TEAL Electronics, a San Diego-based subsidiary of SL Industries Inc., has introduced the TEALsolar configurable combiner box for commercial- and utility-scale solar photovoltaic systems.
The combiner box is available in eight-string, 12-string, 16-string, 20-string, 28-string and 36-string systems. Standard configurations include a DC disconnect and transient voltage surge suppression (TVSS) device integrated into the unit. Both devices can be optionally removed.
Fuses also come standard and are available up to 30 A per string in the eight-string and 12-string units, 25 A in the 16-string unit, 20 A in the 20-string unit, 15 A in the 28-string unit, and 10 A in the 36-string unit.
Enclosure options available are NEMA 3R, 4 or 4X enclosures in painted steel, nonmetallic fiberglass and stainless steel. The TEALsolar combiner box provides more internal working space than most products, enabling easier installation and wiring of the units in the field, according to the company.
