Product Features of MC4 T Branch Solar Panel Connector

The PV-EKB5 mc4 t branch solar panel connector is built for reliable, low-loss string combining in demanding outdoor PV installations:

Five-way branch design: one trunk output and five branch ports spaced 22 mm apart let a single mc4 parallel connector merge multiple PV strings without extra splice joints.
High voltage rating: 1000V (TUV) and 600V (UL) rated voltage with a 6kV (TUV, 50Hz, 1 min) test voltage for dependable dielectric strength.
30A suitable current: supports the combined string current of typical PV arrays within its rated limit.
Low contact resistance: tin-plated copper contacts keep resistance below 0.5 mΩ, reducing heat build-up and power loss while resisting corrosion.
IP67 protection: sealed against dust and temporary water immersion for outdoor rooftop and ground-mount use.
Durable, safe materials: PPO insulation with UL 94-V0 flame class and Safety Class II construction.
Wide temperature range: operates from -40°C to +85°C ambient, suitable for extreme climates.
Standard pin size: Φ4 mm pin dimension, designed against IEC 60068-2-52.

Commercial Applications of MC4 T Branch Solar Panel Connector

Installers choose the PV-EKB5 mc4 t branch solar panel connector wherever several PV strings must be joined into one DC feeder, cutting cable runs, connection points and installation time on commercial and industrial solar projects.

Applications & Use Cases:

Commercial and industrial rooftop PV systems: combine adjacent strings before the inverter or combiner input.
Ground-mounted and utility-scale solar farms: simplify string-to-feeder wiring across large arrays.
Solar carports and canopies: compact body saves space in tight cable routing.
Hybrid and off-grid DC systems: merge PV inputs ahead of charge controllers or hybrid inverters, keeping the total current within 30A.
Retrofit and expansion projects: add extra strings to an existing array through a single branch connector.

Dimensions and Wiring of MC4 T Branch Solar Panel Connector

The compact body of the PV-EKB5 mc4 t branch solar panel connector measures 107.5 mm in length and 107 mm across its five branch ports, with a uniform 22 mm pitch between ports. All dimensions below are in millimeters.

Dimension	Value (mm)

Wiring Notes

The five branch ports connect strings in parallel to the common trunk: voltage stays the same while string currents add up. Keep the combined current at or below the 30A rating.
The datasheet shows two complementary versions (pin-contact and socket-contact branch sides); choose the version that mates with your PV module or cable connectors.
Fit string-level protection (fuses or breakers) and follow local electrical codes and the installer’s instructions; do not connect or disconnect under load.
