Undervoltage test
After the overvoltage test, the inverter performs 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 electricity grid.
Once the inverter has disconnected from the electricity grid, the display alternates between the
following values:
• Disconnection value,
• Calibration value,
• Reaction time,
• Current line voltage.
