Connecting and cabling

DC connector  

Innovative connectors for quick and easy cabling

The innovative spring connection of the DC connectors enables cables from 2.5 to 16 mm² to be connected reliably and safely without special tools.

This facilitates particularly quick and easy on-site assembly.


DC Y-distributor  

Flexible distribution of the string currents thanks to Y-distributors

Y-distributors provide even more flexibility in photovoltaic cabling. Route adjacent strings easily and inexpensively to the inverter with only one string cable.

Assembling with connectors is also possible. Customer-specific cable lengths are available on request.

Device connection

String combiner  

Reliable connection of signals, data, and power

Phoenix Contact offers connectors and housing feed-throughs for the reliable transmission of signals, data, and power.

All components are made from high-quality, robust materials. They have undergone intensive laboratory testing and ensure the permanently stable connection of your devices.

Connecting building-integrated panels

Connecting building-integrated panels  

Variable junction box width according to customer requirements

One module junction box is used per position. Both module junction boxes are integrated into the building-integrated module and sealed with sealant. Their adaptable width enables module junction boxes to be integrated very easily.

Seamless connection technology from the photovoltaic panel through to feed-in

Connectors and cables facilitate fixed or flexible installation and are suitable for a temperature range of -40°C to +85°C.
