Event number Message, cause and corrective measures
1407
Grid fault
Disconnection from the utility grid due to non-compliance with the voltage-frequency ratio at
line conductor Lxx
Corrective measures:
1408
Grid fault
AC sources in the system are driving the generator. The reverse power in the generator has
been exceeded for too long.
Corrective measures:
1409
Grid fault
The Sunny Island disconnects from the utility grid at line conductor L1 / L2 / L3 due to pro-
hibited feedback at phase L1 / L2 / L3.
Corrective measures:
1410
Grid fault
The feed-in current at line conductor L1 / L2 / L3 is higher than the set maximum value (pa-
rameter Maximum current from public grid).
Corrective measures:
1411
Grid fault
External current at L1 / L2 / L3 exceeds the value set for parameter Maximum current
from public grid or Rated generator current by 2%.
Corrective measures:

• Contact the Service (see Section 19, page 189).
• Adjust the generator request to the properties of the AC sources in the system and the
loads, e.g., for PV inverters, preferably request the generator at night.
• If the generator can absorb reverse power, adjust the settings for reverse power (see
Section 7.8.1.4, page 97).
• Contact the Service (see Section 19, page 189).
• Contact the Service (see Section 19, page 189).
• Reduce power consumption of all loads.
• Reduce power output of the AC sources (e.g. PV inverter).
