To verify the performance and availability of arc-fault circuit interrupter (AFCI), Huawei entrusted the China General Certification Center (CGC) to complete comprehensive evaluation, with its results showing that Huawei inverters with the AFCI function meet the requirements of UL 1699B-2018 "Safety Standard for PV DC Arc Fault Circuit Protection."
Huawei inverters with the AFCI function have been successfully applied in many countries and regions, such as China, North America, Europe, Asia Pacific, Latin America, Southeast Asia, the Middle East, and Africa. Complies with the UL 1699B-2018 standard and reaches the L4 level in CGC/GF 175:2020.
This algorithm enables accurate detection of electric arc faults, allowing for swift protection by shutting off the inverter within 0.5 seconds. With this advanced approach, Huawei ensures efficient arc detection and timely mitigation of potential hazards.
However, Huawei has successfully developed an intelligent, precise, and rapid solution by leveraging a neural network algorithm. This algorithm enables accurate detection of electric arc faults, allowing for swift protection by shutting off the inverter within 0.5 seconds.
By combining these elements, Huawei’s intelligent arc detection solution offers enhanced capabilities for accurate and efficient arc detection. Furthermore, the “AI BOOST AFCI” model has undergone significant enhancements to enable effective identification of arc characteristics across various scenarios.
Recognizing this need, Huawei has introduced inverters equipped with DC arc detection (AFCI) functionality specifically designed for distributed photovoltaic systems, including residential installations. These advanced features aim to mitigate the risk of electrical fires and elevate the overall safety and performance of PV system
