SUNOTEC Orders 2.4-GWh Sungrow Batteries for European Solar Pipeline Expansion

• SUNOTEC orders 2.4 GWh of Sungrow PowerTitan 2.0 batteries for solar parks in Bulgaria and wider Europe, boosting grid stability and flexible clean power.

Bulgarian-German renewables specialist SUNOTEC has signed a landmark supply agreement for 2.4 GWh of battery-energy-storage systems (BESS) with Chinese power-electronics giant Sungrow. Deliveries of Sungrow’s modular PowerTitan 2.0 units will begin later this year and continue into 2026, equipping a cluster of large-scale solar parks in Bulgaria and several other European markets where SUNOTEC is currently active.

The package includes Sungrow’s SG350HX-20 string inverters and MVS medium-voltage stations for a flagship hybrid solar-plus-storage project—marking Sungrow’s first BESS deployment in Bulgaria. Several of the Bulgarian sites are backed by the national RESTORE support programme, positioning them among the country’s largest integrated PV-storage installations to date. 

SUNOTEC’s founder and CEO Kaloyan Velichkov said the deal underlines the company’s ambition to “build resilient, storage-enabled infrastructure that brings stability, sustainability and scale to markets across Europe.” By coupling high-efficiency modules with grid-forming batteries, the developer expects to deliver firm-power profiles that can participate in ancillary-services markets and shave peak-price exposure for corporate offtakers. SUNOTEC currently claims an 11 % share of Europe’s utility-scale solar construction market with more than 11 GW installed across 650 projects.

For Sungrow, the order strengthens its footprint in Central and South-East Europe—a region racing to add storage as renewable penetration rises. The PowerTitan platform integrates liquid-cooled lithium-iron-phosphate cells, multi-level safety circuitry and intelligent thermal management, enabling two-hour to four-hour configurations ideal for evening-peak shifting and grid-balancing services. Regional director Anastasios Gkinis said partnering with SUNOTEC “creates a powerful force to redefine the energy landscape” and accelerate Bulgaria’s transition from coal-heavy generation to low-carbon flexibility assets. 

Industry analysts note that large bespoke orders such as SUNOTEC’s are increasingly common as European developers look to lock in supply ahead of expected tightness in the global battery market. With EU grid codes tightening and capacity-market reforms rewarding fast-response storage, integrated PV-plus-storage portfolios are becoming the new norm rather than the exception. SUNOTEC aims to commission its first Sungrow-equipped battery blocks in early 2026, with the remainder following in phased intervals through 2027.
