1000V DC Combiner Box 2 In 2 Out Isolator type

The 1000V DC Combiner Box 2 In 2 Out Isolator type, supplied by China manufacturer Zhejiang Soutya New Energy LLC, is a 1000 V DC PV combiner unit featuring a fire-retardant PC enclosure and IP66 protection that ensures high durability and reliable outdoor performance. The device integrates critical safety components including 2 DC surge protective devices, 4 DC fuse holders, and 2 heavy-duty cage-type DC isolator switches. It is designed to deliver comprehensive isolation protection, leakage protection and grounding protection in dual-string photovoltaic systems.

Application scenarios

1.Dual-Input Commercial Rooftop

Purpose-built for shops, offices and showrooms that want two PV strings on one roof yet keep the outputs separate. The slim 2-in/2-out box slips between beams, twin isolators give lock-out visibility in seconds, and individual SPDs protect each string—no extra fuse-holders needed.

2.Industrial Dual-Circuit Feed

Slides onto factory parapets where one array keeps the line running and the other backs up the control room. IP66 shell shrugs off dust and wash-down, while the two rotary isolators let maintenance crews kill either side live without shutting the whole floor down.

3.Farm “Split-Load” Arrays

Fits on barn or greenhouse guttering to power irrigation pumps on circuit A and grain dryers on circuit B. Each isolator sits under its own clear cover, so farmers can disconnect the pump loop for winter service without touching the dryer feed.

4.Solar-Storage Hybrids

Mounts on the battery hut wall: input 1 heads to the hybrid inverter, input 2 to the MPPT charger. Dual isolators allow safe storage-side lock-out during battery swap, and built-in surge counters show if the overnight storm hit either leg.

5.Remote Telecom Towers

Clamps to the pole behind two slimline panels feeding redundant DC supplies for radios and sensors. Fire-retardant PC box handles -40 °C nights and blazing sun, and the two isolators give tower techs a visible break before they climb.
