Case Studies
Several incidents highlight the importance of DC arc detection:
- Australia (2009–2011): Over 250 fires were caused by DC arc faults in PV systems, emphasizing the need for effective detection (AC Solar Warehouse).
- Bakersfield, CA (2009): A PV system fire was linked to an undetected DC arc, causing significant property damage (ResearchGate).
- Mount Holly, NC (2011): Another fire incident underscored the limitations of early detection methods, prompting improvements in standards like UL 1699B.
