7. Especially for Fig. (e) mounting method, the modules may be mounted using clamps designed for solar modules refer to
Fig. (j), the modules must be supported along the length of the long edge, and should overlap the array rail by
10mm – 14mm
8. Especially for Fig. (f) mounting method which is not suitable for 35mm frame thickness of CHSM6610P and 45mm frame
thickness of CHSM6612P product series, clamp positions are important – the clamp centerlines refer to mark “D” which
must be between 50mm and 200mm from the end of the module.
4. Electrical Installation and Grounding
4.1 Installation
4.1.1
The electrical characteristics are within ±10 percent of the indicated values of Isc. Voc and Pmp under test conditions
(irradiance of 100mW/cm²,AM1.5 spectrum, and a cell temperature of 25°C).
4.1.2
The maximum system voltage for all module series is 1000 V for North American Market and 1000V for European
Market.
4.1.3 Connect quantity of modules that match the voltage specifications of the inverters used in system. Modules must
not be connected together to create a voltage higher than the permitted maximum system voltage under the worst
local temperature conditions.
4.1.4 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 values of Isc and Voc marked on this module
should be multiplied by a factor of 1.25 when determining component voltage ratings, conductor ampacities, fuse
sizes, and size of controls connected to the PV output.
4.1.5 Refer to Section 690-8 of the National Electrical Code for an additional multiplying factor of 125 percent (80 percent
derating) which may be applicable.
4.1.6 Each module (or series-connected string of modules) shall be provided with the maximum series fuse, specified as 10
A for the 5 inch cell module series and 15A for the 6 inch cell module series.
4.1.7 Use a special solar cable and plugs for installing the PV system and make sure that all connections are safe and tight.
The cable should be 4 mm2 (12AWG), and able to withstand the maximum possible system open-circuit voltage.
4.1.8
Bypass diodes are included in module junction boxes to avoid decreased module performance in the event of shade
or shelter. Please check the relevant product datasheet for the specific diodes of J-box.
