To provide optimal protection of the various rooftop system parts from direct lightning strikes and surge voltages, it is necessary to use string combiner boxes. Phoenix Contact offers an extensive portfolio of various ready-to-install, directly connectable string combiner boxes for your rooftop systems.

Your advantages

  • All sets in dust- and water-jet-proof housings (IP65)
  • Fast installation thanks to the pre-assembly of the photovoltaic sets
  • Maximum degree of safety in case of maintenance or danger
  • Standard-compliant switchgear assembly, thanks to use of DIN EN 61439

Protect against surge voltages

Surge protection for PV rooftop systems  

Pre-assembled PV sets reliably protect rooftop systems

With its pre-assembled sets, Phoenix Contact offers reliable system solutions that protect the inverter directly upstream of the DC and AC voltage inputs.

Surge voltage couplings are discharged directly to the ground potential. Due to our coordinated scope of supply, new versions can be made available very quickly.

Connecting

For connection of the PV strings, string combiner boxes are equipped with either our SUNCLIX panel feed-throughs or with cable glands on Push-in terminals. SUNCLIX connectors from Phoenix Contact as well as Push-in terminals combine the advantages of simple installation with reliable and maintenance-free connection.

Disconnecting and isolating

We offer both a fire department emergency shutdown or load disconnecting switch as well as surge protection in a single device. Using an emergency stop switch, it is possible to disconnect the photovoltaic system remotely, thus offering the greatest possible safety in case of maintenance or danger.
