2.3.2. Grounding

Appropriate grounding of the entire PV system limits voltage surges, gives a common

reference point for the conductive parts and facilitates the operation of the overcurrent

devices. The THEIA HE-t inverters meet all relevant safety requirements and include internal

surge protection.

DANGER: Ensure correct grounding of the inverter and the PV array!

Grounding must be carried out by qualified persons only and comply with local and

national electrical regulations.

Figure 2.3.4: Ground terminals in the customer connection area

1. The DC ground terminal is

located to the right of the –

NEG terminal in the

customer connection area

and labeled GND/PE.

2. The AC ground terminal is

located in the lower right

corner of the customer

connection area and labeled

GND.

• Refer to the local and national electrical regulations for correct installation and sizing of

grounding conductors.

• Only valid for France: According to UTE C 15-712-1 a minimum cross section area of 6

mm² / 10 AWG is required for the earth wire connection.

• Follow the safety instructions and specifications from the different PV module

manufacturers regarding grounding requirements.

CAUTION: Ensure correct grounding of the conductors!

The grounded PV conductors are grounded via the DC ground terminal and must

NOT be grounded at any other point in the system, as voltage potentials can appear

and possibly damage electrical components.
