Message, cause and corrective measures
1416
Grid incident
Due to a voltage imbalance between the line conductors, the system discon-
nects from the utility grid.
Corrective measures:
• Eliminate any faults in the installation.

DC overvoltage > Disconnect PV array
Overvoltage at the DC input. This can destroy the inverter.
This message is signalized additionally by rapid flashing of the LEDs.
Corrective measures:
•
Immediately
disconnect the inverter from all voltage sources.
• Check whether the DC voltage is below the maximum input voltage of
the inverter. If the DC voltage is below the maximum input voltage of the
inverter, reconnect the DC connectors to the inverter.
• If the DC voltage exceeds the maximum input voltage of the inverter,
ensure that the PV array has been correctly rated or contact the installer
of the PV array.
• If this message is repeated frequently, contact Service.

3503
Ground fault > Check PV array
The inverter has detected a ground fault in the PV array.
Corrective measures:
• Check the PV system for ground faults.
3601
High leakage current > Check PV array
The leakage current of the inverter and the battery is too high. There is a
ground fault, a residual current or a malfunction.
The inverter interrupts parallel grid operation immediately after exceeding a
threshold. When the fault is eliminated, the inverter automatically reconnects
to the utility grid.
Corrective measures:
• Check the battery and DC cabling for ground faults.
