1000V DC Combiner Box 6 In 2 Out Isolator type

The 1000V DC Combiner Box 6 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, 12 DC fuse holders, and 2 cage-type DC isolator switches. It is designed to deliver comprehensive isolation protection, leakage protection and grounding protection in 6-string photovoltaic systems.

Application scenarios

1.Large Commercial & Industrial Rooftop

This combiner box is ideal for large commercial rooftops (e.g., factories, warehouses,shopping malls) supporting up to six PV strings.. The box rolls them into two independent outputs, so heavy loads can be split between inverters while twin isolator switches give lock-out in seconds. IP66 keeps dust, humidity and roof-top heat out all year round.

2.Utility-Scale Solar Blocks

Slides onto tracker tables in 10–100 MW blocks. Six sub-arrays feed in, two homerun cables go out—each with its own isolator—letting O&M crews shut down half the block for string replacement without touching the rest. Dual SPDs soak up nearby lightning hits.

3.High-Power Agriculture

Clips to barn or pivot-irrigated fields where six strings power pumps, chillers and grain dryers. Individual fuses per string stop a ground fault in one furrow from shutting down the whole crop-water line. UV-stable IP66 shell laughs at fertiliser dust and daily wash-downs.

4.Solar-Storage Hybrids

Mounts on the battery hut: six strings in, output A to the hybrid inverter, output B to the MPPT charger. Either leg can be isolated with a twist of its own handle, so techs can swap batteries or reboot the inverter without darkening the critical load.

5.Remote Telecom / Off-Grid Stations

Straps to the pole behind six slimline panels feeding redundant DC rings for radios and sensors. Fire-retardant, IP66 enclosure survives -40 °C nights and desert sun, while the two output legs keep comms gear alive even when one side is down for service.
