An arc fault confirmation method, an apparatus, and a medium, related to the technical field of power electronics. Compared to the prior art, where an inverter issues an alarm immediately after an arc detection apparatus detects an arc fault signal, leading to the possibility of false alarms, the present technical solution, after an arc detection apparatus detects an arc fault signal, first reduces the power generation on the alternating current side to eliminate any possible arcs and avoid damage to a photovoltaic system caused by real existing arcs. Then, it is determined whether there are any strings with voltage changes that meet preset conditions before and after the power generation is reduced on the AC side; if such strings exist, shut down and issue an alarm. By adopting the present technical solution, after receiving an arc fault signal, an arc extinguishing process is first carried out. Then, based on the voltage changes of each string before and after the arc extinguishing process, it is confirmed whether an arc actually exists. This secondary confirmation method can effectively reduce the occurrence of false arc alarms.
