Industry Standards and White Paper for 2 000 V DC Systems in the Photovoltaic Sector Officially Released; Themed Industry Symposium Successfully Concluded

On 5 August 2025, the “2000 V PV System Standard Launch & 2000 V Technology Innovation and Application Symposium”, hosted by TÜV Rheinland, was successfully convened in Changzhou, Jiangsu. The conference focused on the technical standards and innovative applications of 2,000 V DC photovoltaic systems, drawing numerous industry leaders, experts, scholars and corporate representatives to jointly explore the development pathway for high-voltage technologies and propel a high-quality leap in the PV sector.

The event opened with addresses by Mr Lu Junfang, member of the CPC Committee and Deputy Director of the Administrative Committee of Changzhou Science and Education Town; Ms Li Han, Vice President of the PV & Storage Division at Sungrow Power; and Mr Li Weichun, Global Vice President of Power-Electronics Services at TÜV Rheinland and Vice President of Solar & Commercial Products Services for Greater China. All speakers underscored the vital role of technological innovation and standards development in sustaining the healthy growth of the PV industry and voiced strong confidence in and expectations for the large-scale deployment of 2,000 V systems.

During the conference, the much-anticipated “Technical White Paper on 2,000 V DC Systems” was officially released, marking a critical milestone for the industry in the 2,000 V PV system domain. At the launch ceremony, Ms Li Han and Mr Li Weichun jointly unveiled the white paper and delivered remarks, outlining the future direction of technological advancement. Mr Dong Bin, General Manager of Power-Electronics Services for Greater China at TÜV Rheinland, then delivered an authoritative interpretation of the white paper, offering an in-depth analysis of the standard-system framework and key technical requirements to provide systematic guidance for the industry.

The symposium served as an invaluable platform for standardisation, industrialisation and real-world deployment of 2,000 V PV systems, and sent a clear signal that the sector is steadily advancing toward higher voltages and higher efficiencies. As the standard system continues to improve and industry-wide collaboration deepens, 2,000 V systems are expected to achieve breakthroughs in an expanding range of applications, opening broader horizons for the future development of the photovoltaic industry.
