AFCI Combiner Box

ETEK Solar AFCI PV Combiner Boxes integrate Arc Fault Circuit Interrupter (AFCI) technology to help detect and interrupt potentially dangerous DC arc faults in solar photovoltaic systems. Arc faults can occur because of damaged cables, loose connections, aging components, or installation defects, creating a serious fire risk in PV installations.

By combining PV string aggregation, conventional circuit protection, surge protection, and arc fault protection, AFCI combiner boxes provide an advanced solar safety solution. They are particularly suitable for commercial rooftops, public buildings, warehouses, industrial facilities, and projects with enhanced fire-safety requirements.
