What is a MC4 Connector? 

MC4 Connectors are a small but important component of solar installation.  

There a re many benefits of genuine MC4 connectors, however with so many cheap copies available in the marketplace today, it is crucial that only original MC4 connectors are used to reduce the risk of overheating which could lead to a fire.

For those who like to get technical, MC4 stands for the manufacturer Multi-Contact and size (4mm2) of the contact assembly pin.  MC4 Connectors are single-contact electrical connectors commonly used for connecting solar panels.  MC4s allow strings of panels to be constructed through pushing the connectors from adjacent panels together.  MC4 Connectors have been used to equip almost all solar panels produced since about 2011.

Why should only Genuine MC4 Connectors be used?

While from the outside it can be difficult to distinguish a genuine MC4 connector from a copy, the technical comparisons differ greatly.  Serious deficiencies in such copies can result in damage during installation or may even lead to fire.

Furthermore, the use of copies instead of genuine MC4 connectors may result in the following:

Using different brands can cause the mis-mating of connections, resulting in poor connections. This can cause a rise in temperature, which could result in overheating the system, or could allow water to enter, possibly resulting in a fire.

Someone could be electrocuted when touching the connector where poor connections allow rain and dust to enter, reducing the insulating properties of the connector.

System failure is more likely to occur and a fire could lead to the loss of a home or someone's life.

Re-work will need to be undertaken if the system is working incorrectly.

Copies have not undergone the same stringent testing that genuine MC4 connectors have. Multi-Contact has been a part of the industry for more than 10 years and has thoroughly researched and tested the behavior of their connectors over a long period of time.
