The component of the MC connector system for photovoltaics are designed to allow time-saving and safe serial and parale wiring of PV modules for buildings integrated and free-standing solar installations.
The interlockable MC4 connector system :
Diameter 4mm,

System Voltage max. 1000V
Degree of protection connected IP67,
Easy installation,
locking system "snap in"
Temperature range -40°C to +90°C
MC4 is the name of the connection type on all new solar panels, providing an IP67 waterproof and dust proof safe electrical connection.
The MC4 connectors work best with 4mm and 6mm solar cable.
When you buy any new solar panel (usually over 30 Watts) it will be already fitted with two 500 - 900mm leads with MC4 connectors attached for you to get the power safely out of the solar panel.
But how do you get the power from the panel on an outbuilding roof to your controller 20 metres away ?
A more efficient way is to buy the cable which you can cut to the exact length you need and then attach MC4 connectors.
All you need is
1. A cable,
2. Male and female MC4 connector,
3. Wire strippers,
4. Some wire crimps and about 10 minutes of your time.
Strip the wire shorter than the metal crimp connector. There is a mark on the metal to indicate how far the other connector will enter into this one, if your cable extends past this mark in the connector you will not be able to join the MC4 connectors together.
Recommended cable stripping length is between 10 - 15mm.
The plastic housing has a non return clip inside and if you have not put the nut on the cable first you will not be able to get the plastic housing off without damaging it rendering it unsafe to use.
