The solar inverter has an insulation and grounding monitoring on the DC side. The

options can be congured in the Setup menu “S -> Solar ISO / GND” (see „8.2.7.1 Sub-

menu S: Solar ISO / GND“, page 31).

The insulation monitoring has two modes:

● ISO-ON-Error (the solar inverter is disconnected from the grid in the event of an

insulation fault)

● ISO-ON-Warning (the solar inverter indicates the fault but is not disconnected from

the grid).

Deltas solar inverters are factory-set to ISO-ON-Warning mode on delivery.

The grounding monitoring has two modes:

● PV+ grounding (grounding monitoring of the positive pole of the PV generator)

● 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 “SOLIVIA

Grounding Kit MC4” (EOE99000275). The grounding connection is monitored and

should be congured in the Setup menu (see „8.2.7 Submenu S (Setup)“, page 30).

Alternatively, it is possible to turn off the insulation- and grounding monitoring:

● ISO / GND OFF.
