LONGi successfully launches integrated solar and storage portfolio in the DACH region amid Germany’s changing energy market

LONGi ONE addresses growing demand for integrated, reliable, and intelligently managed storage systems across Germany and Europe.

LONGi officially introduced its LONGi ONE commercial and industrial storage portfolio to the DACH market during an exclusive launch event in Germany attended by around 60 customers, EPCs, distributors, and commercial and industrial energy stakeholders. The event marked a significant milestone in LONGi’s transition toward integrated solar and storage energy systems as renewable energy infrastructure becomes increasingly interconnected and intelligent.

Held in the presence of key partners from across the German-speaking solar industry, the event also focused on the broader transformation currently reshaping the European energy landscape. Discussions centered around increasing grid instability, electricity price volatility, growing renewable penetration, and the rising need for intelligent energy storage infrastructure across Europe.

Alongside the product presentations, the event also focused on strategic market developments and the future role of storage within commercial and industrial energy systems.

“We are seeing a fundamental shift in how energy systems operate across Europe,” said Jia Chao, President LONGi Solar (DG) in Europe. “Storage is becoming an operational requirement for many commercial and industrial applications. Customers are looking for systems that combine reliability, intelligent control, and long-term operational stability.”

Storage adoption in the German C&I sector remains in an early phase

The event featured keynote presentations from influential voices in the German energy sector and storage industry analysis. Among them was Professor Dr. Volker Quaschning from HTW Berlin, one of Germany’s most recognized experts on renewable energy systems and the Energiewende. Quaschning addressed the accelerating transformation of Europe’s electricity markets and the growing role of storage technologies in stabilizing renewable-based energy systems.

Another keynote speaker was Markus A.W. Hoehner, CEO of EUPD Research, one of Europe’s leading renewable energy market intelligence and certification organizations. Hoehner presented current developments within the European and German storage markets and highlighted the significant untapped growth potential in the commercial and industrial segment.

Germany’s commercial and industrial storage market continues to operate at a relatively early stage of adoption, despite growing demand for energy autonomy, backup capability, peak load management, and grid stabilization. This development is expected to create substantial opportunities for EPCs, installers, and industrial energy operators in the coming years.

“The commercial and industrial storage market in Germany is still at a very early stage compared with the residential and utility-scale segments, where storage has already become an established part of modern energy infrastructure. In the C&I sector, many companies are still evaluating how storage can be integrated safely, reliably, and economically into existing operations. Safety plays an especially important role here. Concerns around fire protection and operational reliability remain one of the key barriers for many industrial customers. The LONGi ONE storage systems are based on our patented and unique predictive cell-level safety monitoring and integrated system control. They can help build the confidence needed for broader market adoption. They can help build the confidence needed for broader market adoption. At the same time, a very large installed base of existing commercial and industrial PV systems across Germany creates strong retrofit potential, while energy trading, grid interaction, and intelligent load management are only beginning to open up new economic opportunities for the sector,” said Gerald Müller, Vice General Manager DACH at LONGi Solar (DG).

Coordinated energy systems become the next phase of the energy transition

Europe’s rapidly changing energy market formed a central backdrop to LONGi’s expansion into storage. Increasingly volatile electricity markets, growing grid instability, and rising operational complexity across commercial and industrial energy systems are placing new demands on storage infrastructure.

The launch also highlighted LONGi’s transition from a photovoltaic manufacturer into an integrated solar and storage system provider. The LONGi ONE platform combines inhouse-developed EMS, BMS, PCS, thermal management, and iCCS predictive safety technology within one coordinated architecture developed for system-level control and operational stability.

All major components communicate continuously with each other, enabling predictive safety monitoring, intelligent energy management, and stable long-term operation across dynamic energy environments.
“Future energy systems will require solar generation, storage, and energy management to operate as one coordinated infrastructure. This is exactly the direction we are taking with LONGi ONE in Europe,” said Jia Chao.

Predictive safety and operational stability move into focus

A major focus of the event was the role of safety within large-scale storage systems. LONGi introduced its iCCS (intelligent Cell Connection System) as a predictive safety and early-warning architecture capable of detecting abnormalities directly on cell level long before critical thermal conditions develop.
During the presentation, LONGi explained how iCCS continuously monitors voltage, temperature, pressure, leakage behavior, and electrical anomalies directly on cell level. The system can identify changes in internal cell resistance months before potential thermal risks develop, while additional warning stages detect gas formation and abnormal cell behavior several minutes before critical thermal conditions occur.
LONGi additionally referenced more than 13 GWh of deployed storage capacity without recorded thermal runaway incidents.

Discussions throughout the event also emphasized that future storage systems will increasingly be evaluated not only by battery capacity, but by long-term operational reliability, predictive monitoring capabilities, and coordinated system communication between core components.

Storage portfolio for commercial, industrial, and hybrid applications

LONGi presented several solutions within the LONGi ONE portfolio designed for different commercial, industrial, and hybrid application scenarios.

The OmniCube L233 was introduced as a modular and scalable storage solution for commercial and industrial applications requiring high energy density, flexible expansion capability, and stable operation under dynamic load conditions.

LONGi also provided an outlook on the upcoming Hi-MO One Pro platform, expected to become available by the end of the year. The system is designed for hybrid energy applications, long-duration backup, and microgrid environments integrating photovoltaics, storage, grid connection, and additional power sources within one coordinated architecture.
In addition, LONGi presented the D5 and D9 combiner cabinets designed for different hybrid energy applications. The D5 supports standard grid-connected operation, while the D9 is intended for microgrid and off-grid environments integrating photovoltaics, storage systems, diesel generators, and load-side energy coordination.

First German C&I storage installation enters operation in Stralsund

The event also highlighted LONGi’s first commercial and industrial battery storage installation in Germany, recently completed in cooperation with the municipal utility company Stadtwerke Stralsund and LONGi’s installing partner Solarpraxis. The project integrates an OmniCube storage system into an existing solar thermal power plant and primarily serves as a backup power solution for critical infrastructure within the facility.

The installation was presented as an example of how storage systems are increasingly becoming part of essential energy infrastructure in Germany. In addition to supporting operational continuity during grid disturbances or power outages, the project demonstrates how storage can be integrated into existing energy environments to improve resilience and long-term system stability.

The case was presented during the event by Felix Eichhorn, CEO of Solarpraxis Engineering GmbH, who provided insights into the project integration and the growing role of storage systems within municipal energy infrastructure.

Growing storage demand creates opportunities across the German C&I market

The successful launch event reflected the growing momentum of the European storage market and LONGi’s transition into an integrated solar and storage provider for commercial, industrial, and hybrid energy applications in Europe.
Discussions throughout the event made clear that storage is rapidly becoming a central operational layer of Europe’s future energy systems, particularly within the commercial and industrial sector.
