The SNEC 2026 solar PV and energy storage exhibition in Shanghai, China, became the focal point for product unveilings and demonstrations by major industry participants. Held from 3-5 June at Shanghai’s National Exhibition and Convention Center, the event drew estimated crowds in the hundreds of thousands, solidifying its status as China’s premier trade fair and the largest globally.
In prior years, certain enterprises deliberately opted to debut flagship offerings at international gatherings like RE+ in the United States, Intersolar/ees Europe, and the publisher’s own Energy Storage Summit series. Although this pattern is anticipated to persist given market developments, SNEC continues to serve as a crucial venue for technology vendors seeking visibility.
Given its roots and primary emphasis on solar PV, it comes as no surprise that, in addition to dedicated energy storage and battery firms, the dominant players in China’s solar sector leverage this occasion to highlight their escalating focus on battery energy storage system technologies.
The foremost lithium-ion OEM globally provided initial insights into the technical details of its upcoming sodium-ion BESS product line. CATL’s sodium-ion BESS container is slated for its debut mass shipments in the third quarter of 2026. Adopting the conventional 20-foot container footprint typical of Li-ion BESS units, this product delivers 3.07MWh of energy storage and weighs roughly 47 tonnes. CATL asserted a cycle life of 15,000 cycles at 25 degrees Celsius, decreasing to 9,000 cycles at 45 degrees Celsius, claiming this represents an 80% performance improvement over Li-ion under elevated temperatures. Its 316Ah Na-ion cell, also presented at SNEC 2026, integrates seamlessly with the company’s current 587Ah lithium iron phosphate system framework, encompassing container and module design, battery management system communication, and power conversion system compatibility.
BESS-focused Li-ion manufacturer Hithium introduced its 8-hour native long-duration energy storage system, the Power 6.9MWh BESS, at the expo, alongside the debut of its Cell 650Ah large-capacity storage battery and a 10+MWh variant of Power. The firm stated that these products, engineered specifically for LDES uses and initially launched in late 2025, address market needs for economical, secure, dependable, and mass-producible options. Hithium identified LDES as a key strategic focus. Within the standard 20-foot ISO container format, the Power system incorporates a 1300Ah cell developed by Hithium. Engineered for a 25-year operational lifespan, this solution can be arranged in side-by-side or back-to-back layouts. Beyond displaying its complete product lineup, including 1175Ah and 587Ah cells, 2-4-hour Li-ion BESS versions, and a 1MWh Na-ion BESS, Hithium also finalized a 1GWh, three-year strategic collaboration agreement at SNEC 2026 with DSS Solar, a Vietnamese provider of residential, commercial, and industrial energy solutions.
After its comparatively recent move into the energy storage sector and the acquisition of system integrator PotisEdge, solar PV heavyweight LONGi attended SNEC 2026 to promote its solar-plus-storage initiative, LONGi ONE. The concept aims to deliver an integrated offering to clients, minimizing dependence on sourcing from various vendors and thereby reducing complexity and potential efficiency losses in system design and project implementation. The LONGi ONE lineup encompasses utility-scale, C&I, and microgrid BESS solutions along with PCS technology. The company claimed its OneBank 2.0 and OneMatrix 2.0 utility BESS products attain 93% round-trip efficiency, while cluster-level management boosts lifetime energy throughput. These systems can also achieve 99% availability, according to a LONGi statement. Furthermore, its C&I solution, Hi-MO One, boosted onsite solar utilization by 30% in a recent Chinese project, LONGi stated. The comprehensive integration also offers clients a single point of accountability, a frequent challenge for developers.
Vertically integrated battery producer and BESS technology firm EVE Energy, mirroring others, displayed a high-energy-density 20-foot BESS unit. Alongside its current Mr Big series of BESS enclosures, this new product promises over 6.9MWh of energy capacity within the same footprint. EVE indicated that cell-to-pack integration allows its Li-ion BESS to exceed 10,000 cycles, supported by multiple fire safety layers. Additionally, during the event, the company announced it had inked agreements totaling more than 67GWh. These deals were made with Chinese entities Shanghai Power Electronics, Jiangsu Vertrans Energy Technology, Zhejiang Savant Digital Technology, Tianjin RY Energy, and Brazilian firm Genesis Energia e Technologia.
Battery and BESS manufacturer Rept Battero, besides featuring soccer star Ivan Cordoba at the expo to commemorate its partnership with Italian club Inter Milan, unveiled its new Na-ion cell. Rept Battero’s 320Ah sodium-ion variant of its Wending battery cell targets large-scale BESS applications. The company asserted that the Wending 320Ah can achieve 20,000 cycles and sustain energy efficiency of 97% or more during charge-discharge cycles. The firm also presented a new 85Ah high-power lithium-ion cell, tailored for backup power and peak shaving needs of artificial intelligence data centers. This cell supports a 10C maximum continuous discharge rate with a cycle life exceeding 60,000 cycles and has passed thermal runaway, needle penetration, and other safety assessments.
Primarily recognized for its module-level solar inverters, Hoymiles, akin to LONGi, exhibited products for the solar-plus-storage market at SNEC 2026. Hoymiles launched the HoyPrime AC 6.126MWh AC container, along with its other utility-scale, C&I, residential, and DIY energy storage offerings. HoyPrime consolidates batteries, PCS-level controls, and system-level energy management into a single platform. The company stated that its factory pre-assembly and pre-commissioning streamline on-site installation and cut commissioning times while maintaining product quality uniformity. For the C&I sector, Hoymiles showcased its C&I all-in-one BESS solutions, including a DC-coupled model. Additional products featured a grid-forming PCS for solar in weak-grid settings, balcony solar kits, and a residential all-in-one battery system.
GCL System Integration Technology introduced a mobile solar PV storage solution, the EcoPower Mate, for its initial public display. Targeting off-grid markets such as mining and heavy industry in remote areas, GCL SI claimed it can supply on-site power at a notably lower cost than comparable diesel generation and backup capacity.
Electric vehicle charging and BESS solutions provider StarCharge presented its new solid-state transformer. This SST enables medium-voltage direct connection and six-way power output, which StarCharge stated enhances conversion efficiency for heavy-duty EV charging stations, utility-scale BESS, and data centers. StarCharge’s product range also included liquid-cooled EV charging solutions, a 960kW integrated solar-plus-storage charging system, and its own 6.25MWh BESS container utilizing 587Ah battery packs. The company also revealed a renewable energy, virtual power plant, and investment partnership with Australian renewable energy product distributor SolarJuice during the expo.
