MUNICH, June 25, 2026 /PRNewswire/ -- As solar PV rapidly emerges as a major power source in the global energy mix, power systems are facing increasing pressure to balance supply and demand while ensuring stability under highly dynamic operating conditions. Conventional PV-storage systems, however, were not designed to effectively manage this level of variability and complexity.

To address this challenge, Sungrow introduces PowerMatrix™ at Intersolar Europe 2026 — a next-generation energy system built on five core innovations, including multi-port topology, native PV-storage integration, distributed control, reconfigurable energy paths, and source-level grid-forming. PowerMatrix delivers source-level stability while maximizing the efficiency and economic performance of utility-scale PV projects.

System-Level Optimization for Lower LCOE

PowerMatrix moves beyond single-equipment optimization, enabling coordinated system-level optimization across the entire PV-storage architecture. Through integrated equipment design, simplified engineering, and flexible capacity configuration, it reduces BOS costs by over 10% while improving efficiency across the energy value chain from generation to consumption. Combined, these cost and efficiency gains significantly reduce LCOE.

In a reference system designed for 1 GW of rated grid connection capacity, 8 GWh of installed ESS capacity, and 3,000 annual full-load operating hours in China, the PowerMatrix reduces total CAPEX by approximately $120 million compared to a conventional AC-coupled architecture, with savings across substation & transmission cable, ESS equipment, PV equipment, and other system components.

End-to-End Efficiency Boost: +5% System Energy Yield

Traditional PV-storage systems typically optimize individual components or localized segments, leading to efficiency losses across multiple stages of the energy flow and limiting overall system performance. PowerMatrix addresses this challenge through end-to-end optimization across the full energy value chain, from generation to consumption.

• PV Side: A high-density MPPT architecture with up to 28 MPPTs per MW enables finer string-level optimization, reducing mismatch losses from shading, orientation differences, and module aging, and improving PV generation.
• Storage Side: Cell-to-plant SOC balancing increases usable storage capacity across the full lifecycle, improving total discharge energy by approximately 8%.
• Conversion and Transmission: Direct PV-to-storage charging reduces two conversion stages, improving energy transfer efficiency by 3%–5% while dynamic energy routing further reduces conversion losses.
• Renewable Energy Absorption: PowerMatrix enhances the system's ability to absorb higher PV generation, increasing renewable utilization and reducing solar curtailment.

From Compensated Stability to Inherent Stability

Unlike conventional PV-storage systems that rely on external balancing resources for stable operation, PowerMatrix embeds stability at the generation-unit level, enabling a stable power supply and enhanced grid-support capabilities.

• 24/7 renewable energy supply. PowerMatrix integrates PV, storage, multiple load types, and multiple grid connection points within a unified architecture, featuring native PV-storage integration and supporting up to 260% PV DC/AC ratio and 200% ESS capacity. Annual full-load hours reach up to 3,000, approaching the operational profile of traditional generation assets.
• Local faults are automatically isolated to ensure uninterrupted operation, enabled by redundant energy supply paths and dynamic switching of optimal power flow routes based on real-time operating conditions.
• On-demand power supply is enabled, supported by unified PV-storage dispatch and distributed control, allowing each energy zone to dynamically adapt based on demand and system conditions.
• 10 ms voltage stabilization and 5 ms inertia response are achieved by PowerMatrix's grid-forming architecture. Each generation unit functions as a grid-forming node, with each sub-array independently capable of grid-forming operation.

Leveraging these system-level advantages, PowerMatrix delivers optimized performance and adaptability across utility-scale, commercial and industrial (C&I), microgrids, and AI data center applications. It enables key capabilities for next-generation power systems, including multi-source integration, bidirectional power flow, flexible dispatch, and high system reliability.

Forschende der Universität Zürich (UZH) haben einen Ansatz entwickelt, mit dem sich akuter Schlafmangel im Speichel nachweisen lässt. In einer aktuellen Studie identifizierte das Team um Thomas Krämer vom Institut für Rechtsmedizin eine Art metabolischen Fingerabdruck, der starke Übermüdung zuverlässig anzeigt. Die Resultate wurden im Fachmagazin „Journal of Proteome Research“ veröffentlicht und von Krämer als „Meilenstein für die forensische Forschung“ bezeichnet.

Für die Untersuchung rekrutierten die Wissenschaftler 20 gesunde junge Männer, die normalerweise sieben bis neun Stunden pro Nacht schlafen. Die Probanden durchliefen drei Szenarien: eine Nacht komplett ohne Schlaf, vier Nächte mit jeweils zwei Stunden weniger Schlaf als üblich sowie eine Kontrollbedingung mit rund acht Stunden Schlaf. Nach jeder Phase wurden Speichelproben entnommen und mittels hochauflösender Massenspektrometrie analysiert. Mithilfe von maschinellem Lernen suchte das Team nach molekularen Mustern, die spezifisch auf akuten Schlafentzug hinweisen.

Die Auswertung ergab, dass starke Übermüdung rund zehn Prozent aller Biomoleküle im Speichel beeinflusst. Aus zehntausenden gemessenen Molekülen filterten die Forschenden schließlich zehn spezifische Biomarker heraus, die als Signatur für akuten Schlafmangel dienen könnten. Diese erstmals im Speichel identifizierten direkten Marker für Übermüdung unter alltagsnahen Bedingungen gelten aus Sicht der UZH als Grundlage für neue diagnostische Verfahren.

Langfristig zielt das Projekt auf die Entwicklung eines Schnelltests, der vor Ort eingesetzt werden könnte – etwa im Strassenverkehr, in sicherheitskritischen Berufen oder bei der forensischen Abklärung von Unfällen. Die Forschenden betonen jedoch, dass es sich derzeit um eine Grundlagenstudie mit einer kleinen und homogenen Probandengruppe handelt. Bevor ein solcher Speicheltest in der Praxis Anwendung findet, seien umfangreichere Untersuchungen mit grösseren und vielfältigeren Bevölkerungsgruppen erforderlich.
