Overview
Product Overview
The UH-PC-YB02 solar panel splitter connector provides a multi-branch wiring solution for photovoltaic parallel connections. Unlike conventional Y-branch connectors with individual branch junctions, this series uses an integrated cable assembly with multiple positive and negative connector leads.
Three configurations are available: 4-to-2, 6-to-2 and 8-to-2, corresponding to two, three and four paired PV input connections respectively. The appropriate configuration depends on the number of PV circuits, connector interface, cable specifications and system current requirements.

Three Branch Configurations
UH-PC-YB02 offers 4-to-2, 6-to-2 and 8-to-2 configurations to accommodate different numbers of paired photovoltaic connections.
Parallel PV Wiring
The assembly supports the parallel connection of compatible PV circuits through a common positive and negative connection pair. Electrical sizing must account for the combined output current.
Integrated Branch Cable Design
Multiple cable leads are arranged within one branch assembly, providing an alternative to installations using several separate Y-branch connectors.
Positive and Negative Connections
Each configuration provides corresponding positive and negative connector leads for the intended PV wiring layout. Correct polarity must be maintained throughout installation.
Multiple PV Installation Options
Different branch counts allow installers and OEM customers to select an appropriate cable assembly for their photovoltaic wiring requirements.

Applications
Where This Product Is Used
Solar PV Systems
Protection, connectivity and distribution components for photovoltaic arrays, string circuits and related solar DC systems.
UH-PC-YB02 is intended for photovoltaic installations requiring multiple compatible PV circuits to be connected in parallel. Typical applications include solar module interconnection, PV array extension wiring and selected DC-side branch connection arrangements.
The 4-to-2 configuration accommodates two paired connections, while the 6-to-2 and 8-to-2 versions support three and four respectively. The final wiring arrangement must comply with the electrical design and protection requirements of the PV system.
Installation
Installation Guidance
1. Select the 4-to-2, 6-to-2 or 8-to-2 configuration according to the number of PV circuits to be connected.
2. Confirm that the PV circuits are electrically suitable for parallel connection and that the downstream cable and equipment can carry the combined current.
3. Isolate the photovoltaic circuits before installation. Do not mate or disconnect connectors under load.
4. Identify the positive and negative connector leads and verify the polarity of each PV circuit.
5. Connect the corresponding PV leads using approved mating connector combinations. Ensure that all connectors are fully engaged and locked.
6. Route and secure the cable assembly to prevent excessive tension, bending or mechanical damage.
7. Verify polarity, connector engagement, wiring continuity and the required circuit protection before energizing the system.

FAQ
Frequently Asked Questions
What is the difference between 4-to-2, 6-to-2 and 8-to-2 solar splitter connectors?
The configurations provide branch connections for two, three and four paired PV circuits respectively. Each circuit uses a positive and negative connector, with a common positive and negative connection pair on the other side.
Is UH-PC-YB02 the same as a standard Y-branch connector?
Both are used for photovoltaic branch wiring, but UH-PC-YB02 uses an integrated multi-branch cable assembly. A standard Y-branch connector typically has fewer individual branch connection points.
Can the splitter connector be used with any solar panel?
Compatibility depends on the PV system voltage, current, connector interface, polarity and circuit design. Connector profiles that appear physically similar are not automatically approved for mating.
Does the splitter connector provide overcurrent protection?
The splitter assembly is a wiring component and should not be treated as an overcurrent protection device. Separate PV string protection may be required depending on the circuit design and applicable electrical standards.
Are different cable lengths or connection arrangements available?
Project-specific cable lengths and connector arrangements can be discussed for OEM supply. Availability and technical requirements should be confirmed before ordering.
