800V AC Combiner Box 6 In 1 Out

The 800V AC Combiner Box 6 In 1 Out, supplied by China manufacturer Zhejiang Soutya New Energy LLC, is an 800 V three-phase inverter-combiner unit constructed, UV-resistant steel enclosure and IP65 sealing for durable outdoor performance. The enclosure houses six 4-pole AC molded case circuit breakers (160-250A ) that deliver individual over-current and short-circuit protection to each inverter input, while a single 4-pole AC MCCB (1000-1600A ) 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 Type2 4 pole 800V AC SPD guards against lightning-induced surges. Engineered for up to six solar string inverters (6*100-160 kW), it provides essential AC combining, surge immunity and maintenance safety.

Application scenarios

1. Utility Scale Ground Mount Blocks (600-960 kW)

The six 160-250 A molded case circuit breaker inputs accept up to six 160 kW string inverters; the 1600 A output MCCB feeds an 800 V medium-voltage transformer, reducing cable runs and trenching across large solar parks.

2. Central-Inverter Skid Substations

Mounted on the inverter rack, the 800V AC Combiner Box 6 In 1 Out acts as a “local AC hub” — paralleling six 800 V inverter outputs before a single large feeder to the MV switchgear, simplifying skid wiring and maintenance access.

3. Large Commercial Rooftops > 600 kW

IP65 steel housing and IK10 impact rating allow rooftop placement where space is limited; the 800 V rated components raise string voltage, cutting DC cabling costs while the 1600 A busbar carries the combined current to the building MSB.

4. Agricultural Greenhouses & Barn Clusters

The Type-2 800 V SPD protects ventilation fans, irrigation pumps and milking equipment from lightning surges common in open fields, while individual input MCCBs let farmers isolate one inverter without shutting down the entire cluster.

5. Distributed 6-Pod Industrial Sites

Each 160–250 A MCCB serves as a local disconnect for a separate building wing or car-port pod; the common 1000–1600 A output MCCB simplifies metering and grid connection, while the SPD guards the whole site against transient over-voltages.
