PowerStack ST455kWh-110kW-4h is an advanced, high-efficiency energy storage system designed for commercial and industrial (C&I) applications with liquid cooling and thermal power management powered by artificial intelligence for optimal performance.
This battery storage system is engineered for seamless integration across transport, installation, and O&M. Its fully integrated design with pre-installation and pre-commissioning features significantly reduces on-site setup time and operational costs.
The energy storage system charges and discharges energy within a 4-hour period (0.25C Rate), allowing for flexible scalability, and comes with a 5-year warranty.
The PowerStack by Sungrow is a compact and modular energy storage system. Thanks to its all-in-one design, it integrates the battery, inverter, and energy management system into a single, easy-to-install unit.
PowerStack components come pre-assembled inside a cabinet: PCS: SC110CX Inverter-Charger, Liquid Cooling Unit, Battery Rack with 4 lithium-ion battery units, and Power Distribution Box containing the fire suppression system (FSS).
Sungrow PowerStack Commercial & Industrial Energy Storage System is devised to support multiple business models like demand response, emergency backup, peak shaving, and grid support, enhancing overall energy management and potentially reducing costs.
The ST455kWh-110kW-4h is ideal for applications requiring longer energy discharge durations, such as load shifting, peak shaving, or supporting operations during extended outages.
Thanks to the system flexible design, ST455kWh cabinets can be installed without separation spaces, optimising the use of available area. Up to 10 cabinets can be connected per installation, allowing capacity expansion up to 4.55 MWh for larger projects.
Whether placed face-to-face, back-to-back, or side-by-side, it perfectly caters to the unique needs of commercial and industrial applications where space usage is critical.
PowerStack is an all-in-one, highly integrated storage solution which is designed for quick connection and commissioning minimising on-site installation work and operating costs.
All components come pre-assembled inside a cabinet; all plumbing is connected. On-site, the installation consists of basic work such as DC connections, groundwork, auxiliary power supplies, AC connection, and cold and hot commissioning. The complete commissioning is done in a maximum of two days.
Other features:
Equipped with an intelligent Energy Management System (EMS), the PowerStack supports various functions such as Virtual Power Plant (VPP) integration and off-grid operation. It enables multi-dimensional dispatch across scenarios like photovoltaic (PV) integration, energy storage, charging stations, and diesel power generation control.
Utilising intelligent liquid-cooling temperature control, the system ensures balanced heat dissipation with a cell temperature difference of ≤2.5°C. This technology extends the system's lifespan and reduces auxiliary power consumption through AI-controlled thermal balance.
The PCS uses a forced-air cooling system.
Designed for extreme conditions, the system operates from -30oC to 50oC, and at altitudes of up to 3,000 meters.
ST455kWh-110kW-4h is designed for outdoor installation. With an IP55 rating, the system is protected against dust and water jets from all directions.
In addition, it offers a C5 corrosion resistance - a very high level of corrosion protection. The system is suitable for highly corrosive environments often found, for example, in places with high humidity, in industrial facilities, and in coastal areas.
Sungrow ST455kWh battery energy storage utilises five layers of safety protection, including multi-level fuse protection, multistage overcurrent protection, fast breaking and arc extinguishing, and over-temperature protection. The system has a separate fire-resistant compartment.
All these features are meant to contain and minimise the impact of any potential faults and to enhance the overall safety and reliability of the system.
Sungrow conducts comprehensive testing to ensure the whole system security. The tests cover different components of the system. Here are some of the tests performed by Sungrow:
Sungrow ST4555kWh-110kW-4h provides a three-layer fire safety design, accurate early warning of thermal runaway, timely fire protection, and anti-explosion.
The fire protection system layers:
The system includes advanced local and remote monitoring via the web or iSolarCloud app, providing real-time data and alerts for quick identification and troubleshooting.
Additionally, remote software updates are possible, significantly reducing operational and maintenance costs, and enabling a more streamlined and cost-effective energy management experience.
Sungrow PowerStack System is certified to the highest industrial standards. It complies with EU GDPR and holds SGS Certification, as well as IEC 62443 DEKRA International Safety Certification, ensuring excellent security and reliability.
