12.3 Error messages

No display in the event of insufficient DC voltage
It is only possible to take measurements and display messages when there is sufficient DC
voltage.
The text line on the display shows the relevant display messages whenever an error occurs. The event
numbers for the displayed error messages appear above the text line. If the error persists for a
prolonged period, the red LED lights up and the fault indicator is activated (if connected).
In addition, depending on the type of disturbance, the
"spanner" or "telephone receiver" symbol on the display
light up.
• Spanner: signifies a disturbance that can be
remedied on site.
• Telephone receiver: signifies a device disturbance.

Installation Manual
Cause and corrective measures
The mains voltage has exceeded the permissible range. This
error can have the following causes:
• The mains voltage at the termination point of the inverter
is too high.
• The grid impedance at the termination point of the inverter
is too high.
The inverter disconnects itself from the electricity grid for safety
reasons.
Corrective measures:
• Check the mains voltage and grid connection on the
inverter.
If the mains voltage is outside the permissible range due
to local grid conditions, ask your network operator if the
voltage can be adjusted at the feed-in point or if it would
be acceptable to change the monitored operating limits.
If the mains voltage is within the tolerance range, yet this
error is still displayed, contact the SMA Service Line.
