Storage system manufacturer TESVOLT plans to unveil its new lithium battery storage container at Intersolar 2017 (Munich, 31 May to 2 June 2017).
The TESVOLT Power Storage (TPS) employs a new container module which offers highly flexible installation inside “challenging environments” such as factories and barns or outdoors, and also protects the storage unit from external influences.
The containers are insulated and air-conditioned, enabling them to provide constant environmental conditions in temperatures ranging from -40°C to +55°C – or, as managing director Daniel Hannemann says, “all the way from the tropics to Alaska”.
The German manufacturer says the units, which use prismatic cells from Samsung SDI, have a service life of 30 years and 8,000 charge cycles.
The containers can be transported 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.
“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,” said Hannemann. “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.”
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, Hannemann believes such systems can achieve energy payback times of four to six years in the European market.
