MultiRail System

    The MultiRail mounting system for photovoltaic assemblies was developed specifically for trapezoidal sheet metal. It blends roof connection with module railing in one single component.

     

    • Easy and proven – as a short rail or a flexible component in various lengths
    • Quick planning with less material and greater effectiveness
    • Solid base rail for trapezoidal elevation S-Dome Small

    RailUp for MultiRail

    MultiRail systems can now be planned with an elevation. This improves the rear ventilation of the modules and helps with the installation of micro-inverters and power optimisation.

    When installing, we recommend using this component in very warm regions or to optimise module­performance.
    RailUp is supplied as a set and requires no additional material for installation.

    Second rail layer with SingleRail

    Second rail layer with SingleRail

    The MultiRail system is normally built with horizontal modules (landscape). It can be mounted including a second rail layer with the Climber Set and SingleRail, which allows the modules to be mounted in portrait orientation.

     

    Lightning protection and equipotential bonding

    With the help of our TerraGrif K2SZ, simple and quick module­frame­groundings can be made for MultiRail systems. Our lightning protection clamp set can be placed directly on the MultiRail. Aluminium cables for lightning protection are thus connected directly.
