Applications
Solar PV combiner boxes bring together multiple solar array strings into a single output feed, protecting each string with its own overcurrent device before the combined DC output runs to the inverter. The Stahlin J1614HW is used in residential, commercial, and light industrial photovoltaic installations where a weather-resistant, corrosion-proof enclosure is required — the NEMA 4X fiberglass construction makes it well suited for rooftop, ground-mount, and outdoor pad-mount applications exposed to rain, humidity, and UV. The Ferraz Shawmut ULTRASAFE USM1 holders accept standard cylindrical solar fuses, providing per-string overcurrent protection and a safe fuse-pull mechanism for maintenance without live exposure. This type of combiner box is standard balance-of-system (BOS) hardware in PV arrays of all sizes and remains in active use across the solar industry today.
This Stahlin J1614HW NEMA 4X Solar Combiner Box is new and unused. It may be out of its original packaging. The enclosure and all internal components — including the 11 Ferraz Shawmut ULTRASAFE USM1 30A breaker holders, DIN rail, and grounding bus bar — show no signs of use or wear.
