W 331 AntiIsl 1 Undesired stand-alone grid
is present at connection 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 generator:
This may be caused by a contactor between
the generator and the Sunny Island.
•
Control 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 SMA Service Line.
W 332 AntiIslSlv1 1 Undesired stand-alone grid
is present at connection AC2
of slave 1.
W 333 AntiIslSlv2 1 Undesired stand-alone grid
is present at connection AC2
of slave 2.
W 335 ExtVtgRdtErr 1 The voltage of the generator
or the utility grid at the
master is outside the
configured thresholds
(redundant measurement).
Corrective measures for a generator:
•
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 SMA Service Line, if required.
W 336 ExtVtgRdtErrSlv1 1 The voltage of the generator
or the utility grid at slave 1 is
outside the configured
thresholds (redundant
measurement).
W 337 ExtVtgRdtErrSlv2 1 The voltage of the generator
or the utility grid at slave 2 is
outside the configured
thresholds (redundant
measurement).
W 339 ExtVtgIncPro 1 Voltage increase protection •
Ensure that the conductor cross-section of
the AC cables is correctly sized.
