Product Features of MC4 T Connector

The MC4 T connector is engineered for dependable parallel wiring in photovoltaic systems. Key features include:

Three-to-one branching: this MC4 T connector combines three solar strings into a single output, reducing cable runs and simplifying string-combining layouts.
High electrical rating: suitable current of 50A with a rated voltage of 1000V (TUV) and 600V (UL), tested at 6kV (TUV, 50Hz, 1 min).
Low contact resistance: tin-plated copper contacts keep resistance below 0.5mΩ to limit power loss and heat at the junction.
IP67 protection: the sealed body resists dust and temporary immersion, suitable for outdoor roof and ground-mount arrays.
Durable PPO insulation: flame class UL 94-V0 and safety class II, with an ambient temperature range of -40°C to +85°C.
Standard 4mm pin: Φ4mm pin dimensions match common solar DC connector systems for straightforward plug-in installation.

Commercial Applications MC4 T Connector

In commercial and utility-scale solar projects, the MC4 T connector lets installers branch DC circuits quickly while keeping connections sealed and consistent. A 3 to 1 solar branch connectors layout like this one cuts the number of home-run cables and speeds up array commissioning.

Applications & Use Cases

Combining parallel PV strings into one input on a string inverter or combiner box.
Reducing cable length and connection points in rooftop, carport and ground-mount solar arrays.
Branching DC output from multiple panel groups in commercial and industrial PV installations.
Expanding or retrofitting existing PV strings without replacing the main DC trunk cable.
