Connectors are typically attached by crimping, though soldering is also possible. The MC4 connector is UL rated at 1500 V DC and up to 95 A with the 6AWG PV Cable. MC4-Evo 2 has both UL and IEC certification ratings of 1500 V DC and up to 70 A with 10mm² PV Cable, depending on the conductor size used in pairs.
A front-on view of a typical pair of Tyco Solarlok solar panel connectors. The blue ring on the female connector indicates that it is keyed for negative polarity. The keys are the plastic ridges running along the probe on the right connector. The right connector is the female electrically, although it appears male mechanically.

The connectors are wired pin 1 negative, pin 4 positive. Often pins 1 and 2 will be negative, 3 and 4 positive for a higher current rating. Female connectors are used as supply and male connectors are used on loads.
In 2008, NEC banned the opening of PV connectors under load as the push-fit connectors were required to contain positive locking mechanisms controlled by certified, product-specific tools. The MC3 PV connector did not meet these requirements, but its successor, MC4 PV connectors , which were launched in 2004 provided the fundamental mechanism ...

Electric charge is a conserved property: the net charge of an isolated system, the quantity of positive charge minus the amount of negative charge, cannot change. Electric charge is carried by subatomic particles. In ordinary matter, negative charge is carried by electrons, and positive charge is carried by the protons in the nuclei of atoms ...
