Sustainable battery storage systems for commercial and industrial applications – with STABL Energy

Make your company fit for the future

With STABL Energy, battery storage systems for trade and industry become economically and environmentally friendly. Thanks to our patented inverter technology, conversion losses can be reduced by up to 70%, which saves energy and therefore costs and minimizes CO2 emissions. In addition, STABL Energy is the first to enable the economical, safe and uncomplicated use of so-called reconditioned second-life batteries.

Too many batteries in electric cars are disposed of or laboriously recycled at the end of their service life, although they still have up to 80% of their original capacity and great potential.

STABL Energy gives these batteries a second life. Thanks to our patented inverter technology, we can offer energy storage solutions from second-life batteries with our partners - more sustainable and cheaper than other and new systems.

It is up to you whether you choose a storage system with new or used modules. We offer both!

Sign up for the waiting list and learn more about how we can convert your company to a long-term environmentally friendly and cost-reduced energy supply.

The advantages of environmentally friendly STABL battery storage systems

Secure energy storage

We build the battery storage from low-voltage modules. This means that the system can be easily installed without special knowledge and, what is even more important, it can be maintained without risk.

Highest efficiency

Scientific studies by the Technical University of Munich shows that the STABL inverter technology is more efficient than comparable inverter systems. The losses are reduced by up to 70%.

Transparent technology

Monitor the processes in the storage – down to cell level. Check the status of your energy modules anytime, anywhere.

The advantages of STABL second-life storage

Environmentally friendly operation

With STABL second-life storage systems, you can reduce CO2 emissions – not only locally, but also on a global scale.

Best possible performance

The requirements placed on stationary systems can be met by used batteries in the same way as new cells.

Profitable efficiency

STABL second-life storage systems are up to 40% cheaper than new storage systems.

Cities & Communities

Cities & Communities

Prepare your public facilities for the future by switching to the greenest storage solution available. We make your community groundbreaking.



Never be without electricity. STABL second-life storage systems are also suitable for emergency power supply. In addition, we help you to minimize the high costs of your energy-intensive processes.



Are you a pioneer of environmentally friendly energy supply and have a solar system whose feed-in tariff is about to expire? Optimize your self-generated energy with a STABL second-life storage system and increase your own benefit from it.

Our Founders

STABL Energy emerged from research projects at the Technical University of Munich, the University of the Armed Forces in Munich and the Osnabrück University of Applied Sciences. Since the foundation in January 2019 (then still as m-Bee GmbH), we have made it our mission to help future-oriented companies and businesses to focus on environmentally conscious sustainability.
