Information

Photovoltaic energy connector, also known as MC connector. In photovoltaic systems, connectors account for a small proportion, but they are required in many links, such as junction boxes, combiner boxes, and cable connections between components and inverters.

Photovoltaic energy connector
In addition to the quality of the connector itself, another very important reason for the burnout of the photovoltaic connector is that the construction was not done well, which resulted in a virtual connection of the connector, which caused the DC side arc, which in turn caused a fire. The problems caused by connectors include: increased contact resistance, connector heating, shortened life, connector burnout, string power failure, junction box failure, component leakage, etc., which cause the system to fail to work properly and affect power generation efficiency.
In the entire photovoltaic system, the DC side voltage is usually as high as 600-1000V. Once the photovoltaic module joint contacts are loose and the contact is poor, it is very easy to cause DC arcing. The DC arc drawing will cause the temperature of the contact part to rise sharply, and the continuous arc will generate a high temperature of 1000-3000 ° C, accompanied by high temperature carbonization of the surrounding devices. In the lighter case, the fuse and cables will be blown, and in the severe case, the equipment will be burnt and cause a fire.
