Solar panel cable pack with Ysplitter and MC4 connector kit for MC4compatible solar systems. Durable, weatherproof, and ready for quick onsite installation. Key benefits Combine two panel outputs into one input using the Ydesign 1Y2 splitter to simplify wiring and reduce the number of runs. IP67 waterproof connectors and sealing rings provide reliable outdoor protection for rooftop, RV, boat, and groundmounted arrays. Fast, secure connections with selflocking MC4 contacts and included wrenches to speed installation and reduce tool needs. Longlasting performance from corrosionresistant tinned copper conductors and UV resistant insulation. Features and materials Rated voltage: DC 1000 V. Current capacity: 30 A. Conductor: tinned copper for improved conductivity and corrosion resistance. Conductor cross section: 4 mm2. Temperature range: 40 C to 194 C for wide environmental tolerance. Insulation: PPO; outer jacket: PVC with antiaging, antiUV, antiozone, and antiwear properties. Flame retardant material. Security level: Level II. Tensile strength: 100 N. IP67 waterproof sealing on MC4 connectors. Color coding makes male and female connectors easy to identify. Kit contents 2 x 5 m cables, 4 mm2, fitted with S1 solar plug pairs in Ysplitter configuration (1Y2). S6 MC4compatible connector pair set for panel or system terminations. MC4 key S2 wrenches (two compact wrenches) to assist connector assembly and tightening. Performance and compatibility Designed for use with MC4compatible solar panels, inverters, combiner boxes, and charge controllers up to DC 1000 V and 30 A per line. Ysplitter lets you parallel two panel strings into a single input where compatible with system design. Durable construction suits outdoor, marine, and mobile solar installations. Typical use scenarios Residential rooftop array: parallel two panels into one MPPT input to match charge controller inputs and simplify roof wiring. RV or boat solar setup: durable, UVresistant cables and waterproof MC4 connections for mobile, salt air exposure conditions. Small offgrid or portable systems: quick onsite assembly using included wrenches and selflocking connectors to save installation time. Installation notes Confirm system voltage and current ratings before connecting; connect only to compatible MC4type equipment. Use the included MC4 keys to fully seat and lock connectors for secure electrical and waterproof performance. Colorcoded plugs help prevent reversed polarity during assembly. This kit supplies the cables, connectors, and basic tools needed to create secure, weatherproof MC4 connections and to split two panel outputs into a single run while meeting the stated electrical and environmental specifications.
