AC Combiner Box 6 In 1 Out

The AC Combiner Box 6 In 1 Out, supplied by China manufacturer Zhejiang Soutya New Energy LLC, is a 400 V–690 V three-phase inverter-combiner unit constructed with a powder-coated, UV-resistant steel enclosure and IP65 / IK10-rated sealing for durable outdoor performance. The enclosure houses six 4-pole MCBs (up to 100 A each) that deliver individual over-current and short-circuit protection to each inverter input, while a single 4-pole MCCB (400 A / 630 A selectable) provides visible-break isolation and overload protection for the combined output. Factory-wired L1, L2, L3, N and PE copper busbars ensure dependable current-carrying capacity and equipotential bonding, and a built-in Type-2 4-pole AC SPD guards against lightning-induced surges. Engineered for up to six solar string inverters (6 × 50–100 kW), it provides essential AC combining, surge immunity and maintenance safety.

Application scenarios

1. Medium-Scale Commercial Rooftops (300–600 kW)

The six 100 A MCB inputs accept up to six 100 kW string inverters; the 630 A MCCB output feeds the main switchboard, giving a single lockable isolation point for maintenance teams on large factory or office roofs.

2. Car-Port & Canopy Arrays

Its shallow, IP65 wall-mount cabinet bolts to steel beams, providing parking shelters with a weather-proof hub where six inverter outputs are combined, surge-protected and sent to a 400 V distribution board without extra switchgear.

3. Agricultural Barns & Dairy Sheds

The Type-2 SPD protects milking machines, ventilation fans and feed systems from lightning surges, while individual MCBs let farmers isolate one inverter without shutting down the entire PV cluster.

4. Distributed 6-Pod Industrial Sites

Each MCB acts as a local disconnect for a separate building wing or pod; the common MCCB simplifies metering and grid connection, while the SPD guards the whole site against transient over-voltages.

5. Ground-Mounted Sub-Arrays up to 600 kW

Factory-wired busbars and V-clamp terminals cut on-site assembly time for tracker or fixed-tilt rows, delivering a plug-and-play combiner that merges six inverter outputs and provides inverter-ready AC protection in one weather-proof box.
