Area of application

The SOLIVIA grounding kit can only be used with Delta solar inverters of the following types SOLIVIA 2.5
AP G3, SOLIVIA 3.0 AP G3, SOLIVIA 3.3 AP G3 and SOLIVIA 5.0 AP G3 as well as with SOLIVIA 2.5 EU
G4 TR, SOLIVIA 3.0 EU G4 TR, SOLIVIA 3.3 EU G4 TR, SOLIVIA 3.6 EU G4 TR, SOLIVIA 5.0 EU G4 TR
and SOLIVIA 11 EU G4 TR. On these inverters, HF transformers are used to electrically isolate the DC input
(generator side) from the AC output (mains side). Positive or negative grounding of the PV generator is only
permitted for transformer inverters.

Safety and warning notices

Make sure that the PV generator (PV modules and cables) has been set up with protective insulation (safety
class II).
Read the operation and installation manual for the grounding kit and the Delta solar inverter carefully. Compli-
ance with all prescribed safety regulations, technical supply conditions set out by the relevant utility and all
applicable regulations is mandatory.

Mode of operation and description

Some manufacturers of thin-film and back-contact PV modules require the PV generator to be grounded at the
positive or negative pole. This is intended to compensate the effects of ageing and degradation caused by ionic
migration and charging.
Attention: Using the SOLIVIA grounding kit to earth an initially ungrounded PV generator will disable its insula-
tion monitoring. In other words, an important protection function is removed from the PV installation.
The SOLIVIA grounding kit can be used for either positive or negative generator grounding. Positive grounding
is recommended for PV module with back-contact solar cells. Negative grounding is recommended for thin-film
modules (CdTe, CIS, aSi).
Please refer to the technical specifications sheet of the PV module manufacturer for details on grounding
requirements for the modules.
