BEIJING, July 16 (Reuters) - China's photovoltaic inverter manufacturer Sungrow Power Supply said on Tuesday it has signed an agreement with Saudi Arabia's Algihaz Holding for an energy storage project with a capacity of up to 7.8GWh.

The project, expected to be delivered this year, will improve the stability and reliability of Saudi Arabia's power grid and help realise Saudi Vision 2030, the company said in a statement. (Reporting by Ella Cao, Siyi Liu and Ryan Woo; Editing by Jacqueline Wong)
