3.3.15 The
maximum reverse current is 20.25A for module with Isc≤9.61A and 27A for module with Isc
＞
9.61A. Application of the blocking diode and fuse in the combiner box are recommended for reverse
current protection when more than two strings are connected in parallel.
3.3.16 A certain gap is maintained between the PV module and the mounting surface to prevent the
mounting surface touching the junction box.
3.3.17 Standing on the solar PV module is forbidden and also prohibit installation tools or other objects
hitting surface of the solar PV module.
3.3.18 The solar modules are recommended to be installed over a fireproof and insulating roof covering
when installed on a roof.
3.3.19 PV cable connection cannot be too tight, it is recommended that the connector and the back sheet
have a certain gap.
3.3.20 In sandy regions, in order to avoid getting sand into the connector, we suggest to short circuit
module connectors before installation. If grains of sand get into the connectors, it may cause internal live
parts wear and tear and affect electrical safety.
4. Mechanical Installation
4.1 Installation Conditions
4.1.1 Extreme environment temperature range
：
-30
℃
to +50
℃
4.1.2 Operating temperature range
：
-40
℃
to +85
℃
4.1.3 Mechanical load on panels (e.g., snow/wind): The max tested snow/wind load is 5400Pa/2400Pa,
and the design load is 3600Pa/1600Pa under standard mounting system. For specific installation methods
and mechanical load test values, please refer to 4.3 detailed component installation instructions.
4.1.4 The modules mounting structure must be made of durable, corrosion-resistant and UV-resistant
material. Modules must be securely attached to the mounting structure.
4.1.5 In regions with heavy snowfall in winter, select the height of the mounting system, so that the
lowest edge of the modules is not covered by snow for any length of time. In addition, ensure that the
lowest portion of the modules is placed high enough so that it is not shaded by trees or other plants.
4.1.6 When the modules are supported parallel to the surface of a building roof, a minimum clearance
of 10 cm between the module frame and the surface of the roof is required to allow air to circulate behind
the modules and to prevent wiring damage.
