## Long description

ORNO PV connector Y-branch 4xMC4 splitter aw\_886401 is a passive photovoltaic connector designed to combine outputs from multiple solar panels or strings into a single parallel feed. The device features four MC4-compatible ports arranged in a Y-branch configuration, enabling quick and tidy parallel wiring in PV arrays. It is intended for use in systems that employ standard MC4-compatible connectors and can be installed on rooftop or ground-mounted solar arrays where reliable, weather-resistant electrical connections are required.
Advantages
The ORNO 4xMC4 splitter simplifies interconnection of panels by providing four MC4-compatible ports in a compact, Y-branch form factor that reduces cable clutter and installation time. Its passive design imposes no additional power conversion or electronics, ensuring minimal signal loss and inherent compatibility with MC4-equipped modules and extension cables. The connector housing is designed for outdoor use, offering protection against environmental factors typically encountered in solar installations and supporting straightforward parallelization of PV strings.
Suitable for
 Combining outputs of up to four solar panels in parallel
 Connecting multiple strings to a single inverter input or combiner box
 On-roof and ground-mounted photovoltaic installations using MC4-compatible connectors
 Small and medium residential solar systems requiring compact parallel wiring
Key specifications
 Connector type: MC4-compatible ports in Y-branch splitter arrangement
 Number of outputs: four parallel outputs
 Function: passive photovoltaic splitter for parallel connection
 Intended environment: outdoor-rated for solar array installations

How to use
Install the ORNO Y-branch splitter by connecting each panel or string lead with the corresponding MC4-compatible mating connector until a secure, audible click is felt. Align polarity correctly and ensure all connections are fully seated to maintain weatherproof integrity. Route and secure cables to reduce strain on the connector body, and place the splitter in a location that allows inspection and maintenance while minimizing exposure to concentrated water flow or debris accumulation.
Usage recommendations
Verify compatibility of MC4 connectors on your panels and extension cables before installation, confirm correct polarity to avoid system faults, and follow local electrical codes when integrating the splitter into the PV system. Periodic visual inspection of connections and cable strain relief is advised to maintain reliable operation.
