Installing the module
J
Proper wiring
Never open the connection box! The modules
are already fitted with all necessary wires and
connectors.
J
Ensure correct wiring:
The integrated connection cables are UV resistant.
The conductor cross-section of the connection
cables is 4 mm². For wiring, the connection cables
are fitted with prefabricated connectors, which
are protected against reverse polarity.
Keep the total area of all conductor loops as
low as possible in order to reduce the voltages
due to indirect lightning strikes. Always carry
out a careful final check of the wiring prior to
commissioning the generator. If the measured
open circuit voltage diverges from the default
value, a wiring error has occurred. Check for
correct polarity.
Merge the connectors together correctly:
Connectors may only merged together when
dry. Also make sure that a gap-free connection is
possible.
In order not to exceed the max. system voltage at
-10 °C, the 54-cell Professional and Vision modules
must not be connected in series with more than
24 modules. With the Professional and Vision 60
modules, max. 22 modules may be connected
in series. Additionally, the requirements of the
inverters must be observed.
When connecting the modules in parallel, a
corresponding overcurrent protection must be
used. This can be achieved with direct current
fuses, which prohibit return currents greater than
12 A.
Furthermore, the connection requirements and
design regulations of the inverter manufacturer
must be observed.
J
Only use suitable materials:
The system may only be wired using special
solar wires and suitable connectors. It is very
important that all necessary materials are in a
flawless electrical and mechanical condition. Only
use single core wires and chose an appropriate
conductor size in order to minimize the voltage
drop. For further connections of the modules only
appropriate cables with a minimum conductor
cross-section of 4 mm² must be used.
J
Protect the wires from adverse
environmental effects:
Only use UV-resistant cable ties for the
attachment of the wires to the mounting system.
Protect the exposed wire from possible damage,
e.g. by routing it in plastic tubes. Avoid direct
exposure to sunlight.
Under usual and expected conditions, a PV
module can generate a higher current and/or
higher voltage as stated with the standardized
test conditions. For this reason, the Isc and Uoc
values specified on the module must be multiplied
by a factor of 1.25 to determine the rated voltage
values of conductors, fuse values and the size
of control systems connected to the PV module
output.
J
Make sure connectors are mounted
correctly
To ensure that connectors of the same model are
used, it is permitted to sever the module cable just
before the module connector plug and mount one
of the other connectors approved by Solar-
Fabrik AG.
The KSK4 connector (manufactured by Kostal) is
approved for use by Solar-Fabrik AG.
Additional connectors upon request. Consult your
Solar-Fabrik AG sales representative if you have
any questions.
The connector must be installed according to the
mounting instructions provided for the connector.
Note that all work must take place on the ground
when attaching the module connector.
Always make sure that the module is disconnected
from the generator field while carrying out work.
Make sure that the photoactive side of the
module remains face down while work is carried
out to ensure that voltage is kept at an absolute
minimum.
The full product warranty for the module remains
valid as long as all mounting instructions are
followed and the installation is carried out by a
specialist technician.
It is not permitted to combine incompatible
connectors from different manufacturers.
Combining connectors from different
manufacturers will render the product warranty
void.
