7.4.5 Self-test (only Italy)
During the self-test, the inverter tests its shutdown behaviour
with regard to too high / too low grid voltage and frequency
(7 test sections, approx. 40 minutes).
You will start the self-test by pressing "SET" longer. While the
self-test is running, the measured values are shown on the dis-
play.
If the self-test has been successful, you can exit the menu by pressing "SET".
If a measured value lies outside of the required tolerance, the self-test aborts.
The "Self-test failed" message displayed has to be confirmed by pressing "SET". The, the
self-test has to be repeated as soon as possible.
If not all the required conditions for performing the self-test have been met, an error mes-
sage appears on the display:
Message
Cause
Remedy
MSD not ready
The self-test does not start
because the inverter is not
operational
Repeat the self-test later,
when the inverter is feeding
in
An error was detected
The self-test does not start
because an internal error is
present
If this error occurs
repeatedly, inform the
installer
Invalid grid conditions
Self-test abort due to
invalid network conditions,
e.g. in the event of an AC
voltage that is too low
Repeat the self-test later
Not enough sunlight
Self-test does not start or
aborts due to the fact that
the solar radiation is too
low, e.g. in the evening or
at night
Repeat the self-test when
there is sufficient solar
radiation
If the self-test could not be run successfully, the inverter does no longer feed
in.
►
Repeat self-test as soon as possible.
The results of the self-test stored in the inverter can be shown on the display
in "Information" > "Self-test".
