Sungrow Receives the World’s First DC Arc Detection and Interruption Technical Report


HEFEI, China – Sungrow has announced that it received the world’s first DC arc detection and interruption technical report issued by TUV SUD. The report outlines Sungrow SG110CX has been tested according to the newly recognized international standard IEC 63027 ED1 (draft), 82/1636/CDV, underlining the global leading position on product reliability and safety.

The arc fault is an unintended arc created by current flowing through an unplanned path. Conventional overcurrent protective devices do not detect low level hazardous arcing currents that have the potential to initiate electrical fires. Sungrow SG110CX integrates the AFCI function, which utilizes advanced electronic technology to “sense” the different arcing conditions to help reduce the electrical system from being an ignition source of a fire. Optimized for commercial and industrial PV plants, the featured product SG110CX tested to be more reliable and securer embraces a shipment of over 5 GW all over the world.

“We are happy to provide Sungrow with this type of technical report which gives Sungrow an internationally recognized proof that its SG110CX was developed to rigorous safety standards, preventing the loss from an arc fault,” said Mr. Hurry Xu, Vice President of TUV SUD China New Energy Vehicle Testing Laboratory, an international trusted partner focused on testing, certification, inspection and training. “Our community of experts is passionate about advanced technology and delighted to contributes to a more sustainable future with partners like Sungrow,” he added.

“We are very proud of becoming the world’s first company receiving the remarkable technical report,” said James Wu, Vice President of Sungrow. “Product safety and compliance are paramount for the success of Sungrow and our customers likewise. Third-party independent verification with regards to all applicable technical standards is required in the marketplace and we have taken the necessary steps accordingly.”

Sungrow reported that the first batch of SG110CX enabled with AFCI function has been delivered to Southeast Asia, and more deployments are expected to come in the following months. The Company also mentioned that a wider range of its products will get certified with AFCI in the near future.
