Event number
Display message, cause and corrective measures
1501
Reconnection fault grid
The changed country data set or the value of a parameter you have set does
not correspond to the local requirements. The inverter cannot connect to the
utility grid.
Corrective measures:
• Ensure that the country data set has been configured correctly. Check the
setting of the rotary switches A and B or select the operating parameter
Set country standard and check the value.
3301 to 3303
Unstable operation
The ten-minute average value of the grid voltage is no longer within the per-
missible range. The grid voltage or grid impedance at the connection point is
too high. The inverter disconnects from the utility grid to maintain power qual-
ity.
Corrective measures:
• Check whether the grid voltage at the connection point of the inverter is
permanently in the permissible range.
If the grid voltage is outside the permissible range due to local grid
conditions, contact the grid operator. The grid operator must agree with
an adjustment of the voltage at the feed-in point or with a change of the
monitored operating limits.
If the grid voltage is permanently within the permissible range and this
message is still displayed, contact Service (see Section 15, page 43).
3401 to 3402
DC overvoltage > Disconnect generator
Overvoltage at the DC input. This can destroy the inverter.
This message is additionally highlighted by rapid flashing of the backlight.
Corrective measures:
• Immediately disconnect the inverter from all voltage sources (see
• 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 (see Section 15,
