HO CHI MINH CITY, Vietnam, Aug. 28, 2024 /PRNewswire/ -- The DC arcing remains a significant concern in the PV industry, often being the primary catalyst for fires. As solar installations increase in scale and longevity, the risks tied to DC arcing have risen, necessitating advances in detection and mitigation technologies.
In August 2024, Sungrow partnered with XB Solar, a renowned clean energy service provider in Vietnam, to conduct functional tests of its latest AFCI 3.0 technology in Tay Ninh Province, Vietnam. AFCI 3.0 demonstrated exceptional performance, surpassing industry standards with its advanced arc detection range and rapid arc extinction capabilities.
Sungrow's AFCI 3.0 Ensures Safety in Large-Scale C&I Power Plants
The tests were conducted in full compliance with the latest international standard, IEC 63027. Using an automatic spherical arc simulator and Tektronix oscilloscope, the results were precise and reliable. During the tests, AFCI 3.0 technology, based on a new generation AI computing system, achieved precise detection and rapid interruption of DC arcing in various conditions. For instance, with a 450-meter DC cable loop, AFCI 3.0 technology detected and interrupted the arc within 1.2 seconds. Under a 650-meter DC cable loop, AFCI 3.0 technology stopped the arc within 1.5 seconds, far exceeding the requirements of the IEC 63027 standard.
R&D Team Testing AFCI 3.0 at a C&I Power Plant in Tay Ninh Province, Vietnam
AFCI 3.0 technology is now fully integrated into Sungrow's SG150CX, the new generation high-power string inverter. With its wide detection range and rapid arc extinguishing capability, AFCI 3.0 empowers the seamless design and deployment of expansive, efficient, and secure PV subsystems, strengthening safety in large-scale commercial and industrial (C&I) solar projects. Looking ahead, Sungrow remains at the forefront of innovation, driving performance advancements to ensure the highest level of safety for the global PV industry.
*Note: The tested module in this evaluation is identified as the Q.PLUS DUO L-G5.2 365, boasting a nominal power of 365W, a maximum current of 9.41A, and a peak voltage of 38.79V at maximum power.
