  • Page 8: Electrical Performance Safety

    The application level of LONGi Solar module is Class Ⅱ, which can be used in systems operating at > 50 V DC or >240 W, where general contact access is anticipated; When the modules are for rooftop application, it is necessary to take the overall fire rating of the finished structure as well as operation and maintenance into account.
  • Page 9: Operation Safety

    Please refer to local laws and regulations before installing modules and abide by requirements on building fire protection. According to the corresponding certification standards, the fire rating of LONGi Mono-facial modules is UL Type 1 or 2 or IEC Class C, the fire rating of LONGi bifacial modules is UL Type 29 or IEC Class C.
  • Page 10: Installation Conditions

    Do not install modules at places that are possible to be flooded. • LONGi suggests that modules be installed in the working environment with the temperature of -40℃ to 40℃ of which is the monthly average highest and lowest temperature of the installation sites. The extreme working environment temperature for modules is -40℃...
  • Page 11: Selection Of Tilt Angles

    If the modules output power meets the acquired load under the period of the worst irradiation in the year, the modules should be able to meet the load of the whole year. If the LONGi modules are used in grid-con-...
  • Page 12: Mechanical Installation

    Module and bracket system connection can be realized by mounting holes, clamps or embedded systems. Installation shall follow the demonstration and suggestions below. If installation mode is different, please consult LONGi customer service personnel and obtain approval. Otherwise, modules may be damaged and limited warranty will be invalid. (* Note: regarding to Anti-Soiling modules only, short edge design has applied on prevention of dust from accumulating on modules, therefore , do not install at the short edge.
  • Page 13: Bolts Mounting

    5.2.1 Bolts Mounting The LONGi’s module has mounting holes matching M6 and M8 bolts. See Figure 4 for installation details and corre- sponding hole positions. Mounting Diagram Applicable for modules 790mm (790 hole) 400mm (400 hole) Use M6 bolts LR5-72HPH/HTH/HBD/HGD/HTHF-xxxM*...
  • Page 14: Clamp Mounting

    For framed PV module, it is recommended that the length of the clamp be at least 50mm, the clamp must maintain an overlap of 10-12 mm with the frame of the module (For clamp installation with an overlap of less than 10mm, LONGi technicians need to be consulted for assessment).

    DC electric parts. (LONGi modules maximum system voltage is DC1000V/DC1500V---ac- tually system voltage is designed based on the selected module and inverter model.) The correction value of VOC can be calculated by the following formula.
  • Page 22: Connector

    6.4 Bypass diode LONGi solar module junction box contains bypass diode which is in parallel connection with the cell string. If hot spot occurred, the diode will come into operation to stop the main current from flowing through the hot spot cells in order to prevent module over-heated and performance loss.

    The copper core wire used for the grounding clamp is recommended to be 12 AWG. And copper wires cannot be pressed during installation in case of damaging. The following is one of the recommended grounding methods of LONGi modules: ◆...
  • Page 24: Operation And Maintenance

    Mounting holes on modules that are not occupied can be used for installing grounding devices. The third party grounding device can be used for grounding of LONGi modules but such grounding method shall be proved to be reliable. Grounding device shall be operated in line with stipulations of the manufacturer.
  • Page 25: Module Appearance Inspection

    Do not use acid and alkaline detergents to clean modules. Do not use tool with rough surface to clean in any case. In order to avoid potential risk of electrical shock or burn, LONGi suggests cleaning the modules during early morning or evening with low irradiance and low modules temperature especially for the hot regions.
