PFCTART

PFCTART Y Branch Solar Panel Cable Connector IP65

SKU CH-N829-Y1478

Y-branch MC4 connector pair parallel-connects solar panels with IP65 waterproof seals and UV-resistant, high-temperature materials

  • TypeSolar Panels
  • Parallel-connect multiple panels with a simple Y-branch plug-in
  • Tool-free assembly and removal for quick installation
  • IP65-rated double seal rings block water and dust
  • Electron-beam cross-linked compounds resist UV, ozone and hydrolysis
  • High current and voltage load capacity with low contact resistance

Y-Branch MC4 Solar Connector

This PFCTART Y-branch adapter joins two MC4 solar-panel leads into a single parallel circuit. The moulded body uses electron-beam cross-linked compounds that resist UV, ozone and hydrolysis while remaining flexible in cold conditions. Double seal rings provide an IP65-rated barrier against dust and water ingress. The pair ships ready for immediate field assembly.

Installers needing a quick parallel link

Solar installers who want a tool-free, weatherproof parallel connection will appreciate the plug-and-play design and high current capacity. Buyers who require series wiring, a different branch count, or non-MC4 interfaces should look at other connector types because this unit only supports a 1-to-2 MC4 parallel arrangement.

Tool-free push-fit assembly

Each connector half clicks together by hand; no crimping tool or spanner is needed for the basic mechanical lock. The most common issue is insufficient seating of the double seal rings, which can compromise the IP65 seal if the cable insulation diameter falls outside the compatible range.

Questions about this item

What MC4 connectors must I already have on my solar panels to use this Y branch?

Each panel needs a standard MC4 male and female pair so the Y branch can plug directly into them and parallel the strings.

Will the IP65 rating hold up if I keep older MC4 cables that have seen years of sun?

The connector uses electron-beam cross-linked compounds that resist UV, ozone and hydrolysis, so it stays sealed alongside aged cables.

How can I confirm the parallel connection is working after I plug everything in?

Measure the combined string current at the charge controller; it should equal the sum of each panel’s operating current.
