Message Description Remedy
An error was detected
An internal error prevented the
self test from starting.
Contact your installer if this
error occurs frequently.
Invalid grid conditions
The self test was cancelled due
to invalid grid conditions, e.g.
due to insufficient AC voltage.
Repeat the self test later.
MSD not ready
The self test was not started
because the inverter was not
ready for operation.
Repeat the self test a few min-
utes later when the inverter is
ready for operation and is
feeding.
Not enough sunlight
The self test was not started or
was cancelled due to insuffi-
cient sunlight, especially in the
evening / at night.
Repeat the self test during the
day when the inverter is
feeding the grid.
