VENSYS STORAGE TECHNOLOGY

The VENSYS VENSTORE and VENSYS VENSTORE Lion battery storage ensure reliable electricity input from different energy sources and provide the stored energy at exactly the time when needed. The storing of electrical energy allows you to become more independent of increasing electricity prices.

VENSTORE storage solutions are unique thanks to their modular structure and the associated, nearly limitless scalability. VENSTORE storage systems and VENSYS VENCON inverters guarantee high power density and versatility. Equipped with proven technology and innovative network management capabilities, this system solution is available in both, an indoor and outdoor cabinet.

VENSYS VENSTORE LION

The innovative VENSYS VENSTORE LION storage technology is the final step towards independent power supply. Based on the most progressive lithium-ion technology, characterised by multi-megawatt performance reserves and a higher temperature range, the VENSTORE LION has a multitude of application options. VENSYS storage solutions stand for intelligent and future-proof technology on a global standard.

The VENSTORE Lion storage system is available in an indoor and outdoor cabinet. Thanks to its multiple application cases this system provided a high degree of flexibility.

THE HIGHLIGHTS: POWERFUL

  • Modular design and innovative IT management provide high scalability
  • Compact outdoor cabinet for flexibility and low overhead costs
  • Excellent safety standard thanks to protective features and optimal monitoring
  • Innovative Battery Management System
  • Cell technology to highest industry standards
  • Capacities up to 115k kWh per cabinet
  • Optimised for wide climate range
  • Connecting to VENSYS systems without additional inverters

VENSTORE LION Application cases

SELF-CONSUMPTION OPTIMISATION

The amount of energy gained from volatile energy producers is often not in line with own energy needs. With VENSTORE Lion, excess energy can be stored and provided at a different point in time. Supply optimisations can also be enhanced.

FEED-IN LIMITATION

If the system performance of the generating facilities happens to be higher than the power supply, the VENSTORE storage solution can store the excess energy and release it at a desired point in time.

POWER SUPPLY NETWORK

Load peaks in the supply network can be compensated for with this solution, thereby avoiding a network expansion and minimising transfer loads from medium- voltage transformers.

FREQUENCY CONTROL

The VENCON Wechselrichterfamilie can react quickly to either over-frequency or under-frequency, so that the VENSYS system solution can support the grid frequency.

PROVISION OF ENERGY CONTROL

In order to trap excess production, the network storage solution VENSTORE can temporarily store this energy. In so doing, no regenerative power generation must be reduced or switched off completely. Thus, the proportion of environmentally friendly electricity can be increased in the network without necessity to set up additional generating plants.

*Depends on the calculated limit of the BMS. The BMS will reduce the performance with an increase of the resistance of the cell. This could happen at e.g. too low or too high temperature. 

The All-rounder among the Converters

Bi-directional and specially engineered for peak shaving, optimization of internal consumption, emergency power, Microgrid and much more.

Modular: Expandability in steps of 150 kW means total power can be reached for all sizes, with several systems being linked via a DC bus.

Versatile Up to three completely diffe­rent DC sources with 120 kW output each can be operated in a broad voltage range.

Easy to maintain: The modular design, air cooling and the ability to control the system remotely (Web Interface) make sure VENCON requires only a minimum amount of maintenance.

Flexible Thanks to its compact design VENCON is suitable for use in any location.
