Difference between MC3 and MC4 connectors


MC3 connectors are a mostly obsolete type of single contact connector commonly used for connecting solar panels. Can be installed on any conventional solar module junction box, solar combiner box interconnection or added to solar modules with existing MC3/Type 3 connectors for extended distances. Greatly speeds up installation of solar array.

Features of MC3 connectors:

With excellent ageing resistance and UV endurance, it can be used in harsh environments.

The cable connects by means of a rivet and lock.
