MC4 Solar Connectors
NEW Solar Panel
MC4 Connector ASSEMBLY
is about removing all splice cables made by fake installers from solar panels to avoid fire eating up your house sooner or later.

MC4 is the name of the connection type on all new solar panels, providing an IP67 waterproof and dust proof safe electrical connection. MC4 will not connect with older MC3 type connectors.
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.
Great, but how do you get the power from the panel on an outbuilding roof to your controller 20 Metres away ?
You can buy pre cut leads from 2 Metres to 10 Metres, We sell these, but a more efficient way is to buy the cable which you can cut to the exact length you need and then attach MC4 connectors.
We offer a custom cut length cable with MC4 connectors fitted service, if you do not feel confident enough to tackle this yourself.
The picture above shows all the parts for the male and female connectors.
All you need is the cable, a male and female MC4 connector, wire strippers, some wire crimps and about 10 minutes of your time.








We would advise you to test the continuity of your cable with the new MC4 connectors on before connecting to your solar panels or charge controller.
This will confirm you have a good connection that will last for years.
Please remember never
disconnect the connectors when the sun is on your solar panels or they are connected to a battery, you may be injured by your free green electricity.
Stay safe and thank you for looking at our MC4 connection guide
