MC4 connectors allow strings of panels to be easily constructed by pushing the connectors from adjacent panels together by hand but require the MC4 spanner to disconnect them to ensure they do not accidentally disconnect when the cables are pulled. Fuse holders, mounting brackets, cables, and MC4 connectors are all important parts of your system, used to connect your solar panels to your batteries, protect your solar and change the angle of your solar.
When the two connectors are coupled, the locking tabs slide into the locking slots and secure. Push the Two Connector pairs together such that the two locking tabs on the MC4 Female Connector align with the two corresponding locking slots on the MC4 Male Connector. The finished product should look like as shown in the above picture above. Now your MC4 connectors are ready to use. The process for female MC4 connectors is the same but be sure to use the correct contact. When the end cap is tightened, the internal rubber seal is compressed around the outer jacket of the cable and thus, provides water-tight sealing. Note: Keep in mind that solar panels come with the female plug marked ” + “, on the positive output lead from the solar panel.įirst hand tighten the end cap into the main housing plug, then finish the job with your MC4 Spanner Set. The plug on the right has the small MALE “pin” and the plug on the left has the FEMALE barrel/receptacle.
The terminology relates to the crimp terminals inside the plastic housing not the physical body of the plugs. It’s really confusing between FEMALE and MALE MC4 connectors because the one on the left clearly looks like a MALE and the one on the right clearly looks like a FEMALE. The Female version uses a different housing and metal crimp contact, but the rest of the parts are the same. There are five parts of an MC4 connector (from left to right in the photo above): MC4 Assembly & Disassembly Spanner Set ( Banggood / Amazon ) So call us today and we at Smart Security Y.C.Working with MC4 connectors requires a few specialized tools.ģ.
