Large battery storage FAQs
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 as needed—for example, to stabilize the grid or for energy trading. Storage is typically provided by lithium-ion batteries. Modern systems such as the Voltfang 3 Plus feature a modular design, intelligent control, and comprehensive monitoring.
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 3 Plus, like its predecessor, 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. Its modular design allows for flexible project sizes, ranging from individual containers to large battery farms.
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 3 Plus is available as a 20-foot container. Each DC block offers a gross capacity of 5.64 MWh and a net capacity of 5.4 MWh. The system can be expanded modularly, making it possible to implement projects in the two- and three-digit MWh range.
The Voltfang 3 Plus is designed for maximum safety and reliability in outdoor use (IP56 rating) and is certified to the most stringent international standards. These include North American safety standards (UL1973, UL9540, UL9540A, NFPA855) as well as comprehensive IEC standards for energy storage systems and electromagnetic compatibility.
The facility operates around the clock using an advanced energy management system (EMS) that detects potential faults early on. The system enables proactive maintenance and minimizes downtime. Updates, analyses, and services are provided digitally to ensure maximum availability.
The Voltfang 3 Plus is versatile: it can be used for grid stabilization and energy trading, among other things. It is suitable for applications that support the market and the grid, as well as for use as part of a sustainable energy supply.
The delivery time depends on the size of the project and individual requirements and is determined by mutual agreement. Installation requires a suitable outdoor location with sufficient space and distance from the nearest building, as well as an appropriate connection to a substation or a medium-voltage line. Voltfang will assist you with planning and coordinating the necessary requirements.
