BP SERIES Inverter can detect the anti-islanding situation by Phase Jump Detection Method. In case of phase-
angle jumping detection, the inverter will block the gating signal in a presised setting-time. During the time of
blocking gating signal, if the grid voltage and grid frequency is recovered within the normal operation range,
the inverter will be restart. BP SERIES inverter is monitored each 10 cycle. If the phase-angle error exceeds the
pre-set phase angle during {PJD Trip Time}, inverter will block the gating signal.
