HEFEI,China,April 15,2025 -- Sungrow,the global leading inverter and energy storage system provider,unveiled itsgroundbreaking 1+X 2.0 Modular Inverterfor utility-scale applicationsduringthe Global Renewable Energy Summit 2025,held April 7-9. The 1+X 2.0 Modular Inverter features a more scalable block design (800kW to 9.6MW),stable operation without derating at temperatures up to 52 degrees Celsius,AI-driven fault detection,and pioneering grid-forming capabilities,meeting the high demands for superior performance,maximum availability,and enhanced reliability of the inverter.

Sungrow 1+X Modular Inverter

Small Module,Mega Impact

The 1+X 2.0 Modular Inverter provides increased modularity compared to the previous version. With each unit having a power rating of 800kW,the inverter provides flexible scalability from 800kW to 9.6MW (single unit to 12 units in parallel). This results in great flexibility which covers various scenarios.

The product's split modular design isolates critical components (IGBTs,capacitors) in the upper inverter module for quick field replacement. Operation and Maintenance (O&M) time is slashed to one hour per module swap—the easy O&M enables field engineers to perform quick replacements.

With the AI-powered diagnostics function,the 1+X Modular Inverter provides real-time fault identification,eliminating manual troubleshooting and delays,accelerating repairs,and minimizing reliance on manpower.

Enhanced Durability in Harsh Conditions

Engineeredto be robust inharsh conditionssuch as scorching heat in the Middle East,the 1+X 2.0 Modular Inverter integrates high-power-density semiconductors,a high-efficiency heat exchangeras well asa dual-cycle thermal management system to ensure optimized heat dissipation,maintainingstableoperationwithout derating when the temperature reaches up to 52 degrees Celsius.

Its IP66protection construction provides resilience to extreme conditions.The sealed module,with internal components fully protected and using advanced heat dissipation techniques as well as self-cleaning air duct functions,will guarantee the high reliability of the inverter.

Holistic AI-Driven DC-Side Safety Management System: Eliminating Fire Risks

Addressing the industry's top challenge—mostPV system faults originate in DC circuits. The DC faults may result in short-circuit,arcing,or even fire. The 1+X 2.0 Modular Inverter is providing a holistic AI-driven DC-side safety management system to solve the issue:

Dual DC Arc Protection System

When an arc fault is detected,the combiner box reliablydisconnects the faulty circuit within40 milliseconds,blocking fire risks at the source. Simultaneously,via inverter cluster control technology,other combiner boxes in the same blockare synchronously shut down in tandem to prevent any fault contribution.

Terminal Overheating Protection System

A high-precision temperature sensor network is deployed to monitor inverter terminal temperatures in real-time. Upon detecting abnormal temperatures,the corresponding circuit is immediately disconnected,eliminating fire risks caused by poor electrical contact.

Pioneering Grid-Forming Technology

In addition toinstalling energy storage systems,the grid-forming capability of the PV system is also critical to the stable operation of projects. Equipped with Sungrow's solar grid-forming technology,the 1+X 2.0 Modular Invertercan reliably operate in diverse grid conditions. When facing grid fluctuations,the inverterenables equivalent inertia support within five milliseconds,rapidly stabilizing grid frequency. It withstands transient overvoltage up to1.8 times the rated voltage which meets the highest industry benchmark and automatically adapts to both strong and weak grids,ensuring stable system operation under all grid conditions.

Grid-forming can be used to provide power during plant construction and commissioning by forming a microgrid within or across several inverter blocks. This eliminates the need for diesel generators,accelerates the lead time of grid connection,and maximizes power generationfor the lifecycle of the project.This technology was already applied in landmark projects including the Middle East and North America. For example,a 1GW project in the Middle Eastwith this technology achieved gridconnection30 days ahead of schedule,generating 2.9 million USD in additional revenue,significantly reducing the Levelized Cost of Energy (LCOE).

Energy storage is now essential in renewable power plants. Sungrow 1+X Modular Inverter 2.0 is compatible with both DC-and AC-coupled solar-plus-storage solutions,further increasing renewable energy utilization. The DC-coupled solution with this new product is more efficient and cost-effective,enabling an initial investment reduction ofover 10%and system conversion efficiency enhanced by 5% compared to traditional AC-coupled solutions. The solution enables 100% grid-forming capability based on AC capacity,making it a solar-plus-storage generator.

Furthermore,the 1+X 2.0 Modular Inverter enables a significant CAPEX and OPEX slashby allowingcompliance with more PV modules per string design,MPLC advanced communication technology,larger blockdesigns,intelligent Medium Voltage disconnection,and more flexible O&M. Due to these functions,a 1GWsolar plantcan havecost savings of approximately 7.41 million USD.

"The 1+X 2.0 represents a paradigm shift for the utility-scale solarmarket," said Lee Zhang,Vice President at Sungrow. "From deserts to mountains,it empowers our customersto push boundaries while delivering outstandingreturns on investment. We're proud to drive the energy transition forward with solutions that marry innovation with sustainability,"Zhang added.
