Sungrow wins 7.5 GWh Masdar order for Abu Dhabi 24/7 solar-storage project

Sungrow has signed an agreement with Abu Dhabi-based Masdar to supply 7.5 GWh of battery energy storage systems for the RTC 1 Plant (North) project in the United Arab Emirates, adding another large Middle East order to the Chinese inverter and storage supplier’s pipeline.

Under the agreement, Sungrow will provide PowerTitan 3.0 liquid-cooled energy storage systems, as well as 2.6 GW of PV inverter solutions. The equipment will support Masdar’s round-the-clock renewable energy project in Abu Dhabi, which combines 5.2 GW of solar PV capacity with 19 GWh of battery storage. The project is being developed by Masdar and Emirates Water and Electricity Co. (EWEC).

Masdar has described the project as the world’s first giga-scale 24/7 solar and battery storage project. It is designed to deliver up to 1 GW of baseload renewable power every day by using oversized solar generation and large-scale storage to smooth output. The project is expected to start operation in 2027.

Sungrow said the project will deploy more than 1,000 PowerTitan 3.0 systems, which are equipped with 684 Ah stacked battery cells, with a total deployment of 3.44 million cells. Each BESS is designed around an eight-hour charging and 16-hour discharging cycle to support continuous renewable power delivery. The system uses AC block design and cluster-level management, which Sungrow said are intended to improve safety, efficiency and operational availability.

The PowerTitan 3.0 platform incorporates a fully liquid-cooled silicon carbide power conversion system with maximum efficiency of 99.3% and system round-trip efficiency of 90%, according to Sungrow. The company said the system can operate at temperatures of up to 55 ℃ without derating, a key requirement for desert conditions in the UAE.

The order is also linked to Sungrow’s increasing efforts for larger-format storage technology. The company launched PowerTitan 3.0 in 2025, offering 10-foot, 20-foot and 30-foot configurations for two- to 12-hour storage applications. The 30-foot version supports up to 12.5 MW/50 MWh per AC block and uses up to 684 Ah stacked battery cells.

Masdar is one of the UAE’s major clean energy developers. The company says it has developed and partnered on more than 65 GW of clean energy projects across more than 40 countries and is targeting a 100 GW portfolio by 2030. Sungrow said it had installed more than 1,000 GW of power electronic converters worldwide by the end of 2025. The Abu Dhabi deal follows several large Middle East orders for Sungrow.

In July 2024, the company signed three storage contracts with Saudi Arabia’s Algihaz Holding totaling 7.8 GWh, covering projects in Najran, Madaya and Khamis Mushait. Sungrow also previously agreed to supply 536 MW/600 MWh of storage and 2.2 GW of PV inverter solutions for Saudi Arabia’s NEOM Green Hydrogen Project.
