RailUp for MultiRail

For the installation, we recommend using this component in very hot regions or for the optimisation of module performance. RailUp is supplied as a kit and does not require any additional material for the installation.

Cross-bracing with SingleRail

It can be expanded with a second rail layer (cross-bracing) using the Climber set and SingleRail, which also enables vertical assembly of the modules (portrait).

Lightning protection and equipotential bonding

Our lightning protection clamp set can be placed directly on the MultiRail. Aluminium conductors are therefore directly connected for lightning protection.

PVX Minimount

Our well-suited Performa mesh trays are high quality and rust-free. Installed without tools, secure, galvanically isolated cable ducting can be ensured.
