Intersolar: TESVOLT presents new megawatt container storage system TPS
Wittenberg, 10 May 2017 – Storage system manufacturer TESVOLT is set to unveil its new TESVOLT Power Storage (TPS) lithium battery storage container at Intersolar 2017. The system employs a newly developed container module which offers highly flexible installation in both indoor and outdoor environments, and also protects the storage unit effectively from external influences. A service life of 30 years and 8,000 charge cycles makes investment in the new battery storage system particularly worthwhile for industrial applications.
Low storage costs and great flexibility benefit trade and industry
“The TESVOLT Power Storage system allows us to ensure a secure power supply for major consumers all the way from the tropics to Alaska,” states Daniel Hannemann, Managing Director of TESVOLT. The containers are insulated and air conditioned, enabling them to provide constant environmental conditions in temperatures ranging from -40° to +55° Celsius. As a result, the storage systems no longer need to be installed in closed, air-conditioned rooms, and they can achieve consistently high performance levels even in challenging environments such as factories, barns or the open outdoors.
Thanks to their sturdy design, the containers can be transported in their entirety either by road or sea. Standard ISO container sizes of 20ft, 40ft and 45ft are available. Once at the installation site, all that remains is to connect the unit to a Sunny Central Storage System from SMA Technology AG, which can also be supplied as a container module.
Energy payback time of 4 to 6 years in Europe
“The TESVOLT Power Storage system is our solution for all commercial and industrial operations where storage systems of 0.5 MW and above are of interest, but for which issues of cost or installation have been a big concern until now. Enormously high power density, guaranteed charge cycles, and a simple, standardised construction make it one of the most cost-effective systems for megawatt applications on the market,” states Hannemann. With market prices for peak-load power currently ranging from 80 to 140 euros per kW, and remuneration for supplying operating reserves commanding up to 160 euros per kW, such systems are extremely worthwhile investments and achieve energy payback times of 4 to 6 years in the European market.
What is more, a discharge rate of 1C makes the TPS suitable for both on- and off-grid applications such as primary operating reserves, peak load capping, ramp rate control and load levelling, as well as for use in hybrid systems.
Outstanding performance and long service life
“We use prismatic cells from Samsung SDI which are extremely durable and safe. By combining these with our Active Battery Optimizer, which individually balances the state of charge of each and every cell, we are able to guarantee the high rate of charge cycles.” In addition, this Active Battery Optimizer allows the battery modules to be exchanged or expanded, even years later, adds Simon Schandert, Director of Engineering at TESVOLT. “As a result, the service life has a critical impact on the economic viability of all business models.”
As part of the Intersolar Europe trade fair in Munich, TESVOLT will be showcasing its products at the energy storage exhibition ees from 31 May to 2 June 2017.

Tesvolt specialises in commercial battery storage systems. The innovative company from Lutherstadt Wittenberg produces storage systems with state-of-the-art prismatic lithium battery cells from Samsung SDI, based on nickel manganese cobalt oxide. Tesvolt storage systems function just as well at low voltage as at high voltage, and can be connected to all energy producers: sun, wind, water, biogas and combined heat and power – on-grid and off-grid. All storage systems are produced at Tesvolt’s manufacturing facility in Germany.
In 2018, Tesvolt was awarded the German Entrepreneur Award. In the same year, Tesvolt received the "The smarter E award" in the "Outstanding projects" category for the off-grid power supply of an avocado farm in southwestern Australia.
