Super Multi Box - Smart DC Combiner Q3

Advanced DC Combiner with 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 detected, selectively isolated, and permanently disconnected — all other strings continue operation without interruption. System availability is maintained!

Designed for large-scale PV systems with central inverters, this solution integrates numerous safety and communication features into a robust IP66-rated steel enclosure:

⚙️ Individual string current monitoring for up to 24 inputs
⚙️ Electronic DC disconnection up to 480 A at 1,500 V DC
⚙️ Integrated PV fault manager with remote maintenance capability
⚙️ Surge protection device (SPD) Type 1+2 with remote signalling contact
⚙️ Fuses on the positive and optionally also on the negative pole (32 A / 1,500 V DC)
⚙️ Communication interfaces: Modbus TCP/IP, RS485, Ethernet or USB
⚙️ MC4-EVO2 input connectors and copper busbar output
