LONGi at Intersolar 2026: The next chapter of solar combines advanced BC technology with smart energy storage

At Intersolar Europe 2026, LONGi will present a portfolio spanning utility-scale energy storage, commercial and industrial storage systems, specialized back contact photovoltaic solutions for demanding environments, and high-efficiency residential solar solutions as part of the EcoLife series.

This year’s LONGi booth exhibition reflects a broader evolution in the energy market. As solar deployment continues to accelerate across Europe, project developers, asset owners, utilities, and homeowners face increasingly complex requirements related to energy management, grid integration, safety regulations, permitting, and building constraints. The technologies presented at LONGi Booth A2.170 demonstrate how photovoltaics, energy storage, safety engineering, and intelligent energy management can work together within modern energy infrastructure.

Storage solutions for C&I and utility-scale applications with predictive safety technology

A central focus of the exhibition is LONGi ONE, LONGi’s new integrated storage portfolio for commercial, industrial, and utility-scale energy applications.

The portfolio addresses increasingly complex energy environments where solar generation, energy storage, grid interaction, and intelligent energy management must operate together within a coordinated infrastructure.

Within the platform, the Hi-MO One Pro addresses C&I applications through a modular 261 kWh hybrid storage architecture that integrates EMS, BMS, PCS, thermal management, and LONGi's patented iCCS predictive safety technology. The system supports AC- and DC-coupled configurations, microgrids, off-grid operation, and backup durations ranging from 2 to 24 hours.

A key differentiator is the iCCS architecture, which continuously monitors battery behavior at cell level and is designed to identify potential thermal risks months before critical conditions develop. Typical applications include manufacturing facilities, logistics centers, charging infrastructure, industrial campuses, data centers, and hybrid PV-storage systems where energy resilience and operational continuity are essential.

For utility-scale projects, the portfolio includes the OneBank 2.0 and OneMatrix 2.0 energy storage platforms, both based on a 6.25 MWh liquid-cooled LFP architecture designed for renewable integration, grid balancing, energy shifting, and dispatchable power applications.

OneBank 2.0 is optimized for projects where operational availability, safety, and lifecycle economics are critical. The platform combines thermal runaway prediction, active fire prevention, AI-based arc fault detection, continuous insulation monitoring, and a liquid-cooled architecture with a volumetric energy density of 146 Wh/L. Rack-level management is designed to improve energy generation by up to 8%, while AI-supported temperature control contributes to longer service life. The integrated platform delivers up to 93% system efficiency and 99% uptime while supporting rapid deployment and simplified maintenance through modular system design.

OneMatrix 2.0 was developed for utility-scale projects requiring simplified system integration and accelerated deployment. The centralized architecture combines battery storage, power conversion, and medium-voltage transformation within a single pre-integrated platform. Supporting storage durations from two to eight hours, the system accommodates up to sixteen DC inputs and integrates medium-voltage transformation up to 37 kV. The design reduces installation complexity, shortens commissioning time by up to 30%, and supports more efficient deployment of large-scale storage assets.

Both systems support advanced grid services including PQ, VF, VSG, and grid-forming operation while operating in environments ranging from -30°C to +60°C.

Hi-MO X10 Guardian series expands with fire-resistant, anti-glare, and lightweight solutions

LONGi’s extended Hi-MO X10 Guardian series focuses on deployment environments where conventional module designs face technical, regulatory, safety or structural limitations.

The Hi-MO X10 Guardian Fire-Resistant module combines HPBC 2.0 back contact technology with a multi-layered fire protection architecture developed for safety-critical applications. Flame-retardant materials, reinforced junction box sealing, and high-temperature-resistant glass are designed to mitigate risks associated with hot spots and direct current arcing.

Internal laboratory testing exposed the module to temperatures approaching 1000°C for up to 1.5 hours without structural burn-through. The product has obtained TÜV Rheinland Class A fire classification as well as Fire Protection AAA certification for shading resistance, making it particularly suitable for logistics facilities, industrial buildings, public infrastructure, and commercial rooftops with stringent fire safety requirements.

The Hi-MO X10 Guardian Anti-Glare Pro addresses projects where reflected sunlight can create operational or permitting challenges. Combining HPBC 2.0 technology with micro-structured anti-glare glass, the module reduces total reflectivity to just 0.9%. TÜV Rheinland testing confirmed a Daylight Glare Probability (DGP) of 0.29 under EN 17037, corresponding to the highest AAA classification for imperceptible glare.

Despite the reduced reflectivity, the module achieves up to 24.8% efficiency and 670 W output. Under shaded conditions, hotspot temperatures are reduced by approximately 29°C and shading-related power losses by more than 70% compared with conventional module designs. Typical applications include airports, transportation infrastructure, urban developments, and projects located close to residential areas.

For structurally constrained rooftops, the Hi-MO X10 Guardian Light Design delivers up to 560 W output, 24.8% mass-production efficiency, and 250 W/m² power density while weighing only 16.3 kg, or approximately 7.2 kg/m². Compared with conventional single-glass modules, the design reduces weight by around 30%, enabling installation on many aging or load-limited commercial rooftops without structural reinforcement.

The module combines the performance advantages of HPBC 2.0 technology with lower hotspot risk and significantly improved recovery from partial shading, supporting solar deployment on industrial buildings, warehouses, logistics centers, and other rooftops previously considered unsuitable for PV installations.

LONGi launches LONGi Block, a containerized solar power station with up to 239.2 kW capacity

LONGi Block is a containerized photovoltaic solution developed for locations where reliable electricity is required without permanent energy infrastructure. Available in configurations of 119.6 kW and 239.2 kW, the system integrates LONGi's Hi-MO X10 back contact modules with up to 650 W output and 24.1% efficiency, together with mounting structures, inverter technology, and optional battery storage within a standard shipping container. The foldable design expands to a deployed area of up to 232.6 m² while maintaining a compact transport footprint. Depending on the configuration, LONGi Block can be deployed within three to four hours by a six-person team, providing a rapid source of renewable electricity for construction sites, mining operations, agricultural applications, emergency response, remote communities, temporary industrial facilities, and interim use of undeveloped land. The system combines mobile deployment with the performance advantages of HPBC 2.0 back contact technology, offering a practical alternative where conventional grid connections are unavailable or impractical.

EcoLife Series: Residential solutions focused on safety, performance, and design

The EcoLife series was developed for homeowners seeking higher energy yield, long-term reliability, and a premium rooftop appearance. Depending on the model, the portfolio delivers up to 25% module efficiency and up to 510 W output while maintaining a uniform all-black appearance without visible front-side interconnections.

At Intersolar Europe 2026, LONGi will also introduce an Anti-Glare Pro variant of the EcoLife series for the Swiss market. Based on the same anti-glare technology used in the commercial and industrial segment, the module reduces total reflectivity to just 0.9%, with TÜV Rheinland verifying a Daylight Glare Probability (DGP) of 0.29 under EN 17037, corresponding to the highest AAA classification for imperceptible glare.

The solution is designed for residential environments where reflected sunlight may affect neighboring buildings, roads, or public spaces. Its certified anti-glare characteristics help reduce visual impact and can support deployment in locations where glare is a consideration for homeowners, neighbors, or local authorities.

Zero Gap shingled technology increases active module area

As part of the EcoLife portfolio, LONGi will introduce a new shingled-cell module architecture based on a Zero Gap design. Unlike conventional modules, where visible gaps between cells reduce the active power-generating area, the shingled layout overlaps adjacent cell strips and eliminates much of the inactive space. This increases the active module surface by approximately 1.5%, contributing up to 20 W higher module output compared with conventional designs. The cell architecture also supports improved performance under partial shading, as the parallel current paths reduce the impact of localized shading on overall energy production. At the same time, the seamless cell layout creates a uniform all-black appearance, making the technology particularly attractive for residential rooftops, solar carports, and building-integrated photovoltaic applications. The Zero Gao shingled technology will be available for the Hi-MO X10 family and the EcoLife series.

Hi-MO X10 Transparent module brings solar power for carports, façades, and architectural structures

A transparent version of the Hi-MO X10 extends back contact technology into applications where daylight transmission and power generation must coexist.

The bifacial double-glass module delivers up to 495 W output and up to 24.25% efficiency while maintaining a visually uniform, gridless appearance enabled by the back contact cell architecture. With bifaciality of 70% ±5%, a 30-year power warranty, and a design suitable for carports, canopies, façades, atriums, and other architectural structures, the module combines energy generation with building integration requirements.
