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 
identied, the PV status will be displayed as
Not connected. The PV string access type can be 
identied 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.
