Ensure that the total area of all conductor loops is
kept as small as possible to reduce voltages cau
-
sed by indirect lightning strikes. It is essential to
subject the wiring to a thorough final check before
the generator is put into operation. If the measured
open-circuit voltage deviates from the specificati
-
on, there is a connection error. Also make sure the
polarity is correct.
Insert the plug connectors correctly. Connectors
may only be inserted in a dry condition. Also make
sure that gap-free connection is possible. In additi
-
on, the requirements of the inverters that are used
must be observed.
If the modules are connected in parallel, appropri
-
ate overcurrent protection must be used. Fuses for
DC voltage must be used for this purpose, which
prevent a reverse current greater than 15 A.
Also observe the connection conditions and the
design guidelines of the inverter manufacturers.
Using suitable materials only
The system may only be wired with special solar
cables in accordance with DIN EN 50618 class 5
and suitable plugs.
It is of utmost importance that all materials used
are in perfect electrical and mechanical condition.
Only use single-core cables and select the appro
-
priate conductor cross-section to minimise the vol
-
tage drop.
Only use suitable cables with a minimum cross
section of 4 mm² for the further connection of the
modules. For longer distances, the cable cross
section must be adjusted accordingly. For cable
laying, also follow the specified requirements in
accordance with DIN VDE 0298-3.
Example 2 - Direct screw connection
Example 1 - Clamping vane
Proper cabling
Under no circumstances open the junction box.
The modules are already equipped ex works with
the necessary cables and connectors.
Ensuring correct wiring
The integrated connecting cables are UV-re
-
sistant. The connecting cables have a conduc
-
tor cross-section of 4 mm². For connection, the
connecting cables have pre-assembled connec
-
tors that are protected against reverse polarity.
