Sungrow Unveils Innovative DC-Coupled PV-ESS Solution for Europe’s Energy Transition

Sungrow Leads the Charge in Energy Transition

As the energy transition continues to gain momentum, Sungrow, a global leader in renewable power technologies, has made significant strides in advancing solar energy systems in Europe. During the recent Sungrow PV-ESS Summit, the company introduced an innovative DC-coupled solution aimed at redefining the value of large-scale photovoltaic energy storage systems (PV-ESS).

Understanding the Need for DC-Coupled Solutions

With Europe poised to exceed 15 GWh in cumulative PV and storage capacity by 2029, challenges such as high costs and efficiency limitations have hindered progress. The adoption of DC coupling in photovoltaic systems can mitigate these issues, enhancing operational efficiency and energy management flexibility. Sungrow’s latest solution effectively addresses these challenges while promoting greener energy.

Key Features of the New PV-ESS Solution

The centerpiece of Sungrow's new offering is a unified design framework that integrates several innovative technologies:

- 1+X Modular Inverter: This highly adaptable inverter is tailored for dedicated storage interface, optimizing performance.
- PowerTitan 3.0: A cutting-edge component that incorporates a DC/DC module for efficient energy conversion and management.
- PV-ESS Synergy Management System: This intelligent system enhances energy management across European solar projects, facilitating seamless coordination between PV generation and storage.

Empowering Large-Scale Solar Projects

This integrated platform design allows for up to 8 hours of discharge and achieves a remarkable DC/AC ratio of 2.0. It maximizes the efficiency of energy use during peak and off-peak hours, thereby ensuring a reliable green energy supply around the clock. By enhancing system costs, energy conversion, and power regulation, this solution sets the foundation for superior project value.

Lifecycle Cost Efficiency

One of the most striking benefits of this DC architecture is the substantial cost savings it provides. By eliminating the need for dedicated power conversion systems (PCS) and medium voltage stations, as well as significantly reducing AC wiring needs, projects can save over €1 million in capital expenditures (CAPEX) for a typical install of 100 MW PV alongside 200 MWh of storage. Additionally, the solution enhances overall energy conversion efficiency by 3-5%, which contributes to long-term profitability.

Simplified Installation and Enhanced Performance

Sungrow’s integrated architecture simplifies the installation process, allowing for faster grid connection and commissioning. The solution includes adaptive control software that ensures optimal performance throughout the project lifecycle. Sungrow’s extensive service network across Europe further guarantees reliable operation and effective management of these systems, maximizing ROI for large-scale PV and storage ventures.

Intelligent Dispatch and Energy Supply Optimization

The intelligent system automatically stores excess photovoltaic production during peak times, recharging quickly when production is high and prices are low. This smart regulation minimizes losses, stabilizes PV production, and ensures a continuous, reliable energy supply.

Advanced Grid-Forming Technology

Designed to operate within increasingly complex European grids, Sungrow's solution incorporates advanced grid-forming capabilities that ensure system stability under varying conditions. These features allow for improved inertial support and rapid frequency response, minimizing downtime and boosting overall reliability.

Proven Reliability in Diverse Markets

Currently deployed in over 90 projects globally, including a notable installation of 100 MW PV plus 220 MWh in Australia and a 181 MW PV with 638 MWh in Chile, Sungrow's single-platform PV-ESS system has demonstrated its efficacy across various grid environments.

Commitment to Future Innovation

With the introduction of the PowerTitan 3.0 and the DC-coupled solution in Europe, Sungrow is steadfast in its commitment to technological innovation that accelerates Europe’s energy transition. With over 29 years of expertise in sustainable technology development, the company is poised to redefine the important role solar and storage systems play in global energy solutions.
