Branch Connector Series-1

Branch Connector Series-1

Branch Connector Series-1 is designed for photovoltaic systems where multiple PV circuits need to be connected through a common branch point. It provides a practical solution for organizing parallel PV connections in residential, commercial and other solar installations.

The connector is rated up to 1000V and 45A maximum output current, with IP67 protection and contact resistance below 5mΩ. It is designed for outdoor operating conditions from -40°C to +85°C.

Series-1 is available in several B4 configurations, including B4A-B4B, B4C-B4D, B4E-B4F and B4G-B4H, allowing the appropriate configuration to be selected according to the PV system connection layout.

What Does a Solar Branch Connector Do?

A solar branch connector is used to connect multiple PV circuits at a common connection point. It can help organize parallel connections between solar modules or PV strings without requiring multiple separate connection points.

The appropriate branch connector configuration depends on the number and arrangement of PV circuits in the system. For this reason, the connector configuration should be selected according to the electrical design and wiring layout of the specific PV installation.

MC4-Compatible Solar Branch Connector

Branch Connector Series-1 is designed as an MC4-compatible solar branch connector for photovoltaic applications. It provides a practical connection solution for PV circuits where a branch connection is required.

Compatibility should not be determined by physical fit alone. Electrical, mechanical and certification requirements should also be considered when selecting mating connectors.

When connecting products from different manufacturers, the specific connector combination should be verified before installation to ensure that the intended requirements are met.

Applications

Residential Solar PV

Suitable for residential photovoltaic systems where multiple PV circuits require a branch connection.

Commercial Solar

Suitable for commercial rooftop and other distributed PV installations requiring organized PV circuit connections.

Distributed PV Systems

Designed for distributed solar applications with different PV circuit layouts.

Solar Power Projects

Suitable for photovoltaic installations where the system design requires branch connections between PV circuits.

Choosing the Right Branch Configuration

The appropriate branch connector configuration should be selected according to the number and arrangement of PV circuits in the system.

Before ordering, confirm:

• The required branch configuration
• PV system voltage
• Maximum operating current
• Cable and mating connector specifications
• Applicable certification requirements

For projects with non-standard wiring layouts, TREASUN can provide product information and technical support to help confirm the appropriate configuration.
