3.3 Electrical Installation and Grounding

3.3.1 General remarks

Modules electrically connected together in a series/
parallel configuration generate DC electrical energy,
which can be converted to AC by mean of a solar
inverter. When modules are connected in series, the
total voltage is equal to the sum of individual voltages.
For applications requiring high currents, photovoltaic
modules can be connected in parallel; the total current
is equal to the sum of individual currents.
The resulting PV system can then be connected to
the local utility grid system. As the policies of local
utilities and technical rules concerning the connection
of renewable energy systems to power grids vary
from region to region, please consult a qualified
system designer or integrator to design a system
compliant with the related directives. Permits are
normally required for installing a PV system and the
utility must formally approve and inspect the system
before its connection to the grid can be accepted. The
connection of the inverter to the grid needs to be done
by a competent, authorized company. The electrical
installation of the PV system must be carried out in
accordance with the respective National Electrical
Codes or applicable National Regulations.

3.3.2 Electrical installation

To avoid mismatch, power loss or damage to the PV
system, do not use different module types within the
same circuit.
The modules are fitted with two pre-assembled
sunlight resistant, isolated cable leads, which end with
PV fast connectors for the electrical connection of
the system (positive [+] and negative [-] terminals).
Connectors are Multi-Contact (MC4) or Multi-Contact
compatible (MC4-compatible). Cables and connectors
must not be removed or cut off.
Refer to the electrical parameters reported on
the label of the module when selecting the size
of the cables connecting the module strings to
the solar inverter. For electrical design considerations,
when determining component voltage ratings,
conductor current ratings, fuse sizes and the rest of
electrical hardware connected to the module strings,
the values provided on the module label or on the
related datasheet should be multiplied by a factor of
1.25 for Short Circuit Current (Isc) and Open Circuit
