Configuration Options
There are 4 different configuration options for the "PowerBalancer" parameter.
• FaultGuard
This operating mode allows for the implementation of a three-phase grid voltage monitoring,
which also reacts to device disturbances.
– If one of the 3 inverters indicates a grid voltage fault and stops feeding in, the other two
inverters also disconnect from the power distribution grid immediately.
– If one of the 3 inverters indicates a device fault and stops feeding in, the other two inverters
also disconnect from the power distribution grid 5 minutes later.
Local connection requirements
Select the respective setting and always observe the local connection requirements and
provisions of your distribution grid operator!
