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
Voltage (Voc).
Please consult rated local wiring regulations to
determine system wire size, type, and temperature
rating of conductors to be connected to module
connectors.
The maximum system voltage is 1000 volts or 1500
volts depending on the product type. Please check the
product label and datasheet accordingly.
The maximum number of series connected modules
depends on system design, the type of inverter
used and environmental conditions. Always ensure
that the modules are assembled with the appropriate
string fuse for circuit protection based on the maximum
series fuse rating of the module and local electrical
installation codes.
There is no specific limitation on the number of
modules that can be connected in parallel; the number
of modules is determined by system design parameters
such as current or power output.
To prevent the cables and the connectors from
overheating, the cross section of the cables and the
capacity of the connectors must be selected to suit the
maximum system short circuit current. The
recommended PV wire should have a cross section of
minimum 4mm

.
3.3.3 Grounding
Please refer to the respective National Electrical
Code requirements and standards for safety-related
grounding of racking system and/or module frames.
AEG PV Modules use an anodic oxidized aluminum
frame; modules should hence be connected to the
equipment grounding conductor to prevent electrical
shock.
The frame rails have pre-drilled holes marked
with a grounding sign. The grounding holes
should be used for grounding purposes only and
not for module mounting.
Grounding methods:
1) Use stainless steel M8 bolt and washer to bond
the ground wire and aluminum frame through the
grounding hole (see figure 8) with a tightening torque
of 3-7N
•
m. It is recommended to use a 4-14 mm
2
(AWG 6-12) exposed copper wire as ground wire.

2) Use of grounding clamps
We recommend the use of SolKlip Grounding
Clip Assemblies 1954381 for safety purposes. The
grounding clip assembly consists of a slider, base, and
