String combiner boxes for photovoltaic systems

It is necessary to use string combiner boxes to provide ideal protection for PV systems against lightning strikes and overvoltages. Our turnkey string combiner boxes, which can be connected immediately, are reliable system solutions that protect the inverter directly from DC and AC voltage inputs. Overvoltage couplings are diverted directly to the ground potential.

Advantages:

  • All sets in dust- and water-jet-proof housings (IP65)
  • Fast installation and startup with preassembled string combiner boxes
  • Creation of customer-specific solutions at short notice
  • Maintenance-free connection of PV strings with SUNCLIX or Push-in connection technology
  • For all photovoltaic sets with SUNCLIX connection technology, the required connectors are already included as standard
  • Standard-compliant switchgear and controlgear assembly, thanks to the use of DIN EN 61439
