Corrective measures
W 315 ExtVtgLo
1
Disconnection from the ex-
ternal grid due to undervolt-
age at line conductor L1
: The
voltage of the generator or the
utility grid at the master is too
low.
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.
• Adjust the generator voltage and/
or generator frequency.
Corrective measures in battery
backup systems:
• Contact the Service, if required (see
Section 16 "Contact", page 161).
W 316 ExtVtgLoSlv1
1
Disconnection from the ex-
ternal grid due to undervolt-
age at line conductor L2
: The
voltage of the generator or the
utility grid at slave 1 is too low.
W 317 ExtVtgLoSlv2
1
Disconnection from the ex-
ternal grid due to undervolt-
age at line conductor L3
: The
voltage of the generator or the
utility grid at slave 2 is too low.
W 319 ExtVtgHi
1
Disconnection from the ex-
ternal grid due to overvolt-
age at line conductor L1
: The
voltage of the generator or the
utility grid at the master is too
high.

tor:
• Adjust the thresholds for generator

W 320 ExtVtgHiSlv1
1
Disconnection from the ex-
ternal grid due to overvolt-
age at line conductor L2
: The
voltage of the generator or the
utility grid at slave 1 is too high.
W 321 ExtVtgHiSlv2
1
Disconnection from the ex-
ternal grid due to overvolt-
age at line conductor L3
: The
voltage of the generator or the
utility grid at slave 2 is too high.
