the economical upgrade
for your project

Fleximaus is a play-on-words – We developed a flexible system for an economical bat protection in wind farms (in German bat is called Fledermaus). Fleximaus was developed by technical operation managers to guarantee wind farm operators and investors the best energy yields despite of reliable species protection. Our intelligent software, which flexibly adapts to the parameters of the respective wind farm, is capable of both increasing the productivity of existing as well as emerging wind turbines and taking over the complete implementation of shutdowns relevant for approval - including monitoring and documentation.

Increasing profit

Thanks to Fleximaus, the energy loss caused by species protection can be reduced by 70 % every year because the turbines are no longer shut down across the board - only when they really need to be. This increase in efficiency means that the return of investment for retrofitting Fleximaus - depending on the size of the wind farm - will be done within a few months.

Reducing costs

Facilitate monitoring, reduce expenditure: The Fleximaus software saves many manual operations. We take care of the reliable implementation as well as transparent documentation of shutdowns relevant for approval and reduce unnecessary downtimes at the same time.

Full support for maximum return: How Fleximaus works

According to your specifications, the Fleximaus measures numerous environmental parameters relevant to your personal wind farm and compares them, with the probable flight behaviour of bats or birds. Your wind turbine is only stopped if the shutdown actually serves to protect the animals: namely in periods with presumably high activity.

Our intelligent system stops the affected rotors within 20 to 60 seconds or gets them going again after a few minutes - even if there is no internet connection to the wind farm. In phases with demonstrably little or no activity, the algorithm simply continues to operate the wind turbines. In this way, you will realise maximum returns.

Of course, our optimization system keeps you informed about all steps: Wind farm operators can both track the prevailing conditions at the wind turbine in real time and understand any shutdowns at any time by using clear representations on our customer website.

Competence all around:
This is what distinguishes the Fleximaus

Legally secure

Fleximaus guarantees the legally compliant implementation of all specifications of the approval notice. Wind farm operators can easily prove compliance with the shutdown conditions - so that there is no ban due to missing or incorrect shutdowns. You will also receive a complete system description from us with all the functions of the Fleximaus - you can already use this for the approval of your wind farm to show the responsible authority how you would like to comply with the necessary operating conditions in the future.


Germany is versatile: the north and south, for example, are characterised by summers with high precipitation, while the east has a rather dry and mild climate. And because animals behave just as differently as the weather in the individual regions, we have developed an intelligent software that can respond flexibly to these location-specific conditions. Whether you operate just one wind turbine in Bavaria or several big wind farms throughout Europe - our manufacturer-independent system can be retrofitted into existing wind turbines as well as used in new wind turbines from all well-known turbine manufacturers.


Our team constantly checks the functionality of the Fleximaus: No matter whether a sensor has failed or the system is no longer connected to the wind farm - our software reports any technical malfunction, so that expert service staff can usually fix the fault immediately via remote maintenance. The system is monitored via secure and encrypted connections provided by a German data centre. For IT-security reasons, individual wind farm operators do not have access to the server managed by Fleximaus GmbH - after all, customer-specific events, stop commands or environmental data are monitored there.

Renowned manufacturers already trust the Fleximaus.

This means for you:
The warranty of the manufacturers remains intact.

All-round clever in the wind:

Return on investment & species protection work together

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

Bat protection
and wind turbines

Our solutions >>

The smart Fleximaus system adapts to the individual conditions of your new or existing wind farm and ensures reliable, economic and approval-compliant operation because Fleximaus knows to use local bat-friendly algorithms.

Birds and wind energy

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. With our automated tractor recognition, we help technical managers to reliably identify management events and to keep a record of when an event or no event has taken place. (FlexiBird)

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.
