After the power loss of the grid, the bus voltage drops
to the sudden frequency-decreasing point, the
inverter begin 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. Prohibition of input phase loss protection can
enable this function.
