Updates to Certification Standards for DC solar Connectors

Updates to Certification Standards for DC solar Connectors

Ulrika Frank, President of the International Organization for Standardization (ISO), said in her 2022 New Year's message, "Standards are clearly an important tool for solving many problems. From government to business to civil society, standards enable people around the world to Speak a common language and become an international benchmark for quality, safety and most importantly trust".

The first connector standard in the photovoltaic industry was 2PfG 1161 launched by TÜV Rheinland in 2004. With the continuous innovation of connector products and the development of market demand, it has mainly gone through DIN V VDE V 0126-3 (2006), EN 50521 ( 2008) and EN 50521:2008+A1 (2012), culminating in IEC 62852 in 2014. Currently, the industry-applicable standard is IEC 62852:2014+A1 (2020). International standards bring norms to the industry and ensure the safety and reliability of products in terminal applications.

In addition to international standards, various countries or regions also have locally recognized industry standards, such as UL 6703 in North America, JET in Japan, and "GB/T 33765-2017 DC Connectors for Ground Photovoltaic Systems" in China.
