Tesvolt- HV 70 Outdoor Lithium Storage System

Operating voltage: 627 to 930V DC

Whether to increase self-consumption or to cut peak loads, on- or off-grid to optimize diesel hybrid systems, whether in the desert or the Arctic circle – with the TESVOLT TS HV 70 storage system, TESVOLT offers a technical storage solution for any application.

It’s advanced, cost-optimized design makes for unbeatable efficiency – without sacrificing quality or performance.

It is exceptionally robust and is, therefore, well-suited to the hardest tasks. Thanks to high-quality battery cells from the automobile industry and innovative technologies, such as the Active Battery Optimizer, our TESVOLT TS HV 70 outdoor storage system is one of the most efficient and durable products on the market.

Maximum safety

Prismatic battery cells are incredibly durable, safe, and sturdy, particularly in comparison to Round cells. TESVOLT uses Samsung SDI cells and offers a capacity guarantee of 10 years on the battery modules.

Robust and durable

Thanks to the sturdy double-walled aluminum casing, the storage system offers the highest level of impact protection, IK 10. Battery cells and battery management are built to last outstanding 8,000 cycles or provide a 30-year lifespan.

Perfectly adaptable

Two different cooling concepts and additional optional features guarantee that the system can adapt perfectly to the operating conditions. This means you invest only in the features you need.

High-performance without compromise

TS HV 70 Outdoor storage systems can store energy very quickly, and rerelease it just as quickly. With a continuous power rating of 1C, the storage system optimized for professional use in commercial applications, agriculture, and industry.

Flexibility now and in the future

Our TS HV 70 Outdoor storage systems do not only offer flexible configuration options at the moment of purchase – thanks to the innovative Active Battery Optimizer technology, and the battery modules can also expand or exchanged even years later.


The TS HV 70 Outdoor storage system is designed to be completely modular, from the prismatic battery cells to the outdoor rack. It is, therefore, easily customized and extremely efficient, thanks to its long service life.



  • Charging infrastructure – solve the problems of the future and combine the applications of peak shaving, self-consumption, and grid services
  • Diesel hybrid optimization – diesel hybrid systems can be optimized for consumption with this system
  • Peak load shifting – cut your peaks in consumption and save money by reducing the size of the mains connection
  • Increase self-consumption – use more of the power you have generated
  • Ancillary services – manage frequency, active and reactive power, and balance grid fluctuations
