WHES at Intersolar 2026: AI-Driven Innovation Unlocks a New Value Cycle for European Energy Storage

As Europe’s energy storage market shifts from policy-driven growth to value-oriented commercialization, the company presented its full-stack, self-developed portfolio of commercial & industrial (C&I) and residential energy storage solutions, together with WHES OS, its AI-native energy operating system. Designed to address key challenges in grid integration, revenue optimization, and operational safety, the showcased solutions highlighted WHES’s technological leadership in intelligent, digitalized energy storage.

Aligning with European Policy Trends: From Capacity Expansion to Grid Integration and Value Optimization

Europe’s cumulative PV capacity has entered the terawatt (TW) era, but the rapid growth of renewable generation has placed increasing pressure on electricity grids. In Germany, for example, the number of hours with negative electricity prices has reached record levels in recent years. At the same time, the gradual phase-out of fixed EEG subsidies is accelerating the transition toward market-based mechanisms, including spot electricity trading and long-term Power Purchase Agreements (PPAs). Against this backdrop, competition in the energy storage sector is shifting beyond hardware performance alone, with intelligent dispatching algorithms, energy management and market participation capabilities emerging as the key differentiators.

In response to this shift, WHES delivers end-to-end integration of hardware, software and services, empowering customers to lock in stable, predictable returns amid volatile power markets.

C&I Energy Storage: AI-Driven Dispatching and High-Safety Architecture for Revenue Optimization

As Europe’s energy storage market transitions from capacity-driven competition to value-oriented operation, purchasing priorities are evolving beyond storage capacity alone. System safety, grid compatibility and revenue optimization have become the key differentiators for energy storage solutions.

l Grid-Tied PC-G3 (125kW / 261kWh)

To fit Europe’s new landscape of revenue stacking, WHES showcased its new-generation C&I energy storage system, the PC-G3. Built on the proprietary “One Core, One Isolation” full-link active safety architecture, the product meets Europe’s stringent grid connection

and safety standards. It supports parallel expansion of up to 26 AC units (a maximum cluster capacity of 3MW) with flexible 2–8 hour energy duration configurations, perfectly suiting multi-revenue scenarios including Frequency Containment Reserve (FCR), automatic Frequency Restoration Reserve (aFRR), spot price arbitrage and demand response across Germany, the UK and other European markets.

Furthermore, the upcoming hybrid PC-G3 variant is equipped with a hybrid inverter, delivering EPS switching within 10ms and 150% overload output. While maintaining full grid market participation, it provides dual safeguards of blackout backup power and energy resilience for commercial and industrial operators.

WHES OS: AI-Native Energy Management Delivering Measured Revenue Improvements of 8–15%

To meet the growing demand for granular trading on Europe’s power spot markets, WHES launched WHES OS 2.0, the industry’s first AI-native intelligent energy operating system. Embedded with an AI Agent featuring intent recognition, the platform automatically generates and optimizes operational strategies every 15 minutes by analyzing multi-dimensional data including electricity price forecasts, on-site load and PV generation projections, and regional market rules.

The system supports natural language interaction (e.g., direct inquiries into revenue attribution), alongside strategy interpretation and decision playback functions, ensuring full transparency and traceability for every dispatching action. Deep integrations with Virtual Power Plants (VPPs) and demand management algorithms enable WHES OS 2.0 to effectively mitigate losses during negative price windows and capture high-margin revenue at peak price hours. Field test data verifies that storage sites powered by this system achieve an 8% to 15% uplift in total revenue, striking an optimal balance between profit maximization and risk control.

WHES also displayed its mature C&I product portfolio including PC-G2, PC-G1 and PC-mini. The PC-G2 features flexible 2–8 hour storage durations and a wall-mounted liquid cooling design for streamlined maintenance, ideal for fast frequency response and modular capacity expansion. The PC-G1 holds global certifications including UL9540A, UN38.3, EN50549 and IEC 62933, widely deployed for peak shaving and demand response applications. Tailored for off-grid and weak-grid environments, the PC-mini delivers seamless grid/off-grid switching and outstanding PV compatibility. The comprehensive C&I product matrix addresses diverse application requirements across

European markets.

Residential Energy Storage: Integrated PV, Storage and EV Charging for Energy Independence and Dynamic Tariff Optimization

The widespread rollout of dynamic electricity tariffs and surging electric vehicle ownership across Europe have amplified household demand for energy self-sufficiency and cost reduction. WHES presented its new-generation 8–32kWh Battery Box lineup and the ECOS smart home energy management platform.

l Battery Box (8–32kWh):WHES offers two core residential storage solutions: split-type and all-in-one units to match varied household energy needs. The Battery Box leverages high-capacity 314Ah cells, supporting mixed use of new and aged batteries, flexible capacity expansion and single-point fault isolation. With low-temperature operational performance and multi-layer safety protections, it pairs seamlessly with 3.6–6kW single-phase hybrid inverters to form highly reliable split residential storage systems. The PP-T2 all-in-one residential unit integrates batteries and inverters, supporting expandable capacity up to 160kWh, 200% PV oversizing and robust off-grid power supply to cover all household energy needs. Both product lines can be combined with EV chargers to enable intelligent coordination of solar PV, energy storage and EV charging, delivering a more efficient and user-friendly home PV-storage-charging ecosystem.

l ECOS Smart Home Energy Management Platform:The ECOS platform embeds full AI capabilities into residential energy management, compatible with all WHES residential storage systems. Users monitor real-time household energy flows via a mobile APP, with the newly launched WHES AI+ mode automatically generating operational strategies based on dynamic tariff trends, PV generation forecasts and domestic load predictions. It empowers households to shift from passive energy consumption to proactive energy management, boosting energy independence and economic returns.

Additional single-phase and three-phase all-in-one residential storage units were also on display, catering to European families’ diverse needs for backup power, smart energy management and sustainable electric mobility.

Strengthening Local Partnerships to Build Europe’s Green Energy Ecosystem

WHES’s booth drew steady crowds of industry clients and partners throughout the exhibition. As a global digital energy service provider, the company not only develops products tailored to European regulatory frameworks and market pain points, but has also established fully localized sales and operational teams across Europe, delivering one-stop services spanning product R&D, certification compliance and on-site maintenance.

Moving forward, backed by safe, reliable storage hardware and AI-powered intelligent dispatching technology, WHES will collaborate with partners worldwide to accelerate the energy transition across Europe and the globe.
