In the tutorial, we show you how to install the MultiRail PV mounting system on roofs with trapezoidal sheet metal and thus securely fasten a solar installation. Simple and quick installation of the MultiRail system:

• Presentation by Giuseppe Fruci of K2 Systems.
• Description of the two types MultiRail 10 and 25 with EPDM seal for different load cases
• Fixing: self-sealing thin sheet metal screws directly on the high bead of the trapezoidal sheet metal
• Placement or quantity of MultiRails in the edge and corner areas – even with high wind loads
• Spacing gauge between the MultiRail rows: Use Tip Dome Speed Spacer
• Note on the placement of the MultiRails: Exact specification from the K2 Base assembly plan
• Mounting modules and module clamps
• Note on landscape orientation and portrait mounting with SingleRail cross-connection
• Thermal separation with the MultiRail system

The MultiRail mounting system for photovoltaic systems has been specially developed for trapezoidal sheet metal roofs. This short-rail system is very easy to install and is particularly aimed at cost-sensitive projects with low transport volumes or weights. This system is mainly installed with landscape orientation (horizontal), but with a second rail layer via cross connection with SingleRail, portrait orientation (vertical) is also possible.
