Bulgarian energy storage manufacturer IPS has released a new utility scale battery energy storage system (BESS) with a rated capacity of 8.1 MWh and integrated 4 MW inverters. The X-BESS 8 system is installed in a 

space equivalent to a 20 foot container and uses liquid cooling technology.CEO Alexander Langlov stated, "In terms of capital expenditures, a compact modular architecture enables easy customization and future oriented expansion, while significantly reducing system balancing (BOS), transportation,

and installation costs. In terms of operating expenses, all key components adopt a distributed design to ensure that the system is easy to maintain and runs reliably throughout its entire lifecycle, avoiding single point

of failure for the entire system. ”

The new battery energy storage system (BESS) uses 314 Ah lithium iron phosphate (LFP) batteries with a reported lifespan of 12000 cycles. On the AC output side, its maximum output current is 2890 A and maximum

output power is 4 MVA. According to the manufacturer, it adopts a liquid cooled three-level inverter topology, with an efficiency of up to 99.5%.

The design of X-BESS 8 complies with IEC 61000, IEC 62619, IEC 62477, EN 50549, UL 1741, and CE standards. Its operating temperature ranges from -40 ° C to 70 ° C. It has 12 operating modes, including grid 

support, start-up, and isolated grid operation.

The system adopts segmented delivery - lightweight, less than 8 tons, and does not require specialized heavy lifting equipment for transportation or installation. Each module is fully plug and play and equipped with 

standardized electromechanical interfaces, ensuring fast and low complexity on-site integration.

The EXERON X-BESS series is currently producing 5MWh and 6.5MWh models.

IPS independently designs and manufactures all system components except for LFP batteries, including inverters, thermal management systems, battery modules, battery packs, and Battery Energy Storage System 

(BESS) enclosures. It is crucial that the development and maintenance of all control software and embedded firmware strictly adhere to the EU cybersecurity framework.

In order to meet the rapidly growing demand for energy storage solutions, IPS plans to open its next automated manufacturing plant in Sofia, Bulgaria in June 2025. The annual production capacity of the factory

 is 1.5 gigawatt hours, and it is expected to expand to 3 gigawatt hours by the end of 2025.
