Stäubli MC4 Connector Pair

The original Stäubli MC4 is the world’s leading PV connector!



About the Stäubli MC4 Connector Pair:

Stäubli connectors are crafted with Swiss precision, offering optimal efficiency and long-term performance for small to large-scale PV systems. When selecting connectors, trust the original to rest assured that your operations will be safe and perform sustainably for decades to come.

By selecting the premium-quality MC4 PV connector of Stäubli for your PV projects, you are creating a solid foundation for success while minimizing risks and ensuring efficiency and profitability.

Constantly low contact resistance of the PV connectors is key for efficient operation and safe energy feed-in. Increasing contact resistance, e. g. due to deficient material characteristics, can weaken the efficiency of the entire PV system.

The core of the Stäubli PV connectors is the innovative MULTILAM contact technology. This unique contact principle stands out due to multiple contact points that improve connection quality and energy transfer thanks to its constant spring pressure and unique design. This results in constantly low contact resistance, ensuring safe and long-life operation and reduces downtime and service cost significantly.

This differentiating contact technology minimizes the risks of power loss, downtimes, hotspots, or even a fire that could lead to enormous reconstruction costs. The original Stäubli PV connectors of the MC4 connector portfolio are very stable in terms of temperature and show no heat accumulation.
