DC+AC Combiner Box 600V 1000V 1 In 1 Out Industrial Box

The DC+AC Combiner Box 600V 1000V 1 In 1 Out Industrial Box, supplied by China manufacturer Zhejiang Soutya New Energy LLC, is a hybrid photovoltaic combiner-isolator unit constructed with a UV-stabilised polycarbonate housing and IP65-rated sealing for durable outdoor deployment. The enclosure integrates a 600 V / 1000 V DC surge-protective device and rotary load-break isolator on the PV side, while the AC side hosts a 275 V surge arrester, one 2-pole RCBO 40 A 30 mA for combined earth-fault and over-current protection, plus two single-pole MCBs (40 A & 20 A) for load and SPD disconnection. Factory-mounted on 35 mm DIN rails with colour-segregated DC/AC wiring and an internal flame-retardant partition, the box delivers single-string PV combining, manual isolation and comprehensive surge immunity in a wall-mount, pad-lockable cabinet rated for light-industrial, car-port and small-commercial systems up to 15 kW.

1. Small Commercial Rooftops – Provides a one-box solution for isolating and combining a single high-current string before connection to a 5–15 kW three-phase inverter, eliminating multiple wall-mounted devices.

2. Car-Port & Canopy Arrays – Its IP65 polycarbonate shell resists exhaust heat, road salt and hose-down cleaning, making it ideal for shaded parking structures where space is tight and aesthetics matter.

3. Light-Industrial Facade BIPV – Thin profile and pad-lockable door allow flush-mounting on cladding or parapet walls, giving maintenance crews safe DC and AC shutdown at one visible point.

4. Agricultural Barn & Dairy Sheds – Surge arresters on both DC and AC sides protect sensitive milking, cooling and feed equipment from lightning-induced transients common in open-field installations.

5. Ground-Mounted Sub-Arrays up to 15 kW – Factory-wired busbars and RCBO earth-fault protection accelerate field assembly of tracker or fixed-tilt rows, reducing labour time and balance-of-system cost.
