Sungrow and Masdar Sign 7.5GWh Energy Storage System for Abu Dhabi's World First RTC Project
Sungrow, a provider of photovoltaic (PV) inverters and energy storage systems (ESS), has partnered with Masdar, a leader in clean energy, to supply solutions for the United Arab Emirates' first gigascale round-the-clock renewable energy project (RTC). The project, developed by Masdar and the Emirates Water and Electricity Company (EWEC), combines 5.2 gigawatts (GW) of solar PV capacity with a 19-gigawatt-hour (GWh) battery energy storage system to deliver baseload renewable energy at an unprecedented scale.
Under the agreement, Sungrow will provide 7.5 GWh of its PowerTitan 3.0 ESS, as well as 2.6 GW of PV inverter solutions, which are intended to enhance the operational reliability and efficiency of the project. The RTC aims to meet the increasing demand for uninterrupted clean power, serving various sectors, including energy-intensive industries, business operations, residential communities, and emerging digital infrastructure.
Set to commence operations in 2027, the RTC project is seen as a significant step forward in integrating solar PV and battery storage technologies at the utility scale. It is designed to deliver reliable clean energy around the clock while improving grid resilience and flexibility. The deployment will include over 1,000 PowerTitan 3.0 liquid-cooled ESS systems integrated with advanced PV inverter technologies to facilitate continuous power delivery and enhance grid stability.
The PowerTitan systems will operate on an 8-hour charging and 16-hour discharging cycle to maintain a flexible renewable energy supply. With an AC block design and rack-level management, the system aims to enhance both operational safety and efficiency. Notably, the system employs a fully liquid-cooled Silicon Carbide Power Conversion System (SiC PCS), achieving maximum efficiency of 99.3 percent and a round-trip efficiency of 90 percent. It is also designed to function in high-temperature environments, capable of operating at up to 55°C without performance degradation.
Once operational, the RTC project is expected to produce gigascale baseload renewable energy at a globally competitive tariff, serving as a model that could be replicated worldwide. Sungrow has been a pioneer in renewable energy technology for over 29 years, with more than 1,000 GW of power electronic converters installed globally as of December 2025. The company is recognized for its innovations that support clean energy initiatives around the world.
