Sungrow Unveils PowerMatrix to Enhance Efficiency and Grid Stability for Utility-Scale Solar Projects

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. 

Challenging this, 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 maximising the efficiency and economic performance of utility-scale PV projects.

PowerMatrix moves beyond single-equipment optimisation, enabling coordinated system-level optimisation across the entire PV-storage architecture. Through integrated equipment design, simplified engineering and flexible capacity configuration, it reduces BOS costs by over 10 percent 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 USD 120 million compared to a conventional AC-coupled architecture, with savings across substation and transmission cable, ESS equipment, PV equipment and other system components.

Traditional PV-storage systems typically optimise individual components or localised 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 optimisation across the full energy value chain, from generation to consumption.

PowerMatrix improves the efficiency of solar-plus-storage systems across multiple stages of energy generation, storage and transmission. On the photovoltaic (PV) side, its high-density Maximum Power Point Tracking (MPPT) architecture, featuring up to 28 MPPTs per megawatt, enables finer string-level optimisation. This helps reduce mismatch losses caused by shading, varying panel orientations and module ageing, thereby enhancing overall solar power generation. On the energy storage side, the system uses cell-to-plant State of Charge (SOC) balancing to maximise usable storage capacity throughout the battery's lifecycle, resulting in an estimated 8 percent increase in total discharge energy. In terms of energy conversion and transmission, direct PV-to-storage charging eliminates two conversion stages, improving energy transfer efficiency by 3–5 percent, while dynamic energy routing further minimises conversion losses. Additionally, PowerMatrix enhances the system's ability to absorb higher levels of solar generation, increasing renewable energy utilisation and reducing the curtailment of solar power.

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.

PowerMatrix is designed to deliver a reliable 24/7 renewable energy supply by integrating photovoltaic (PV) generation, energy storage systems, multiple load types and multiple grid connection points within a unified architecture. The platform features native PV-storage integration and supports up to a 260 percent PV DC/AC ratio and 200 percent Energy Storage System (ESS) capacity, enabling annual full-load operating hours of up to 3,000—comparable to those of conventional power generation assets. To ensure uninterrupted operations, the system automatically isolates local faults through redundant energy supply paths and dynamically switches to the most efficient power flow routes based on real-time operating conditions. It also enables on-demand power delivery through unified PV-storage dispatch and distributed control, allowing each energy zone to adapt dynamically to changing demand and grid conditions. Additionally, PowerMatrix's grid-forming architecture provides rapid grid support, achieving voltage stabilisation within 10 milliseconds and inertia response within 5 milliseconds. Each generation unit functions as an independent grid-forming node, while every sub-array is capable of operating autonomously to enhance overall grid stability and resilience.

Leveraging these system-level advantages, PowerMatrix delivers optimised 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.
