Ä
Maintain an interval of at least 10 mm between two modules along the short side
Ä
Maintain an interval of at least 5 mm between two modules along the long side
MOUNTING OPTIONS CL1
Ä
Ensure, that the subconstruction does not run below the junction box.
Ä
Ensure, that the connection cables of the junction box don‘t run between laminate and substructure.
MOUNTING OPTION FB1
Ä
Use M8 corrosion-proof screws and washers (min. diameter 16 mm).
Ä
Ensure, that the connection cables of the junction box don‘t run between laminate and substructure.
•
The fastening points are located on the backside of the module frame.
Module Selection
For detailed key electrical data, please refer to the actual
data sheet referring to the relevant Module (available at
www.q-cells.com).
Ä
Only connect modules of the same type and the same
power class.
Safety Factor
During normal operation, a module may generate a greater
current and / or higher voltage than that determined under
standardized test conditions. Please use a safety factor of
1.25 for the following:
•
Calculating the voltage measurement values (V
oc
) of
components
•
Calculating the current measurement values (I
SC
) of
conductors
•
Sizing of control systems connected to the outlets of
the solar modules
Ä
Please follow the valid national guidelines for the
installation of electrical systems.
Series Connection
Connection of modules in series is only permitted up to
the maximum system voltage as listed in the applicable
data sheet of all the relevant modules to be installed.
Ä
Take into account all possible operating situations and all
relevant technical norms and regulations when designing
the system. It has to be ensured that the maximum
system voltage, including all necessary safety margins,
is not exceeded.
Ä
Take the voltage limit of the inverter into account when
determining the maximum number of modules in the
string.
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 an inverter or MPP tracker.
2) Layout with string fuses :
place fuses for each string of modules at the plus and
minus ends. Observe the maximum permitted number
of strings as indicated in the specifications provided by
the respective string fuse manufacturer 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.
