MC4 connectors

  • MC4The MC4-type connector connects individual PV modules in both series (strings) and parallel in large arrays, typically connecting 4, 6 and 10 mm2 copper energy cables.
  • Easy to connect and disconnect, they can be delivered as factory-fitted and tested harnesses or installed onsite.
  • They can also be used in combiner boxes and as branch joints to link up diverse strings to easily expand an array.
  • Very light, UV- and high-temperature resistant, MC4s allow utilities to save time and money during installation, plan for future growth and protect their infrastructure investment.

Both Energyflex® cables and MC4 connectivity have been provided for France’s 300 MW Cestas solar plant near Bordeaux, which is the largest single array on the European continent.
