Edge connectors on show at Solar Energy UK
An edge connector for solar panels will be on display from Multi-Contact at the Solar Energy UK exhibition in Birmingham this October. The slimline PV-JB/BF junction box can be mounted on the edge of the panel without obscuring any solar cells. Where the panel is intended for architectural use, this enables the connector and cabling to be hidden within the facade frame.
Suitable for module thicknesses between 5 and 9mm, the unit uses Multi-Contact's industry standard MC4 connector system and has four bus ribbon connectors. The heat management of the PV-JB/BF allows a bypass current of 17A with ribbons not exceeding 90°C, which reduces degradation of the EVA encapsulant.
Another connector on show will be the MC4-EVO 2, which minimises power losses thanks to an exceptionally high current carrying capacity of up to 69A. Its high voltage rating of up to 1500VDC also means that longer series strings can be used in PV arrays on large-scale solar projects. Suitable for cable cross-sections between 4 and 10mm2 (12 to 8AWG), the connector has a polyamide casing with improved impact resistance and enhanced sealing. Ammonia and salt spray resistance also enables operation in harsh environments.
Also exhibited will be the MC4-EVO AC three-pole AC connector for use with micro or nano PV inverters. Designed for module level and string level applications, its low profile allows it to fit within the panel framework, enabling modules to be stacked without the use of spacers. With a current carrying capacity of up to 32A, it has a rated voltage of 600 (UL) and 400VAC (IEC). Accepted cable cross-sections range from 1.5 to 4mm2.
Solar Energy UK takes place at the NEC, Birmingham, from 13th to 15th October 2015, and Multi-Contact can be found on stand D44.
