What are the PV cable connector models?

PV connectors are important components used to connect solar PV modules to each other, between PV modules and inverters, and between other solar system components. Because of the different sizes of linked solar cable, there are many different models and sizes of PV cable connectors, and choosing the right model depends on your specific needs, the design of your solar system, and the PV modules used. Below are some common PV cable connector models:

  1. MC4 connector: MC4 is a very common solar cable connector, divided into MC4 male and MC4 female, suitable for most solar PV module connections.MC4 connectors are waterproof, dustproof and highly weatherproof.

  2. MC3 connectors: MC3 connectors are similar to MC4, but still have some use in some regions or specific applications.

  3. Amphenol connectors: Amphenol also offers a range of solar cable connectors for different types of solar systems.

  4. Tyco Connectors: Tyco (now TE Connectivity) also produces solar cable connectors, available in a number of different models for a variety of solar applications.

  5. Hirose Connectors: Hirose is another company that offers solar connector solutions, and their connectors are also common in certain markets.

  6. Amphenol Helios H4 Connectors: This is a hot model from Amphenol that is widely used in large-scale solar systems.

  7. Multi-Contact Connectors: Multi-Contact is a company that offers a wide range of PV connectors, and their connectors are also common in certain markets.

  8. Souriau Connectors: Souriau (now Esterline Connection Technologies) offers a number of specially designed solar connectors.


Please note that these are only some common PV cable connector models and there are many other manufacturers and models available on the market. When selecting a connector, you should consider the electrical requirements of your system, environmental conditions, manufacturer's recommendations, and compliance with local standards and regulations. It is best practice to consult with your solar system designer or supplier to ensure that the right connector model is selected.
