The commonly used solar connector is MC4 (PO or PPO insulation). The male and female heads are composed of a male core, a female core, a male head, and a female head. The male core corresponds to the female head, and the female core corresponds to the male head. Half of the corresponding wire size is 2.5-6 square.

MC4 male and female plug production steps

The first step is to check the male core, female core, male head, female head, and fasteners for damage.

The second step is to strip the insulation length of the photovoltaic cable (about 1cm) with a wire stripper according to the length of the crimping end of the male core (or female core). Use a wire stripper to strip the 4mm solar cable to avoid damage to the core.

The third step is to insert the core of the cable into the crimping end of the male core (female core), and then press it with crimping pliers, and then try to pull it out with appropriate strength. Whether the connector can be durable for a long time has a certain relationship. If it is loose and falls off, it will lead to poor release in the later stage, resulting in a DC arc, and a certain safety hazard to the entire power station and building. (Be careful not to press the male core (female core) when crimping. Position of the card head).

The fourth step is to put the fastening end of the female (male) head into the cable first, and then clamp the male core (female core) into the female head (male). When it clicks, you will hear sound. Try again with an appropriate strength, and it is advisable not to separate.
