⚡ Super Multi Box – the smartest DC combiner: enables safe, string-level switching and monitoring of large PV generators – including intelligent diagnostics and string-current monitoring.

⚡ Super Multi Box – the smartest DC combiner: enables safe, string-level switching and monitoring of large PV generators – including intelligent diagnostics and string-current monitoring.

Advanced DC combiner featuring patent-pending technology for selective fault detection at string level. In the event of a fault (e.g. insulation failure or arc fault), the affected string is identified, isolated and taken out of service, while all remaining strings continue operating. System availability remains fully intact!

Designed for large-scale PV systems with central inverters. Housed in an IP66 steel enclosure, it integrates numerous safety + communication functions

  • individual string current measurement for up to 24 inputs
  • electronic DC disconnection up to 480 A at 1,500 V DC
  • integrated PV fault manager with remote maintenance
  • SPD Type 1+2 with signalling contact
  • fuses in the positive and optionally in the negative pole (32 A / 1,500 V DC)
  • communication interfaces: Modbus TCP/IP, RS485, Ethernet, USB
  • MC4-EVO2 inputs & copper busbar output

The electronics are powered directly by the PV strings. At night, the system remains communicative thanks to internal battery buffering.
