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.

Passive
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

We efficiently optimize battery lifespan by adjusting the ratio of gross to net capacity and significantly reducing cyclic aging.
The result: a lifespan of 10 to 15 years and noticeable financial benefits.
Our various battery modules benefit from this proven concept and, thanks to our Batteryflat, come with a guaranteed lifespan of 10 years.

Complete package

Robust, flexible standardized

The Voltfang 2 from the outdoor segment comes as a complete solution with all key 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.

Thanks to our 10-year warranty with no limit on charging cycles, your system’s storage capacity is preserved in the long term – if needed, we’ll replace battery modules quickly and easily.
