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''s AFCI solution is represented by the SUN2000 series inverter, which mainly adopts AFCI integrated with inverter technology and does not need to install additional AFD and AFI devices, as shown in Figure 2.8.
The testing procedure will follow the UL 1699B standard, which specifies the requirements for DC arc protection compliance in PV DC sources. However, the study is limited to evaluating the DC arc fault protection feature in the Huawei Solar Inverter SUN2000-2KTL-L1 only.
DC series arc fault with AFCI enabled test. The insulation resistance (RISO) monitoring function test was conducted to ensure that the Huawei Solar Inverter SUN2000-2KTL-L1 is capable of measuring the insulation resistance of the PV system before allowing the DC circuit to be completed and start generating power.
Our standardized solar power and energy storage products are engineered for reliability, safety, and efficient deployment. All systems include comprehensive monitoring and control systems with remote management capabilities.
