Undervoltage Test
After the overvoltage test, the inverter proceeds to carry
out the undervoltage test. During the test sequence, the
current calibration value of the voltage limit applied is
shown in the display of the inverter.
The voltage is increased step by step until the
disconnection threshold is reached and the inverter
disconnects from the power distribution grid.
Once the inverter has disconnected from the power distribution grid, the display successively shows
the following values:
• Disconnection value,
• Calibration value,
• Reaction time,
• Current line voltage.
