Solar Cable YSplitter for Parallel Solar Panel Connections This pair of MC4 Y connectors includes one MMF and one FFM connector for joining two solar panel cables in parallel to a single PV module. Designed for outdoor photovoltaic systems, these Ysplitters let you expand an array or increase current output without changing panel voltage. Key benefits Simple parallel connection: Join two 4 mm2 solar cables to one PV module quickly and securely with MMF and FFM connectors. Robust outdoor performance: Housings made from PPO and PC plastic with tinned copper pins resist heat, UV exposure, and corrosion for longterm outdoor use. Secure and weather resistant: Selflocking MC4 design provides a firm connection that is dust and water resistant for reliable field operation. power handling: Rated to 1000 V DC and 30 A, with low contact resistance to minimize loss and maintain stable power transmission under load. Features and specifications Connector set: 1 MMF and 1 FFM MC4 Y connector Cable compatibility: Designed for 4 mm2 photovoltaic cables Materials: PPO plus PC plastic housing, tinned copper pins Electrical rating: 1000 V DC, up to 30 A Mechanism: Selflocking system for secure mating Environmental: Dust and water resistant suitable for outdoor installation Practical applications Residential rooftop solar: Parallel two panel outputs into a single PV input when matching voltage is required and higher current is needed. Solar array expansion: Add additional modules in parallel without reconfiguring system voltage or replacing existing wiring. Mobile and off grid systems: Use on RVs, boats, or remote array installations to combine panel outputs reliably in outdoor conditions. Why choose this product These Ysplitters are purposebuilt for PV installations that require durable, current parallel connections. The use of durable plastics and tinned copper pins, combined with a proven MC4 selflocking design, delivers a stable electrical connection and simple installation for diverse solar setups. Technical note Ensure cable and system design meet local electrical codes and the connectors are used within the specified voltage and current ratings.
