When errors occur, a display message including the corresponding event number will appear in the
text line of the display. By tapping on the enclosure lid, multi-line messages can be switched further.
If the error exists over a long period of time, the red LED begins to light and the multi-function relay is
switched (if available).
In addition, depending on the severity of the fault the
"wrench" or "telephone receiver" symbol on the display
will light up.
• Wrench: signifies a failure which can be remedied
on site.

Event no. Display message and cause Corrective measures
1< Grid fault >
The grid voltage has exceeded the
permissible range. This error can have the
following causes:
• The grid voltage at the point of
connection of the inverter is too high.
• Grid impedance at the terminal of the
inverter is too high.
For safety reasons, the inverter disconnects
itself from the grid.
• Check the grid current and grid
connection on the inverter.
If the grid voltage lies outside the
acceptable range because of local grid
conditions, ask the utility provider if the
voltage can be adjusted at the feed-in point
or if it would agree to changes in the values
of the monitored operational limits.
If the grid voltage lies within the tolerance
range, yet this error is still being displayed,
contact the SMAServiceline.
