Chapter 3 Module Electrical Connection uidelines
The electrical connection/grounding must meet related regulations/standards of the
installation site or country and must be installed by a qualified installer.
Use series or parallel connections for the design of connections between modules in
accordance with the user's requirements for system power, voltage, or current.
Each Module is equipped with a junction box and connector with a certain level of water/dust
resistance and the junction box is equipped with two cables, one positive and the other
negative. Two Modules can be connected in series by connecting the positive cable of a
connector to the negative cable of the other connector; similarly, two Modules can be
connected in parallel by connecting their positive (or negative) connectors.
Incorrect connection or loose connection may cause electric arcs or electric shocks, damage
equipment, or cause fires. Please inspect and make sure that all electrical connections are firm
and fixed (the connections of the connectors should be firmly locked in place).
The maximum voltage in series connection of modules is the total voltage of all modules.
Please note that the maximum voltage in series connection cannot exceed the Module's
maximum permissible voltage (the maximum permissible voltage of the AUO Photovoltaic
Module is 1,000 VDC, as specified on the back of the Module). Similarly, the maximum current
in parallel connection of modules is the total current of all modules.
The output and voltage of the Module will exceed the rated values when operating under low
temperatures (<25°C). Consider the lowest possible ambient temperature of the year at the
installation site and use the open-circuit voltage temperature coefficient to calculate the
maximum number of modules allowable for series connection. The reference calculation
formula is as follows:
Maximum system voltage/module open-circuit voltage * [1 + module open-circuit voltage
temperature coefficient * (lowest ambient temperature of the installation site -25)]
The electrical connection of the module/system must be conducted with a dedicated cable for
solar photovoltaic systems with minimum requirements as follows:
1. PV1-F or PV Wire cable standards
2. The cross section of the cable must be greater than 4 mm
2
(or 12AW )
3. The rated voltage of the cable must exceed 1,000 VDC
4. The cable materials must be suitable for outdoor use, insulated, and sunlight and
ultra-violet resistant.
5. The applicable temperature range of the cable must be at least -40°C to +90°C.
When connecting cables, the minimum bend radius of the cable must be greater than 5 times
the cable diameter, as illustrated in Figure 8.

13
Figure 8: The Minimum Bend Radius of the Cable
The cable may be applicable for outdoor use and resistant to ultra-violet radiation but the
cable should be protected from direct sunlight or immersion in water. When necessary,
sunlight resistant cable trays or cable ties can be used to fix the cable at suitable positions
(please avoid damage or heavy pressure on the cable during fixture).
3.1 Module rounding Method
The Module must be grounded properly to ensure the safety of personnel and the work
environment. Please connect grounding in accordance with IEC Standards or the electrical
codes and regulations of the site/country of installation to ensure that the Module is correctly
grounded.
The grounding holes on the Module frame are marked with grounding symbols (as indicated
in Figure 9; the quantity, size and position of grounding holes are different for each model;
please refer to the corresponding Module Data Sheet for detailed information). Please use
the grounding holes on the Module frame for grounding. It is strictly forbidden to drill
additional holes that may damage the frame.

14
Figure 9: Module rounding Hole Illustration. Please refer to the corresponding Module Data
Sheet for detailed quantity, size and position of grounding holes.
The components required for grounding the module shall adopt materials that are resistant to
corrosion and ultraviolet and suitable for outdoor use.
Avoid electrochemical corrosion ( alvanic corrosion) caused by contact between the Module
frame and different metals during grounding.
Make sure that the grounding device is electrically connected to the Module frame when
conducting grounding (e.g., if the frame is aluminum alloy, the insulated and anti-corrosion
anodic oxide coating on the aluminum alloy surface must be scrapped off for the grounding
device to allow contact with the internal aluminum alloy in order to provide grounding).
The grounding of the Module can be conducted through the recommended methods as
follows:
