Stäubli expands MC4 portfolio with connectors for battery storage systems

Swiss connector manufacturer Stäubli Electrical Connectors GmbH has expanded its MC4 portfolio of PV connectors to include a connection solution with DC connection for battery storage systems. The »MC4-Evo stor« completes the MC4-Evo 2 product series as an extension to the DC 1,500 V portfolio.
This mateable connection between inverter and storage system has a 45° rotated mating face to ensure a fail-safe installation. It is not possible to connect the MC4-Evo stor to an MC4 or MC4-Evo 2 cable coupling as used in the PV string or at the battery output on the DC side of the inverter. The new MC4-Evo stor connector solution includes a cable coupler and a surface-mount receptacle, each mounted on the inverter and battery storage device. Like all MC4 connectors from Stäubli, the MC4-Evo stor meets the requirements of IP68 protection class.
