This operating mode enables the implementation of three-phase line voltage monitoring.
– If one of the 3 inverters indicates a line voltage fault and stops feeding in, the other two
inverters also disconnect from the power distribution 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.
