After the power loss of the grid, the bus voltage
drops to the sudden frequency decreasing point and
the inverter begins to decrease the running
frequency at P11.02 to make the inverter generate
power again. The returning power can maintain the
bus voltage to ensure a rated running of the inverter
until the recovery of power.

Note:
1. Adjust the parameter properly to avoid the
stopping caused by inverter protection during
the switching of the grid.
2. Disable input phase loss protection to enable
this function.
