Cause and corrective measures
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
parameter Set country standard and
check the value.
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
irradiation. The inverter interrupts the feed-in
operation.
Corrective measures:
• Wait for higher irradiation.
• If this event recurs at medium irradiation
levels, check the PV system design and the
correct circuitry of the PV array.
Overvoltage at the 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 10).
• Check whether the DC voltage is below the
maximum system voltage of the inverter.
If the DC voltage is below the maximum
system voltage of the inverter, reconnect
the DC connectors to the inverter.
• If the DC voltage is above the maximum
system 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.
