Sungrow Redefines Utility-Scale Solar Solutions with Launch of 1+X 2.0 Modular Inverter

HEFEI, China, April 15, 2025 /PRNewswire/ -- Sungrow, the global leading inverter and energy storage system provider, unveiled its groundbreaking 1+X 2.0 Modular Inverter for utility-scale applications during the 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.

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
Engineered to be robust in harsh conditions such as scorching heat in the Middle East, the 1+X 2.0 Modular Inverter integrates high-power-density semiconductors, a high-efficiency heat exchanger as well as a dual-cycle thermal management system to ensure optimized heat dissipation, maintaining stable operation without derating when the temperature reaches up to 52 degrees Celsius.

Its IP66 protection 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—most PV 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:
