TESVOLT storage systems
The right solution for every situation

Power meets performance

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.
