The text line on the display shows the relevant display messages whenever an error occurs. The event
numbers for the displayed error messages will appear in the text line. By tapping on the enclosure lid,
you can scroll through multi-line messages.
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 failure.
Contact the SMA Service Line.

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 triggering 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.
