The text lines on the display show the relevant messages whenever an error occurs. The event numbers
for the displayed error messages will appear in the text lines. By tapping on the enclosure lid, you can
scroll through multi‑line messages.
If the error persists for a long period of time, the red LED begins to glow 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 fault that can be remedied
on‑site.
• Telephone receiver: Signifies a device fault.
Contact the SMA Service Line.

1 < Grid fault >
The line voltage has exceeded the
permissible range. This error can have the
following causes:
• The grid voltage at the termination
point of the inverter is too high.
• Grid impedance at the termination
point of the inverter is too high.
The inverter disconnects itself from the
power distribution grid for safety reasons.
• Check the grid voltage and
connection on the inverter.
If the line voltage lies outside the
permissible range due to local grid
conditions, ask your grid operator if the
voltage can be adjusted at the feeding
point or if it would be acceptable to
change the monitored operational limits.
If the grid voltage lies within the tolerance
range, yet this error is still being displayed,
contact the SMA Service Line.
