If the bus voltage drops to the sudden
frequency decreasing point due to the
Frequency power loss of the grid, the inverter begins
to decrease the
at sudden according to
power loss power generation state. The regenerative
power can maintain the bus voltage to
ensure normal running of the inverter
until the recovery of power.
