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 power distribution 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
parameter
Set country standard
and
check the value.

Unstable operation
There is not enough power at the DC input of the
inverter for stable operation. This may be caused
by snow on the PV modules or insufficient
sunlight. The inverter interrupts the feed-in
operation.
Corrective measures:
• Wait for greater irradiation.
• If this event recurs at medium irradiation
levels, check the PV plant design and the
correct circuitry of the PV array.

DC overvoltage
Disconnect generator
Overvoltage at DC input The inverter may be
destroyed.
When this message is signaled, it is
accompanied by rapid flashing of the backlight.
Corrective measures:
•
IMMEDIATELY DISCONNECT
the
inverter from voltage sources
(see Section 8).
• Check the DC voltage to ensure it 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 PV array installer.
• If this message is repeated frequently,
contact the SMA Service Line.
