W 315 ExtVtgLo 1 The voltage of the generator
or the utility grid at the
master is too low.
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 in battery backup
systems:
• Contact the SMA Service Line, if required.
W 316 ExtVtgLoSlv1 1 The voltage of the generator
or the utility grid at slave 1 is
too low.
W 317 ExtVtgLoSlv2 1 The voltage of the generator
or the utility grid at slave 2 is
too low.
W 319 ExtVtgHi 1 The voltage of the generator
or the utility grid at the
master is too high.
W 320 ExtVtgHiSlv1 1 The voltage of the generator
or the utility grid at slave 1 is
too high.
W 321 ExtVtgHiSlv2 1 The voltage of the generator
or the utility grid at slave 2 is
too high.
W 323 ExtFrqLo 1 The frequency of the
generator or the utility grid at
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 thresholds for generator
frequency on the Sunny Island (see the
Sunny Island inverter installation
manual). 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 The frequency of the
generator or the utility grid at
slave 1 is too low.
W 325 ExtFrqLoSlv2 1 The frequency of the
generator or the utility grid at
slave 2 is too low.
W 327 ExtFrqHi 1 The frequency of the
generator or the utility grid at
the master is too high.
W 328 ExtFrqHiSlv1 1 The frequency of the
generator or the utility grid at
slave 1 is too high.
W 329 ExtFrqHiSlv2 1 The frequency of the
generator or the utility grid at
slave 2 is too high.
