MC4 T Type

Our MC4 T Type Connector is a professional 1-in-2-out three-way connector designed for photovoltaic DC systems. Adopting a standard T-shape structure, it realizes one-input and two-output parallel connection. It is widely used in PV string parallel connection, power station expansion and distributed solar systems, ensuring high safety and stability.

The contact terminal is made of multi-lam tinned copper, providing excellent conductivity, low heat generation and strong oxidation resistance. The housing is constructed of PA/PC flame-retardant material and equipped with double-layer waterproof O-rings. It can work steadily between -40℃ and 85℃, with UV resistance and anti-aging properties suitable for harsh outdoor environments.

The connector fits PV1-F 2.5/4/6mm² solar cables and is equipped with a self-locking buckle for secure connection. It can be quickly installed and disassembled with standard MC4 tools.

It features good waterproofing, anti-loosening and reverse-polarity prevention functions. Suitable for residential, commercial, on-grid and off-grid solar systems, it is a safe and efficient connection accessory for solar wiring projects.

Strong Point

• No interruption to main circuit, flexible system expansion.
• Ideal for branching in long-distance series strings.
• IP67 protection, safer operation.

Usage environment:

MC4 T branch connector is specially designed for long-term outdoor operation and adapts to complex environments of photovoltaic systems. The operating temperature ranges from -40℃ to +85℃, ensuring stable performance in cold, high-temperature, desert and rooftop areas.

With IP67 protection grade, it is waterproof, dustproof, moisture-proof and salt-fog resistant, suitable for rainy, humid and coastal environments. The housing is made of UV-resistant and anti-aging PC/PA material, which avoids cracking or aging under long-term sunlight.

It is safe for indoor, outdoor, rooftop, carport and solar bracket installations. It is ideal for non-corrosive, non-explosive, non-vigorous impact environments, widely used in residential, commercial and distributed solar PV systems.

• Our MC4 T Type connector is independently developed and produced in our own factory, enabling us to fully understand customer needs and provide stable, customized connection solutions for PV systems.
• Featuring low contact resistance, it effectively avoids overheating and short circuits, ensuring safe and reliable operation. With IP67 waterproof, dustproof, UV-resistant and anti-aging properties, it adapts to -40℃ to +85℃ extreme climates, coastal salt fog and harsh outdoor environments.
• Fully compatible with standard MC4 connectors, its self-locking structure allows easy installation, firm mating and low maintenance. Using flame-retardant housing and high-quality tinned copper terminals, it delivers long service life matching 25-year PV system lifespan.
• With professional R&D and strict quality control, we can flexibly meet customized demands, making it the optimal choice for residential, commercial and distributed solar power plants.
