Details on components:

The K2 Buddy – TopBox Set Snow contains two snow sensor units that precisely measure the snow load on a PV module. These sensors are installed with the Dome 6 system using components from the Dome accessory set and are permanently connected to the TopBox (plastic housing with encapsulated circuit board) by cable. The snow sensors are positioned on the left and right below the bottom corners of a PV module. The TopBox evaluates the measured values and transmits them by cable to the K2 Buddy - BaseBox in the building services. The power supply (24 V) is also provided via the same cable.

The K2 Buddy – BaseBox Set consists of a top-hat rail housing with integrated circuit board and a top-hat rail power supply unit. It is mounted in a weather-protected location in the building services connection room. The BaseBox monitors the measurement data of the TopBox on the roof at regular intervals (every 10 minutes) and transmits it to the cloud via the house's internet connection. It also monitors the power supply to the TopBox and switches it off in the event of a fault to ensure smooth operation.

The mounting rail set for the assembly of the K2 Buddy contains two BasicRail rails with a length of 1.30 m and two square profiles, also 1.30 m long. The two additional BasicRail mounting rails are necessary for mounting the K2 Buddy. The square profiles are designed to stabilize and reinforce the frame construction.

The Dome accessory set offers all the necessary accessories and small parts to safely install the TopBox Set Snow in the K2 Dome flat roof systems. Among other things, it includes an aluminum plate that supports the snow sensor units and securely connects the BasicRails. In addition, it contains specific module stops for precise measurement data acquisition as well as lift-off protection and cable managers to ensure safe installation.
