Corrective measures:
• If this message is displayed frequently, contact the
SMA Service Line.

The mains voltage is no longer within the permissible range. The
inverter has disconnected from the electricity grid for safety reasons.
This can be caused by one of the following:
• The miniature circuit-breaker is switched off.
• The AC cable is interrupted.
• The AC cable is highly resistive.
Corrective measures:
• Ensure that the AC cable is correctly connected.(see section
6.3.2 "Connecting the Inverter to the Electricity Grid", page 35)
• Ensure that the mains voltage is in the permissible range.
• Ask the network operator for permission to change the
parameters
Uac-Min
and
Uac-Max
.
If the AC cable is connected correctly, the mains voltage is within the
permissible range and this message is still displayed, contact the
SMA Service Line.

Overvoltage at DC input
The inverter may be destroyed.
Corrective measures:
• Disconnect the miniature circuit-breaker.
• Remove the ESS.
• Unlock and remove all DC connectors. To do so, insert a slotted
screwdriver (blade width: 3.5 mm) into one of the side slots and
pull the DC connectors straight down.
DO NOT PULL ON THE
CABLE
whilst doing this.
• Ensure that the DC voltage is in the permissible range.
• If the DC voltage is above the maximum input voltage of the
inverter, check the PV plant design or contact installer of the
PV array.
• If the DC voltage is below the maximum input voltage of the
inverter, connect the DC connectors to the inverter again.
• If this message is repeated frequently, disconnect the inverter
(see section 9) and contact the SMA Service Line.
