We find out how Ampace is positioning itself in this environment, the role Europe plays for the company, and which advances and technologies are set to shape the market next.

As global battery storage grows towards 500–700 GWh by 2030, ACCURE’s Valentin Lorscheid argues that reactive operations and single-vendor monitoring are eroding returns, and explains how operators can get ahead.

From 18 February 2027, every industrial battery above 2 kWh sold in the EU needs a digital passport. Together with Minespider, the Czech manufacturer is linking every system it builds to a permanent digital record.

PV Guided Tours: Atmoce is introducing a 25-year warranty on its residential storage system and unveiling intelligent module-level energy management that supports automated snow clearing of solar panels. On the storage side, the portfolio is being expanded with the C&I BattBank, the first AC-coupled, stackable commercial storage system designed for low-voltage operation.

Global battery storage capacity is set to nearly triple by 2030, and operators are already drowning in alarms. Valentin Lorscheid of ACCURE explains how to get ahead of problems, and why independent data matters.

Eurelectric’s Power Barometer 2026 finds that clean electricity cushioned Europe from a fresh fossil-fuel shock this year, yet storage build-out is still falling well short of the pace needed to keep the system stable through 2030.

Commissioned by Fluence, the study finds flexible capacity from a battery costs $371 million over 25 years in Texas – under a third of the price of gas and a sixth of diesel.

Podcast: The Energy Center from Oregon-based ESS Inc. is an iron flow storage system with 1.16 MWh of capacity and a maximum charging power of 174 kW. Housed in a single container, the modular unit is designed for a range of commercial and grid applications. Alan Greenshields, Director EMEA at ESS, discusses long-duration storage and the role of redox flow technology based on sustainable materials such as iron, salt and water.

PV Guided Tours: Homes are increasingly becoming energy producers. Sector coupling within the building is growing in importance and even electric vehicles are now part of the picture. Gregor Kuschmann and Robert Pawlik of Solarwatt explain which components and solutions make energy independence possible and how buildings are playing a new role in the energy market.

EDENenergy delivered its first 70 kWh commercial system in mid-October. Of the 350 used batteries tested to date, many still showed over 90 percent health, beating the start-up’s 80 percent forecast by a wide margin.

Tesvolt opens energy trading to smaller businesses and Solarcube turns outdoor living space into a power plant. Rooftech keeps birds off module edges, while Mova offers home storage up to 9.6 kWh.

Danish storage specialist Emaldo and German investor KKI plan to clear the financing and approval hurdles that hold companies back, with a first installation in the Nordics before the end of 2026.

The Lumegret A2000 solar energy system combines a microinverter, battery and charge controller in one unit, while the B2000G expansion battery lets owners add capacity as their needs change.

PV Guided Tours: HYXI is showing off its newly unveiled Muse AI-Native Energy OS, which transforms energy use from passive backup into active, learning intelligence. Highlights include the Aura all-in-one storage, the AC-coupled Halo micro-storage system and the liquid-cooled Atlas C&I unit.

As manufacturers bypass distributors and sell C&I storage directly to installers and EPCs, buyers must establish who handles integration, commissioning and repairs. Removing a distributor does not remove the work, says market expert Gerard Scheper.

Feathered visitors will find little comfort on module edges fitted with the new Birdblocker Topguard, a row of steel pins that clips on without drilling and is now available in German-speaking countries.

Premium Solardesign has built its new patio canopy around bifacial glass-glass modules up to 4 m long, developed specifically for the product and mounted in a cubic aluminium frame.

CEO Talk: Growing demand for large-scale storage systems is working in favour of European suppliers. Safety and security are becoming increasingly important. What role does service play, from commissioning through the entire lifespan of the storage system? Fenecon's CEO shares his view.

Commercial battery storage combined with trading software from Tesvolt Energy puts flexibility trading within reach of small and medium-sized companies.

CEO Talk: What does the future of energy storage in Europe look like? Safer, smarter and more connected, from commercial rooftops to utility-scale projects. AlphaESS shows how a single open system can link all of these applications. Find out more about the company’s strategy.

PV Guided Tours: The three-phase Powerwall 3P battery delivers 15.4 kW of AC output and adapts flexibly to demand. Behind it all sits the Tesla Home energy manager, which links the battery, PV system, EV and heat pump – all optimised by AI software.

C&I storage with built-in backup from Hoymiles, AI-supported home backup from Sigenstor Neo, 261 kWh cabinets from Clou and Midea and more capacity from Solarwatt’s Battery Vision 2.0, all new this week.

Lithium-ion storage carries real risks of thermal runaway, fire and explosion. Certified technical containers can shield installations from external hazards and ease the route through building approval processes.

Capacity, cycle life and price dominate most battery comparisons. Randy Levine of SolarClarity.co argues that the household’s electricity tariff decides whether storage is worth the money.
