- Our best-selling system - over 2 GW installed worldwide
- All-rounder with only 4 installation steps - also suitable for high load
K2 BasicRail System
System variant
BasicRail 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.
We recommend using this component in very warm regions or to optimise module performance.
RailUp is supplied as a set and does not require any additional material for installation.

Installing on sandwich panels with abZThe direct connection of BasicRail with BasicClips and self-tapping screws on sandwich panels has a general building approval (abZ) from the DIbT for some sandwich panel manufacturers. This type of installation with building authority approval is unique in Germany.
It requires little time, which results from the high installation speed of the BasicRail system and the direct fastening of the system in the sandwich panels.

The FlexAdapter can be inserted into the K2 BasicRail as an additional component to compensate for different overlap angles of imitation-tile sheets and the curvature of barrel-vaulted roofs. It is attached using the BasicClip and CSM Adapter, along with an EPDM pad for underlay and sealing.
