• FaultGuard
This operating mode allows to implement a three-phase grid voltage monitoring that also reacts
to device failures.
– If one of the three inverters indicates a grid voltage fault and stops feeding in, the other
two inverters also disconnect from the grid immediately.
– If one of the three inverters indicates a device fault and stops feeding in, the other two
inverters also disconnect from the grid 5 minutes later.
