Technical FAQs 4

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.

Does Huawei solar inverter sun2000-2ktl-l1 have DC arc protection?

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.

Does Huawei solar inverter sun2000-2ktl-l1 have AFCI enabled test?

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.
