Large-scale battery storage for market and grid applications

A large-scale battery storage system is a stationary energy storage system with a capacity in the megawatt hour range. It stores electrical energy that can be released again when required – for example to stabilize the grid or for energy trading. It is usually stored using lithium-ion batteries. Modern systems such as the Voltfang 2 Plus Grid-Scale have a modular design, intelligent control and comprehensive monitoring of each individual battery cell.

Large-scale battery storage systems are suitable for industrial companies, municipal utilities, energy suppliers, charging park operators and commercial enterprises with high electricity consumption. Typical applications include peak shaving, security of supply, provision of primary and secondary control power, grid stabilization and participation in the electricity market.

The Voltfang 2 Plus Grid-Scale offers high cost-effectiveness, maximum reliability through redundancy, flexible scalability, efficient climate control, comprehensive remote monitoring and a long service life. By using requalified electric car batteries from German manufacturers, the system is particularly sustainable and conserves resources. The modular design allows flexible project sizes from individual containers to large battery parks.

As every project has individual requirements and framework conditions, it is not possible to provide exact prices across the board. After a free electricity analysis and request for quotation, Voltfang offers you non-binding price information tailored to your project. This will give you a reliable estimate of the cost-effectiveness and amortization for your company.

After your inquiry, you first fill out a non-binding quotation form. Your project will then be individually analyzed to determine the optimum storage tank size and design. The requirements and details are agreed in a personal consultation. Voltfang accompanies you from planning, delivery and installation through to commissioning and subsequent operational management.

The Voltfang 2 Plus Grid-Scale is available as a 20 or 40-foot container. It offers a gross capacity of up to 6.35 MWh per container and a usable capacity (depending on the unloading depth) of up to 5.72 MWh. The rated output is up to 2.6 MW, depending on the version. The system can be expanded on a modular basis so that projects in the double-digit MWh range can be realized.

The Voltfang 2 Plus Grid-Scale uses requalified lithium-ion batteries (NMC) from European automotive applications. The cells meet the automotive standard and offer maximum efficiency (up to 98.26% charge/discharge efficiency) as well as an expected service life of 15-20 years. All components such as inverters, air conditioning and protection technology are designed for continuous operation and high reliability.

You receive a 5-year warranty on the system and capacity as standard. With the optional Batteryflat service, the warranty can be extended to 10 years and up to 8,000 charging cycles – regardless of usage. You benefit from 24/7 monitoring, remote maintenance and proactive service from the Voltfang team over the entire operating period.

Voltfang produces its battery storage systems in Aachen (NRW) in Germany. Production is carried out to the highest quality standards. The battery modules consist of tested and requalified electric car batteries from German automotive production, which means that no additional resources are required for new battery cells.

The system is CE and UN38.3 certified, meets the IP56 protection class and is designed for outdoor use. Comprehensive monitoring at cell level and an intelligent battery management system ensure maximum safety. In addition, there is a multi-level redundancy concept to ensure uninterrupted power supply.

It operates around the clock with an advanced energy management system (EMS) that monitors each individual cell and detects potential faults at an early stage. The system enables proactive maintenance and minimizes downtime. Updates, analyses and services are provided digitally to ensure maximum availability.

The Voltfang 2 Plus-Grid Scale can be used flexibly: for grid stabilization, for energy trading or for protection against power outages. It is suitable for market and grid-supporting applications as well as a component of a sustainable energy supply.

The delivery time depends on the size of the project and individual requirements and is determined after consultation. A prerequisite for the installation is a suitable outdoor location with sufficient space (e.g. for a 20 or 40-foot container, 5 meters from the nearest building) and a suitable connection to a transformer station or a medium-voltage line. Voltfang supports you in planning and coordinating the necessary requirements.
