What causes arcs on PV inverters?

Arcs can occur on both dc and ac side of PV inverters. A disconnection of a cable, for example, may cause a dc arc when high current is flowing. Compounding this problem is the fact that the PV array will supply current continuously while irradiance is occurring on the solar cell. This can lead to continuous arcing and lead to fires.
