# **Using Arc-Flash Relays to Maximize PV Equipment Protection and Uptime**

The size of photovoltaic (PV) systems is growing beyond 2- and 3-gigawatts, and they are requiring more solar modules, combiner boxes, and inverters. When these systems expand to this level of power capability, the number of cable/wiring connections (and failure points) increases substantially.

Our technical paper, ***Arc-Flash Relays - A Valuable Detection Solution for Photovoltaic Systems****,*validates using arc-flash relays for large-scale installations in addition to using overcurrent protection for maximum equipment protection, mitigation of incident energy levels, and reaction to arcs before they cause irreparable damage.
