In a photovoltaic power station, to gather the power of a large number of components together and enter the inverter, it must rely on cables and connectors. The photovoltaic connector is one of the components, combiner boxes, controllers, and inverters in the photovoltaic power generation system.

The development of photovoltaic connectors requires continuous advancement in technology. Only in this way can we adapt to the needs of the market and be in a leading position among the peers. The production of photovoltaic connectors is not a simple technology, it is more complicated. It must have

1.3 Photovoltaic connector failure

Photovoltaic connectors account for less than 0.5% of the initial investment cost of the system, but they are a key component of the photovoltaic system. It ensures that the power generated by the system can be stably transmitted from the components to the inverter and the user side. The EU Horizon 2020 "Solar Bankability" project team gave a list of TOP20 technical failures in the operation and maintenance of power stations based on the on-site operation and maintenance data of 746 power stations. "Burn" is ranked 2nd in the failure list.

According to the international standard EN50521 for photovoltaic connectors, the contact resistance must be less than or equal to 5mΩ.

Photovoltaic connectors are one of the key components in the photovoltaic industry chain to achieve "turning light into electricity". They are used in all links of the photovoltaic industry chain, such as junction boxes, combiner boxes, inverters, and so on. With the development of the photovoltaic industry, the market volume of photovoltaic connectors is increasing day by day, but there are only a handful of domestic companies producing photovoltaic connectors. Facing the contradiction between the market demand for photovoltaic connectors and the supply of products, how should domestic connector companies seize the opportunity to innovate and develop? To this end, the reporter of "International Cable and Connection" interviewed Wenzhou Xinhui Photovoltaic Technology Co., Ltd.
