11.2 Error messages
The text line on the display shows the relevant display messages whenever an error occurs. Two-digit
event numbers corresponding to the displayed messages are shown above the text line, and
three-digit or four-digit event numbers in the text line directly in front of the display message. You can
scroll down multi-line messages by tapping on the lower enclosure lid.
If the error exists over a long period of time, the red LED lights up and the multi-function relay is
activated.
In addition, depending on the severity of the disturbance
the "spanner" or "telephone receiver" symbol on the
display will light up.
• Spanner: signifies a disturbance which can be
remedied on-site (see table below).
• Telephone receiver: signifies device disturbance.

101 …
103 < Grid fault >
The line voltage has exceeded the
permissible range. This error can have the
following causes:
• The line 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 from the electricity
grid for safety reasons.
• Check the line voltage and grid
connection on the inverter.
If the line 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 line voltage is within the tolerance
range, yet this error is still displayed,
contact the SMA Service Line.

203 < Grid fault >
The line voltage has fallen below the
permissible range. This error can have the
following causes:
• Electricity grid disconnected
• AC cable damaged
• The line voltage at the termination
point of the inverter is too low.
The inverter disconnects from the electricity
grid for safety reasons.
• Check the tripping of the miniature
circuit-breaker.
• Check the line voltage and grid
connection on the inverter.
If the line 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 line voltage is within the tolerance
range, yet this error is still displayed,
contact the SMA Service Line.
