DC Isolator Box IP65 Enclosure Six Strings

The DC Isolator Box IP65 Enclosure Six Strings, supplied by China manufacturer Zhejiang Soutya New Energy LLC, is a 1500 V DC photovoltaic isolation unit constructed with a UV-resistant polycarbonate housing and IP65-rated sealing for long-lasting outdoor performance. The enclosure houses six cage-type rotary DC isolator switches that deliver visible-break isolation and maintenance safety, while factory-wired positive, negative and PE busbars ensure dependable grounding continuity. Engineered for hexa-string PV sub-arrays, it provides essential manual isolation and equipotential bonding.

Technical Parameter

Application scenarios

1. Utility-scale ground-mounted arrays ≥ 1 MW where six-string tracker harnesses need local, lockable 1500 V isolation for O&M crews.  

2. Large commercial rooftops or car-port canopies (50–80 kW blocks) that adopt 1500 V architecture to cut DC cabling costs and still meet rapid-shutdown requirements.  

3. Agricultural greenhouse installations that demand IP65 sealing against constant humidity, irrigation mist and 24-hour UV while providing a visible-break disconnect for every high-voltage string.  

4. Solar-to-hydrogen or EV-charging plants operating at 1500 V bus voltage, requiring reliable manual isolation of six-string sub-arrays before central MPPT or DC-DC converters.  

5. Retrofit or repowering projects that upgrade legacy 1000 V strings to 1500 V; the box delivers compliant isolation and future-proof spacing without enclosure replacement.
