If PV modules, cables or DC connectors are incorrectly installed or damaged, arcs can occur which can then lead to dangerous fires. In the DC grid, arcs do not usually extinguish themselves due to the lack of zero crossing of the voltage. This, in turn, can lead to a significant fire risk.
For this reason, Huawei's inverters have built-in arc detection, which provides customers with an increased level of safety. This feature is enabled by default, but can be disabled via app if desired.
Equipped with the latest AI technology, arc detection (AFCI) makes safe arc detection even faster, providing the highest level of safety. Arc detection works both with and without optimizers on units equipped with it. In addition, with the option of full optimization, pinpoint arc detection can reduce troubleshooting time by 80%.
