Envision's Innovations for Clean Energy

At the Intersolar Europe 2026 event held in Munich, Envision revealed its state-of-the-art integrated energy systems, designed to deliver controllable clean energy for artificial intelligence (AI), industrial applications, and electricity grids. The company showcased a comprehensive portfolio that includes the AI Power System tailored for AI data centers, the Gen 8 4.X MWh long-duration energy storage system, and a full-stack hybrid solution combining wind, solar energy, and storage, all featuring Envision’s proprietary photovoltaic inverter.

Comprehensive Approach to Energy Solutions

Envision's presentation highlighted a systematic approach that connects, stores, and manages energy resources across various architectures. These solutions specifically target three critical scenarios: powering AI infrastructures, stabilizing grids with high renewable energy penetration, and accelerating industrial decarbonization.

Kevin Huang, Senior Vice President of Energy Storage, emphasized the growing demand for reliable, affordable, and low-carbon electricity as a bottleneck to the expansion of both the AI sector and industrial operations. He pointed out that the next phase of the energy transition will not only be driven by cost per watt-hour but by the competitiveness of the entire electricity grid.

The AI Power System: Addressing Future Challenges

The AI Power System addresses a pivotal challenge in the evolving needs of AI infrastructures, where computational requirements are rapidly escalating, outpacing the availability of clean and reliable energy. This new system coordinates power generation, grid interaction, storage, and computational loads across three integration layers: grid-side hybrid systems of wind, solar, and storage, mid-voltage network-forming battery energy storage systems (BESS), and an 800-volt direct current architecture that integrates solid-state transformer (SST) technology with energy storage.

The Envision 2.5-MW SST container converts 10/13.8 kV alternating current into 800-volt direct current with an impressive efficiency of up to 98.5%, significantly reducing copper use by up to 80%. To meet the dynamic energy demands of AI data centers, Envision offers two complementary 800-volt direct current energy storage solutions. The compact lithium iron phosphate-based system provides up to 2.5 MW capacity over two hours and beyond for backup and energy shifting. Simultaneously, the sodium-ion solution rapidly charges and discharges within minutes, offering high thermal stability, excellent performance, and an extended cycling lifespan.

These technologies collectively enhance the efficiency and reliability of AI data center operations while supporting the increasingly dynamic load profiles of advanced GPU clusters. Envision's AI Power System has already showcased its potential to improve energy efficiency in computing processes and increase the reliable use of renewable energy, thereby streamlining grid startup times while unlocking additional capacity from existing grid resources as project conditions permit.

Currently operational at the Chifeng Net-Zero Industrial Park, Envision’s AI Power System plays a key role in a pioneering initiative developed alongside Tencent, a leading provider of cloud and AI services. Furthermore, in Ulanqab, Envision is constructing the “Envision Galaxy Campus,” a gigawatt-scale AI data center powered by directly connected renewable energy, demonstrating how AI infrastructure can be designed from the outset to utilize clean, controllable energy. This initiative forms part of “Mission Gobi,” Envision's global effort aimed at establishing 5 GW of green AI data center capacity in desert and arid regions by 2030.

Gen 8 LDES: Long Duration Energy Storage for Renewable Grids

In addition to the AI Power System, Envision launched the Gen 8 4.X MWh long-duration energy storage system crafted specifically for grids heavily reliant on renewable sources. This system, employing self-developed cells and SiC-string PCS technology, offers a 250% overload capability for grid-forming applications. Its design maintains true voltage source behavior during extensive transient events typically evaluated in grid impact studies, which helps developers remain competitive in commercial grid-forming services.

Capable of storing energy for 8 to 16 hours, it boasts a round-trip efficiency of up to 91% with a projected operational lifespan of 25 years. In favorable scenarios, it is engineered to enhance the project’s internal rate of return through greater system efficiency, space-saving design, and long-term operational value improvement by 1 to 3 percentage points.

The Gen 8 system is designed with enhanced state-of-charge accuracy of 2% and operates at a noise level 15 dB(A) below industry standards. Built to withstand harsh environments, it reliably functions in temperatures ranging from -40 °C to 50 °C and optionally features C5H class corrosion protection. Its modular design reduces space requirements by more than 30% compared to typical 5–7 MWh systems while maintaining transport and installation simplicity with individual units weighing under 30 tonnes.

Full-Stack Hybrid Solution: Seamless Coordination of Renewables

Envision's hybrid solution for wind, solar, and storage provides controllable clean electricity around the clock for industrial and utility customers throughout the project lifecycle—from planning to delivery and long-term operations. At Intersolar Europe 2026, Envision expanded this solution by introducing its grid-connected PV string inverter to the European market. This advancement combines its proprietary power electronics with a real-time coordination platform, enabling an integrated solar-storage operation within a single system architecture.

The solution facilitates millisecond-level coordination from the module to system scale, improving system performance, reliability, and project cost-effectiveness. For industrial clients, Envision’s
