• FaultGuard
This operating mode allows for the implementation of a three‑phase line voltage monitoring,
which also reacts to device faults.
– If 1 of the 3 inverters indicates a line voltage fault and stops feeding in,
the other 2 inverters also disconnect from the power distribution grid immediately.
– If 1 of the 3 inverters indicates a device fault and stops feeding in,
the other 2 inverters also disconnect from the power distribution grid 5 minutes later.
