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