● PV- grounding (grounding monitoring of the negative pole of the PV generator).
In these modes the solar inverter remains in feed-in operation and will not be discon-
nected from the grid in case of a fault. The error message “PV+ grounding fault” or “PV-
grounding fault” will appear on the display.
If you need to connect the positive or negative pole of the PV system to meet require-
ments set out by the module manufacturer, you can do this. Earth continuity must be
implemented close to the inverter. We suggest using Deltas grounding kit “Grounding
Set A Solar” (EOE99000275). The grounding connection is monitored and should be
configured in the Setup menu (see „8.3.7 Submenu S (Setup)“, page 28 ).
Alternatively, it is possible to turn off the insulation- and grounding monitoring:
● ISO / GND OFF.
