PV Connectors: The 'Bridge' of Solar Systems—How Much Do You Know?

In solar photovoltaic systems, PV connectors play a vital role.  They are not only the "bridge" for power transmission but also directly impact the safety and efficiency of the system.  So, what exactly are PV connectors?  What types are there?  How to choose the right product?  This article will answer these questions one by one.

1.  What Is the Purpose of a PV Connector?

PV connectors are used to connect photovoltaic modules, inverters, cables, and other equipment to ensure efficient power transmission.  They also need to be waterproof, dustproof, and weather-resistant to adapt to outdoor environments.  Whether it's a small rooftop PV system for homes or a large-scale solar power plant, connectors are indispensable components.

2.  What Types of PV Connectors Are There?

There are many types of PV connectors.  Here are some common ones:

（1.）MC4 Connectors: The most widely used type, known for high reliability and ease of installation.

（2.）MC4-T Series: Suitable for various PV systems, with stable performance.

（3.）MC4-Y Series: Used for branch connections, facilitating system expansion.

（4.）FUSE Series: Equipped with built-in fuses for additional protection.

（5.）Diode Series: Integrated with diodes to prevent reverse current.

At CNLonQcom, we offer a wide range of PV connectors with diverse types and styles to meet the needs of different customers.

3.  How to Choose the Right PV Connector?

Choosing the right PV connector is key to ensuring the safe operation of the system.  Here are some important selection criteria:

（1.）Compatibility: Ensure the connector is compatible with the modules and cables.

（2.）Rated Current and Voltage: Select based on the current and voltage requirements of your PV system.

（3.）Waterproof Rating: Choose products with an IP67 waterproof rating to adapt to outdoor environments.

（4.）Brand and Quality: Opt for reputable brands to ensure reliability.
