2.Solax’s solution In order to prevent the arcing of the DC side of the inverter from causing fires and other hazards, SolaX engineers have developed the integrated AFCI function, which detects the arcing of the DC side and cuts the circuit in time to protect the user and the electrical system.
DC arc-fault circuit protection provides supplementary protection against fires that may arise as a result of arcing faults in PV system components or wiring. SMA Sunny Boy US inverters are now available with integrated Arc Fault Circuit Interrupter (AFCI) functionality.
These rules mandate that all solar inverters operating at any DC voltage higher than 120 V have to include AFCI protection to prevent fires caused by arc faults. Solar inverters without AFCIs were still allowed until the end of 2024, but from 2025 onwards, compliance is mandatory for certification and safety inspections.
Fires at traditional PV stations cannot be directly put out with water because of the high DC voltage, so installing PV inverters that are equipped with the arc fault detection function is a must. What is an AFCI circuit breaker and how does it work?
Our BESS energy storage systems and photovoltaic foldable container solutions are engineered for reliability, safety, and efficient deployment. All systems include comprehensive monitoring and control systems with remote management capabilities.
