do so may result in damage to the module. Keep the connector dry and clean and
do not impact external force on the connector such as heavy snow, strong wind.
9. The maximum modules of one PV string N=(The maximum system
voltage)/[(Voc)*1.25], note the Voc is the value at the lowest temperature in the
project sites.
10. Suitable over current protection devices (string fuses etc.) must be installed when
connecting 3 or more strings in parallel configuration.
11. Under normal conditions, a module may be able to produce voltage and current
higher than in standard test condition. Accordingly, when determining component
rated voltage, conductor ampacities, fuse current and size of controls connected to
the PV output, the short circuit current and open circuit voltage value marked on
this module shall be multiplied by a factor (safety factor) of 1.25.*
·06··05·
*Note: The safety factor for component rated voltage, conductor ampacities, fuse
current and size of controls connected to the PV output is subject to the
meteorological conditions of project sites.
12. Select either method of fixing mentioned below depending on site conditions:
Screw-fixing system (Figure 5-a), Fixture-fixing system (Figure 5-b).
13. Installation method and location
1) Screw-fixing:
Fixing the modules on the bracket at 12 border prefabricated installation holes
(figure 6). All the fastening pieces are made of stainless steel. Installing holes A must
be fixed with bolts and customer can choose one of the installation B or C to use.

connected in series.
19. Artificially concentrated sunlight shall not be directed on the module.
20. Our modules have passed the salt mist and ammonia test (Please refer the test
report for detailed information) and can be installed in some corrosive
environments, e.g. sea side.
21. The modules should not be installed at the place which is less than 100 meters
from the seashore. If the distance of the seashore and the project site is
100~10000 meters, anti-corrosion application should be taken during the
installation and grounding processes.
15. The minimum separation between two modules shall be more than 10mm; when
installing on the roof, the recommended separation between the modules and the
roof surface is 100mm to allow for air flow around the modules. When installing on
ground mounts keep ground clearances to more than 450mm.
16. Grounding
1) Grounding method shall be consistent with the local standard and regulations. Any
grounding system/method, which is designed in accordance with relevant
international and local standards and regulations, such as UL2703, UL467,
IEC60335, NEC article 250 and section 690.V.43, etc. could be attached to the
modules.
2) In order to prevent electrochemical corrosion, material in contact with module
frames, should be properly selected and galvanic isolation provided where
necessary.
3) PID (Potential Induced Degradation) due to combined effects of high temperature,
high humidity and high voltage, is most likely to be observed in similar climates and
mounting surroundings such as India, Southeast Asia, floating designs. Expect for
equipment grounding, negative system grounding is strongly recommended as the
basic solution for PID phenomenon.
4) Grounding wire shall be the bare copper wire with simple surface treatment and no
insulation sleeve. Wire cable with cross-sectional area of 4mm2(10~12 AWG) and
ground clamp (such as Tyco, identification of product: 1954381-2) are
recommended(diagrammatic sketches are as follows).
17. When the connecting wires of the modules do not meet length requirements, a
correctly rated electrical cable that is designed and certified for long term outdoor
use along with the correct connectors can be used to extend the connections.
Match the same brand and type of module connectors to extend the connection.
The cross-sectional area for PV array wire must be no less than 4mm2, and the
connection system is IP67 rated.
7. Maintenance
