Photovoltaic energy connector is also called MC connector. In photovoltaic systems, Photovoltaic energy connector accounts for a small proportion, but it needs to be used in many links, such as junction boxes, combiner boxes, cable connections between components and inverters. Many construction workers do not know enough about the photovoltaic energy connector, and there are many power station failures caused by the problem of the photovoltaic energy connector.

In addition to the quality of the connector itself, another very important reason for the burning of the Photovoltaic energy connector is that the construction was not done properly, which caused the virtual connection of the connector, which caused the DC side to draw arc, and then caused a fire. Problems caused by the Photovoltaic energy connector include: increased contact resistance, heat generation of the connector, shortened service life, burnout of the connector, power failure of the string, failure of the junction box, leakage of components, etc., which cause the system to fail to work normally and affect the power generation efficiency. .

Therefore, the Photovoltaic energy connector is a very important component of the photovoltaic system. It should attract enough attention. In the process of product selection and construction, the following points should be paid attention to:

1. Use domestic and international famous brand Photovoltaic energy connector products with reliable quality,

2. Photovoltaic energy connector products of different manufacturers cannot be mixed together, and the products may not match.

3. Use professional wire stripping pliers and crimping pliers. Unprofessional tools cause poor crimping. For example, part of the copper wire is cut, some of the copper wire is not crimped in, and is crimped to the insulating layer by mistake, and the crimping force is too small or too large.

4. After the Photovoltaic energy connector and the cable are connected, check it. Under normal circumstances, the resistance is zero, and it will not break if you pull it hard with both hands.
