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

The DC+AC Combiner Box 600V 1000V 1 In 1 Out Home Box, supplied by China manufacturer Zhejiang Soutya New Energy LLC, is a hybrid photovoltaic/storage interface unit constructed with a UV-resistant polycarbonate housing and IP65-rated sealing for long-lasting outdoor performance. Inside, the DC section contains one 2-pole MCB and one 1000 V DC SPD to deliver over-current protection and surge suppression for the incoming string, while the AC section houses one 2-pole MCB and one 275 V AC SPD to safeguard the inverter output. Factory-wired positive, negative, line, neutral and PE busbars ensure dependable grounding continuity. Engineered for 5–15 kW residential or small-commercial systems, it provides essential isolation, protection and equipotential bonding in a single, compact enclosure without additional sub-panels.

Technical Parameter

Application scenarios

1. Single-phase 5–15 kW rooftop systems where the hybrid box merges DC string input and 230 V inverter output before a single wall penetration, saving cable and space.  

2. Small car-port or canopy PV arrays that need lockable DC/AC isolation plus Type-2 SPD protection within arm’s reach for O&M crews.  

3. Agricultural greenhouse installations that demand IP65 sealing against 24-hour humidity and irrigation mist while housing both DC and AC surge arresters in one enclosure.  

4. C&I rooftops using 600 V–1000 V string voltage and 400 V three-phase inverters that require a compact, weather-proof interface at the edge of the array.  

5. Retrofit battery-ready sites where an existing string is upgraded to hybrid (PV + storage) operation; the box provides compliant DC and AC protection without rewiring the main distribution board.
