Ensure that the wiring is correct before starting up the
system. If the measured open circuit voltage (Voc) and
short-circuit current (Isc) differ from the specifications, this
indicates that there is a wiring fault.
When modules have been installed, but the system has not
been connected to the grid yet, each module string should
be kept under open-circuit conditions and proper actions
should be taken to avoid dust and moisture penetration
inside the connectors.
For double glass modules, Canadian Solar offers several
cable length options to match various system
configurations, in case a jumper cable is needed, please
contact your Canadian Solar sales representative.
Cables should always be fastened on module frames or
mounting rails, in order to avoid shading on the rear side of
bifacial modules.
In case where a cable connection method not included in
below table is used, please confirm suitable cable length
with Canadian Solar’s sales representative.
On below figures, bold lines represent cable installation
pathways, while + and - connector correspond to positive
and negative module terminals respectively.
