DC+AC Combiner Box 600V 1000V 2 In 2 Out Home Box

The DC+AC Combiner Box 600V 1000V 2 In 2 Out Home Box, supplied by China manufacturer Zhejiang Soutya New Energy LLC, is a 1000 V DC / 400 V AC hybrid protection unit constructed with a UV-resistant polycarbonate housing and IP65-rated sealing for long-lasting outdoor performance. The enclosure houses two independent DC channels—each with a 2-pole MCB and a 1000 V DC SPD—and one AC channel with a 2-pole MCB plus 275 V AC SPD, while factory-wired positive, negative, line, neutral and PE busbars ensure dependable grounding continuity. Engineered for dual-string PV sub-arrays up to 15 kW, it provides essential over-current protection, surge suppression and manual isolation for both DC and AC circuits in a single, compact enclosure without additional sub-panels.

Technical Parameter

Application scenarios

1. 8–15 kW residential rooftops where two-string arrays need individual DC protection before a single 5–10 kW hybrid inverter, while the 230 V AC output is simultaneously safeguarded and isolated in the same wall-mounted box.

2. Agricultural greenhouse or barn installations that demand IP65 sealing against 24-hour humidity and irrigation mist, yet require both DC and AC surge arresters inside one enclosure to protect the inverter and downstream utility meter.

3. Car-port or canopy PV structures where dual MPPT inputs feed a compact inverter and rapid-shutdown rules call for a lockable, handle-operated AC/DC disconnect within arm’s reach of the array.

4. Small C&I rooftops (three-phase 400 V) that parallel two high-voltage strings (Up to 1000 V) and need local isolation of the inverter’s AC branch before the main distribution board.

5. Retrofit or expansion projects adding a second string to existing 5 kW systems; the box provides code-compliant DC fusing and AC over-current protection without installing an extra sub-panel or separate SPD rack.
