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 shut-
down threshold is achieved 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,
• Current grid voltage.
