undesired
stand-alone grid at line con-
ductor L2
: Undesired stand-
alone grid is present at connec-
tion
AC2
of slave 1.
W 333 AntiIslSlv2
1
Disconnection from the ex-
ternal grid due to undesired
stand-alone grid at line con-
ductor L3
: Undesired stand-
alone grid is present at connec-
tion
AC2
of slave 2.
W 335 ExtVtgRdtErr
1
Disconnection from external
source due to exceeding the
configured thresholds in the
device at L1
: The voltage of
the generator or the utility grid
at the master is outside the con-
figured thresholds (redundant
measurement).
Corrective measures for a genera-
tor:
• Adjust the thresholds for generator
voltage on the Sunny Island (see
the Sunny Island inverter installation
manual). Observe and analyze the
measured values
134.02 ExtVtg
during operation.
• If possible, adjust the generator
voltage.
Corrective measures for a utility
grid:
• Contact the Service, if required (see
Section 16 "Contact", page 161).
W 336 ExtVtgRdtErrSlv1
1
Disconnection from external
source due to exceeding the
configured thresholds in the
device at L2
: The voltage of
the generator or the utility grid
at slave 1 is outside the config-
ured thresholds (redundant mea-
surement).
W 337 ExtVtgRdtErrSlv2
1
Disconnection from external
source due to exceeding the
configured thresholds in the
device at L3
: The voltage of
the generator or the utility grid
at slave 2 is outside the config-
ured thresholds (redundant mea-
surement).
