IPS has developed an 8.1 MWH Utility scale battery energy storage system (BESS) in a 20-foot container with an integrated 4 MW inverter. The Bulgarian manufacturer says that it wants to meet the growing demand for efficient, large -scale energy storage solutions.
IPS-in Bulgaria established storage manufacturer IPS has released a new Bess at the utility company with a nominal capacity of 8.1 MWh and an integrated 4 MW. The X-BESS 8 system is housed in a 20-foot container footprint equivalent and has liquid cooling.
“On the Capex side, the compact, modular architecture may ensure difficult adjustment and future-proof scale, while the costs for the balance of the system (forest), transport and installation are considerably reduced,” said IPS CEO Alexander Rangelov. “On the OPEX side, easy maintenance and reliable operation are guaranteed during the full lifespan of the system via a distributed design of all critical components, without any failure point for the general system.”
The new Bess uses lithium-iron phosphate (LFP) batteries and is said to have a lifetime of 12,000 cycles. On the AC output side it has a maximum output current of 2,890 A and a maximum output power of 4 MVA. It uses a liquid -cooled, three levels of inverter topology that, according to the manufacturer, achieves 99.5% efficiency.
The X-Bess 8 is designed in accordance with IEC 61000, IEC 62619, IEC 62477, EN 50549, UL 1741 and CE standards. The operating temperature is between -40 ° C to 70 C. It has 12 operating modes, including grid support, black start and operation in an insulated network.
“The system is supplied in segments light weight, sub-8-ton blocks that do not require specialized heavy equipment for transport or installation,” the company said. “Each block is completely plug-and-play, with standardized mechanical and electric interfaces to guarantee rapid integration with low complexity.”
