Sungrow Unveils PowerTitan 3.0 and DC-Coupled PV-ESS Platform in Europe

Sungrow has unveiled its next-generation PowerTitan 3.0 energy storage system (ESS) and a new Single-Platform Design for DC-coupled PV-ESS solutions at the Sungrow PV & ESS Summit held in Spain. 

PowerTitan 3.0 Targets Utility-Scale Storage Needs

The newly launched PowerTitan 3.0 is designed as a next-generation utility-scale energy storage system. It features 600Ah-plus stacked battery cells combined with silicon carbide (SiC) power conversion systems (PCS), supporting discharge durations ranging from 2 to 8 hours.

Each 20-foot container integrates a 1.78 MW PCS and 7.14 MWh of battery capacity. In a four-hour configuration, a single block can reach 7.2 MW/28.5 MWh, positioning the system for large-scale deployments across Europe. The SiC PCS offers a power capacity of 450 kVA per unit and achieves a maximum efficiency of 99.3 percent, while the stacked battery cells contribute to a system-level round-trip efficiency of 92 percent.

The PowerTitan 3.0 is factory pre-installed and pre-commissioned through an AC block design. According to the company, the system supports self-configuration and self-checks within one hour, enabling a 1 GWh project to be deployed in approximately 12 days.

Designed for Europe’s diverse climatic conditions, the system can operate without derating at temperatures as low as minus 40 degrees Celsius, making it suitable for Nordic, Alpine, coastal, and high-humidity environments.

DC-Coupled PV-ESS Single-Platform Architecture Introduced

Alongside PowerTitan 3.0, Sungrow introduced a Single-Platform Design for DC-coupled PV-ESS solutions. The platform combines the company’s 1+X modular inverter series with a dedicated energy storage interface, PowerTitan 3.0 equipped with a built-in DC/DC module, and a self-developed PV-ESS Synergy Management System.

The integrated design enables discharge durations of up to eight hours, supports a DC/AC ratio of up to 2.0, and allows an ESS power ratio of up to 100 percent. Sungrow stated that the architecture delivers system-level cost optimisation and improves energy conversion efficiency by approximately 3–5 percent.

The solution is designed to address European market requirements, including energy arbitrage using peak and valley tariffs, continuous green power supply, improved grid compatibility, and reduced renewable integration pressures. Sungrow said its DC-coupled PV-ESS solution has been deployed in more than 90 projects worldwide to date.

Focus on Grid-Forming Capabilities for Renewables-Rich Grids

Grid-forming technology was another key focus at the summit, as Europe increases renewable energy penetration. Henry Liu, Director of Sungrow’s Grid Solution Department, outlined the role of grid-forming systems in supporting stable and resilient power networks while aligning with evolving European Union standards.

Sungrow presented capabilities including voltage and frequency support, oscillation damping, system strength support, and gigawatt-scale black start functionality. The company stated that these features have been demonstrated in multiple projects, including a 7.8 GWh energy storage installation in Saudi Arabia, described as the world’s largest grid-forming storage project.

“In 2026, Sungrow continues to prioritise Europe as a pivotal market, reinforcing its commitment through a robust localised service infrastructure,” said James Li, Vice President of Sungrow Europe. 

“Today, Sungrow's European operations are built on a widespread and specialised service network supported by more than 280 engineers, 5 repair workshops, 14 service warehouses, and over 220 service partners. Our two major service centres in Pamplona (9,000 m²) and Munich (5,000 m² including outdoor facilities) serve as hubs for technical training, service innovation, and regional support. Looking ahead, Sungrow will be continuously advancing our European presence through strategic partnerships and next-generation technologies focused on supporting the continent's green energy transition,” he added.
