Solar storage

With a 3 GW pipeline of solar and battery projects, Metlen is strengthening its position in Italy through new storage projects, tolling agreements and partnerships with industrial energy consumers.

A study by the Hrvoje Požar Energy Institute and the University of Zagreb finds battery storage cuts system costs by up to 15 percent, supporting payback within around ten years.

PV Guided Tours: Atmoce presents two new innovative products – a micro inverter and a low-voltage battery. The M-ELV battery operates at less than 30 volts, increasing safety for installers and simplifying day-to-day work. Intelligent energy management system connects both components. The low-voltage technology is designed to benefit private households as well as commercial users.

PV Guided Tours: Industry and commercial enterprises can reduce electricity costs in various ways using storage systems – but security is key. Luis Haya, Solution Manager Chint Power Systems, explains which features are needed to ensure security is safeguarded.

New analysis finds Croatia may require up to 1,620 MW of battery storage to support renewable expansion and shows how needs vary across different deployment scenarios.

As European balancing markets near saturation, the business model for battery storage is undergoing a fundamental shift. Securing long-term returns now demands that optimisers adopt sophisticated spot trading strategies, argues Stephan Lehrke of Second Foundation.

The domestic battery storage sector is entering a new phase, with deal activity emerging around merchant projects expected to be prioritised under the Ministry of Environment and Energy support scheme.

Flexible demand is already competing with battery storage in parts of ancillary services and capacity markets, though evidence of broader effects on wholesale price spreads remains limited, says Pexapark analyst Nicolas Briet.

Energy costs shape competitiveness in both global and local markets. As fossil and nuclear prices continue to rise, solar and wind are no longer marginal technologies but increasingly represent the smart money in power generation.

PV on Tour – The Evercore series from Solis integrates inverter, battery and energy management in a single unit, offering 100 kW power and 120 kWh capacity. The larger version delivers up to 261 kWh, paired with a hybrid inverter rated at 50 or 60 kW.

Figures from sun.store show a broad price correction in residential batteries, while commercial and industrial prices declined across both capacity ranges, with sharper drops in smaller systems.

Built on Whes hardware and proprietary software, the system is designed to scale across commercial and industrial settings, with additional applications in smaller utility environments.

As energy demands grow, flexibility and reliability become even more essential. Designed for commercial operations, agricultural businesses and larger residential buildings, the new Fronius Reserva Pro delivers both. This high-performance battery system offers impressive capacity, European cell and module manufacturing, and seamless integration into the Fronius ecosystem.

Large-scale storage systems are gaining ground across Europe, driven by growing demand for grid stabilisation and peak load shifting. Italy, Great Britain and Germany are leading the charge. Download our latest free e-paper now.

Strategically placed battery storage would unlock gigawatt hours of additional renewable feed-in and shore up Croatia's volatile midday power prices, a new study finds.

Podcast: The Energy Center from ESS Inc. in Oregon is an iron flow storage system offering 1.16 MWh of capacity and 174 kW of maximum charging power. 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 using sustainable materials such as iron, salt and water.

CEO Talk: Demand for large storage systems is surging across Europe, but delivering them involves major challenges – from permitting and financing to construction and operation. Michael Hierholzer of Rolls-Royce explains why experienced and reliable partners are key.

Hithium’s modular Power Flexsso, offered in 3.125 MWh and 6.25 MWh (four-hour) configurations, weighs under 26 tons per unit, allowing standard road transport and simplifying deployment across regions with logistical constraints.

PV Guided Tours: SAX Power offers an AC storage system that operates without a battery inverter. It is also a multi-talent – suitable for both new solar systems and retrofits. Is this storage system really as simple as the provider promises? Watch the video to find out.

HTW Berlin’s latest annual study of residential PV battery systems finds new efficiency highs among leading products, but persistent gaps between top and lower-ranked systems.

PV Guided Tours: Huawei FusionSolar is unveiling its new Luna2000 utility-scale battery storage system with a capacity of five MWh. The current 4.5 MWh systems have already received the Prime safety certificate from TÜV Rheinland.

PV Guided Tours: Fenecon presents the Industrial XL with 1.5 MW and four MWh in a new container format for large-scale projects, alongside a flexible power pack for SMEs and the updated Commercial 92 featuring an innovative split-tower design.

PV Guided Tours: The integrated Power Store sytem from Denios combines a C&I battery unit with a safety container, designed to protect against thermal runaway while enabling tailored design and fast amortisation. Watch the video to learn more.

PV on Tour: Sigenergy presents its commercial storage system, SigenStack. The modular solution incorporates AI and is paired with an external hybrid inverter delivering between 50 and 125 kilowatts, depending on configuration. As with the SigenStor residential system, SigenStack features a sophisticated safety concept.

PV Guided Tours: The system supplies three-phase backup power and utilises an intelligent EMS. The focus is clearly on safety and efficiency – including for the new, hybrid-cooled Luna2000-215kWh battery storage system for C&I. It has been awarded the highest safety certificate by TÜV Rheinland.
