Sigenergy has brought together 300 global energy professionals in the Bulgarian city of Burgas to explore the future of commercial and industrial (C&I) energy storage. A key highlight of the event was a visit to a landmark 20 MWh project in Malko Tarnovo, powered by the company’s modular C&I battery energy storage system (BESS), highlighting the scalability and real-world impact of next-generation storage technology.
In partnership with leading Bulgarian solar player Trakia MT, the system is installed on a solar farm featuring 90 Sigenergy C&I hybrid inverters combined with the SigenStack modular storage solution.
Sigenergy Founder and CEO Tony Xu commented: “Sigenergy’s mission is to accelerate the global transition to clean energy with innovative and scalable storage solutions. This project exemplifies how advanced battery systems can drive business growth and decarbonization across industries.”
SigenStack introduces a truly modular approach to C&I energy storage, replacing bulky containerized systems with stackable 12 kWh battery packs. With plug-and-play connectors and tool-free installation, the system eliminates complex wiring and the need for cranes and heavy machinery.
Thanks to this design, the entire 20 MWh system was installed in just 10 days and fully commissioned within 2 days. Trakia MT owner Galina Peycheva-Miteva confirmed: “The installation was incredibly smooth—more like assembling building blocks than deploying industrial infrastructure. This modular design is a game-changer for the C&I energy storage sector.”
Sigenergy’s C&I BESS supports 24/7 autonomous operation. With an IP66 rating for dust and water resistance, it delivers reliable performance across diverse environmental conditions.
Real-time monitoring via a cloud-based platform provides full visibility into system status, energy throughput and alarms, significantly reducing the need for on-site inspections. Maintenance is also streamlined: faulty battery packs can be replaced individually within two hours, without full system diagnostics or the intervention of an on-site technician.
