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:
Use stainless steel bolt and washer to bond the ground
wire and aluminum frame through the grounding hole
(see figure 7A and 7B). Please consider the below bolt
types and tightening torques:

Additional third-party grounding devices:
AEG solar modules can be grounded using third-party
grounding devices. It is required that these devices are
certified for grounding solar modules and are installed
according to the manufacturer's instructions.

4. MAINTENANCE

4.1 General mainteance

If any problem arises, have them investigated by
a competent specialist; repairing works must be
performed by specialized and properly trained
personnel only. Improper maintenance can cause lethal
electric shock and/or burns.
Use appropriate safety equipment (insulated
tools, insulating gloves, etc.) when handling
modules.
