1500V DC Combiner Box 12 In 1 Out

The 1500V DC Combiner Box 12 In 1 Out, supplied by China manufacturer Zhejiang Soutya New Energy LLC, is a 1500 V DC PV combiner housed in an IP66-rated aluminum alloy enclosure for high durability and reliable outdoor service.

Inside it mounts 12 DC fuse holders, 1 main DC MCCB, 2 DC surge protective devices, 1 current-measurement unit, 1 positive/negative busbar system and output terminals, providing integrated over-current, isolation, surge, grounding and optional leakage protection for large-scale photovoltaic plants.

Application scenarios

1.Utility-scale ground-mounted PV plants

Deployed between strings and central inverters, the box consolidates up to 12 input strings, reduces cable home-runs, and delivers fused, surge-protected, and MCCB-isolated DC output to the inverter room.

2.Large commercial & industrial rooftop systems

On wide factory roofs the unit collects multiple string runs into a single harness, minimizing rooftop penetrations and providing local isolation for maintenance without shutting down the whole array.

3.1500 V DC agrivoltaic / fish-PV installations

IP66 aluminum housing and surge protection guard against humidity, dust, and field-generated transients, while the resettable MCCB allows safe lock-out during farming operations or cleaning cycles.

4.Desert and high-irradiation solar parks

Designed for –40 °C to +60 °C, the enclosure resists sand and UV; the current-measurement unit feeds data to SCADA for real-time string-level fault location in expansive desert arrays.

5.Pre-fabricated skid or tracker DC hubs

The compact 12-to-1 design is bolted directly onto tracker piers or skids, cutting BOM and labor costs while meeting the latest IEC 60269-6 and IEC 61439-2 requirements for 1500 V DC PV assemblies.
