OutBack PV Ground-Fault Detection and Interruption System
Ground fault detection and interruption is required by US National Electric Code for PV
arrays mounted on or within a specied vicinity of residential dwelling roofs as a safety
precaution. The OutBack PV Ground-Fault Detection and Interruption System protects
wiring and system components for one, two or four PV arrays when used in a GSLC, FLEXware 250, FLEXware 500 or FLEXware 1000.
