For large scale ground mount utility PV systems, the challenges of providing the correct type and level of system protection becomes ever more critical as system voltages and operating currents are typically significantly higher. Spread out over large areas, with export powers typically in the magnitude of 10’s of MW these large-scale solar farms represent significant financial investments for the owners and operators. For this reason, it is critical to ensure safe and reliable operation of the DC, LV and MV circuits within these systems as well as meeting local and national codes for connection to the grid.
