11.3 Error Messages
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.
Contact the SMA Service Line.
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.
Event no. Message Cause and corrective measures
101 to
103 Grid fault 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.
