Sungrow PowerStack Reference: The Story of Successful BESS Projects Continues

Publication date: 10. August 2026

Our latest reference featuring 15 Sungrow PowerStack ST255CS-2H systems demonstrates that successful large-scale energy storage projects depend on more than choosing the right technology. Reliable equipment availability, competitive project conditions, efficient logistics and professional support are equally important when it comes to delivering projects quickly and successfully.

At Energetik, this is exactly what we aim to provide – supporting our partners from the initial inquiry and system selection through to equipment delivery and project implementation.



When Speed Matters in BESS Projects

For commercial and industrial energy storage projects, equipment availability can have a significant impact on the overall project timeline. Long lead times, complex logistics or insufficient technical support can quickly result in delays.

That is why Energetik focuses on providing partners with fast access to equipment and efficient support throughout project delivery.

Sungrow PowerStack is part of our portfolio of BESS solutions, backed by competitive commercial conditions, support with system configuration, technical documentation, logistics coordination and assistance before and during project implementation.
For larger projects, configurations and commercial conditions are prepared individually according to specific project requirements.
 

15× Sungrow PowerStack ST255CS-2H

The new installation in Slovenia consists of 15× Sungrow PowerStack ST255CS-2H systems, providing a total usable energy storage capacity of approximately 3.83 MWh.

PowerStack is Sungrow's solution for commercial and industrial energy storage (C&I), designed for projects where performance, safety, efficiency and system flexibility are essential.
Its modular design makes PowerStack suitable for a wide range of applications, from optimizing self-consumption and reducing peak demand to improving the utilization and management of renewable energy.
 

Why Sungrow PowerStack?

For C&I projects, PowerStack combines several important advantages:
  • Modular and flexible design for different project requirements
  • High efficiency and optimized energy management
  • Integrated system architecture that simplifies planning and implementation
  • Multi-level safety concept for reliable battery system operation
  • Designed specifically for demanding commercial and industrial applications
  • Technology from one of the world's leading providers of PV and energy storage solutions
 

Energetik – More Than Equipment Supply

Our involvement in a BESS project does not end with the sale of the system.

As a professional B2B distributor of solar and energy storage solutions, we aim to be a reliable partner for installers and EPC companies, including when projects become larger and more technically demanding.

We support our partners with system selection and configuration, technical documentation, quotations and project conditions, equipment availability, logistics coordination and technical support throughout project implementation.

Our goal is simple: to help our partners move from inquiry to implementation faster, more efficiently and with reliable support at every stage.
 

Building BESS Projects Together

This new PowerStack reference continues the story of energy storage projects we are delivering together with our partners.
Every project has different technical, commercial and scheduling requirements. That is why our approach goes beyond supplying a product – we work with our partners to find the right solution for each individual project.
