- GehrTec® Nubbel
The efficient pre-assembled cable system for photovoltaic systems
The cabling system for ground-mounted and roof-top photovoltaic systems of all sizes. The economical and safe option for connecting PV modules with inverters for large-scale ground-mounted or roof-mounted systems.
Your Advantage
Optimal economy
GehrTec® Nubbel offers quick and effective DC cabling with few possibilities of faults and low transition resistance.
Installation is simple and reduces installation costs. The Nubbel system is pre-assembled in acc with requirements and reduces the cable lengths needed compared to a conventional system by up to 60%.
Highest quality and safety
GehrTec® Nubbel is manufactured in Germany. The ideally adjusted position of the branches enables optimal cable
laying. By minimizing inductive coupling faults are avoided. The casing of the cable consists of a continuous fully networked material and ensures absolute and permanent resistance to weather.
Competent service
The connection is reverse polarity protected by pre-assembling MC-connectors at the works. Manufacture is in acc. with customer-specific requirement.
