Ever wondered what the ‘MC’ in ‘MC4 connector’ stands for? It is ‘Multi-Contact’, the brand. They came up with the MC4 connector that is now the standard for every solar panel. Multi-Contact makes many more types of connectors, but it is those MC4’s that we in the renewable energy world are most interested in.
The company was founded in Basel, Switzerland in 1962, and has been part of the Stäubli Group since 2002. With a workforce of over 4,500 employees all over the globe, Multi-Contact has a presence spanning 25 countries, and agents in over 50 countries worldwide.
Solacity stocks MC4 connectors and PW-Wire. We only stock the real, Multi-Contact brand MC4 connectors that are UL and CSA listed. If you have ever seen a molten imitation MC4 from Asia lying on a roof-top (and realized how close that came to burning the place down) you will know to stick with the real brand, even if they cost a bit more.
