Sungrow PowerStack – Energy That Works for Your Business
Publication date: 05. February 2026
Boost Efficiency and Optimize Costs with PowerStack
In today’s business environment, where efficiency, reliability, and cost optimization determine success, companies need solutions that truly work. Energetik energija d.o.o. provides access to Sungrow’s advanced energy storage systems, helping you store energy, reduce costs, and increase energy independence.

The Sungrow PowerStack is an all-in-one energy storage system designed specifically for commercial and industrial applications. It combines a lithium-ion battery, Power Conversion System (PCS), advanced Battery Management System (BMS) and an integrated fire protection system, delivering safe, intelligent and efficient energy storage in a compact, modular design.
The system is available in scalable configurations: ST225kWh (225 kWh to 2.25 MWh) and ST445kWh (445 kWh to 4.45 MWh), allowing projects to grow as energy needs evolve. PowerStack supports peak shaving, load shifting and maximising self-consumption, helping companies actively lower energy costs and improve energy efficiency.
Key Benefits for Users – Sungrow PowerStack
Self-Consumption
- Maximizes the use of PV energy and the battery to cover your consumption.
- How it works in practice: the system first uses energy from solar panels; if PV is insufficient, it draws from the battery; only then it uses the grid.
- Price-based optimization: charge the battery when electricity is cheapest, discharge when it’s most expensive.
- Peak Shaving: reduces peak loads – if consumption suddenly spikes, PowerStack draws energy from the battery to avoid high grid costs.
Time Plan and Time-of-Use Strategy
- Allows scheduling battery charging and discharging according to the most favorable electricity prices.
- The system can charge the battery at night or during low-tariff hours and discharge during peak prices, saving money.
- Flexible scheduling: separate plans for weekdays, weekends, or even monthly, matching seasonal consumption patterns.
- Automatic switching: the system seamlessly switches between self-consumption and scheduled operation to ensure optimal economic efficiency.
Forced Mode
- Enables manual charging or discharging, e.g., during maintenance or specific needs, to align with your settings.
VPP Dispatch and Remote Fixed Value
- Receives commands from virtual power plants or other control platforms to optimize active and reactive power – excess energy can be sent to the grid or used to charge the battery according to grid requirements.
Power Factor Control
- Reduces extra costs caused by poor power factor.
- Automatically adjusts the reactive power of batteries and PV to avoid additional grid charges.
Off-Grid Operation
- Provides power even during grid outages.
- Manages battery charging/discharging and can activate a diesel generator or PV system as needed to maintain stable energy supply.
PowerStack is more than a battery – it’s a complete energy strategy
