Beavertail replacement board
Intro
Before starting assembly, please carefully read the safety instructions, which can be found at the end of these assembly instructions. Before starting installation, please make sure that you use the latest assembly instructions.
The installation system should be designed and planned using the Alumero Solar.Pro.Tool software. Please refer to the project report, which you will receive from the Solar.Pro.Tool or from your Alumero sales partner, for the required materials and the positions and arrangement of the individual components. This data is calculated statically and is of great importance for the safe and flawless functioning of the system.
Before installation, the installer of the photovoltaic system must ensure that the given roof substructure is designed for the additional loads that arise.
These assembly instructions explain the assembly processes of the eponymous system, the attachment to the roof substructure and the installation of the modules.
In the case of sheet metal roofs, the modules are usually mounted vertically so that the support profiles are parallel to the ridge. Two carrier profiles per module row are used as standard.
ALUMERO photovoltaic systems are designed exclusively to accommodate PV modules. Any other use is considered improper use.
The system is designed exclusively to accommodate PV modules. Any other use is considered improper use.
Assembly may only be carried out by trained specialists. In particular, work on the roof covering should be carried out by a roofer.
If you have any further questions, please use ALUMERO's professional and comprehensive consulting service. Our competent civil engineers and construction technicians are happy to help you.

beaver tail replacement plate
Assembly
Make an opening
Position and tighten the beaver tail replacement plate.
Apply compression tape just below the screws.
Install roof hooks as described in the easyFlex assembly instructions.
Put beaver tail bricks back in position.
Assembly modules
Install end clamp
Start with the lowest row of modules. Place the first module on the carrier profiles and align them.
Click the Click end clamp slightly at an angle and push it towards the module frame.
Allen screw with a torque of 15 Nm tighten.
The presentation is exemplary and depicts the system, tending not to the profiles used.
Please note: The end clamps must be attached at least 20 mm from the end of the respective mounting profile.
Attention: When using end clamps with threaded plates, attention must be paid to the orientation. The threaded plate must be positioned transversely to the profile channel.
Install the center clamp
Place the Click center clamp on the frame of the previous module and click in at a slight angle. Push the module so that both modules are firmly in place.
Allen screw with a torque of 15 Nm tighten.
The last module in a series of modules with terminators, as before
described, assemble. Assembly of the remaining module rows analogously.
The presentation is exemplary and depicts the system, tending not to the profiles used.
Please note:
- Distance from the clamp to the ends of the support profile: min. 20 mm!
- Middle clamps must not be mounted directly on the support joint!
- Clamp the modules only at prescribed mounting areas! These can be found in the module manufacturer's data sheet.
- Distance (horizontal and vertical) between modules: approx. 20 mm!
module cable | potential equalization | grounding
Fasten module cable
Module cables should not hang down or rest on the roof covering. Push the clip attached to the cable tie into a profile channel of the support profile. Use the cable tie to tie the cable together.
Remove the clip by sliding it laterally out of the profile channel.
Potential equalization
Potential balancing between the individual plant components must be carried out in accordance with the respective country-specific regulations. One way of grounding the ALUMERO sheet metal folding roof system is shown below. Cable averages and overall grounding concept are not included in these instructions and must be calculated or prepared by the contractor in accordance with the applicable standards and guidelines. Professional grounding methods other than those listed here are also possible.
Grounding of carrier profile rows
In each row of carrier profiles, insert a wire clamp into the lower profile channel of the carrier profile. Insert the aluminum wire into the wire clamp and secure by tightening the screw. In this way, connect all rows of modules to each other conductively.
Earthing the modules
Whether the modules need to be grounded is specified by the module manufacturer in the respective module data sheet. If so, the potential equalization of the modules can be created in the following way, recommended by ALUMERO:
To integrate the modules into potential equalization, you can use ALUMERO end and middle terminals with pins. The pins sit in the terminals, pierce the anodized layer of the module frames and thus conductively connect all module rows together.
All product images included in these assembly instructions are for illustrative purposes and are not true to scale. Subject to changes and errors!
Optional: potential equalization | grounding
Install grounding/potential equalization
The grounding/potential equalization is attached to the edge of a module field on a foot with a screw (max. M8). The components are not included.
- Securely connect the ground wire (on site) to the cable lug.
- Install the shim and cable lug with the screw in the order shown.

Important warnings
Solar modules generate electricity as soon as they are exposed to light and are therefore always under voltage. Although the fully insulated plug contacts provide protection against contact, you must pay attention to the following when handling the solar modules:
- Do not insert any electrically conductive parts into the plugs and sockets.
- Do not install solar panels and cables with wet plugs and sockets.
- Perform all work on the pipes with extreme caution.
- Do not perform an electrical installation when it is damp.
- Even with low lighting, the series connection of solar modules produces very high DC voltages, which are life-threatening when touched. In particular, consider the possibility of secondary damage in the event of electric shock.
High contact voltages can occur in the inverter even when switched off:
- Be particularly careful when working on the inverter and cables
- After switching off the inverter and carrying out further work, be sure to follow the time intervals specified by the manufacturer so that the high-voltage components can discharge.
- Please also note the inverter manufacturer's installation instructions.
- Opening a closed string (e.g. when disconnecting the DC line from the inverter under load) can result in a deadly arc:
- Never disconnect the solar generator from the inverter while it is connected to the grid.
Standards and guidelines
All standards and guidelines listed have been published and applied for Germany. They must be considered in their current version. Outside of Germany, please also comply with the relevant national standards and guidelines.
