H PV String Access Detection
Description
● 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 inverters restore 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
