Leader 2 in 1 T Branch Connector, Solar Cable Connector 4mm

Leader 2 in 1 T Branch Solar Connector – 4mm²

The Leader 2 in 1 T Branch Solar Cable Connector (4mm²) is a highly efficient, plug-and-play solution for parallel solar panel connections. Engineered for durability and electrical reliability, this connector allows two solar panels to be joined into a single output reducing cable clutter, streamlining installations, and optimizing system performance.

Designed for use with 4mm² solar PV cables, this T-branch connector is compatible with standard MC4-type connectors and is built to withstand harsh outdoor environments. Its IP67 waterproof rating, UV-resistant housing, and flame-retardant materials make it ideal for long-term use in residential, commercial, or industrial solar PV systems.

Whether you’re expanding your off-grid system or setting up a rooftop array, the Leader 2 in 1 T Branch Connector ensures fast, safe, and reliable string connections.
