Connecting The Mc4 Connector To Solar Wire; Mounting The Solar Panel(S) - Optex EcoOnline User Manual

6 Connecting the MC4 Connector
Your solar panel may have come with wire and MC4 connectors on the ends. You will need to source opposing MC4
connector plugs to make connections to the solar panels MC4 connectors. Please note the following when
connecting the back end of an MC4 connector to solar wire.
The MC4 connector metal pin must be crimped onto the solar wire using appropriate
Australian Standard crimping tools. We recommend you also solder the crimped connection
for better electrical contact, but only after a secure and tight crimp is performed.

7 Mounting the Solar Panel(s)

7.1 Mounting on Building Roof or Caravan
If the panels are to be mounted on a building roof always check council/building regulations
in your area. We recommend roof mounting of panels be performed by a qualified
professional that can advise on appropriate mounting means for your situation.
Generally, when mounting panel we also recommend:

Panel(s) should be mounted as close to the ground as possible for ease of maintenance, reduced wind
loading, shorter wire runs and a reduced chance of lighting strike

Electrical connections in junction box MUST be soldered on.

The underside moisture barrier should not be scratched as this the will severely limit panel lifetime.

Screwing self taping screws into the side of frame should not be used as a mounting means; use the bolt
holes on the back with locking bolt & nut set or commercially available mounting means.

Panels should be installed with 20mm to 50mm underside ventilation gap.
7.2 Portable/Folding Solar Camping Panel(s)
We recommend portable/folding panels are placed on a secure, flat, non-flammable surface
exposed to the sun. As a precaution do not place panels in dry flammable grass for example.
