T-Branch PV Connector

T-Branch PV Connector

The T-Branch PV Connector combines multiple photovoltaic string outputs into one DC connection point. Its molded branch body reduces loose cable runs, simplifies parallel wiring and provides a clean, space-efficient connection for rooftop and ground-mounted solar systems. Configurations from 2-to-1 to 4-to-1 support different array layouts, with voltage options up to 1,500 V DC.

Description
Technical Parameters

Product Features

  • Parallel string connection: Combines two, three or four PV string branches into a single output connection.
  • Molded branch construction: Integrates the branch junction into a compact body for improved mechanical stability and cleaner cable routing.
  • High-voltage capability: Supports photovoltaic systems with operating voltages up to 1,500 V DC when the selected model and complete connector assembly are rated accordingly.
  • Outdoor connection protection: Provides IP68 protection in the fully mated condition, helping resist dust and water ingress in exposed solar installations.
  • Flexible conductor options: Available for common PV cable sizes from 2.5 to 10 mm², depending on the selected connector and cable configuration.
  • Reduced installation work: Preassembled branch geometry minimizes field splicing and helps shorten installation time.
  • Multiple topology options: 2-to-1, 3-to-1 and 4-to-1 designs make it easier to match different module-string and inverter input layouts.

Cable and Connector Structure

 

Component

Function

Branch connector body

Molded junction that combines multiple input branches into one output path.

Male and female connector interfaces

Provide polarized, touch-protected DC connections to matching photovoltaic connectors.

Metal contacts

Carry the DC current through a low-resistance crimped electrical connection.

Sealing elements

Protect the connection against dust and moisture when the connectors are correctly assembled and fully mated.

PV cable leads

Provide flexible routing between the branch body, strings and downstream equipment.

Locking features

Help prevent accidental separation and maintain a secure mechanical connection.

Typical Applications

  • Residential rooftop arrays: Combines parallel module strings where roof space and cable-routing paths are limited.
  • Commercial solar rooftops: Organizes multiple string connections before routing the combined DC circuit toward an inverter or combiner equipment.
  • Ground-mounted PV systems: Provides a compact branch point for repeated array blocks and structured field wiring.
  • Solar carports: Supports neat cable management where PV conductors must follow beams, columns and enclosed routing paths.
  • System extensions and repowering: Adds compatible parallel strings when an existing inverter input and electrical design can accept the additional current.
