Direct answer
A 1500V DC combiner box is used in PV systems designed around 1500V string architecture. All internal components must be rated for the same voltage class.
This page is for procurement planning. The final layout should be confirmed from string voltage, current, inverter input and protection requirements.
Core procurement parameters
| Voltage class | 1500V DC |
|---|---|
| String count | 4, 8, 12, 16 or custom inputs |
| Protection | 1500V fuses, SPD, isolator, MCB/MCCB |
| Related BOS | 1500V cable and connector package |

FAQ
What makes a combiner box 1500V?
The enclosure design and all internal devices, including fuses, SPD, isolator and output protection, must be suitable for 1500V DC use.
Can 1500V combiner boxes ship with 1500V cable?
Yes. We can coordinate cable, connectors and combiner boxes in one BOS shipment.
