DC+AC Combiner Box 1000V 2 In 1 Out

The DC+AC Combiner Box 1000V 2 In 1 Out, supplied by China manufacturer Zhejiang Soutya New Energy LLC, is a 1000 V DC and 230 V AC hybrid combiner-isolator unit constructed with a UV-stabilised polycarbonate housing and IP65-rated sealing for durable outdoor deployment. The enclosure integrates one 1000 V DC surge-protective device, two gPV fuse holders and one 2-pole 32 A cage type isolator switch that deliver over-voltage and load-break protection to dual PV strings, while factory-wired positive, negative and PE busbars ensure dependable grounding continuity. On the single-phase AC side it houses one 2-pole RCBO 20 A 30 mA Type A and one 275 V AC SPD, all factory-mounted on DIN rails behind a flame-retardant partition. Engineered for 2-string PV sub-arrays up to 6 kW, it provides essential combining, surge immunity, earth-fault protection and manual isolation in one lockable, wall-mount cabinet.

1. Residential Rooftops (4–6 kW)

The 2-string input perfectly matches common household PV layouts; the box combines and isolates both strings before feeding a single-phase inverter, while the built-in RCBO and SPD protect indoor distribution boards from lightning and earth-fault events.

2. Car-Port & Garage Canopies

Its shallow, IP65 wall-mount enclosure bolts to narrow steel beams, giving parking shelters a lockable, visible-isolation point for PV circuits and a ready-made AC output for EV chargers or lighting circuits.

3. Agricultural Barns & Sheds

UV-stabilised polycarbonate and front-door rotary handle allow flush mounting on barn walls; farmers can disconnect PV strings independently when servicing ventilation or feed equipment, while the AC SPD guards milking machines from transients.

4. Light-Industrial Facade BIPV

The flame-retardant partition and transparent door let maintenance teams view breaker status without opening the cabinet, providing a neat, outdoor-rated hub for façade-integrated modules feeding a 230 V office switchboard.

5. Ground-Mounted Sub-Arrays up to 6 kW

Factory-wired DC buses and single-phase AC section reduce field wiring time for tracker or fixed-tilt rows, delivering a plug-and-play combiner that merges two PV strings and provides inverter-ready AC protection in one weather-proof box.
