Test procedure according to IEC 61215-2:2016 and UL 61730. Mounting options do not fulfill the requirements of the standards.
ATTENTION
Ä
The loads in the table are related to the mechanical stability of the solar modules. The mechanical stability of the mounting system
including clamps has to be evaluated by the system supplier. The listed test load values for Q CELLS were determined with the
following clamp parameters: clamp width = 1.58 in (40 mm) and clamp depth = 0.39 in (10 mm). The system installer is responsible
for the determination of location-specific load requirements.
Ä
Ensure, that the subconstruction does not touch the junction box (even under load). The clamps or insertion profiles etc. must
also not touch the glass (even under load).
Ä
Ensure, that the junction box's connection cables do not run between the laminate and the mounting rails.
Ä
CL1b: Minimum clearance between frame bottom edge and substructure: ≥ 1.18 in (30 mm), short rails are permissible if they
overlap with the module not more than 8.27 in (210 mm).t
Ä
A minimum support depth of 0.59 in (15 mm) is required on the back side of the module for IP1, IP2, CL2b, CL3, CL4 and CL5.
For the front side of the module for IP1 and IP2, this minimum support depth should be 0.39 in (10 mm).
Ä
For CL1, CL2a and CL3 with rails: Ensure that the module frame is fixed directly on the rail of the substructure (no spacer allowed
between the module and substructure).
Ä
The module bends under loads. Therefore, sharp objects (e.g. screws) must not be mounted near the module backside.
Ä
Use M8 corrosion-proof screws and washers (diameter ≥ 15.8 mm or ≥ 0.62 in) for FB1 and FB2 mounting.

2.4 ELECTRICAL LAYOUT
Module Selection
For detailed key electrical data, please refer to the product data
sheet for the respective product. (available at www.q-cells.us).
Ä
For maximum energy yields, mismatches of specified electric
current (I
) of more than 5 % should be avoided for all modules
MPP
connected in series.
Safety Factor
During normal operation, a module may generate a greater current
and / or higher voltage than that determined under standardized test
conditions. Accordingly, the values of I
and V
marked on the
SC
OC
module should be multiplied by a facot of 1.25 when determining:
•
the component voltage ratings,
•
conductor ampacities,
•
fuse sizes,
•
size of controls connected to the PV output.
Refer to Section 690-8 of the National Electrical Code for an
additional multiplying factor of 125 percent (80 percent derating)
which might be applicable.
Ä
Please follow the valid national guidelines for the installation
of electrical systems (refer to section 690-8 of the NEC for an
additional multiplying factor of 125 percent [80 percent derating]
which may be applicable).
Series Connection
Connection of modules in series is only permitted up to the maximum
system voltage as listed in the applicable data sheet.
Ä
Take into account all possible operating situations and all relevant
technical norms and regulations when designing the system.
This will ensure that the maximum system voltage, including all
necessary safety margins, is not exceeded.
Ä
Take the voltage limit of the inverter into account when deter-
mining the maximum number of modules in the string.
INSTALLATION AND OPERATION MANUAL SOLAR MODULES Q.PEAK DUO-G7.X – Q CELLS
Parallel Connection
Modules may be damaged by the occurrence of reverse currents
(caused by module defects, ground leaks, or defective insulation).
Ä
Ensure that the maximum reverse current load capacity indicated
in the data sheet is met.
In order to limit reverse currents that may occur, we recommend
using the following safety options:
1) Layout with a limited number of
parallel connected strings :
Without undertaking further current blocking measures, a maximum
of two module strings may be operated in parallel on a single
inverter or MPP tracker.
2) Layout with string fuses :
Use overcurrent devices (e.g. fuses) according to the relevant
standards in each string. Use gPV-fuses according to IEC 60269-6.
Observe the maximum permitted number of strings as indicated
in the specifications provided by the respective string fuse manu-
facturer and the technical guidelines.
NOTE!
When installing different product versions, the lowest minimum
permitted reverse current load capacity applies.
Inverters
Inverters with or without transformers may be used.
