AUTOTEST procedure in accordance with standard CEI 0-21
The autotest according to the grid standard CEI-021 can be launched via
the menu on the display.
The conditions required to perform an Autotest are:
• The grid standard must be set to CEI-021.
• You must not intervene in any way while the test is underway
• You must check that the equipment has a stable network connection.
Running the tests from the display menu
In the Autotest section of the SETTINGS menu, select the type of test the
equipment is to run from the following:
OV Test – parameters:
U>>; U>; U> (10Min)
Disconnection from the distribution grid due to “Over-voltage”
UV Test – parameters:

Go to the SETTINGS > Autotest menu
If one of the protections is disabled (from the Service menu), N/A (not
applicable) will appear next to the name of the test.
While one of the tests is being performed, the set limits will be gradually
increased/reduced (depending on the type of test) until the threshold at
which the inverter is disconnected from the grid is reached. The procedu-
res for running the Autotest comply with the legislation in force.
The display shows the message “Performing Test” when the test has
