Principle of arc protection for solar inverters
When a PV inverter with an integrated arc-fault circuit interrupter (AFCI) is used, a serial electric arc in the PV array is detected soon enough and extinguished by an interruption of the current.

Photovoltaic panel arc frequency
Most PV DC arc faults are series arcs across a high-resistance gap. Series arcs often show wideband current noise, typically concentrated between 1 kHz and 100 kHz, superimposed on the DC string current.
