With the rapid development of the distributed, especially household photovoltaic market in recent years, the quality of the system has become more and more prominent. A fire in a photovoltaic system will not only have a negative impact on the industry, but also involve personal safety. According to a foreign research report, connector mutual insertion and irregular connector installation ranked the first and third causes of fire.

      In a photovoltaic power generation system, photovoltaic connectors are mainly used in components, combiner boxes, inverters and the connections between them, most of which are installed in the factory, and the crimping quality is relatively reliable. About 10% of the remaining connectors need to be manually installed at the project site, mainly referring to the need to install connectors at both ends of the photovoltaic cable connecting each device. According to the experience of many years of customer visits, due to the lack of training of on-site installation workers and the use of professional crimping tools, crimping irregularities are widespread.

      Connectors are small parts, but they will affect the operational efficiency of photovoltaic projects. Compromise with quality usually means high subsequent losses and risks, which could have been avoided.

      For the installation of photovoltaic connectors, the crimping link is the most important, and it is recommended to use professional crimping tools. For engineering installers, crimping training is an indispensable link.
