System highlights

With elevation for more yield

from our flat-roof system Dome 6 can produce a better angle of incidence with the elevation and thus a higher yield. The clever connection for trapezoidal sheeting is safe in terms of holding force and economical in terms of material and transport.

K2 MultiRail High

With the new MultiRail High, which has a height of 100 mm, installers gain increased clearance in thermally demanding environments. The extra space beneath the module also allows the integration of micro‑inverters or power optimizers. The MultiRail High measures 150 mm in length and is secured with four thread‑forming metal screws, ensuring reliable water tightness together with the EPDM sealing.

There are two dedicated versions:

• for trapezoidal sheet metal: MultiRail High (2004704)

• for corrugated sheet metal: MultiRail High CSM (2004706)

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.
