Photovoltaic modules can produce current and voltage
if exposed to light of any intensity. The electric current
increases as the light intensity increases. DC voltage of 30V
or higher is potentially lethal. Connecting live circuits of a
photovoltaic system that operates under light can cause a
fatal electric shock.
Disconnect the photovoltaic modules by removing them completely from the

5User manual
English
light or by covering their surface with an opaque material. Observe the safety
regulations for live electrical equipment when working with modules that
are exposed to light. Use insulated tools and do not wear metal jewelry while
working with photovoltaic modules.
To avoid electric arc and electric shocks, do not disconnect the electrical
connections under load. Wrong connections can also cause arcs and electric
shocks. Keep the connectors dry and clean and make sure they are in good
working order. Never insert metal objects into connectors and do not modify
them under any circumstances to ensure an electrical connection.
Do not touch or handle photovoltaic modules that have broken glass, a broken
frame or damaged back film unless the photovoltaic modules have been
disconnected first and wear appropriate protective equipment. Avoid handling
photovoltaic modules when they are wet, unless you clean them first according
to the instructions in this manual. Never touch electrical connections that are
damp without protecting yourself with insulated gloves.
Transport and handling of solar panels
• The photovoltaic modules must be transported only in the original
packaging and kept in the packaging until they are ready for installation.
• Protect pallets against movement and damage during transport.
• Secure the pallets against falling.
• Do not exceed the maximum height of the pallets to be stacked, as
indicated on the pallet packaging.
• Store the pallets in a cool, dry place until the photovoltaic modules are
ready to be unpacked.
• Photovoltaic modules are heavy and must be handled with care.
• Photovoltaic modules must be handled by the frame; never use the junction
box or cables to handle the panels.
• Do not apply mechanical stress to the panel cables.
• Never step on photovoltaic modules and do not drop or place heavy objects
on them.
• Be careful when placing photovoltaic modules on hard surfaces and secure
them against falling. Broken glass can lead to personal injury. Broken glass
photovoltaic modules cannot be repaired and must not be used. Broken or
damaged photovoltaic modules must be handled with care and disposed of

User manual 6
English
in accordance with local regulations.
• To unpack the photovoltaic modules from the original packaging, first
remove the box cover (after removing the fastening straps, if provided).
Remove the photovoltaic modules one by one by sliding them up the
channel in the package (see figure below). It may be necessary to fix the
remaining photovoltaic modules in the pallet packaging to prevent them
from falling.
The surfaces of photovoltaic modules are likely to suer damage that could
aect the performance or safety of the photovoltaic module. Do not damage
or scratch the surface of the PV module and do not apply paint or adhesive to
any of the surfaces, including the frame.
For your safety, do not disassemble or modify the photovoltaic modules in any
way. This may aect performance or cause irreparable damage and will void
any applicable warranty.
If photovoltaic modules need to be stored before installation, photovoltaic
modules must remain inside the package and be protected from exposure to

English
sunlight or moisture that could compromise the durability of the package.
Fire protection
• PNI solar photovoltaic modules have fire resistance class C.
• When photovoltaic modules are mounted on roofs, the roof must have a
fire-resistant coating suitable for this application.
• Photovoltaic modules are devices that generate electricity that can aect
the fire safety of a building. The use of improper installation methods or
defective parts can lead to the unexpected appearance of an electric arc
during operation.
• To reduce the risk of fire, photovoltaic modules must not be installed near
liquids, flammable gases or places with hazardous materials.
• In the event of a fire, photovoltaic modules may continue to produce a
dangerous voltage, even if they have been disconnected from the inverter,
have been partially or completely destroyed, or the system wiring has been
compromised or destroyed.
• In case of fire, inform the fire crew and stay away from all elements of the
photovoltaic system during and after the fire until the necessary measures
have been taken to ensure the safety of the photovoltaic system.
Mounting restrictions
PNIphotovoltaicmodulesmustbemountedonmountingstructurespositioned
on buildings, ground or other structures suitable for photovoltaic modules.
Photovoltaic modules must not be mounted on moving vehicles.
Photovoltaic modules should not be installed in places where they could be
submerged in water.
Photovoltaic modules should not be placed in places where aggressive
substances, such as salt (or salt water) or any other type of corrosive agent,
could aect the safety or performance of photovoltaic modules.
Artificial concentrated light should not be directed at photovoltaic modules.
We recommend that the photovoltaic modules be mounted at an angle of
inclination of at least 10 degrees to allow self-cleaning under rain showers.

English
Partial or complete shading of a module can significantly reduce system
performance. We recommend minimizing the amount of shade throughout
the year to increase the amount of energy produced by photovoltaic modules.
Lightning protection is recommended for photovoltaic systems to be installed
in locations with a high probability of lightning. High system voltages can be
induced in the event of indirect lightning, which could damage the components
of the photovoltaic system.
The open area of the wiring loops must be kept to a minimum, as shown in the
figure below, to reduce the risk of lightning-induced overvoltages.

A - ideal wiring loop
B - higher risk of lightning-induced overvoltage
Electrical configuration
Under normal conditions, a photovoltaic module may face conditions that
produce more current or voltage than that reported under standard test
conditions (STC: 1000 W / m2, AM 1.5 and 25 ° C cell temperature). The
short-circuit current (ISC) must be multiplied by a factor of 1.25, and the
open-circuit voltage (VOC) must be multiplied by a factor of up to 1.25, based
on the lowest ambient temperature recorded at the installation location to
determine the nominal voltage of the components. , the rated current of the
conductor, the dimensions of the fuses and the size of the controls connected

to the PV output.
Voltage accumulates when photovoltaic modules are connected in series, and
current accumulates when photovoltaic modules are connected in parallel, as
shown in the figure below.
Photovoltaic modules with dierent electrical characteristics must not be
connected in series. Third-party electronic devices connected to photovoltaic
modules must be installed according to the instructions specified by the
manufacturer

B
A - Series connection (voltage accumulates)
B - Parallel connection (current accumulates)
The maximum number of photovoltaic modules that can be connected in a
series series must be calculated in accordance with the applicable regulations,
so that the declared maximum voltage of the photovoltaic module and all other
direct current electrical components is not exceeded in open circuit operation
at the lowest temperature expected at the location of the photovoltaic system.

User manual 10
English
An overcurrent protection device must be used when the reverse current
could exceed the nominal value of the maximum safety of the module. An
overcurrent protection device and an anti-reflection diode module are required
for each series series if more than two series are connected in parallel, and the
reverse polarity is prohibited.
Wiring
PNI photovoltaic modules are equipped with two output cables, resistant to
sunlight, equipped with connectors at the ends.
The positive (+) terminal has a mother connector, while the negative (-) terminal
has a male connector. The module wiring is intended for serial connections, but
can also be used to connect third-party electrical devices, which may have
alternative wiring configurations, as long as the manufacturer’s instructions are
followed.
Use cables with a suitable cross section that supports the maximum short-
circuit current of the photovoltaic module. PNI recommends that installers use
only sunlight-resistant cables dedicated to photovoltaic systems. The minimum
thread size must be 4 mm2. Cable temperature range: -40 ° C ~ + 90 ° C.
The cables must be fixed to the mounting structure so as to avoid mechanical
damage to the cable or module. Do not bend the cables to a bending radius
of less than 40 mm. For fixing, use suitable means, such as sunlight-resistant
collars and cable clamps specially designed to be attached to the photovoltaic
module.
Connectors
• Keep connectors dry and clean. Do not attempt to make an electrical
connection with wet, dirty or defective connectors. Avoid sun exposure
and watering the connectors.
• Make sure you tighten the connector covers securely before connecting
the modules.
• Faulty connections can cause arcs and electric shocks. Check that all
electrical connections are properly made.
• Make sure all connectors are fully connected and locked. The modules must
not be interconnected using connectors from dierent manufacturers or

of dierent types.
+–
Bypass diode
The junction boxes used with the photovoltaic modules contain bypass diodes
connected in parallel with the rows of photovoltaic cells.
In the case of partial shading, the diodes divert the current generated by
the unshaded cells, thus limiting the heating of the module and the loss of
performance.
Bypass diodes are not overcurrent protection devices. Bypass diodes divert
current from cell strings in the event of partial shading.
See thefigurebelowthatshowshowthecellstringsareconnectedtothediodes.

User manual 12
English
In case of a diode failure, the installers or maintenance operators must contact
the company from which the photovoltaic modules were purchased. Never try
to open the junction box of a photovoltaic module yourself.
Grounding of the PV Array
For optimal performance, PNI recommends that the negative pole of the
photovoltaic matrix be connected to ground.

13 User manual
English
Earthing the equipment
The frame of the photovoltaic module, as well as any exposed, non-current
metal parts of the fixed equipment that can be powered by the photovoltaic
system, must be connected to the equipment grounding conductor (EGC) to
prevent electric shock.
PNI recommends grounding all frames of photovoltaic modules to ensure that
the voltage between the conductive electrical equipment and grounding is zero
in all circumstances.
Adequate grounding of the equipment is achieved by connecting all metal
equipment that does not carry current, using an EGC (equipment grounding
conductor) of adequate dimensions to prevent electric shocks.
PNI photovoltaic modules have an aluminum frame with corrosion resistance.
The corrosion potential due to the electrochemical action between dierent
metals in contact is minimized if the electrochemical voltage potential between
the dierent metals is low.
The grounding method must not result in direct contact of the metals with
the aluminum frame of the photovoltaic module, which will lead to galvanic
corrosion.
Metal combinations must not exceed an electrochemical potential dierence
of 0.5 V. The frame rails have pre-drilled holes marked with a ground mark, as
shown in the figure below. These holes must be used for earthing and must not
be used for mounting photovoltaic modules. Do not make additional holes in
the frame.

English
ø0.236in (6mm)
The following earthing methods are available:
Option A: Screw assembly (see figure below)
1. A grounding screw assembly must be attached to a grounding hole, using
only stainless steel hardware. First insert an M5 stainless steel screw through
the washer and then through the earthing hole.
2. Lightly tighten the stainless steel nut and locking washer on the screw.
3. Bend the EGC (ground conductor) into an omega (Ω) shape to fit between
the partially installed screw head and the washer. EGC must be in exclusive
contact with stainless steel.
4. Tighten the screw to a torque of 2.3 N ∙ m. The toothed locking washer
should be visibly coupled to the frame.
5. Route the EGC to the appropriate size to avoid contact with the aluminum
frame of the module.
