The market-leading MC4 photovoltaic connector portfolio of Stäubli now features a DC connection solution for battery energy storage systems called MC4-Evo stor.

The new MC4-Evo stor for connecting battery energy storage solutions (Bess') completes the MC4-Evo 2 product series as an important element extension to the DC 1500 V portfolio.

This mate-able connection between the inverter and storage system simplifies installation and offers the well-known, long-term, robust, durable, and low-loss connection quality of the Original MC4 and MC4-Evo 2 DC cable couplers in the PV string. However, besides benefiting from time-proven Multilam contact technology, this energy storage connection solution from Stäubli has a 45-degree twisted mating face to ensure fail-safe installation. It is not possible to inter-mate the MC4-Evo stor with an MC4 or MC4-Evo 2 cable coupler used in the PV string or the battery output on the DC side of the inverter.

As with all Original MC4 Stäubli connectors, this Bess connection solution, the MC4-Evo stor, also has IP68 conformity and is an extremely robust product allowing for reliable and long-lasting operation even in harsh application environments.

The new MC4-Evo stor solution offers a cable coupler model and a panel receptacle mounted on the inverter and the battery energy storage device. Its quality and performance are confirmed by TÜV and UL certificates.
