The installation of Tesvolt’s commercial lithium ion system is as easy as a box
The German company Tesvolt is specialized in commercial energy storage systems based on lithium ion technology and solar inverters of SMA. The system’s storage capacity ranges from ten to 120 kilowatt hours. The systems Tesvolt Li are pre-fabricated in a box or some boxes – or a container station. It is ready for the connection to the electrical grid and the local power system to serve in it.
Just a screwdriver and a spanner
Tesvolt’s customers themselves, i.e. the local technicians, only do the work of adapting the length of cables to the circumstances on site. The entire unit can be installed using only a screwdriver and a spanner. It can be moved using a pallet jack or a forklift, or in case of inaccessible places or basements, it can be completely disassembled and put together again on site. Disassembling a storage unit will take two technicians about half a day. The Li-60 weighs about a ton and the smaller Li-10 unit 150 kilograms. Because the steel frame of the battery cabinet is very sturdy, it is possible to stack a number of Li-10s on top of each other.
48 volts minimize the risks
The battery blocks run on 48 volts. “The low voltage brings the advantage that the technician can also install the battery blocks himself,” Schandert sais. “He can start out with 30 kilowatts and later add another 30 kilowatts. At higher voltages, special training would be required to install and maintain the storage units. Many technicians like to wire the cabinets themselves in order to fit them exactly to their customers’ needs.” (IR/HS)
