This operating mode allows for the implementation of three-phase mains voltage monitoring.
– If one of the three inverters indicates a mains voltage fault and stops feeding in, the other
two inverters also disconnect from the electricity grid automatically.
– If one of the three inverters indicates a device fault and stops feeding in, the other two
inverters are not affected and continue to feed in at full power.
