SMA SUNNY ISLAND 6.0H - External Frequency and Stand-alone Grid Errors

SMA Solar Technology AG 9 Troubleshooting
Operating Manual SI60H-80H-BE-en-20 51
W 323 ExtFrqLo 1 Frequency at terminal AC2
of the master is too low.
Corrective measures for a generator:
• The generator may be overloaded.
Reduce the total power of the loads by
staggering their use over time.
•
Adjust the limiting values for generator
frequency on the Sunny Island (see
installation manual of the Sunny Island).
Observe and analyze the measured
values 134.04 ExtFrq during operation.
•
Adjust the frequency of the external
energy source.
Corrective measures for a utility grid:
• Contact the SMA Service Line if required.
W 324 ExtFrqLoSlv1 1 Frequency at terminal AC2
of slave 1 is too low.
W 325 ExtFrqLoSlv2 1 Frequency at terminal AC2
of slave 2 is too low.
W 327 ExtFrqHi 1 Frequency at terminal AC2
of the master is too high.
W 328 ExtFrqHiSlv1 1 Frequency at terminal AC2
of slave 1 is too high.
W 329 ExtFrqHiSlv2 1 Frequency at terminal AC2
of slave 2 is too high.
W 331 AntiIsl 1 Undesired stand-alone grid
is present at terminal AC2 of
the master.
•
Ensure that the insulated wires at terminal
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.
•
Implement control of the contactor via a
Sunny Island 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 terminal AC2 of
slave 1.
W 333 AntiIslSlv2 1 Undesired stand-alone grid
is present at terminal AC2 of
slave 2.
W 335 ExtVtgRdtErr 1 Voltage at terminal AC2 of
the master is outside the
configured limiting values
(redundant measurement).
Corrective measures for a generator:
•
Adjust the limiting values for voltage of
the generator on the Sunny Island (see
installation manual of the Sunny Island).
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 at terminal AC2
of slave 1 is outside the
configured limiting values
(redundant measurement).
W 337 ExtVtgRdtErrSlv2 1 The voltage at terminal AC2
of slave 2 is outside the
configured limiting values
(redundant measurement).
