Overvoltage Test
The inverter begins with the overvoltage test. During the
test sequence, the voltage limit applied is shown in the
display of the inverter.
The voltage limit is reduced successively until the
disconnection threshold is reached and the inverter
disconnects from the grid.
Once the inverter has disconnected from the grid, the
display successively shows the following values one after the other:
•Disconnection value,
•Calibration value,
•Reaction time,
• Present grid voltage.
