An industry insider for the global sale of battery storage systems
In March, TESVOLT unveiled its new high-voltage battery, which meets the latest safety standards and boasts a service life of 30 years. The Active Battery Optimizer technology developed at TESVOLT actively balances charging currents between the cells and the battery modules, enabling battery storage systems to achieve 98% efficiency.

“TESVOLT’s battery management system is a unique technology. The product is mature, fully certified and the ideal solution – as the global demand for energy storage systems is high and set to increase further in years to come. We are now setting out to open up new markets for sales outside of Europe. I am very much looking forward to this project,” says Geib.
