Electrical protections should be used in photovoltaic systems to prevent property and personal damage. The main ones are protection against indirect lightning strikes and against arc flash. The surge protection device (SPD) will be presented with their physical and electrical characteristics, selection/sizing, and the installation mode in combiner boxes and electrical panels, according to technical standards and best engineering practices considering the inductive and temperature effects. The arc fault detector and circuit interrupter (AFCI) will also be addressed, which prevents against fire in the systems and must be included in the inverter as determined by INMETRO regulation.

Audience: Engineers, investors, technicians and installers
