PV Y-Branch Connector ORNO Orno Rozdzielacz 2xMC4 Y-type for photovoltaic panels

Orno Rozdzielacz 2xMC4 is a Y-type PV branch connector designed to split a single MC4 input into two MC4 outputs for photovoltaic panels. It enables parallel connection of solar modules and provides a compact, weather-resistant junction compatible with standard MC4 plugs. The connector is intended for use where reliable parallel splitting of panel strings is required in rooftop installations, ground-mounted arrays, or small commercial photovoltaic systems.

Advantages

The PV Y-Branch Connector offers straightforward plug-and-play connectivity with MC4-compatible cables, reducing installation time and minimizing the need for additional tools. Its Y-type design allows two outputs from one input without modifying module wiring, and its construction provides secure electrical contact and protection against environmental factors typically encountered in outdoor solar installations.

Suitable for

• Parallel connection of solar modules in rooftop PV arrays
• Splitting a single panel output to feed two strings or MPPT inputs
• Small commercial or residential photovoltaic systems requiring additional branch points
• Temporary or permanent outdoor solar connections where MC4 compatibility is needed

Key specifications

• Connector type: Y-branch for photovoltaic systems
• Compatibility: MC4-compatible male and female plugs
• Function: one input to two outputs for parallel wiring
• Application environment: outdoor solar installations
• Typical usage: parallel splitting of panel strings and cable junctions

How to use

Connect the MC4-compatible male plug from the photovoltaic panel or cable to the input side of the Y-branch connector, ensuring secure engagement until the locking mechanism clicks. Attach MC4-compatible female plugs from the two outgoing cables or panel strings to the Y-branch outputs, verifying that polarities match and connections are fully seated. After assembly, inspect connections for proper locking and route cables to avoid mechanical strain or chafing.

Usage recommendations

Ensure all PV system components are de-energized before making or breaking connections. Use only MC4-compatible, UV-resistant cables and check that the combined current of the parallel outputs does not exceed the rated current of system components and upstream protection devices.
