One of the highlights is always walking the show floor across the many packed halls and seeing equipment and solutions from a diverse range of providers and technology types at all scales.

Below is a short preview rounding up some of the releases has seen ahead of the event.

While we can only bring you a very small sample of the products that will be on show from leading providers to interesting startups, we hope it will give you a taste of some of the trends and tech you might find at the exhibition. 

SMA: Central PCS/inverter for solar, storage and hydrogen

Solar PV inverter company SMA Solar Technology has been increasing its presence in the energy storage space for some time and new products it will bring to the show include a new version of its Sunny Island battery inverter and a home energy management solution.

Perhaps of most interest to readers however, will be Sunny Central Flex, a large-scale power conversion solution designed to be as at home in a standalone battery energy storage system (BESS) or hydrogen electrolysis project as it is at a solar farm.

The product comes with fully integrated AC-DC and DC-DC converter, with energy storage retrofit optionality, medium-voltage (MV) transformer and switchgear, as well as grid-forming capabilities.

Sunny Central Flex comes in a 40-foot tall cube configuration with a CSC-certified transportation frame. The company claimed it enables a wide range of storage applications, from frequency containment reserve (FCR) to new grid services such as black start capability and inertia.

Sunny Central Flex has been nominated for the prestigious ees Award at the show, and SMA will be unveiling the product on 19 June.

Ampace presents ‘innovative’ thermal management technology

Also holding an unveiling at ees Europe on 19 June will be Ampace, manufacturer of distributed energy storage systems formed as a joint venture between CATL and ATL.

Ampace said a range of lithium-ion (Li-ion) products featuring an innovative full range temperature control technology which requires no auxiliary power consumption for cooling, and a battery cell which is capable of 15,000 cycles, making it ideal for pairing solar PV with energy storage.

The company’s products include residential, commercial and industrial (C&I) and portable and UPS battery solutions. According to Shenzhen Gaogong Industry Research (GGII), it was the leader in exporting residential battery systems from China overseas, representing about 30% market share.

Its Kunlun Battery Cell 2.0 utilises a new technology, called GT40, which comprises “new” cathode and anode materials, new electrolyte materials and a double-headed battery tab structure.

Kunlun powers Ampace’s C&I range, and in combination with the company’s thermal management system, which it claimed is a “breakthrough” innovation, customers can enjoy improved operation and lower lifetime costs.

Voltfang’s C&I energy storage with European automotive batteries

German company Voltfang will be launching the next generation of its battery storage system for C&I applications, equipped with second life electric vehicle (EV) batteries.

Voltfang 2 is an integrated system which is designed to be installed as a turnkey solution. It offers 100% more capacity than its predecessor, and is lower cost. Like Ampace, Voltfang claimed its product’s thermal management technology is a selling point, enabling the system to be used in ambient temperatures of -20 to 50C, and temperature optimisation can extend the cycle life of the system’s battery modules to a guaranteed 10-year, or 6,000 cycle lifetime.

“Our system is specifically designed for outdoor use to provide our customers with a seamless process. Installation requirements such as a fire room or expensive fire insurance are no longer necessary,” CTO and founder Afshin Doostdar said, adding that Voltfang 2 is designed to be installed in as little as two hours.

Each unit comes with 180kWh usable energy storage capacity, with batteries sourced from European automotive OEMs.

Hyperstrong brings 5MWh+ containerised BESS

China-headquartered battery energy storage system (BESS) manufacturer and integrator Hyperstrong will showcase a range of full-stack energy storage solutions for applications ranging from large utility-scale to C&I and EV charging with integrated energy storage.

Joining the growing ranks of global BESS providers with a solution packing 5MWh or more of capacity into a 20-foot standard container configuration, Hyperstrong will be presenting its HyperBlock III for utility-scale.

HyperBlock III is equipped with large format 314Ah cells, and battery packs and power conversion system (PCS) components are integrated into one cabinet, featuring liquid-cooled thermal management.

Hyperstrong claims cell, electrical and structural safety in the product are monitored with “intelligent” sensor technology, while digital modelling is used to provide AI-driven analysis of cells through their entire lifecycle, both of which are features that contribute to a high safety standard.

CLOU’s ‘unique’ Engineering and Procurement Package

CLOU, another China-headquartered manufacturer and integrator, will be returning for its third appearance at the Munich event next week.

This time out, its offerings are led by the CLOU Engineering and Procurement Package (EP Package), which the company claims is a “unique” end-to-end turnkey solution including DC block, PCS, MV transformers, switchgear, EMS, SCADA, and operations and maintenance (O&M) services—the entire BESS value chain, CLOU said.

EP Package also covers site-level system sizing, electrical and communications design, financial analysis and Long-term Service Agreements (LTSAs).

CLOU will also be displaying its latest, higher energy density BESS unit, Aqua-C2 which among other things is claimed to be capable of withstanding extreme weather environments, and previewing Aqua-C2.6, a 5MWh+, 20-foot containerised BESS solution, compatible with either string PCS or DC-DC converter. will be attending and reporting from ees Europe, which takes place next week, 19-21 June 2024 at Messe München, Munich, Germany.
