optimize energy yields, protect animals securely.

Are you planning to build a wind farm and need help with bat protection solutions?
You are operating a wind turbine and would like more relief in monitoring and documentation? Are you already experiencing enormous energy losses due to faulty shutdowns, perhaps you are even in conflict with the authorities and are looking for ways to operate your wind farm more efficiently?

We have a solution for you: the Fleximaus! Our smart optimization system adapts to the individual specifications of your wind turbine, both new and existing, and ensures a reliable, economical and approval-compliant bat protection.


Your advantages

  • Comprehensive documentation
  • Noticeable reduction in workload
  • Proven solutions

Our bat protection system provides more time to produce green energy

The implementation of shutdown requirements for bat protection is complex and has to be parameterised individually at each site.

What if there was a simple way to comply with all approval-relevant requirements for bat protection, reduce the effort required for operational management and increase the productivity of your systems at the same time? At Fleximaus, we know that it is possible to reconcile different requirements.

Based on many years of experience, we have developed an intelligent software that helps you both, increase your energy output with minimal effort and protect native bats

kWh additional yields per year

You would like to integrate our bat protection into your wind farm?

The way from a normal wind turbine to a species protection wind turbine │ How the intelligent bat protection works :

The basis for the work of Fleximaus is formed by surveys at the customers' wind turbines and several years at turbines all over in Europe. Bat experts carry out a one-off survey at your wind farm - bat monitoring. This enables them to determine the environmental conditions (outside temperature, wind speed, rain intensity or time of day) under which bats are most likely to be present in the rotor area.

The Fleximaus compares the expert's specifications with the actual prevailing environmental parameters and switches off your wind turbines at precisely the times when bats are likely to approach them. Once the danger has been averted, our optimization system brings your rotors back into operation almost as quickly. Always with the aim of avoiding unnecessary downtimes and protecting the endangered species.

If the Fleximaus is used in parallel with bat monitoring, our environmental data can also be incorporated into the bat behavior monitoring. The result: a far more precise bat shutdown adapted to the site-specific behavior of the aerial acrobats as well as an even more species-friendly and economical wind farm operation.


The Fleximaus keeps you informed about all steps: Wind farm operators can both track the conditions prevailing at the wind turbine from different mobile devices in real time and also understand bat shutdowns that have been carried out at any time.

What distinguishes Fleximaus from other systems?

Return of investment

Due to the increase in efficiency associated with the Fleximaus, the expenses for a retrofit - depending on the size of the wind farm - pay for themselves within a few months.


We constantly check the functionality of the Fleximaus: Technical faults are reported to our team immediately, so that we are able to rectify almost any error as quickly as possible via remote monitoring.

Legal certainty

The Fleximaus guarantees the legally secure fulfilment of all requirements of the permit notice. This means that no penalties are imposed by the authorities due to missing or incorrect bat protection switch-offs.


Our manufacturer-independent system can be used in new wind farms as well as existing turbines. In addition, specifications for the bat and bird protection will be individually configured and adapted at any time.


By using our smart software algorithm, you avoid unnecessary downtimes of your turbines. Among other things, it implements the night separation (divide the night into ten time slots with different protection rules) and using of our patented wind farm wind speed.

Reaction Speed

Our optimization system is able to collect and process numerous environmental data (every minute or ten minutes) and to integrate data from real-time acquisition systems such as cameras into the shutdowns.


The day-by-day observation of sunset and sunrise reduces the observation time by additional hours per month. In addition, the plausibility of the environmental data is checked.

Accuracy of fit

All Fleximaus environmental sensors are selected according to the respective area of application and form the basis for optimum site-specific species protection.


Both external environmental sensors already present in the wind farm and recording systems that will only be approved in the future can be integrated into the Fleximaus interface.


We work with high-quality industrial components and have designed our specially developed software modules so that they can also be used on future hardware.


Our system documents environmental data - so you can track the bat protection at any time with the help of clear data tables and prove them to the authorities.

Still unsure?

Put the Fleximaus to the test and install our optimization system for a one-year trial!

Optimally positioned in every situation:

Optional extensions and sensors

Bats fly after dark, hunt more selectively over bodies of water when it rains, and are rarely seen in the direct vicinity of rotor blades above a certain wind strength - but not always and everywhere. In order to predict the site-specific flight behavior of the endangered animals during different events, Fleximaus measures and observes numerous environmental parameters and compares them with the studies of the bat experts.

- Parking wind speed to reduce unnecessary downtimes


Every new wind farm with an interface for third-party systems can be optimized with Fleximaus. We would also be happy to check the use of Fleximaus on your existing old systems and retrofit the necessary technology at a still economical price. This can increase species protection and environmental protection because old turbines can be operated for longer and can now also be equipped with bat-friendly operation.

Comprehensively clever in the wind:

Yield & species protection work togehter

Our solutions guarantee absolute reliability and maximum performance for all relevant specifications. You simply select the software modules you need and we accompany your project from start to success.

Bird protection >

Our solutions >>

Our smart system takes over the reliable implementation of permit-relevant requirements for bird protection for you: elaborate specifications are implemented automatically, event-dependent stops can be activated very easily.

Shadow switch-off >

Our solutions >>

If mandatory shadow periods are exceeded, operators must limit the running time of their rotors. The Fleximaus automatically takes care of this shadow switch-off of wind turbines for you.

Are you satisfied with the energy yield of your wind farm?

Find out which energy potentials are slumbering in your turbines!

With the FlexiCheck we determine the potential in your wind farm and show you whether the discussion about adjusting the shutdown criteria is worthwhile. With the help of historic data, you can see what additional energy yield the Fleximaus will generate for you annually and can support the investment in your wind farm with well-founded figures.
