FAQS 4
Why do Huawei inverters have arc detection?
If PV modules or cables are incorrectly connected or damaged, electric arcs may be generated, which may cause fire. Huawei inverters provide arc detection to ensure the safety of users' lives and property. This function is enabled by default.
Do Huawei inverters meet UL 1699b-2018 arc fault circuit protection requirements?
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."
Which inverter does Huawei use for AFCI?
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.
How do I disable AFCI test on Huawei inverters?
Huawei inverters provide arc detection to ensure the safety of users' lives and property. This function is enabled by default. To disable this function, go to the Device commissioning screen from the FusionSolar app, choose Settings > Feature parameters, and disable AFCI test.
