•When operating photovoltaic modules in the
sun, please use insulated tools, and wear
rubber gloves and protective clothing. At the
same time, in order to avoid the risk of arc and
electric shock, do not directly touch the junction
box and the end of the output cable (connector)
with your hands.
•When the photovoltaic modules are electrically
connected choose a dry and low sunlight period,
preferrably morning or evening; or use opaque
materials to completely cover the surface of the
photovoltaic modules to prevent current
generation.
•A certain distance between the photovoltaic
module and the installation surface should be
kept to prevent the installation surface from
touching the junction box.
•When installing on the roof, comply with the fire
protection requirements of the building. It is
recommended to install photovoltaic modules
on a fireproof and insulated roof covering, and
ensure adequate ventilation between the
photovoltaic modules and the installation
surface. In order to ensure the fire rating on the
roof, the minimum distance between the frame
of the photovoltaic module and the roof surface
is 10 cm.
•The connector must be fully mated when wiring.
If the cable is too long, it is recommended to fix
the cable to the installation system with a UV
resistant nylon cable tie. When fixing the cable
to the bracket, the bending radius of the cable
should not be less than 48mm.
•Avoid directly exposing cables and connectors
to sunlight. Please use anti-ultraviolet cables.
•Do not disconnect the electrical connection
when there is a load.
•It is strictly forbidden to try to disassemble the

follow the cleaning requirements of photovoltaic
modules.
•The connectors must be kept dry and clean to
ensure that they are in good working condition.
Do not insert other metal objects into the
connector or make electrical connections in any
other way.
5 Handling and unpacking
If the photovoltaic module is not in use, please do
not open the product packaging. The goods should
be stored in a dark, dry and ventilated place. If the
photovoltaic modules are stored in an uncontrollable
environment, the storage time must be less than 3
months when the outer packaging of the photovoltaic
modules is kept intact.
It is recommended to take appropriate amount of
photovoltaic modules for unpacking according to the
project progress every day, and the unpacked
photovoltaic modules should be installed within a
day. After unpacking, the photovoltaic modules are
stacked on the ground. In severe weather such as
heavy rain, the photovoltaic modules may be
immersed in water for a long time and affect the
reliability of the product. In severe weather such as
typhoons, photovoltaic modules that have not been
installed may also be scraped away.
5.1 Transport
When the photovoltaic modules are transported to
the project site, they must be transported in the
packaging box provided by 8 Star Energy, and
should be stored in the original packaging box before
installation. Please protect the packaging from
damage.
It is necessary to protect the safety of photovoltaic
modules when unloading, especially when hoisting
roof projects. It is forbidden to use lifting straps
directly on the pallet for hoisting. The photovoltaic
modules should be placed in a protective device and
then hoisted to the roof to prevent the packing box
from deforming and bumping against any walls
during the hoisting process.
There are two packaging methods for 210mm-wafer
modules, vertical portrait package and vertical
landscape package. The requirements for unloading
and unpacking are also different. The packaging
method is as follows:
Vertical portrait package Vertical landscape package

Distance between the upper surface of the forklift
tines and the ground.
5.2 Unpacking
Before unpacking, please make sure that the
packaging box is in good condition, it is
recommended to use an art knife to remove the
packing belt and wrapping film. When unpacking,
you need to remove the stretch film first, then use a
knife to cut the binding tape, and remove the packing
box cover.
It is strictly prohibited to unload modules under
the weather conditions of wind speed greater than
Level 6, heavy rain or heavy snow.
If the inner packaging is fixed with anti-falling tape, a
group of two should hold the frame with both hands
in the same direction and take out the photovoltaic
modules one piece at a time, and remove the
photovoltaic module by tearing off a piece of fixing
glue. The photovoltaic modules in the box will fall; if
the internal packaging is fixed by the internal packing
belt, first cut the internal packing belt, use
anti-inverted sticks and other non-sharp and reliable

8 Star Energy Pty Ltd | Level 35, 477 Collins Street, Melbourne VIC 3000 | https://www.energizersolar.com
8 Star Energy ESS Ltd | The Black Church, St Mary’s Place, Dublin DO7 P4AX, Ireland
items to hold one side of the long side frame, and
then cut the other side. Two people can then move
and take out the photovoltaic modules one by one
around the frame; the whole handling process needs
to be handled with care, and you must make sure to
not collide with any hard objects or allow any part of
the frame to touch the ground or be dragged.
If the unpacked modules are not
installed immediately, they should be
fixed to the stand supporter with a
safety rope.When the modules need to be
temporarily stored after unpacking, they should
be neatly and stably stacked on two pallets of
appropriate size, the number of stackedmodules
should not exceed 14.
1. Prepare the following tools before unpacking:
art knife (scissors), safety hat, stand supporter,
safety shoes and anti-cutting gloves.
2. Stand supporter must be used for vertical
portrait package unpacking, and the steps are
as follows:
3. Remove the packing belts, wrapping film, top
cover and carton box.
4. Place the stand supporter into the bottom of the

17. Take out the modules in order.
Vertical landscape package unpacking steps
5.3 Stacking of photovoltaic modules
When taking out the photovoltaic module from the
packing box, you need to lay the cardboard on the
ground first to prevent the photovoltaic module from
colliding and scratching with any cement surface or
hard object such as the ground, color steel, tiles,
metal corrugated roofing, etc.
When the photovoltaic modules are stacked, they
must be neatly and stably stacked on a horizontal
surface, and stacked with the glass side facing down
and the back side facing up. At the same time, there

10
8 Star Energy Pty Ltd | Level 35, 477 Collins Street, Melbourne VIC 3000 | https://www.energizersolar.com
8 Star Energy ESS Ltd | The Black Church, St Mary’s Place, Dublin DO7 P4AX, Ireland
must be cardboard bedding under the photovoltaic
modules. For example, when installing photovoltaic
modules on the roof, the number of modules stacked
up on a pile should not exceed 20. For roofs with
poor load-bearing capacity, it is recommended that
the designer or installer evaluate the load-bearing
capacity of the roof and reduce the load-bearing unit
area of the roof by reducing the number of piles. At
the same time, avoid placing any installation tools or
other objects on the surface of the photovoltaic
module.
Energizer Solar PV modules adopt high and low
current bins, and the handlers need to place them
separately and mark them according to the markings
on the power list of the PV modules outer packaging
(for example, 270W-L means low current gear;
270W-H means high current gear position; the
current division method required by other customers
is similar). According to the system design
requirements, the same current gear position is
usually required in the same array during installation.
If the customer requires PV modules to be
distinguished by color, the outer packaging box shall
be marked accordingly, and the PV modules shall be
marked to prevent confusion when they are taken
out of the packaging box and stacked. According to
the system design requirements, the color of
photovoltaic modules in the same row or square
array should be the same.
6 Mechanical installation
6.1 Installation conditions
•Recommended ambient temperature: -20°C to
+50°C;
•Extreme working environment temperature of
photovoltaic modules: -40°C to +85°C.
•Photovoltaic modules mechanical load: Under
standard installation conditions, the maximum
test snow/wind load is 5400Pa/2400Pa, and the
design load (considering a safety factor of 1.5)
is 3600Pa/1600Pa.
For specific installation methods and mechanical
load values of photovoltaic modules, please refer to
Table 2 for detailed installation instructions for
photovoltaic modules.
Photovoltaic modules are strictly prohibited to be
installed and used in excessive environments such
as hail, snow, hurricane, sandstorm, dust, air
pollution, and soot. It is strictly forbidden to install or
use photovoltaic modules in an environment with
strong corrosive substances (such as salt, salt spray,
salt water, active chemical vapor, acid rain, strong
steam, or any other substances that will corrode
photovoltaic modules and affect the safety or
performance of photovoltaic modules).
If photovoltaic modules will be installed in special
environments such as high temperature and high
humidity environment, wet salt fog environment (C3
and above areas specified in ISO 9223), water and
breeding farms, etc., the purchaser or user must
inform 8 Star Energy in advance. The types of
photovoltaic modules, BOM, and quality assurance
issues shall be decided by the two parties through a
joint agreement and understanding.
If the above precautions are not followed, the
warranty will be invalid.
6.2 Installation angle selection
•The tilt angle of the modules is measured
between the surface of modules and a
horizontal grounding face, as shown in figure 1.
The modules generate maximum power output
when it faces the sun directly.
•In the northern hemisphere, modules should
typically face south, and in the southern
hemisphere, modules should typically face
north. Dust building up on the surface of the
modules can impair module performance, 8
Star Energy recommends installing the modules
with a tilt angle of at least 10 degrees, making it
easier for dust to be washed off by rain. At the
same time, it is conducive to the flow of
accumulated water on the surface of the

11
8 Star Energy Pty Ltd | Level 35, 477 Collins Street, Melbourne VIC 3000 | https://www.energizersolar.com
8 Star Energy ESS Ltd | The Black Church, St Mary’s Place, Dublin DO7 P4AX, Ireland
module, and avoids long-term large amounts of
accumulated water leaving marks on the glass
surface, thereby affecting the appearance and
performance of the module.
Figure 1: Schematic diagram of tilt
angle
•PV modules connected in series should be
installed in the same orientation and angle. If
the orientation and angle are different, the solar
radiation received by each module may be
different, resulting in power loss.
6.3 Installation Method
•The photovoltaic module mounting bracket
must be made of durable, corrosion-resistant,
and UV-resistant materials. The mounting
bracket must be inspected and tested by a
third-party testing organization with static
mechanical analysis capabilities to meet the
country, region, or corresponding international
standards.
•The photovoltaic module must be firmly fixed on
the mounting bracket. If the photovoltaic
module is installed in a snow-covered area, the
height of the support should ensure that the
lowest point of the photovoltaic module will not
be covered by snow. In addition, it should be
ensured that the lowest point of the photovoltaic
module will not be blocked by surrounding trees
or other plants.
•When the photovoltaic module is installed on a
bracket parallel to the roof, the minimum gap
between the frame of the photovoltaic module
and the roof is 10cm, and air circulation is
required to prevent damage to the wiring of the
photovoltaic module.
•The frame of the photovoltaic module will have
the effect of thermal expansion and contraction,
and the spacing between the two adjacent
photovoltaic module frames should not be less
than 10mm during installation.
For specific installation methods, please refer to the
following installation specifications.
6.4 Bolting through the mounting holes
All modules must be securely fastened with at least
4 bolts (As shown in Figure 2, 3, 4, 5, 6, 7, 8, 9).

x M6 stainless steel bolts are required (Figure
5).
③Secure each bolt to the frame with
stainless-steel washers, one for each side of the
mounting structure; and screw on either a
stainless-steel spring washer or a toothed lock
washer. Finally, secure with a stainless steel nut.
④The reference value of tightening torques should
be within 9~12Nm & 17~23 Nm respectively for
M6 & M8 bolts, depending on bolt class. For the
bolt grade, the technical guideline from the
fastener suppliers should be followed. For the
torque value, recommendations from specific
clamping hardware suppliers should prevail.
6.5 Clamping on the frame surface
Photovoltaic modules can be installed across the
support frame (Figure 11) or parallel to the frame of
the photovoltaic module (Figure 12). When using
clamps to install, each photovoltaic module must be
fixed with at least 4 clamps.
Figure 11: Rail vertical long frame
installation
Figure 12: Rails overlapping for the
short-side of frame
Figure 13: Four clamp mounting on short
side of frame.
The length of supporting bars must be
longer than the length of module frame,
otherwise please confirm with our
product team to get approval.
•The above three diagrams show the installation
method using aluminum clamps (also called
fixtures). "D" indicates the allowable installation
range of the aluminum press block. Please refer
to Table 2 for the specific recommended
installation location and corresponding load
("---" indicates that the photovoltaic module
does not apply to the above installation
methods).
•Each aluminum pressure block is equipped with
an M8 bolt, a flat washer, a spring washer and
an M8 nut. The fixing steps are as follows:
①Place the module on the two supporting bars (not
provided). The bars should be made with
stainless material and treated with an
anti-corrosion process (e.g., hot dipped
galvanizing). Each PV module needs at least four
clamps to fix. Do not make the clamp have
contact with the glass directly and do not make
the aluminum frame distort as part of the
installation process. Avoid shadowing of the solar
PV modules, otherwise this may affect the
modules operation or performance.
②Be sure to avoid shadowing effects from the
module clamps. Weep holes on the module frame
must not be closed or obscured by the clamps.

The clamp must overlap the module frame by at
least 8mm but no more than 11mm (The clamp
section can be changed under the premise of
ensuring the reliable installation of the
components).
③The bar’s top surface contacted with module
frame should come with grooves compatible with
an M8 bolt.
④If the bars do not come with grooves, holes of a
suitable diameter may need to be drilled to allow
bolts to be attached to the bars at the same
locations as mentioned above.
⑤Secure each clamp by attaching plain washer,
spring washer, and nut, in that order.
⑥Both close-ups in Figure 10, indicating the middle
clamps and Figure 9, indicating the side clamps
are for reference. Suggested dimensions for
middle clamps are: a ≥40 mm, b ≥26 mm, c≥
5 mm, d ≥28 mm, and Ø = 9 mm. The torque for
tightening the nut and bolts are recommended
17~23Nm when the property class of bolts and
screws is Class 8.8.

intermediate pressing block
⑦For the installation method shown in Figure 8, the
modules need to be fixed with professional solar
pressure blocks (as shown in Figure 11), and the
overlap between the C surface of the module and
the guide rail should be ≥15mm. If improper
fixtures or incorrect installation methods are used,
the limited warranty will be invalid.

7 Electrical Installation
7.1 Installation Conditions
Module electrical ratings are measured under
Standard Test Conditions (STC: 1000W/m2
irradiance, AM1.5 spectrum and a cell temperature
of 25°C). Please refer to the datasheet or the
product nameplate for the main electrical
characteristics, maximum system voltage and
tolerance of Isc, Voc and Pmpp.
Under certain conditions, the output current
and/or voltage of the PV module may be higher
than the value under standard testing conditions.
Therefore, the value of Isc marked on the module
should be multiplied by 1.25, and Voc on the
module should be multiplied by a correction factor
(see table 3 below) when determining component

16
8 Star Energy Pty Ltd | Level 35, 477 Collins Street, Melbourne VIC 3000 | https://www.energizersolar.com

ratings and capacities. Depending on your local
regulations, an additional 1.25 multiplier forthe
Isc(giving a total multiplier of 1.56) may be
applicable when sizing conductors and fuses.
Table 3 Correction factor of Voc at low temperature

-21 ~-25 1.20
-26 ~-30 1.21
-31 ~-35 1.23
-36 ~-40 1.25
Alternatively, a more accurate correction factor for
the Voc can be calculated using the following
formula:
C voc=1-αVoc x（25-Tmin）
Where: C voc is the correction factor of Voc.αVoc
(%/°C) is the open-circuit voltage temperature
coefficient of the selected module (refer to
corresponding datasheet).Tmin(°C) is the expected
lowest ambient temperature at the system
installation site.
The string voltage must not be higher than the
maximum system voltage, as well as the maximum
input voltage of the inverter and other electrical
equipment installed in the system. To ensure the
above requirements, the open-circuit voltage of
the string needsto be calculated using the
following formula:
Maximum system voltage≥N*
V oc*Cvoc
Where: N is the number of PV modules in a single
string. Vocis the open-circuit voltage of each PV
module (refer to the nameplate or product
datasheet).
Depending on the maximum fuse
ratings of the PV module, and the
local electrical installation
standards, the connection of
parallel strings of PV modules needs to be
equipped with suitable fuses or preventive diodes
for circuit protection purposes. Electrical
calculations and design must be performed by a
competent engineer or consultant.
The IEC & UL standard maximum system voltage for
the regular module series is 1500V according to the
requirements. The IEC & UL standard maximum
system voltage for half-cell module series is 1500V.
The maximum voltage of the system must be less
than the maximum certified voltage and the
maximum input voltage of the inverter and of the
other electrical devices installed in the system.
To calculate the maximum number of connections of
a series of PV modules, the following formula can be
used:
N = 1500V / (VOC * (1+(Tmin-25℃) * x%)
which shall consider the lowest on-site temperature.
In the formula，1500V is the system voltage, VOC is

8 Star Energy ESS Ltd | The Black Church, St Mary’s Place, Dublin DO7 P4AX, Ireland
the corresponding open-circuit voltage of the module
under STC condition, and Tmin(°C) is the lowest
on-site temperature. 25 ℃is the standard cell
temperature, and x% is the temperature coefficient
corresponding to the open-circuit voltage from the
panel spec sheet.
When the modules connect in parallel, the output
current will be equal to the sum of each branch
current. We suggest that every series SPV module
string should be fused prior to be connected with
other strings. The maximum number of modules:
N = Imax (maximum fuse current)/Isc.
Please refer to the applicable regional and local
codes for additional fuse requirements.
Under normal conditions, a photovoltaic
module is likely to experience conditions
that produce more current and/or voltage
than reported at standard test conditions.
Accordingly, the value of Isc marked on this
module should be multiplied by a factor of 1.25
when determining component conductor
ampacities, fuse sizes, and size of controls
connected to the PV output.
•Refer to Section 690-8 of the National Electrical
Code for an additional multiplying factor of
125% (80% derating）which may be applicable.
That means, when determining the voltage
rating, conductor capacity, fuse rating, and
photovoltaic output control size, the parameters
need to be multiplied by the square of 1.25.
•According to the max fusing rate of modules
and local electical installation standard, the
parallel connection of PV module arrays should
use the proper fuse to protect the circuit.
7.2 Installation conditions
In order to ensure the normal operation of the
system, when connecting photovoltaic modules or
connecting loads (such as inverters, batteries, etc.),
observe to ensure that the polarity of the cable is
connected correctly. If the PV module is not
connected correctly, the bypass diode may be
damaged. Figure 12 shows the connection of
photovoltaic modules in series and parallel. PV
photovoltaic modules can be wired in series to
increase the voltage. The series connection is to
connect the wiring from the positive terminal of one
photovoltaic module to the negative terminal of the
next photovoltaic module. PV photovoltaic modules
can be connected in parallel to increase current.
Parallel connection is to connect the wiring from the
positive terminal of one photovoltaic module to the
positive terminal of the next photovoltaic module. If
the PV module is not connected correctly, the
bypass diode may be damaged.

•If one set of arrays is connected to
another with the opposite polarity,
it will cause irreparable damage to
the product. Before connecting in parallel, be
sure to confirm the voltage and polarity of each
column. If the measurement finds that the polarity
between the columns is reversed or the voltage
difference is greater than 10V, you must check
the structure and configuration before making the
connection.
•The number of photovoltaic modules in series
and parallel must be designed reasonably
according to the system configuration.
•Photovoltaic modules of different electrical
performance models cannot be connected in a
string.
•Special solar cables and connectors should be
used in the system, and all connections should
be securely tightened. The cable size should be
4mm2 (12 AWG) and must be able to withstand
the maximum open circuit voltage of the
photovoltaic system.
•When the cable is fixed on the bracket, it is
necessary to avoid mechanical damage to the
cable or photovoltaic module, and do not press
the cable with force. To fix the cable through the
proper way, a specially designed tying coil and
wire clip must be used to fix it on the bracket.
Avoid direct sunlight and water soaking cables.
•Please keep the connector dry and clean, and
make sure that the nut of the connector is
tightened before connecting. Do not connect the
connector when it is found that the connector is
wet, dirty, or in other bad conditions. Avoid direct
sunlight and immersion of the connector in water.
Avoid the connector falling on the ground or roof.
•When the photovoltaic module is in a live state,
please do not plug or unplug the connector.
When it is necessary to open the connector,
ensure that the photovoltaic module is in a
non-working state, and must use professional
unlocking tools and safety protection measures. It
is forbidden to pull or damage the locking
structure.
•The junction box of the photovoltaic module
contains bypass diodes connected in parallel to
the battery string of the photovoltaic module. The
bypass diode in the junction box can avoid the
degradation of photovoltaic module performance
caused by shading or covering. Please refer to
the junction box diode specifications provided in
the relevant product specifications.
•When a local hot spot phenomenon occurs due to
partial shading or covering of the photovoltaic
module, the diode in the junction box will start to
work, so that the photovoltaic module current will
no longer flow through the hot spot cell, thereby
limiting the heating and performance loss of the
photovoltaic module. When you suspect or find
that the diode is malfunctioning, please contact 8
Star Energy, please do not try to open the
junction box cover by yourself.
7.3 Grounding
Energizer Solar modules use an anodic oxidized
aluminum frame to resist corrosion. So the frame of
modules should be connected to the equipment
grounding conductor to prevent electrical shock. The
grounding device should fully make contact with the
inside of the aluminum alloy, and penetrate the
surface of the frame oxidation film.
The following is the specific grounding method, as
shown in Figure 13.

8 Star Energy Pty Ltd | Level 35, 477 Collins Street, Melbourne VIC 3000 | https://www.energizersolar.com
8 Star Energy ESS Ltd | The Black Church, St Mary’s Place, Dublin DO7 P4AX, Ireland
Figure 18 Use copper cables to ground
the aluminum frame
•The grounding requirements must be
checked in accordance with the applicable
regulations and standards before work is
started.
•Use the marked 5.5 mm grounding holes to
ground the anodized frame. Use one M5 nut,
two M5 cut washers, one M5 plain washer,
one M5 spring washer, and one M5 bolt and
the copper wire. All nuts, bolts, and washers
are type M5 and should be made of stainless
steel.
•Put the bolt through the cup washer and
wrap the copper wire around the bolt. (Note
that the copper wire cannot be attached
directly to the aluminum.)
•Put the bolt through the cut washer and then
through the hole in the aluminum frame.
•Add the spring washer and nut on the other
side of the bolt and tighten to secure all parts.
The tightening torque should be 4~4.5 N•m.
Approve the use of UL-467
certified bonding and grounding
devices, including Burndy
(formerly Wiley Electronics) Washer
Electrical Equipment Bonding (WEEB) and
similar devices, such as barbed washers,
that meet the requirements of UL-467 as
suitable for electrical bonding and grounding
PV modules to PV mounting systems.
•Other grounding methods may be allowable
when tested with the racking system per UL
2703 requirements.
•Please don’t drill any additional grounding
hole on the frame of the modules.
•The frame rails have pre-drilled holes
marked with a grounding sign. These holes
should be used for grounding purposes and
should not be used for mounting the
modules.
8 Maintenance
It is required to perform regular inspection and
maintenance of the modules, especially within
warranty scope. It is the user’s responsibility to the
report to the supplier regarding the damages found
in time.
8.1 Routine inspection
Regular inspections should be made to see if the
photovoltaic modules in the photovoltaic array are
damaged, such as glass breakage, cable breakage,
junction box damage, cell damage, backplane
breakage and other factors that lead to functional
and safety failures of photovoltaic modules. When
the above problems occur, the supplier must be
notified in time to replace the same type of
photovoltaic modules.
It is recommended to perform a preventive
inspection every 6 months, and do not replace the
components of the photovoltaic module without
authorization. If electrical or mechanical
performance inspection or maintenance is required,
it is recommended that qualified professionals
perform the operation to avoid electric shock or
personal injury.
Routine maintenance measures should be taken to
keep the photovoltaic modules free of snow, bird
droppings, seeds, pollen, leaves, branches, dust,
stains, etc.

8.2 Photovoltaic module cleaning
If the PV module has a sufficient tilt angle (at least
15°), it is usually not necessary to clean the PV
module (rain will have a self-cleaning effect). If there
is a lot of dirt on the surface of the photovoltaic
module, which has seriously affected the power
generation, use water without detergent and a soft
sponge or brush to rinse the photovoltaic module
array when it is cool throughout the day. Do not
scratch or wipe the dust when it is dry, otherwise it
will cause tiny scratches. If there is snow, you can
use a brush with soft bristles to clean the surface of
the photovoltaic module.
For more detailed instructions related to cleaning
and maintenance, please refer to the "Photovoltaic
Module Cleaning Manual".
