Cause and corrective measures
The power frequency is not within the permissible
range. The inverter has disconnected from the
electricity grid.
Corrective measures:
• As far as possible, check the power frequency
and observe how often fluctuations occur.
If there is a high number of fluctuations and this
message is displayed frequently, contact the
network operator and ask whether they approve
a change of the operating parameters of the
inverter.
If the network operator approves, discuss any
changes to the operating parameters with the
SMA Service Line.
The inverter has detected an excessively high
proportion of direct current in the line current.
Corrective measures:
• Check the grid connection for direct current.
• If this message is displayed frequently, contact
the network operator and check whether it is
possible to raise the limiting value for monitoring
on the inverter.
