5.2 Cables and Wiring
Renogy 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. Renogy recommends that only sunlight resistant cables be used
with the minimum wire size being 4mm
2
in diameter.

 Keep connectors dry and clean and ensure that caps are tightly
sealed before connecting modules
 Faulty connections can result in electrical shock so make sure to
fasten all connections securely.
 Renogy modules can be installed in landscape or portrait orientation.
Make sure that the proper distance between the panels and the
surface to allow for air circulation.

 Series Connections are just plug and play with the male and female
MC4 connectors
 Parallel connections will utilize MC4 branch connectors for
centralizing all positive and all negative connections.
5.3 Bypass Diodes
The junction boxes used with the Renogy modules contain bypass
diodes that are wired in parallel with the PV string cells. In the event the
modules experience partial shading, the diodes are activated to bypass
the current generated by the non-shaded cells, therefore limiting module
heating and performance losses. However, they do not protect the panel
from over-current. Over-current protections devices must be used when
connecting more than 2 modules in series.
If the bypass diodes are suspected of failure, installers or maintenance
personnel should contact the company (Renogy).

 In systems with more than two modules in series, high reverse
current can flow through cells that are shaded partially or outright
when part of a module is shaded and the rest is exposed to the sun.
