Sungrow Launches the Groundbreaking 1+X 2.0 Modular Inverter

Sungrow, a leader in inverter and energy storage systems, has recently introduced its innovative 1+X 2.0 Modular Inverter tailored for utility-scale solar power applications. Revealed at the Global Renewable Energy Summit 2025, this inverter showcases a fresh modular design, emphasizing scalability and efficiency. The 1+X 2.0 Modular Inverter is engineered for a power range from 800 kW to 9.6 MW, allowing users to flexibly scale their solar installations according to demand.

Enhanced Features and Performance

One standout feature of the 1+X 2.0 is its AI-driven fault detection that revolutionizes maintenance. By providing real-time identification of issues, it significantly reduces downtime and repair times, making it highly efficient for operators. Moreover, its modular structure allows for quick replacements of individual components, meaning operation and maintenance can be completed in just one hour per module — a vast improvement over previous inverter models.

Designed for Harsh Environments

Constructed to endure extreme conditions, such as the intense heat often experienced in regions like the Middle East, the 1+X 2.0 incorporates advanced cooling systems and high-power-density semiconductors. It operates reliably even at temperatures soaring to 52 degrees Celsius without derating, thanks to its dual-cycle thermal management system. With an IP66 rating for protection, it can withstand various environmental challenges, ensuring sustained efficiency and safety.

Prioritizing Safety with AI Technology

Safety is paramount in solar energy production, so the 1+X 2.0 addresses common vulnerabilities associated with DC circuits that can lead to faults. With its holistic AI-driven DC-side safety management system, it includes features like a dual DC arc protection system that instantly disconnects faulty circuits to prevent fires, and a terminal overheating protection system that monitors temperatures to proactively address potential risks.

This innovative approach not only mitigates the risk of electrical fires but maximizes operational reliability, which are crucial factors in large-scale deployments.

Revolutionary Grid-Forming Capabilities

Apart from energy storage installation support, the grid-forming capabilities of this inverter are also noteworthy. The inverter is equipped to maintain stability even under fluctuating grid conditions and can provide inertia support within five milliseconds, thereby quickly stabilizing the power output. Impressively, it is capable of handling transient overvoltages up to 1.8 times its rated voltage, positioning it as a leading technology in the solar sector today.

Manufacturers can leverage grid-forming technology to eliminate dependencies on diesel generators during construction periods, thus expediting project timelines and enhancing the cost-effectiveness of integrating renewable energy systems.

Economic Benefits and Market Impact

The 1+X 2.0 Modular Inverter does not only benefit operational efficiency but can also lead to significant financial savings. By complying with more PV modules per string and reducing overall system costs, a 1 GW solar plant using this technology can save approximately $7.41 million in capital and operation expenditures. This captures a critical competitive edge in the renewable energy market, enabling operators to maximize their return on investment.

Lee Zhang, Vice President at Sungrow, stated, “The 1+X 2.0 represents a paradigm shift for the utility-scale solar market. It empowers our customers to push boundaries while delivering outstanding returns on investment.”

With over 28 years of expertise in renewable energy technology and recognition as the world's leading PV inverter provider, Sungrow’s innovations continue to redefine the solar landscape globally. As we transition towards more sustainable energy solutions, products like the 1+X 2.0 will play a pivotal role in ensuring efficient, reliable, and safe energy production across diverse environments.
