Para phase loss
Phase losing in parallel system
Confirm that the wiring of the inverter is
correct. If the Master is set to 3-phase
Master, the number of parallel inverters
must be ≥3. (The grid input for each in-
verter should be connected correctly to
Grid L1, L2, L3.) If the Master is set to 2x
208 Master, the number of parallel invert-
ers needs to be ≥2. (And the grid input of
each inverter should be connected cor-
rectly to Grid L1, L2, L3.)
Para no BM set Master is not set in the parallel system
Set one of the inverters in the parallel sys-
tem as the Master.
Para multi BM
set
Multiple Primaries have been set in
parallel system
There are at least two inverters set as the
Master in the parallel system. Keep one
Master and set the other as Slave.
