AC current limitation Line
conductor L1
: The power of
the loads is too high for the mas-
ter.
• Ensure that the Sunny Island is
functional. For this, clean the fans
and restart the Sunny Island (see
Section 11.7, page 95).
• Ensure that there are no short
circuits in the system and that the
power of the loads is not greater
than the power of the Sunny Island
inverter.
• Use a star delta electronic circuit to
start three-phase loads with a high
start-up electricity demand (e.g.,
engines).
• Connect the loads with very high
power directly to the generator
whenever possible. Ensure that the
generator is not overloaded.

AC current limitation Line
conductor L2
: The power of
the loads is too high for slave 1.
W 119 AcCurLimSlv2
1
AC current limitation Line
conductor L3
: The power of
the loads is too high for slave 2.
F 121 InvVtgHi
3
Inverter overvoltage Line
conductor L1
: An overvoltage
has occurred at connection
AC1
of the master.
• Ensure that the Sunny Island is
functional. For this, disconnect all
AC sources and loads from the
Sunny Island and restart the
Sunny Island.
• Find the cause of the overvoltage
through measurement and step-by-
step connection of the AC sources
and loads.
W 122 InvVtgHiSlv1
1
Inverter overvoltage Line
conductor L2
: An overvoltage
has occurred at connection
AC1
of slave 1.
W 123 InvVtgHiSlv2
1
Inverter overvoltage Line
conductor L3
: An overvoltage
has occurred at connection
AC1
of slave 2.
F 129 InvFrqHi
3
Inverter overfrequency Line
conductor L1
: An overfre-
quency has occurred at connec-
tion
AC1
of the master.
• Ensure that the Sunny Island is
functional. For this, disconnect all
AC sources and loads from the
Sunny Island and restart the
Sunny Island.
• Find the cause of the overfrequency
through measurement and step-by-
step connection of the AC sources
and loads.

W 131 InvFrqHiSlv2
1
Inverter overfrequency Line
conductor L3
: An overfre-
quency has occurred at connec-
