Understanding the Role of DC Arc Fault Circuit Interrupters (AFCI) in
DC AFCIs detect dangerous electrical arcs and disconnect the circuit before any damage occurs. This is vital for solar installations, where high-voltage DC systems are prone to sustaining arcs longer than AC circuits. By

What is AFCI and why does it matter to your solar PV system?
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.
