5.1.3 Phase Guard
This operating mode enables the implementation of three-phase grid voltage monitoring.
– If one of the 3 inverters indicates a grid voltage fault and stops feeding in, the other two
inverters also disconnect from the grid automatically.
– If one of the 3 inverters indicates a device fault and stops feeding in, the other two inverters
are not affected and continue to feed in at full power.
