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."

Where are Huawei AFCI inverters used?

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. Complies with the UL 1699B-2018 standard.

How big is PV in China?

According to the China Photovoltaic Industry Association, the total installed capacity of residential PV in China reached 10.1 GW at the end of 2019, covering over 1.08 million homes, more than 50 times that in 2015. Figure 1-2 shows distributed PV applications and system types.

Do I need a smart PV LTE wireless network?

Note: Smart PV LTE Wireless Network deployed in the plants is required for remote experts diagnosis and maintenance APP.

How to prevent electrical fires in distributed PV systems?

However, electrical fires — mainly caused by DC arcing — are the primary risk that needs to be prevented for distributed PV systems. Therefore, it is essential that comprehensive measures are employed, especially intelligent arc detection and rapid shutdown technologies, in order to improve the safety and control level of PV plants.

What is a distributed PV system?

In addition, in distributed PV, the mainstream deployment method involves deploying PV modules on various buildings, including building applied photovoltaics (BAPV) and building integrated photovoltaics (BIPV). As such, electrical safety is the focus of accident prevention for this type of power generation form.
