Commeo HV System, bipolar

Developed as modular battery storage, the Commeo HV battery systems offer unique flexibility in the high-voltage range and, thanks to the compact design of the energy storage blocks, take up less space than systems with a comparable performance level.

With the new ccuHV-B bipolar control unit as an additional component for the Commeo HV system, Commeo is now the only lithium-ion battery system supplier that offers the option of simultaneously supplying a positive and a negative voltage to a zero-point reference potential (recognisable on a total of three battery connections with zero point tapping, in contrast to two battery connections – plus / minus – in unipolar systems). With this concept, a large part of the necessary transformation work for the provision of AC voltage from the internal DC voltage of the energy storage blocks is provided by means of intelligent system design via the control unit of the energy storage system. This drastically reduces the necessary degree of complexity on the part of the inverter/converter, which for the first time makes it possible to use a three-level converter to achieve an economic advantage of 20 to 30% when providing energy from a lithium-ion storage device compared to applications with a normal, unipolar battery converter.

Made in Germany: As a Li-ion battery manufacturer in Germany, Commeo offers turnkey energy storage solutions from a single source – from the development and production of individual storage blocks to the construction of entire energy storage systems. Feedback and requirements from our customers can thus flow directly into the design and further development of the products.

What added value does the Commeo battery storage offer?

The added value lies in the fact that you do not need any separate battery rooms due to the high level of security and the high performance of our energy storage systems with a small space requirement; our systems can often be set up directly where their energy is needed.
In addition, our energy storage professionals offer a full service. Together with you and your customers, they have developed a complete concept for the effective, future-proof design of the energy storage system.

Why are Commeo battery systems safe?

When handled correctly, Commeo battery systems are completely safe.
Commeo has implemented a multi-level, redundant security system in the energy storage blocks and systems. Due to

  • to a robust aluminium housing
  • a relay
  • safety fuses
  • an intelligent battery management system (BMS) that Commeo developed itself and which monitors temperature, voltage and other safety-relevant parameters and counteracts them if necessary
  • control unit

and other features relevant to safety, Commeo products are state-of-the-art.

What benefits can you expect from Commeo?

Development expertise

From the energy storage block to the complete energy storage system and control unit, all the components of battery storage have been developed by Commeo. The Commeo energy storage system has been specially developed in Germany in line with the highest European safety and quality standards.


Thanks to regional suppliers and complete freedom in deciding on the components used, we are fully independent of global political and economic developments.

Connection suitability

We provide our partners with an innovative developer interface so that external peripherals can be connected to our battery systems. In this way, we ensure that current and future converters, chargers, controllers etc. – plus protocols of data formats – can be used with innovative energy storage solutions.
