elmex PV Solar 4-Rail Junction Box

elmex  PV Solar 4 - Rail Junction Box EPVJB-F is suitable for electrical connection from PV Crystalline module as a solution for easy and reliable interconnection from PV module to DC / AC converters. It has simple and cost effective assembly designed with snap fit locking arrangement with IP 65 protection requirement for PV industry. The Junction Box is provided with two cables each of 1-meter length, with elmex make straight male and female EMPV4 / EMPV4N connector for simple on-site wiring. PV Junction Box employs fast switching Schottky Diodes with a peak reverse voltage rating of 45 V. The diodes are soldered with PV rails using lead-free, high melting point solder alloy. PV ribbons from PV module can be connected with junction box rails by soldering process.
