Error 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 con-
nect 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
permissible range. The grid voltage or grid impedance at the connection
point is too high. The inverter disconnects from the utility grid to comply
with the power quality.
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 the SMA Service Line.
3401 to 3402 DC overvoltage > Disconnect generator
Overvoltage at DC input. This can destroy the inverter.
This message is additionally highlighted by rapid flashing of the back-
light.
Corrective measures:
• Immediately disconnect the inverter from all voltage sources (see
Section 2.3, page 8).
• 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 is above 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 displayed frequently, contact the
SMA Service Line.
