PV MC4 Y-Branch Connector ORNO aw_890647 — 3x MC4 solar panel splitter

ORNO MC4 Y-branch connector aw_890647 is a 3x MC4 solar panel splitter designed for use in photovoltaic systems to combine or distribute DC connections between modules. The splitter provides three MC4-compatible ports that allow parallel connection of solar panels or extension of existing strings without modifying individual panel leads. It is intended for outdoor installation in standard PV arrays that use MC4 interfaces and provides a compact, plug-and-play solution for creating branch circuits in a solar field.

Advantages

The connector supports three MC4-compatible plugs, enabling secure and quick parallel wiring of multiple solar panels while maintaining polarity and water-resistant connections. Its compact Y-branch form factor reduces cable clutter and simplifies on-site wiring and expansion of arrays. The device is compatible with common MC4 housings and contacts, which helps ensure interoperability with typical PV components and faster installation times.

Suitable for

• Parallel connection of two or more solar panels to a single input
• Expanding existing PV strings without cutting cable harnesses
• Field installations where standard MC4 connectors are used
• Temporary or permanent branch circuits in rooftop or ground-mounted arrays

Key specifications

• Connector type: 3-way MC4-compatible Y-branch splitter
• Application: DC connections for photovoltaic modules
• Contact arrangement: three MC4-style ports for plug-and-play mating
• Environmental protection: designed for outdoor PV use with sealed connections (water-resistant)
• Compatibility: conforms to common MC4 interface dimensions for interoperability with standard PV cables and connectors

How to use

To install, unplug panels and ensure the PV system is de-energized before handling connectors. Plug the MC4 male and female ends of the panels into the corresponding ports of the Y-branch connector, observing correct polarity. Ensure each mating pair clicks into place and that the seals are fully engaged. Route and secure cables to prevent strain on the connector and avoid sharp bends or abrasive contact. After connection, verify continuity and polarity with appropriate testing equipment before re-energizing the circuit.

Usage recommendations

Use the splitter only with compatible MC4-type connectors and PV cables of appropriate cross-section. Install in locations that avoid prolonged mechanical stress and inspect connections periodically for corrosion, damage, or loss of sealing. Follow all local electrical codes and safety procedures when integrating the connector into a photovoltaic system.
