A 3.8 MWh utility-scale energy storage system has been successfully commissioned in Hungary under the coordination of SolarToday — a project that reflects our commitment to enabling next-generation grid stability across Europe. The system was designed as an integrated solution, combining JinkoESS batteries, the iNOVAT MV Skid, and the PowerKonnekt Energy Management System (EMS). The project investor, SolServices, is among the largest renewable energy developers in Hungary, with a project portfolio exceeding 1 GW.
Delivered Through International Collaboration
The project utilizes JinkoESS batteries, recognized globally on Tier-1 lists in both PV and energy storage categories for their high efficiency and proven operational reliability.
Lorenzo Paumgardhen noted:
“Jinko ESS has secured its position on the Tier 1 ranking for five consecutive quarters, thanks to our strong performance in the energy storage sector. We’re proud to be one of the few global companies to achieve Tier 1 status in both PV module and Energy Storage categories.”
The PowerKonnekt EMS, developed by iNOVAT, successfully meets the technical requirements for integration with the rapidly growing aFRR (automatic Frequency Restoration Reserve) markets across Europe — including real-time data processing, grid synchronization, and precise load balancing.
The system’s performance in the Hungarian deployment has demonstrated its capability to offer operational confidence to investors targeting dynamic ancillary service markets such as aFRR. This technological maturity enables effective and sustainable entry into Europe’s evolving flexibility markets.
Speaking on behalf of iNOVAT and PowerKonnekt, Sefa Keleş, Software Director, shared the following:
"From a technical standpoint, this project showcases our platform’s flexibility, interoperability, and capability to handle complex energy storage requirements under real-world conditions. Strategically, it reinforces the scalability and market-readiness of our solution, strengthening our position within the European ESS landscape."
SolarToday: Full-Scope Energy Storage Provider
Ömer Çiftçi, Head of BESS at SolarToday, shared his insights:
"With this project, we have proven our full-scope capabilities in energy storage — covering batteries, AC Skid, EMS, and engineering. From design to commissioning, and from battery integration to EMS configuration, every step was executed under our own technical supervision."
The system-level tests confirmed that the communication protocols between JinkoESS batteries and the PowerKonnekt EMS operated with high stability and accuracy, with all operational scenarios successfully validated.
This Project Sets a New Standard
Dr. Gábor Farkas, Managing Director (Chief of Legal and Regulatory Affairs) at SolServices, emphasized the broader significance of the project:
"What stood out most in this project was the shared commitment of all parties involved, their adherence to timelines, and the uncompromising professionalism they demonstrated throughout. This approach has established a new benchmark and standard for our future project developments."
A Strategic Reference Point in Europe
With this project, SolarToday has solidified its role not just as a product supplier, but as a strategic solution partner in the European energy storage sector. The company’s expanding portfolio in the region continues to grow through high engineering standards and strong collaborative partnerships.
As Europe accelerates its transition toward flexible and decarbonized grids, SolarToday remains committed to delivering bankable, scalable and technically robust energy storage solutions for every market it serves.
