equivalent plug connections for the wiring.
Only use special, UV-resistant solar cables and suit-
able connectors. Do not bend the cables and observe
the minimum bending radius. Please make sure that
the cables are laid such that they cannot rub against
sharp-edged objects or
roof tiles. UV-resistant cable ties, for example, are
suitable for fastening. Some mounting systems also
have special cable fastenings and guides. Make sure
the the cables are not installed under tensile stress.
Replace damaged cables.
If possible, ensure short cable lengths to minimise
intrinsic losses.
Please check the open circuit voltage and the short
circuit current for each installed strand (see also
section 4.4).
4.4 tEst
Test all electric and electronic components of the sys-
tem before use. Follow the instructions in the manuals
provided with the components and equipment.
Perform a test of the open circuit voltage and short
circuit current before connection of the system.
opEn CirCuit VoltagE
Check the open circuit voltage of each strand with a
digital multimeter. The measured values should corre-
spond with the total of the open circuit voltage for the
individual modules. You will find the nominal voltage in
the datasheet of the module used*. If the measured
value is substantially lower than the expected value,
continue in accordance with the section "Trouble-
shooting at low voltage".
short CirCuit CurrEnt
Test the short circuit current of each series circuit.
This can be measured directly with a digital multim-
eter, which is connected to two clamping plates of the
series circuit or module, or with any load, such as e. g.
PV lighting, in order to carry out a rough measure-
ment. Please make sure that the nominal scale of the
ampere meter or the rated current of the load must
amount to 1.25 times the rated short circuit current
of the series module. You will find the rated current
in the datasheet of the module used. The measured
value can vary strongly depending on the weather,
time of day and possibly the shade.
* The electrical values of the provided individual measurements al-
located to the respective serial number are decisive.
