Recently in Shanghai, A model of junction box with rated current 30A from Zhejiang Twinsel Electronic Technology Co., Ltd. (hereafter referred to as “Twinsel Electronic”) has successfully passed the test from the global leading third-party testing Institute-TUV-SUD and achieved the certificate from TUV-SUD. It is the first enterprise that has been awarded the certificate of 30A PV junction box by TUV-SUD. The acquisition of the certificate means that that Twinsel Electronic ‘s 30A junction box conforms to the IEC62790 standard, further enriches Twinsel Electronic’s large current product series, satisfy the demand of higher power PV modules and further improves Twinsel Electronic’s market competitiveness.

    Zhang Zhulin, the OD and First COV of TUV-SUD Smart Energy said: As the increasing pressure of saving cost and improving efficiency on the PV Power Plants, various high efficiency and large-size silicon modules come out, which forces the junction box to improve current carrying capacity. For this model of junction box certificate project of Twinsel Electronic, TUV-SUD has made a comprehensive performance testing and evaluation test in accordance with IEC62790. We are very glad to see that it has successfully passed the TUV-SUD certificate testing, which is the double recognition of the performance and reliability of this junction box of Twinsel Electronic.

   Twinsel Electronic has always been moving forward step by step, upgrading from 20A to 25A, and then to 30A at present. While meeting the 30A current carrying capacity, ensuring the safety and reliability of the product for long term outdoor use. Thanks very much to TUV-SUD project professors’ comprehensive technical support, Twinsel Electronic become the first enterprise that has passed the 30A junction box certificate test of TUV-SUD. It has two meanings for us. First, it can provide more efficient, fast and high quality services for customers, and satisfy the professional technical support to 500W+ modules of photovoltaic enterprises, second, Twinsel Electronic’s detection technology from software, hardware to team configuration has reached the industry leading level. “Twinsel Electronic’s product advantages are obvious, which further proves the high quality of our 30A Current Junction Box and greatly improves the competitiveness in the domestic and foreign markets. Look forward to further strengthening technical exchanges with TUV-SUD, benefiting from more cooperation and jointly promoting the development of the industry!” Said Zeng Xue Ren, CEO of Twinsel Electronic.
