Operating Manual
Level Cause
1 Disconnection from the ex-
ternal grid due to too low
frequency at line conduc-
tor L1: The frequency of the
generator or the utility grid at
the master is too low.
1 Disconnection from the ex-
ternal grid due to too low
frequency at line conduc-
tor L2: The frequency of the
generator or the utility grid at
slave 1 is too low.
1 Disconnection from the ex-
ternal grid due to too low
frequency at line conduc-
tor L3: The frequency of the
generator or the utility grid at
slave 2 is too low.
1 Disconnection from the ex-
ternal grid due to too high
frequency at line conduc-
tor L1: The frequency of the
generator or the utility grid at
the master is too high.

10 Troubleshooting
Corrective measures
Corrective measures for a genera-
tor:
• 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 Service, if required (see
Section 16 "Contact", page 161).
