Solar storage

As Europe’s strained energy grid puts business growth at risk, innovative companies are seizing the moment, as Emmanuel Trivin, Managing Director Continental Europe at Wewise, explains.

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.

Spain’s solar boom is accelerating, making storage essential for grid stability. Cegasa Energía CEO Iñigo Atutxa explains how innovation, modularity and local manufacturing are driving flexible, resilient energy systems across Europe.

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 charge power. Housed in a single container, the modular unit suits 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 like 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.

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.

Robert von Wahl of Sungrow outlines key C&I storage applications, identifies the main challenges for installers and introduces new products aimed at evolving market needs.

Haier Energy presents a modular high-voltage storage system, while OBO, Kostal and Mersen introduce fresh PV solutions for mounting, inverters and fuses. These are this week’s standout products.

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.

The Pradera Larga project in Central Chile has secured environmental approval and will combine 84 MW solar PV with a 90 MW battery system, representing a total investment of around US$150 million.

After months of falling prices, November data from sun.store show a sharp turnaround: premiums are rising again, signalling a potential tightening of supply as the year-end approaches.

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.

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.

Aimed at homes and small businesses, the E-Tower HV combines a 4–15 kW hybrid inverter with 4.8–28.8 kWh modular storage and sub-ten-millisecond backup switchover.

The battery division of Trina Solar has signed its first project in Greece with PPC Renewables, delivering a 50 MW / 200 MWh system to be installed in Western Macedonia.

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.

Austrian developer Toki Power has acquired a 150 MW / 300 MWh battery storage project in Romania that will operate independently to provide grid balancing services.

The move reflects growing investor confidence in the Greek and Cypriot storage markets, supported by favourable regulation and a track record of government-led tenders.

PV Guided Tours: Intelligent systems are replacing standalone components and AI now manages storage systems, wall boxes and energy flows to make the most of solar power. It’s not science fiction, it’s already here. Still sceptical? Prepare to be surprised!

The utility-scale platform offers integrated DC/AC optimisation, robust diagnostics and a compact design, cutting footprint and streamlining installation even for large storage projects.

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.

Rising demand for grid stability, price volatility and lower technology costs are giving battery storage fresh momentum, as highlighted at a recent investors’ summit in Berlin.

A new joint venture from Metlen and Karatzis will deliver a €170 million utility-scale battery system in Thessaly, with completion targeted for Q2 2026.

The Primo unit from SAX Power connects directly to a secured socket, eliminating the need for a battery inverter. Project manager Reinhard Birmuske explains the straightforward installation of this versatile system.

CEO Talk: The market for home storage is sluggish, while C&I and large-scale storage are gradually gaining ground. To boost sales, the right strategy is essential. The key question remains: What factors determine success in this market? Franz-Josef Feilmeier, CEO of Fenecon explains.
