Minimize risk. Maximize return.
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 simultaneously 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, eg due to deficient material characteristics, can weaken the efficiency of the entire PV system.
Advanced contact technology
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 the 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 a power loss, of 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.
It pays off to trust the original
Today, more than half the world’s cumulative PV capacity is connected with our components. The Original MC4 by Stäubli offers unrivaled quality, durability and reliability for all types of PV installations.
Stäubli has continually set the benchmark for PV connectors in the solar industry. In 1996 beginning with the launch of the original MC3 and then the MC4 PV connector in 2002. Globally, over 2 billion Stäubli connectors have been installed in solar power plants – and our growth continues thanks to our partners who recognize that quality pays off both short term and in the long run.
Utilizing our innovative and patented MULTILAM contact technology, the core of Stäubli PV connectors comes with multiple contact points to improve connection quality and energy transfer. Thanks to MC4’s unique design and constant spring pressure, the connectors offer low contact resistance to ensure safe and long-life operation. What’s more, the connectors are very stable in terms of temperature and demonstrate no heat accumulation, which can significantly reduce downtimes and service costs.
