Next-generation utility PV platform redefines lifecycle optimal LCOE to support Europe's energy transition
[FRANKFURT, Germany, April 29, 2026] Huawei Digital Power today officially launched the FusionSolar9.0 Smart PV Solution in Europe at a dedicated summit in Frankfurt, Germany, under the theme "Pioneering Ultimate Innovation, Redefining Life Cycle Optimal LCOE." The launch marks a defining milestone for Huawei's smart PV roadmap in the world's rapidly evolving energy markets, bringing together leading utilities, project developers, technical experts, and industry associations from across the continent.
The European Industry Challenge: Grid Stability, Safety, and the LCOE Imperative
Europe's energy transition, while a landmark achievement for decarbonization, has introduced severe structural challenges across both the technical and commercial dimensions of the power system.
As traditional synchronous generators — thermal and hydropower — are progressively decommissioned, the grid's inherent system inertia and short-circuit strength have declined sharply. The result is a network increasingly exposed to frequency and voltage fluctuations, raising the risk of large-scale instability. Grid-forming capability, once the exclusive domain of conventional generation, has become one of the most critical requirements for next-generation renewable assets.
In the meantime, growing complexity in ensuring safety and reliability. As equipment power ratings increase and plant application scenarios diversify, ensuring the safe and reliable operation of PV plants has become more challenging.
On the commercial side, for investors and plant owners, achieving lower LCOE throughout the entire project life cycle remains a top priority.
Against this backdrop, the European PV industry faces interconnected challenges that no conventional solution has been able to address holistically: full-lifecycle LCOE pressure, grid stability at high renewable penetration, and growing complexity in safety and reliability management.
Opening Address: Redefining Life Cycle Optimal LCOE
The summit was opened by Jacky Chen, President of Huawei Digital Power Europe, who set the strategic context for the launch and outlined Huawei's long-term commitment to the European energy transition.
"The question is no longer how much renewable capacity we can install, but how we ensure that capacity is smart, grid-stable, and economically resilient over its full lifecycle. Delivering high-quality solutions and enabling sustainable revenue growth for our customers are our top imperatives. FusionSolar9.0 is our answer to that challenge for the European market."
Jacky Chen emphasized that Huawei's strategy in Europe is centered on delivering measurable lifecycle value — enabling developers, utilities, and asset owners to achieve stronger returns, more reliable operations, and active grid participation in an increasingly complex regulatory and market environment.
FusionSolar9.0: Breakthrough Innovations for a New Era
Steve Zhang, President of Utility, Commercial & Industrial Solar Business at Huawei Digital Power, presented FusionSolar9.0 as the most significant step-change in smart PV architecture since the transition to string inverters — a system engineered from the ground up to address the specific demands of today's high-penetration, grid-constrained energy landscape.
FusionSolar9.0 is built on industry-first technological innovations:
• The industry's first 1000V AC PV system. Following the transition from 500V to 800V AC, Huawei has achieved the next breakthrough with 1000V AC technology, enabling larger array configurations, reduced balance-of-system costs, and a stronger foundation for the next decade of utility-scale development.
• The world's first grid-forming string inverter. Extending grid-forming capability — previously limited to energy storage systems — directly into PV and PV+ESS solutions. This is a fundamental shift in how solar assets can interact with and actively support the grid.
• Europe's largest 11MW Smart Transformer Station. Enabled by higher power ratings and voltage levels, this dramatically reduces system complexity at utility scale.
These innovations are delivered through the new 506KTL Smart String Inverter and the new generation 3000/7000/11000kVA Smart Transformer Stations, together forming a complete, integrated utility-scale platform.
Core Values: Measurable Gains Across the Full Lifecycle
FusionSolar9.0 translates its technical breakthroughs into four areas of concrete, quantifiable value for European project developers and asset owners:
1. Optimised Investment Returns
• BOS cost reduction of 0.27-0.55 Euro Cents/Wp through the 11MW array configuration enabled by the 506KTL inverter
• Commissioning cost savings of approximately 70,000 Euros per -200MW project, by leveraging PV-generated power via grid-forming capability to replace conventional diesel gensets during commissioning
• Longer PV string design and expanded MPPT voltage range increase effective generation hours, with earlier morning start and later evening shutdown — particularly valuable in markets with time-of-use pricing
2. Active Grid Support
The world's first Smart String Grid-Forming Inverter directly addresses Europe's most pressing grid stability challenge. Four key capabilities define its performance:
• Reactive power generation within 10ms in response to voltage instability — three times faster than conventional grid-following inverters
• Enhanced short-circuit ratio (SCR), increasing renewable transmission capacity
• Smart Virtual Inertia (0–20s) to support frequency stability as synchronous generation is phased out
• Automatic reactive power recovery at nighttime after fault clearance, preventing grid-code penalty exposure
3. Enhanced Safety and Reliability
• Industry-first Smart Hybrid Cooling System improves heat dissipation capacity by 30%, reducing thermal stress and extending product lifespan
• Upgraded Smart Three-level DC Safety Protection (SSLD v2.0): active fault identification, millisecond-level disconnection, and Smart Auto-locking to prevent fault propagation from manual error
• New-generation IGBT module increases voltage withstand capacity by 25%, reduces power loss by 10%, and raises maximum junction temperature by 20%
• Fully automated and intelligent manufacturing line for the 506KTL inverter, ensuring consistent quality at scale
Industry Perspectives: Expert Voices from the Summit
The launch summit brought together leading voices from across the European and global energy sector, reflecting the breadth of stakeholder confidence in FusionSolar9.0's technical and commercial proposition.
"The bankability and innovation assessment of the SUN2000-506KTL confirms that Huawei's latest generation inverter sets a new reference point for utility-scale solar in Europe. Grid-forming capability, combined with this level of system integration, is what the market has been waiting for."
"Scaling power without evolving safety design will scale risk, not progress. Reliable deployment at scale requires parallel investment in safety innovation — and that is precisely what we are seeing in FusionSolar9.0."
"The shift from waste to a self-optimizing energy system is not theoretical — it is achievable today through closed-loop microgrid design with FusionSolar9.0 solution. The capabilities introduced in this generation of smart PV fundamentally change what is possible for European utility developers."
"The BOS comparative analysis of the Huawei SUN2000-506KTL inverter demonstrates clear and quantifiable advantages in system cost reduction. For project developers evaluating technology choices, the numbers speak for themselves."
"Grid-forming standardization is no longer a future ambition — it is the pathway to ensuring future power system stability and resilience. The industry needs technology that can meet this standardization today."
Market Deployment and Ecosystem Readiness
FusionSolar9.0 is not a concept — it is already in large-scale deployment. Since October 2024, Huawei has rolled out the solution across diverse scenarios in the Chinese market, and international adoption is accelerating rapidly. More than 10GW of projects globally are currently under construction using FusionSolar9.0, as developers across multiple markets have re-evaluated their designs in favour of the solution's lower BOS and superior lifecycle economics.
A common concern at this stage of a platform upgrade — ecosystem readiness — has been proactively addressed. The full 1000V AC supply chain, spanning PV modules, switches, transformers, and other key components, is mature and ready for large-scale European deployment. Huawei engaged with ecosystem partners throughout the development process to ensure seamless integration from day one.
Looking Ahead
With the European launch of FusionSolar9.0, Huawei reaffirms its commitment to supporting the continent's energy transition with solutions that are technically leading, commercially robust, and built for the long term. By enabling solar plants to become intelligent, grid-supporting assets — not passive generation sources — FusionSolar9.0 positions developers and utilities to navigate the new era of high-penetration renewables with confidence.
"FusionSolar9.0 is not just a product upgrade. It is a fundamental rethinking of what a solar plant should be capable of in 2026 and beyond. We are proud to bring this to Europe at exactly the moment the market needs it most."
