Example for mounting the PV modules to the substructure:
1. Stainless steel M6 nut
2. Stainless steel spring washer
3. Stainless steel M6 t-head bolt
We recommend using a torque wrench for installation. In example B, the tightening
torque (using stainless steel M6 bolts) should be around 15-20Nm. Use the existing
holes for securing the module and do not drill additional holes (doing so would
void the warranty). Use appropriate corrosion-proof fastening materials.
ELECTRICAL INSTALLATION
Cables and Wiring
Our modules are equipped with two (2) stranded, PV-rated, output MC4 cables.
The positive connector is a male connector and the negative connector is a female
connector. These wires by themselves are rated for series connections, but could
be adapted to hold parallel connections with an extra component such as a
combiner box or an MC4 adaptor for parallel strings. We recommends that only
sunlight resistant cables be used with the minimum wire size being 2.5mm2 in
diameter.
MC4 cables are intended for use on the output wiring of a module or panel and
comply with the Standard for Connectors for use in Photovoltaic Systems, UL 6703,
see module literature for appropriate mating connectors.
