Tesvolt TS

Tesvolt TS


Whether it be emergency power, a stand-alone power system or to cut peak loads, on- or off-grid, the TS system from TESVOLT offers a technical storage solution for any application.


The TS system is not only flexible, with a size and output that can be adapted to suit any need, it is also one of the most advanced and efficient storage systems. It is extremely 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 TS storage system is one of the most efficient and durable products on the market.

Maximum safety

Prismatic battery cells are incredibly durable, safe and powerful – particularly in comparison to round cells. TESVOLT uses cells from Samsung SDI and offers a 10-year performance warranty on the entire storage system.

Long lifespan

The lifespan of a battery has a huge impact on its economic efficiency. The TS storage system features outstanding performance: all components are designed to last 8,000 cycles and offer a 30-year lifespan.

High-performance without compromise

TS storage systems can store energy very quickly, and release it again just as quickly. With a continuous power rating of 1C – and even 4C for short periods – the storage system is optimized for professional use in commercial applications, agriculture and industry.

Flexibility now and in the future

TS storage systems do not only offer flexible configuration options at the moment of purchase – thanks to the innovative Active Battery Optimizer technology, the capacity can also be expanded years later.
