The MC4 Solar Panel Connectors are the most recommended to ensure a good connection between the connectors.

MC4 Connectors Solar Panels

The set of MC4 Solar Panel Connectors is essential to be able to make a safe and watertight connection of the photovoltaic modules. It consists of a pair of connectors, an MC4 Male connector and another MC4 Female connector, that fit perfectly with the connectors that are already included in the panel.

It is a very standardized type of connector, since the vast majority of manufacturers use this type of connector, so compatibility is maximum. In order to properly connect a photovoltaic panel to a solar system, the use of this type of connector is always recommended.

The MC4 Solar Panel Connectors are served in pairs, and also incorporate a metal rod on which the cable that will come out of said connector is crimped. Make sure to use the appropriate color code in the wiring, since you do not always have to pay attention to the sign printed on the MC4 connector itself.

Each stem is also different, so make sure, before crimping it to the cable, that it is the desired color so that later the connection corresponds to the terminal you want to connect.

From the photovoltaic modules themselves, a couple of MC4 Solar Panel Connectors come out, identified as positive for the male connector and negative for the female connector. That is why, when we make a connection with another pair of connectors, we must take into account that the one with the opposite sign will fit.

To properly crimp the cable to the connector stem, we must use a 6 mm section cable, stripping a length equivalent to approximately 1 cm. The thread that secures the end of the cable will be separated and left on the fragment of the cable. We will use a cable crimping tool, which secures the metal to the cable with enough pressure so that it is very firm.

Once secured, we will introduce the metal stem inside the corresponding plastic body. We will hear a slight click that will indicate that it is secured, and finally we will screw the end onto the plastic body so that it is well secured.
