Single Phase DC+AC Combiner Box 600V 1000V 2 In 2 Out Industrial Box

The Single Phase DC+AC Combiner Box 600V 1000V 2 In 2 Out Industrial Box, supplied by China manufacturer Zhejiang Soutya New Energy LLC, is a 600 V – 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 houses three cage-type rotary DC isolator switches—dedicated to PV string-1, string-2 and battery-string circuits—plus two 1000 V DC surge-protective devices and three gPV fuse holders that deliver over-current and over-voltage protection while providing visible-break isolation. Factory-wired DC buses, positive, negative and PE, ensure dependable grounding continuity. On the single-phase AC side an integrated 2-pole RCBO 40 A 30 mA Type A, two single-pole MCBs and one 275 V AC surge arrester are mounted behind a flame-retardant partition, giving maintenance-safe load-break, earth-fault and surge immunity in one wall-lockable cabinet. Engineered for 2-string PV plus BESS sub-arrays, it provides essential combining, manual isolation and equipotential bonding for light-industrial rooftops, car-port canopies and small-commercial systems up to 15 kW.

1. Small Commercial Rooftops

The 2-string input capacity and single-phase output align perfectly with 5–15 kW rooftop arrays, letting installers combine and isolate DC inputs while receiving a ready-made AC feed for the existing 230 V distribution board.

2. Car-Port & Canopy Structures

Its shallow, IP65 wall-mount enclosure fits inside narrow pillar beams, giving parking shelters a neat, lockable point where PV strings, battery back-up, and inverter AC are merged and safely shut down during vehicle maintenance or cleaning.

3. Light-Industrial Facade BIPV

UV-stabilised polycarbonate and front-door rotary handles allow flush mounting on office or warehouse walls, providing maintenance teams with visible-break isolation of both PV strings and the battery string without entering the building.

4. Agricultural Barns & Dairy Sheds

The integrated RCBO and AC/DC surge arresters protect milking machines, coolers and feed systems from lightning-induced transients common in open fields, while the three dedicated isolators let farmers disconnect PV, battery or load circuits independently.

5. Ground-Mounted Sub-Arrays up to 15 kW

Factory-wired DC buses and single-phase AC section reduce on-site assembly time for tracker or fixed-tilt rows, delivering a plug-and-play hub that combines two PV strings, one battery string, and inverter output in one weather-proof cabinet.
