An outstanding battery storage system is more than the sum of its parts. That’s why we specialise in developing innovative systems that are precisely tailored to the requirements encountered in industry and commerce, with a variety of impressive application options.

With all our products, safety, reliability and economic efficiency, not to mention a first-class installation service, take priority. We guarantee this not just by using high-quality components – such as Samsung SDI high-performance prismatic cells – but also through our unique battery control systems.

The TESVOLT Active Battery Optimizer (ABO) and the TESVOLT DynamiX Battery Optimizer (DBO) monitor and control cells’ charging and discharging processes. Combine them with the Active Power Unit (APU) and our battery monitoring solution (BatMon) to experience truly high-performance, transparent battery management.

Whether you go for the E-Series or the A-Series, the outstanding quality and performance of our storage systems are sure to impress you.

Reduced to the maximum, the storage systems of our E series offer the highest energy density with excellent value for money. The latest generation of lithium-ion batteries from Samsung SDI in combination with our Dynamix Battery Optimizer (DBO) provide maximum performance with minimal space requirements. There are virtually no limits to the industrial applications.

Discover the E-Series

With outstanding quality, long lifespan and expandability, the A series storage systems meet the highest standards for commercial or industrial usage. By using our Active Battery Optimizer, you can ensure cell-friendly balancing, a theoretical lifespan of up to 30 years with almost no loss of efficiency – which can reach 98% – with easy retrofitting of individual battery modules whenever you need more power.

Discover the A-Series

All energy flows can be recorded, controlled and monitored with our innovative TESVOLT energy management system – consisting of the TESVOLT Energy Manager and the myTESWORLD portal. By setting individual operational management strategies, you can combine a wide variety of applications and thus perfectly adapt the system to the needs of commerce and industry.
