Sunotec, Sungrow sign 2.4 GWh battery storage agreement

China-based Sungrow and Bulgarian-German company Sunotec have agreed to install 2.4 GWh of battery energy storage systems (BESS) in Europe.

Sunotec and Sungrow have signed a strategic agreement to deploy 2.4 GWh of battery energy storage systems (BESS) across multiple solar power projects in Europe, according to Sunotec.

The 2.4 GWh of energy storage capacity will support grid stability, enable better renewable energy integration, and enhance the reliability of solar parks developed and constructed by Sunotec throughout Bulgaria and wider Europe.

The portfolio includes several large-scale projects across Bulgaria, which will serve energy storage needs, the update reads. Some of the projects in the pipeline will be supported by funds under Bulgaria’s RESTORE national support program.

Velichkov: The next chapter of clean energy

Sungrow intends to supply its industry-leading PowerTitan 2.0 BESS, recognized globally as a top-tier solution for utility-scale applications, while the string inverter SG350HX-20 and Sungrow’s MVS will be used for a hybrid project (PV and BESS) in the portfolio. It would be the first BESS project in Bulgaria with Sungrow technology.

“The global energy transition depends not only on how much renewable power we produce, but on how intelligently we manage and store it,” Sunotec CEO Kaloyan Velichkov said.

The partnership with Sungrow, in his words, reflects shared ambition to lead the next chapter of clean energy – by building resilient, storage-enabled infrastructure that brings stability, sustainability, and scale to markets across Europe and beyond.

Gkinis: The deal is a cornerstone of the two companies’ mission to accelerate clean energy deployment in Bulgaria and Europe

According to Anastasios Gkinis, Regional Director of Sungrow for CEE, SEE and CIS, the collaboration with Sunotec is a cornerstone of his company’s mission to accelerate clean energy deployment in Bulgaria and across Europe.

“Combining Sungrow’s cutting-edge energy storage technology with Sunotec’s execution excellence, we create a powerful force to redefine the energy landscape in Bulgaria and support the region’s transition to a sustainable energy future,” he stressed.

Sunotec has delivered over 650 solar projects with a total installed PV capacity of 11 GW. As of December 2024, Sungrow has installed 740 GW of power electronic converters worldwide, the update reads.
