The Neopower MC4 One-in-Three Plug and Socket connectors are
engineered for efficient three-way parallel connections in solar
panel and photovoltaic systems. Featuring IP67 waterproof
protection, these connectors deliver reliable performance in
outdoor and challenging environments, shielding against dust,
moisture, and extreme weather. Constructed with tin-plated brass
contacts, they provide excellent conductivity, corrosion
resistance, and minimal power loss. The durable PPO housing
withstands high temperatures ranging from -40°C to 90°C, ensuring
long-term stability in demanding installations. Rated for DC 1000V
and current capacities of 34A for the plug and 30A for the socket,
these MC4 branch connectors are ideal for energy storage systems,
inverters, and large-scale solar arrays. Their compact, lightweight
design simplifies installation, while a lifespan of up to 3000
mating cycles guarantees dependable operation. Perfect for
expanding PV arrays without compromising efficiency, the Neopower
MC4 One-in-Three series is the trusted solution for professional
solar projects.
