General Principles Of Security
Modules rated for use in this application class may be used in systems
operating at greater than 50V DC or 240W, where general contact access is
anticipated. Modules qualified for safety through IEC 61730-1 and this part of
IEC 61730 within this application class are considered to meet the
requirements for safety class II.
No matter whether the PV module is connected to the system or not, proper
protective measures should be used when touching the PV module, such as
insulation tools, safety caps, insulation gloves, safety belts, and safety
insulation shoes. During installing, grounding, connecting cables, and
cleaning modules, the proper electrical protection tools must be used too.
Avoid contact with modules directly, which may cause electric shocks or cuts.
The installation should comply with the laws and regulations specified by the
relevant region and country. If necessary, obtain the required certificates
such as building permit.
Module installation shall be carried out by qualified professionals with
technical knowledge and familiarity with the mechanical and electrical
requirements of the system. Be aware of the risks of injury, including
electric shock, that may occur during installation.
The modules are applied to the ground, roof, fish pond and other outdoor
environments. Proper design of support structures is the responsibility of the
system designer or installer. When applied to roof installation, the overall
fire rating of the final structure needs to be considered, as well as the
overall maintenance of the later period. A roof system can only be installed
on a roof that has been assessed by a construction expert with the results of
a formal complete structural analysis.
Comply with safety regulations for all installed components. Such as wires and
cables, connectors, charging controllers, inverters, batteries, etc., only the
equipment, connectors, wires and brackets that match the solar power system
can be used. If the photovoltaic system uses energy storage batteries, the
configuration of the modules should follow the advice of the battery
manufacturer. Only same size modules and specifications can be connected in
series.
Meaning of crossed –out wheeled dustbin:Do not dispose of electrical
appliances as unsorted municipal waste, use separate collection facilities.
Contact your local government for information regarding the collection systems
available.
If electrical appliances are disposed of in landfills or dumps, hazardous
substances can leak into the groundwater and get into the food chain, damaging
your health and well-being.
When replacing old appliances with new ones, the retailer is legally obligated
to take back your old appliance for disposals at least free of charge.

Fire Safety
Before installing modules on the roof, refer to local laws and regulations and
comply with building fire protection requirements. The roof shall be covered
with a suitable grade of fireproof material for roof installation and to
ensure that the modules and mounting surfaces are fully ventilated. Different
roof structures and installation methods can affect the fire performance of a
building. Improper installation may cause a fire.
Use appropriate components such as fuses, circuit breakers and ground
connectors according to local regulations.
Do not install or use modules near open flames or flammable or explosive
objects.
Transportation safety
Do not open the packing case before the modules arrive at the installation
site. Place the packing case in a dry and ventilated environment.
During all handling, ensure that the module will not be shaken, dropped to the
ground, or objects will fall on the module, as this will damage the module or
the solar cells in the module. Do not allow children or unauthorized persons
to handle modules. Improper handling and placement may result in glass
breakage or loss of electrical properties, thus rendering the modules useless.
Handle and installation modules with care. Under no circumstances should
assemblies be lifted by lifting junction boxes or cables. Two or more persons
must hold the edges of assemblies with both hands.
Do not step on, stand on or sit on modules as this can damage modules and risk
injury to people.
Do not stack modules, do not place any heavy objects on the front and back of
modules, and do not place modules on sharp surfaces.
Install Security
Comply with safety rules applicable to all installed modules. Such as wires
and cables, connectors, charging controllers, inverters, batteries, etc., only
the equipment, connectors, wires and rails that match the solar power system
can be used.
If the photovoltaic system uses energy storage batteries, the configuration of
the modules should follow the advice of the battery manufacturer.
Do not install or operate s in damp or windy conditions, and keep the junction
box cover closed.
The glass can protect the module, improper operation may cause the glass to be
broken. Damaged module pose a risk of electric shock and fire. Such modules
cannot be repaired or repaired and should be replaced immediately.
When sunlight strikes the front of the module, the module generates
electricity and the DC voltage may exceed 30V. Avoid direct contact with the
voltage of 30V or higher to avoid danger.
To reduce or avoid the array mismatch effect, it is recommended to connect
modules with similar electrical properties on the same string.
When connecting modules, ensure that the connecting cables are fixed on the
support frame of the nodule to limit the swing of the slack part of the cable.
Comply with the minimum bending radius of the cable (not less than 43mm is
recommended).
Electrical Properties
Electrical installation
The module product specification lists the specific electrical performance of
photovoltaic modules in detail, and the nameplate of each module is also
marked with the main electrical performance parameters under STC conditions
(1000W/㎡, AM 1.5, cell temperature 25°C). The product specification and
nameplate are also marked with the maximum system voltage of the module.
Under certain environmental conditions, the current or voltage generated by
the module may be greater than the operating current or voltage for standard
test conditions (STC). Therefore, when determining the current/voltage ratings
and load values of electrical components, the module short-circuit current
under STC should be multiplied by 1.25, and the open-circuit voltage should be
corrected according to the calculation formula below:
Maximum System Voltage ≥ N×Voc×[1＋λvoc（Tmin-25℃）
While,
N — The maximum number of PV module connecting in parallel ( see Appendix A)
Voc — Open circuit voltage value of module under STC (see module nameplate)
λvoc — Open circuit voltage temperature coefficient of the module (see module
technical specification)
Tmin — Annual minimum temperature for module installation position (for
example, -20 ° C, Tmin = -20)
When determining the appropriate wire and fuse specifications, the maximum
fuse current rating is selected by reference to the product specifications.
The system electrical design and calculation shall be determined by a
qualified electrical engineer.
The minimum over-current protection device specification is determined by
calculating the maximum expected current of the photovoltaic system. The
maximum over-current protection device specification is mandatory in IEC
61215:2016 and IEC61730:2016 standards.
If there may be a reverse current through the module that exceeds the maximum
fuse current, the module must be protected by over-current protection. If the
number of parallel connections is greater than or equal to 2, an over-current
guard must be installed on each assembly.
Do not install in rainy weather, moisture will lead to insulation failure,
prone to safety accidents.
For specific electrical performance parameters, please refer to the product
specifications.
Cables and wires
The modules use junction boxes with protection class IP68 or above, with
connected cables and connectors.
The junction box of each module is equipped with two separate wires, one
positive and one negative, which can be connected in series by inserting the
positive connector of one module into the socket of the negative connector of
the adjacent module.
During installation, do not use lubricating oil or alkane cleaning agents to
clean connectors, junction boxes, and cables.
The cross-sectional area of the cable and the capacity of the connector must
meet the maximum short-circuit current of the module (for a single module, the
cross-sectional area of the cable is 4mm , and the cable temperature ranges
from -40 ° c to +90 ° c).
When the cable is fixed on the bracket, it is necessary to avoid mechanical
damage to the cable or module.
The cable is fixed on the bracket with specially designed light resistant tie
and cable card. The cable is light resistant and waterproof, and also avoid
direct sunlight and water soaking the cable.
Connector
When connecting modules, ensure that the connectors of the same string of
modules are from the same manufacturer or fully compatible, and the connection
terminals of the modules and the system must also be in he same way. The
connectors of different manufacturers may be incompatible, which may cause
mismatching and burning.
Keep the connector dry and clean.
Do not connect the connector when it is damp or dirty.
Do not expose the connector to direct sunlight or water.
Bypass Diode
The junction box of the tongwei module contains the bypass diode and forms a
parallel structure with the circuit. When the solar cells of the module is
blocked or damaged, the hot spot phenomenon occurs in the part of the module,
the diode will work, so that the current no longer flows through the hot spot
solar cell, so as to limit the heating and performance loss of the module.
Note that the bypass diode is not an over-current protector.
Grounding
The module use anodized corrosion-resistant aluminum alloy frames as rigid
supports. To protect the module from lightning and static electricity, and to
protect personal safety. All frames and mounting brackets of the components
must be grounded. If there are no specific regulations, please follow the
International Electrotechnical Commission standard or other international
standards. Connect the ground cable with the recommended connection terminal
and fix it to the module frame. It is recommended to use 12AWG copper core
wire. Figure 1 shows the grounding hole and its identification on the
assembly, and Figure 2 shows the assembly grounding method.
The holes are used for grounding only and cannot be used to install
module. Do not drill any additional ground holes on any frame of the modules.
Otherwise, the module warranty will be invalid.
When grounding, the grounding device must fully contact the interior of
aluminum alloy, penetrate the oxide film on the surface of the frame, and
connect the frame of the module and the supporting member to achieve good
grounding effect. Use an electroplated support frame to ensure good electrical
conductivity.
The ground conductor must be connected to the ground by a suitable ground
electrode. You are advised to use a ground cable accessory (wiring nose) to
connect the ground cable. Weld the ground cable into the socket of the wiring
nose, insert the M4 screw into the ring of the wiring nose and the hole in the
middle of the module frame, and secure the cable using a nut. Spring washers
should be used to prevent screw loosening resulting in poor grounding.
If the module is used in a high temperature and humidity environment, it is
recommended to install an inverter with an isolation transformer that can be
negatively grounded (figure 3 shows the system voltage polarity
configuration).
The module may be grounded using a
third party grounding device, provided that the grounding device is reliable
and proven and operated in accordance with the manufacturer’s requirements.
Handling, transportation, storage and unpacking
Tongwei’s module have horizontal packaging and vertical packaging according to
different product. There are significant differences between horizontal
packaging and vertical packaging in loading, unloading, transportation and
unpacking. Please be sure to follow the above operations in this manual.
The patterns of horizontal and vertical packing are as follows:
Handling, Transportation and Tran-shipmen hipped, Tongwei
uses wooden frames of the same size as the modules as packing fillers. The
wooden frames are located in the middle of the packaging body, and the
scattered packaging method is exactly the same as the integral packaging
method. t
After the module arrived, please check the overall status of the package in
time. If there is any abnormal condition such as package damage, deformation
or skew, please contact the customer service or logistics personnel of Tongwei
immediately.
Place the module on flat ground after transporting it to the installation
site.
Forklift to unload
If forklift tools are used, the forklift tools should be reasonably selected
according to the size and weight of the goods. If the fork of the forklift is
less than 3/4 of the size of the cargo, it should be covered with an extended
fork assembly to avoid tipping the package when moving the forklift.
Straight-line driving speed control of forklift truck transportation ≤5km/h,
turning speed ≤3km/h; During transportation, the spacing between goods and
inserts should be adjusted to the maximum position of the spacing between
pallets.
During loading and unloading, except forklift operators, other personnel
should keep within a safe distance to ensure personnel safety.
Lifting the unloading If a crane is used to unload the package, use a
dedicated hoisting tool. Select a proper hoisting tool based on the weight and
size of modules. Use a fixing tool of the same size on the top of the package
to prevent the lifting rope from squeezing the package or modules.
Horizontal packaging can lift up to 4 sets of modules at a time, vertical
packaging can lift up to 2 sets of modules at a time.
Tran-shipment If vertical packaging modules need to be transported to the
construction project site through secondary transportation after being
transported to the centralized storage site by container or flatbed vehicle,
the following points should be noted:
If forklift truck is used for transport, the forklift truck shall comply with
the above requirements for unloading, and the forklift truck size shall be at
least ≥ 3T; If you use a box truck or other type of vehicle, please use a
carriage with guardrail, the height of the guardrail is not less than 2/3 of
the height of the module, and use fastening straps to secure the module to the
carriage; modules should be placed closely with each other, and gaps should
not be left.
If the vertical package is turned to horizontal by a turning machine, please
note that the flat tray structure is used as the bearing unit of the module
after turning over, and only the frame surface of the module can be used as
the bearing surface of the module after turning over.

Module Installation
Installation environment
The module is recommended to be installed in an environment where the
operating temperature ranges from -20°C to 50°C. The maximum operating
temperature ranges from -40°C to 85°C, and the humidity is lower than 85%RH.
When installing solar modules on a roof, it is also necessary to leave a safe
working area between the edge of the roof and the outer edge of the
photovoltaic module array.
When modules are piled on the roof, the load of the roof should be rechecked,
and the construction organization plan in accordance with the requirements of
the code should be formulated.
If in the northern hemisphere, usually choose the light facing south
installation of the module. If you are in the southern hemisphere, you usually
choose the light-facing north mounting of the module.
when selecting module installation position, should choose can make full
sunlight position, to avoid the module surface forms part or all of the shade
(trees, buildings, clothing, tools, packing materials and other obstacles),
because these objects on the
module form the shadow, the shadow will cause loss of output power.
The module should be installed in a well-ventilated place to ensure adequate
air circulation on the back and side of the module to facilitate the timely
release of heat generated when the module is working.
When used in areas with high wind pressure and snow pressure, support fixed
structures should be designed in strict accordance with local design
specifications to ensure that the external load does not exceed the mechanical
strength limit that the modules can bear.
At a place 50m to 500m away from the sea, corrosion may occur at the part
where the frame of the module is connected to the support, or the part where
the grounding is connected. Stainless steel or aluminum materials must be used
to contact the photovoltaic module, and the installation part must be treated
with anti-corrosion.
Please consult the Tongwei technical support department for more information
on the use of modules in special climates, such as an altitude greater than
2000m, heavy snow, severe hail storm, hurricane, etc.
Inclination Choice
The inclination Angle of the photovoltaic module refers to the included Angle
between the photovoltaic module and the horizontal ground. Different projects
choose different installation inclination Angle according to local conditions.
Modules connected in series of the same array must be in the same direction
and Angle. Different installation directions and angles cause differences in
the total amount of solar radiation absorbed by modules, resulting in a loss
of output power, which reduces the operating efficiency of the system.
The maximum power is generated when the sunlight directly exposure to the
modules. Consider the power output of the module in winter when selecting the
best installation Angle.
In order to facilitate module cleaning and wash away dust on module surface
when it rains, for detailed installation Angle, please follow the advice given
by experienced PV module installers.
Machinery Installation
Ensure that the module installation strong enough, supporting system composed
of the phalanx system components must be able to withstand the mechanical load
pressure, appointed by it’s bracket installer must provide the guarantee,
mounting bracket needed and static mechanics analysis ability of the third
party testing institutions to test, need to adopt international standards or
national standards. The mounting bracket of the component must be made of
materials that are resistant to corrosion, rust and UV.
Modules must be securely mounted on system supports.
Do not drill additional mounting holes in the frame and glass. Otherwise, the
module warranty will be invalid.
The support structure of modules has thermal expansion and cold contraction
effect. To avoid affecting the performance and use of modules, it is
recommended that the minimum distance between the two module is 10mm. To
ensure good ventilation of modules and reduce load, it is recommended that the
installation distance between two modules is 30mm.
In areas with heavy snow in the winter, choose a high mounting bracket so that
the lowest point of the module is not covered by snow for a long time, and the
lowest point of the module is high enough to prevent the module from being
obscured by plants or
trees.
The support surface of the installation bracket must be flat, without
distortion or deformation, and there is no up and down dislocation between the
connected brackets.
The assembly installation method should not result in electro-chemical
corrosion between the aluminum frame and different metals.
Location Choice
Roof
When installing on a roof or building, ensure that they are securely secured
and will not be damaged or dropped by strong winds or snow. Provide a special
mounting bracket for roof installation if necessary. The building code used
for roof installation should be checked to ensure that the building and
structure to which the modules are installed have sufficient load-bearing and
airtight properties. The roof through which the fixed modules are installed
should be sealed to prevent rainwater leakage.
To facilitate operation, reduce water vapor condensation, and promote
ventilation and heat dissipation for modules, ensure that the modules are
parallel to the surface of the wall or roof of the building. The distance
between the modules and the surface of the wall or roof is at least 115mm. In
this way, the air circulation at the rear of the modules facilitates heat
dissipation and prevents cable damage. When stacking modules, ensure that the
modules are installed on A fireproof roof. The module has a fire rating of C
and is suitable for installation on a roof with fire rating of A or higher.
For the roof system with heavy snow or snow record in the installation area,
the customer shall support and reinforce the bottom module frame of the entire
system to ensure that the bottom module is protected from top-down snow push
and pressure damage and damage to the module caused by daytime snow melt and
icing.
Struts
When installing modules on struts, select struts and module mounting brackets
that can withstand the expected local wind. The struts must have a solid
foundation.
Ground
Select an appropriate installation height for ground installation to prevent
the lower part of the module from being covered by snow for a long time in
winter. Install the modules on a support of an appropriate height. Do not lay
the modules directly on the ground. In addition, ensure that the minimum part
of the module is not less than 900mm to avoid being obscured by plants or
trees, to avoid being damaged by blown sand or being obscured by soil splashed
by rain. Wiring Tongwei provides recommended connection modes for customers.
If the connection modes required by the installation personnel are different
from the recommended connection modes, please contact Tongwei commercial
personnel to evaluate the feasibility of connection modes.
Photovoltaic modules can be connected in series to increase the series
voltage, and connected in parallel to increase the series current. Please
select a reasonable connection mode according to the electrical parameters of
the inverter selected by the photovoltaic system and the maximum system
voltage of the modules.
When connecting cables, pay attention to the polarity of the positive and
negative terminals of modules.
For different types of components, Tongwei provides optional wire lengths to
match different system wiring methods.
The following table describes the recommended system cabling methods.

On the premise of not affecting the overall design scheme of the system, it is
recommended that the modules of the horizontal plate series (integrated wire
box and located near the long side) be installed vertically, and the modules
of the vertical plate series (split wire box and located near the short side)
be installed horizontally, to avoid unnecessary power generation loss caused
by ash accumulation at the bottom of the inclined installation.
Installation Guide
Modules must be installed according to the installation instructions to comply
with IEC requirements.
Connections between modules and support systems can be installed using
mounting holes in the frame, clamps If the installation method used is
different from the recommended installation method, please get approval from
Tongwei.
Otherwise, modules may be damaged and the warranty may be invalid.
In extreme weather conditions or user-defined installation methods, strengthen
key connections to prevent damage to modules or system connections.
The loads described in this manual are test loads. According to IEC
installation requirements, a factor of 1.5 should be considered when
calculating the corresponding maximum design load. The design load of the
project depends on the project location, local climate, support structure and
related specifications. Support suppliers and professional engineers are
responsible for determining the design load. For more detailed information,
follow local laws and regulations as well as instructions from structural
engineers.
Installation method: Clamps
Use a certain number of clamps to secure the modules to the mounting rail.
Tongwei recommends that fixtures be clamped to the frame of module.
The clamps shall be made of anodized aluminum alloy or stainless steel.
The length and thickness of the clamp recommended by Tongwei are ≥50mm and 3mm
respectively.
The contact width between the clamps and the a side of the frame is in the
range of 7 ~ 11 mm.
Install and tighten on the mounting rails with the torque specified by the
mounting components manufacturer. The clamps is installed with m 8 × 1.25
bolts and nuts. For M8 heavy thread bolts, the tightening torque should be
between 16 Nm and 20 Nm depending on the bolt grade.
When installing the clamps, do not touch the front glass, and do not scratch
or deform the aluminum frame during the installation process. At the same
time, the clamps can not affect the operation of the module，and make sure that
the drainage hole and the grounding hole are not blocked.
Each module requires at least four clamps to be secured, and at least two
clamps for each long or short frame, depending on local application conditions
(wind and snow conditions) , an additional number of clamps may be required to
ensure that the modules and systems bear the corresponding loads, as shown in
Figures 7.
Clamps position is critical to the reliability of installation，center line
must be installed as described in the following table according to structural
and load requirements.
Four clamps mounting on long side of frame and rails perpendicularly to the

Maintenance
Modules need to be inspected and maintained regularly, especially during the
warranty period. To ensure optimum performance of the modules, the following
maintenance measures are recommended.
Cleaning
When modules are working, there should not be environmental influence factors
to cover shadows in the modules, such as other modules, supporting rail,
plants, large number of dust etc., which may directly reduce the power output
and may even cause regional hot–spot effect. Therefore clean the glass surface
on a regular basis, clean modules take measures so as:
The frequency of module cleaning depends on the speed of accumulation of dirt,
the rain will be carried out on the module surface is clean under normal
circumstances, , but still need to use a soft sponge or cloth (either dry or
touch water) clean the module, surface rough materials shall not be used for
any case clean, and acid and alkali cleaner to remove dirt is blocked too.
Avoid local heavy weight to the module during cleaning, which will lead to
module glass deformation, damage the solar cells, lead to reduce the service
life of modules.
Clear snow on modules in a timely manner to avoid damage to modules caused by
long-term snow accumulation and snow melting and freezing.
Do not pierce the back-sheet when cleaning the back of the module.
It is recommended to clean the modules in the early morning or evening when
the light is not strong and the module temperature is low, especially in areas
with high temperatures.
Do not attempt to clean modules with features such as broken glass or the
presence of exposed wires, which may be subject to electrical shock.
Visual inspection
Please carefully check the modules of the existence of visual defects,
focusing on the following items:
Check whether the module glass is broken.
Check if the front of the module is obstructed by obstacles or foreign
objects.
Check the module negative-sheet whether there is hot, negative film raised,
burn through the traces and so on.
Check whether the cell bus–bar is corroded, whether encapsulation materials of
the module has delamination, bubbles, etc.
Check the tightness of the bolts and the electrical connections at the
connection points between the modules and the supporting rail.
Inspection of connector and cable
It is advisable to carry out a preventive check every 6 months and check the
following:
Check Junction box adhesive for cracks or cracks.
Check the connector interface sealing and whether there is loose, melt
deformation, aging or corrode.
Check that the cable connections are secure and that the modules are properly
grounded.
When module is found to be defective, consult a qualified service technician.
If servicing is required, it should be serviced by aqualified service
technician.
Module exposure generates high voltages in the sun, so cover the modules with
opaque material when servicing modules to prevent electrical shock.
Note:
- If found in the maintenance of any problems, feedback to the professional service personnel for confirmation;
- If using maintenance and repair measures not included in this manual, consult your local dealer for professional support.
