Profitability

More performance for your money

Our green battery storage systems offer you unique advantages in terms of cost efficiency and longevity. In contrast to conventional storage systems, we guarantee 6,000 charging cycles. Thanks to our innovative double-pack approach, the service life is extended to 15-20 years – for long-lasting and sustainable energy efficiency.

Security

We guarantee lifelong reliability

Preventive
Our in-house developed Voltfang testing procedure makes it possible to make a preventive statement about the state of health, battery ageing and the expected service life of the batteries.
Testing
Voltfang testing determines both the residual capacity of the batteries and analyzes the kinetic and thermodynamic behavior in order to optimally determine the various degradation mechanisms.
Preventive
Our in-house developed Voltfang testing procedure makes it possible to make a preventive statement about the state of health, battery ageing and the expected service life of the batteries.
Active
After integration into the Voltfang storage systems, battery cells are monitored around the clock and the current and temperature are limited and controlled. Critical behavior leads to the shutdown of affected modules, which can be replaced immediately.
Monitoring
Each individual cell of the Voltfang battery storage system is monitored 24/7 by a monitoring system in cooperation with Accure, so that the operating limits can always be safely maintained.
​Battery management
Battery management ensures that the batteries are used sparingly by limiting the permissible current (C-rate), among other things.
Temperature management
To avoid possible overheating, all Voltfang battery storage systems are equipped with a cooling unit.
Shutdown & replacement
Should critical battery behavior occur despite the precautionary measures, the corresponding modules are switched off immediately and replaced if necessary.

Our fire protection measures also help to ensure the safety of your battery storage systems. Our experienced experts will support you with the long-term secure installation of your commercial storage system.
Installation site
The installation location of the electricity storage system is essential for safe operation. This should be dry and not exposed to extreme temperatures, and should also be protected by precautions such as fire doors in the event of danger.
Fireproof slide-in units
A further precaution of the battery storage system is the fireproof inserts, which prevent further spread in the unlikely event of a module fire (propagation).

Longevity guarantee

Maximum performance

Our double-pack approach efficiently optimizes battery life by adjusting the ratio between gross and net capacity and significantly reducing cyclical ageing. This results in significantly longer battery life and financial benefits. Our various battery modules benefit from this proven concept and enable a guaranteed service life of at least 10 years and 6,000 cycles.

The double-pack approach allows us to operate the battery in the lower voltage range, which leads to a noticeable reduction in cyclical ageing (lithium plating), thus ensuring a sustainable, safer and economically attractive solution for batteries.

Complete package

Robust, flexible standardized

The new Voltfang 2 comes as a complete solution for the outdoor segment with all the important components. Quick and easy to install, it can withstand extreme conditions from -20 to +50 °C. Its doubled capacity with the same space requirement as the previous model enables more efficient energy storage and a shorter amortization period.

Generation 2 of our battery system offers even more performance. Our modular system uses high-quality, requalified electric car batteries and enables quick and easy installation thanks to standardized plug-in units.

Maximum security: Our 24/7 service monitors and maintains your system at cell level.

Seamless integration of a wide range of applications into the Voltfang EMS – for maximum efficiency through optimal storage utilization, with and without PV systems.

With our 10-year guarantee, we ensure that the storage capacity of your system is maintained and replace battery modules if necessary.
