The world's first "National product optimization" test certificate for differentiated application weather resistance of junction boxes based on IEC 63556 full application scenarios

With the development of the whole industrial chain of China's photovoltaic industry, the environmental applicability of photovoltaic products has also made a great breakthrough, aquatic photovoltaic has been applied in lakes, reservoirs and other scenarios, in terms of power generation, safety and other aspects have been recognized by the industry, at present, for the photovoltaic technology in the inshore environment continues to break through, China has begun to take the conditions for the large-scale development of offshore photovoltaic projects. The emerging inshore photovoltaic application environment has brought new threats and challenges to photovoltaic modules, such as storms, waves, sea ice, guano, high salt spray, and high humid heat environment. Higher requirements are put forward for the waterproof sealing, corrosion resistance and mechanical properties of the device. In particular, higher requirements are put forward for the performance of Junction Boxes, connectors and the overall adaptability of components.

The new connector uses a double or even triple sealing structure to ensure a good sealing effect even in harsh sea conditions. At the same time, the connector is configured with anti-corrosion measures suitable for the Marine environment, optimizing the connector design, simplifying the offshore installation process, reducing the difficulty of maintenance, and improving the overall operation and maintenance efficiency.

On June 13, 2024, in SNEC Shanghai photovoltaic exhibition, CPVT National Photovoltaic Quality Inspection Center awarded Suzhou Qc Solar with differentiated application weather resistance "National product optimization" test certificate (deep blue ocean series), and connector differentiated application weather resistance "National product optimization" test certificate (deep blue ocean series). The certificate is based on the IEC 63556 all-application scenario certification, which fully demonstrates the professionalism of Suzhou QC Solar in the field of photovoltaic and the unremitting pursuit of product quality.
