OV Test
During this test, the limit set for the maximum grid voltage (AC) is reduced gradually
until reaching the threshold for which the disconnection of the inverter from the
distribution grid occurs.
At the end of the test, when the inverter has disconnected itself from the grid, the test
result will be shown on the display:
Pressing the ESC key will allow you to return to the Autotest menu, from which you
can select another test.
