connected to the Battery Pack (see inverter manual at www.SMA-
Solar.com).
• Ensure that the plug contacts of the power cable and the data cable
are not damaged.
9311
Battery cell overvoltage fault
The voltage of at least one cell is outside the threshold.
Corrective measures:

tures from 0°C to 40°C.
Corrective measures:
• Ensure that the permitted ambient temperatures are complied with at
the installation site.
• If this message is displayed even though the permitted ambient
temperature is complied with, contact the SMA Service Line.

tures from 0°C to 40°C.
Corrective measures:
• Ensure that the permitted ambient temperatures are complied with at
the installation site.
• If this message is displayed even though the permitted ambient
temperature is complied with, contact the SMA Service Line.
