22 Operation and installation manual SOLIVIA 5.0 EU G3
The fi rst line shows the limits according the standard. The second line shows the actual measured
grid frequency and the test status, positive (pass) or negative (fail). Pressing the test is confi rmed
and the auto-test routine continue. If no is pressed, the result is shown for 1minute. After this
time, the result is confi rmed automatically.
If has been pressed the display shows, for example:
L: 49.70 Hz LFT
A: 49.99 Hz RUN
The limit “L:” will increase till crossing the actual measured grid frequency “A:”. Reached this condi-
tion the inverter disconnects from grid and the display shows, for example:
L: 49.99 Hz 0.044 S
A: 49.99 Hz LF pass
If the test is confi rmed, the auto-test routine is fi nished. The display shows, for example:
Autotest Passed
Esc to continue
First line shows the actual auto-test status. If all the single test are passed and confi rmed, the actual
auto-test status will be passed. Pressing “ESC” the display goes back to the main menu.
If the actual auto-test status is failed, pressing “ESC” the display goes back to the main menu and
the inverter is in error condition. The display shows “ AUTOTEST FAILED”. If the actual status is
failed it’s possible to restart the auto-test routine. If the auto-test permanently fails please contact
the customer service.
If during the auto-test is performed any grid or inverter errors occurs, the auto-test routine is aborted
and the display shows the actual failed auto-test status. The inverter reset and perform a restart if
the previous status was passed.
The auto-test can be started only if the inverter is in normal operating conditions. It is not possible
to entry the auto-test routine if the grid is not in the defi ned tolerances, if any internal inverter error
occurs or the solar plan do not respect the specifi cations.
A restart of the inverter will be done after the auto-test, when the result of the current auto-test is
different from the result from the auto-test before.
While the auto-test routine is ongoing, green LED is fl ashing, the red shows isolation measurement
status and the yellow shows the status of last auto-test (yellow on: last auto-test was failed; yellow
off: last auto-test was ok).
