AFCI (Arc Fault Circuit Interrupter) and RSD (Rapid Shutdown Device) are indispensable for PV system safety, addressing arc fire risks and emergency shutdown needs—critical for operators and purchasers. As global PV installations grow in power and density, these technologies have shifted from “optional” to essential, especially in emerging markets like Brazil, matching local grid instability and extreme weather.
Widespread adoption requires three key efforts: 1) Policy drive—Brazil can learn from U.S. NEC 2017 standards, integrating AFCI+RSD into grid-connection rules. 2) Cost optimization—scale production and tech iteration to lower module costs, emphasizing “safety investment = long-term risk mitigation.” 3) Industry collaboration—inverters makers partner with stakeholders to launch customized models (e.g., for Brazil’s telecom/mining) and boost user awareness via training.
With joint efforts, AFCI+RSD will soon become universal across PV systems globally, safeguarding the industry’s sustainable development.
