New crimp-free MC4 PV DC connector

With the MC4-Evo ready Stäubli launches a new crimp-free cable coupler within its Original MC4 product portfolio. The MC4-Evo ready is an easy-to-use and quickly-to-assemble PV connector for solar installations up to 1500 V DC.

The market leader and pioneer for PV DC connectors enhances its cable coupler portfolio and introduces the crimp-free MC4-Evo ready. The assembly of this new connector is crimp-free based on the snap-in-technology.
