Full-Screen PV Module
Product Information:
The product is a PV Module, designed for electrical
installation. It has a maximum permitted system voltage of 1000V DC
(Option 1500V DC). The PV module application class is A. The module
should not be exposed to sunlight or other lights as it can produce
DC and cause an electric shock hazard if touched. Focusing sunlight
on the module via mirror or lenses is prohibited. The module has a
temples glass and backsheet for protection. Broken modules have
electrical risks and cannot be fixed or repaired, they should be
replaced in time.
Under nominal outdoor conditions, the current and voltage
produced by the module may be different from the datasheet. The
parameters in the datasheet are tested under STC condition.
Therefore, when determining other components’ rated voltage, wire
capacity, fuse rate, controller capacity, and PV module power
output relative datas of the PV system, please refer to the short
circuit current and open circuit voltage of the PV module and
design and install the system at 125% of the value as well.
To lower electric shock or burn risk, it is recommended to cover
the PV modules with opaque material during installation. The
installation and maintenance of the PV array should be handled by
professionals under isolating sunlight conditions. If batteries are
equipped in the PV system, they should comply with the battery
supplier’s suggestion.
The PV modules should not replace rooftop and wall material, and
partial replacement is also not allowed. They should not be
installed in areas where combustible gases may be present. Touching
the electrical parts of the PV module directly by hand is
prohibited, insulating tools should be used for handling electrical
connections. Dismantling any components of the DAH Solar PV module
personally is not recommended.
All the modules in the system should be connected to ground,
unless there are special stipulations. It is advised to refer to
International Electrical Standard or other International
Standards.
During installation, please ensure that the PV modules are not
subjected to large vibrations. Vibrations may cause module damage
or microcracks in the cells inside. The modules should not be wiped
with corrosive chemicals. When loads are working, the modules
should not be disconnected.
It is important to read the manual carefully and adopt relative
security measures when using the product.
Product Usage Instructions:
Climatic Condition: Do not install PV modules
in a flooded risk area. Avoid installing them in raining, snowing,
or windy weather conditions.
Angle Selection: The PV modules should be
installed in a place with maximum sunlight throughout the year. The
output power will be maximum when the modules are facing the sun
vertically. In the northern hemisphere, modules should be placed
towards the south as the first choice, while in the southern
hemisphere, they should be placed towards the north.

* Electrical performance parameter of module, such as nominal value of IscVoc and Pmas has ±3% random error compared with value of STC. The standard testing environment of module is: Irradiance 1000/m2Cell temperature 25Spectrum AM 1.5. * Normally, the current and voltage of module, will be a little higher compared with the value under STC, so when confirmed the associated parameters of solar system accessories, such as rated voltagecable capacityfuse capacity and module power, the corresponding short circuit current and open circuit voltage should be amplified by 1.25 times. * The maximum number of modules per series string must be calculated according to the requirements. The value of the Voc in the local expected minimum temperature cannot exceed the maximum system voltage value specified of the module (According to IEC61730 safety test, the maximum system voltage of DAH Solar Module is DC1000V) and other DC electrical components require values. * The Voc correction factor can be calculated according to the following formula: CVoc=1-Voc×(25-T), T is the minimum ambient temperature expected for the installation of the system, (% / ) is The temperature coefficient of the selected module Voc (according to the corresponding module data sheet). * If the reverse current which probably exceed the maximum fuses current of module passed through the module, the modules must be protected by an equivalent current protection device. If the number of parallel is more than or equal to 2 strings, there must be equipped an overcurrent protection device on each series of modules.
WARNING

* When Module exposed to sunshine or other lights, it can produce DC, in this case it may cause electric shock hazard if touch electrical parts.
* Focus sunlight on to PV module via mirror or lenses is prohibited.
* Temples glass and backsheet have protective effect, broken PV modules have electrical risks(electric shock and burnt), this kind of modules can not be fixed or repaired, should be replaced in time.
* Under nominal outdoor condition, the current and voltage produced by module are different with datasheet. The parameters in datasheet is tested under STC condition, therefore when determining other components rated voltage, wire capacity, fuse rate, controller capacity and PV module power output relative datas of PV system, please refer to the short circuit current and open circuit voltage of the PV module, and design and install the system in 125% of the value as well.
* In case to lower electric shock or burnt risk, it’s better to cover the PV modules by opaque material when installing.
* PV array installation job should be operated under isolating sunlight condition, installation and maintenance also should be handled by professionals.
* If batteries bank equipped in the PV system, it should comply with battery supplier’s suggestion.
* PV modules shall not replace rooftop and wall material, partial replacement is also not allowed.
* Don’t install PV modules in the area where may has combustible gases.
* Touch PV module’s electrical part by hand directly is prohibited, should use insulating tools to handle the electrical connecting.
* Don’t dismantle any components of DAH Solar PV module personally.
* Don’t lift modules by junction box or connecting cables.
* All the modules system should be connected to ground, if without special stipulations, please refer to International Electrical Standard or other International Standards.
* Please do not stand, sit, lying on modules, it may damage modules and also have injured risks. * Same size and specification models modules can only be connected together.
* During delivery please make sure transport tools or modules are not subjected to large vibrations, vibrations may cause modules damage or cells microcrack inside of modules.
* During all the delivery,don not allow modules to fall onto ground from transport tools, house or hand, this will damage modules or cells inside.
* Don’t wipe the module with corrosive chemicals.
* When loads are working, please do not disconnect the modules.
Please read the manual carefully
Please remember that you are using a electricity generation product, in order to avoid any accident, it should adopt relative security measures.
THANKS FOR CHOOSING DAH SOLAR
Installation Safety
– Please wear protective headcoats, insulated gloves, and rubber insulated shoes during installation job. – To avoid unnecessary touching of the PV module during installation. The surface of modules may over heated, it has risk of burnt and electric shock. – Due to the risk of electric shock, please do not proceed the installation work if junction box was wet. – Use insulated and dry tools, do not use wet tools. – Don’t use sharp tools to wipe the glass of PV module. It would leave scratches on the module.
