Nexus Fortress
The ultimate solution for DC connector and array wiring installation.
Nexus Fortress is a modular protection and installation Product line that industrializes how DC connectors and array wiring are handled in solar parks. It creates a defined, protected and repeatable environment around every connection, so installation quality is no longer left to chance on site.
The system works with all common solar modules, DC connectors and cable types, and can be configured for virtually any string layout, mounting structure or cable route.
Built for a modern solar industry that demands industrialised, reliable DC installations in the field
Nexus Dock
The first step to a controlled DC installation
Nexus Dock is the starting point for a high-quality DC installation. It manages unmated connectors and array cabling during the initial build, so the rest of the process is structured from day one.
Fits virtually all solar module frames and installation needs
Integrated connector cap for unmated connectors
Safe, defined placement of capped connectors, during installation and even transport - without increasing packing height
Integrated cable cradle and force distribution for optimal cable management
Designed to enable and interface directly with Nexus Guard.
Nexus Guard
Full protection for connectors and cables.
Nexus Guard takes over where Nexus Dock leaves off. It provides the final, protected installation environment for mated connectors and cables from operation to decommissioning.
Protection against mechanical, environmental, heat and UV stress
Proper strain relief for connectors and DC cables
No direct contact on the connector body, supporting long-term reliability
Optimised inspection capabilities, including visual and drone inspection
Increased electrical safety for technicians and animals, with reduced fire risk
Fulfils product, installation and safety needs for a reliable DC installation

Installation & workflow
Nexus Fortress is designed for efficient, repeatable installation on site with minimal disruption to existing workflows. The system is quick to mount on existing structures and replaces sub standard and improvised methods such as loose cable ties, tape, or brackets unsuitable for installation.
Installers follow a clear, guided process that standardises how connectors and cables are placed, protected, and secured – making it easier to train teams, maintain quality, and document the final result.
For staged or phased work, Nexus Fortress also includes integrated cap/plug handling for unmated connectors, so temporary states remain protected, compliant, and easy to manage until final connection.
What it solves
DC cable and connector faults are among the top three causes of reliability issues and energy loss in solar installations – and a major cost driver and fire risk. In most cases, the problem is not the components themselves. But how they are installed, protected and exposed in the field.
For asset owners and investors, this means avoidable underperformance, unplanned interventions, higher costs and an increased risk profile.
The DC side of solar needs more structure, controlled and optimal placement, and real protection – while still fulfilling connector manufacturer requirements and complying with relevant standards and legislation.
This is exactly what we provide with Nexus Fortress.
