At Hahn Kompost, the SENNEBOGEN 826 G Electro Battery is used to feed a waste wood shredder. The electric material handler operates primarily on mains power; a battery pack allows for approximately one to two hours of off-grid operation when needed. This enables the company to combine the use of self-generated solar power with the flexibility to move the machine without cables.
Hahn Kompost is active in the processing of waste wood and green waste, composting, and wood chip production. To reduce the use of fossil fuels and consistently utilize renewable energy, the company is gradually converting its facilities to electric operation. The first step is the waste wood processing line, which now uses an electric shredder, wheel loaders, and the SENNEBOGEN 826 G Electro Battery A photovoltaic system supplies the electricity generated on-site for this purpose. “We simply want to move away from fossil fuels and use the energy we produce ourselves,” explains Managing Director Michael Hahn.


At Hahn Kompost, the 826 G Electro Battery is used to feed the waste wood shredder. Since the machine primarily operates on the power grid, the decision was made to use just one battery pack instead of the four available. Depending on operational requirements, SENNEBOGEN battery-powered machines can be equipped with one to four battery packs. This allows the battery capacity to be customized to the specific operation. At Hahn Kompost, the single battery pack is primarily used to disconnect the machine from the power cord when necessary and to move it flexibly, for example, for maintenance work or other tasks. Without a mains connection, the machine can operate for approximately one to two hours.
“The only reason the battery pack was important to us was so that we could move the machine around,” says Michael Hahn. The chosen configuration demonstrates how battery technology can be specifically tailored to the actual application and operational requirements.
Machine operator Franz Traidl is also convinced of the advantages in his day-to-day work. He knows how it compares to a diesel machine from his own experience. For him, the lower noise level, ease of operation, and reduced maintenance requirements make all the difference.
“You have less maintenance because you no longer have air filters, no need to refuel, no AdBlue, and it’s significantly quieter,” Traidl summarizes.
Especially when working indoors, the quiet electric operation ensures pleasant working conditions. The audio comfort system with active noise cancellation provides additional support. The precise controls are also impressive: The machine responds immediately to joystick movements and can be operated with great sensitivity. Using the SENcon control system, Traidl can also customize lift speeds and functions.
For Managing Director Michael Hahn, the economic benefits are just as important as the convenience. The electric drive requires no diesel or AdBlue, reduces maintenance costs, and allows the use of self-generated electricity.
“Our new machine actually pays for itself relatively quickly because we save on all the diesel,” explains Hahn. The investment was carefully calculated and makes economic sense for the business. In addition, the interaction between the handling machine and the shredder via the SENcon system ensures a coordinated work process and efficient feeding of waste wood into the shredder.
After about two months of use, the verdict is positive. The machine meets expectations in terms of performance, noise levels, and comfort. For Franz Traidl, one thing is certain:
Hahn Kompost is also already planning its next steps: The composting plant and the vehicle fleet are also set to be electrified in order to further reduce emissions and use the company’s own electricity even more efficiently.
The fact that Hahn Kompost relies on SENNEBOGEN for this is also due to their long-standing partnership. The proximity to the SENNEBOGEN sales office, the spare parts supply, and the quick support from customer service give the company added peace of mind.
