I PV String Access Detection
Function
● PV string access detection applies to large-scale commercial and utility-scale
PV plants with PV strings facing the same direction.
● In AC or DC power limiting scenarios:
– If the PV access type is not identied, the PV status will be displayed as
Not connected. The PV string access type can be identied only when
the inverter restores to the non-power limiting state and the current of
all connected PV strings reaches Startup current.
– After setting parameters, you can view the string access status on the
Running Info screen.
Procedure
Step 1 Log in to the FusionSolar app and choose Me > Device commissioning. The
Device commissioning screen is displayed.
Step 2 Choose Maintenance > PV string access detection. The parameter setting screen
