Low Cost Arc Fault Detection and Protection for PV Systems, Januaru 30, 2012-September 30, 1913.

摘要

Due to fire hazard safety concerns, the National Electrical Code requires arc-fault protection for the dc wiring associated with solar photovoltaic (PV) systems. In order to meet the $1/watt goal of the DOE SunShot Initiative, arc fault protection must be provided within the context of $0.40/watt balance of system and $0.10/watt power electronics costs. A highly integrated arc fault detector and circuit interrupter is the best solution to address the safety needs of the industry while still allowing the lowest possible levelized cost of energy (LCOE) for both new installations and retrofit applications.
