KSTAR, a worldwide leader in energy storage innovations, participated strongly at 2025 SNEC ES+ in Shanghai, displaying varied innovative technologies that can serve residential, commercial, and utility scale applications. The company showcased its commitment to safe, reliable, and scalable energy storage technology to support the ever-increasing demand for sustainable energy across the globe.

Cutting-Edge Solutions for Commercial and Industrial Applications

At the expo, KSTAR introduced the KAC125DP2-BC233DE2, part of its premium ‘BluePulse’ Series for commercial and industrial (C&I) facilities. This integrated energy storage solution uses high-performance CATL battery cells and dual fire protection for safety and long-term reliability. Notably, the STS (Static Transfer Switch) built into the BluePulse Series enables automatic on/off-grid and genset control to provide uninterrupted service, even during outages - a critical need for business.

Scalability is another important facet to the BluePulse Series; the system has the capability to operate with up to six units off-grid, and up to 20 units on-grid. The ability to scale up the BluePulse system makes it the right choice for C&I facilities that will be expanding their energy footprint. Overall, the safety, reliability, and scalability make the BluePulse Series an ideal energy storage systems for businesses.

Homeowners Benefit from the BlueSpark Series

KSTAR showcased the ‘BlueSpark’ Series as a hybrid energy solution for residential customers, which ultimately works to balance the grid's dependence on backup power. It is available in both single-phase (3.68–6 kW) and three-phase (4–12 kW) versions and features advanced battery cells that are covered by a 10-year warranty of performance.

It supports on-grid and off-grid parallel connection of families can have electricity in the event of an outage. In addition to providing power during outages, however, another added benefit of a hybrid system supports fewer hours off-grid. The BlueSpark Series is designed for households that want a truly sustainable, flexible, and reliable alternative for a hybrid energy system.

Knight Series Inverter Expands Residential Options

KSTAR showcased the ‘Knight’ Series hybrid inverter, which can support both lead-acid and lithium iron phosphate (LFP) batteries. The inverter offers wide PV input and AC input ranges to allow for greater compatibility between different household systems. The built-in diesel generator ensures reliable backup power, while the inverter can connect four parallel units, allowing homeowners to increase their systems as their energy needs expand.

Utilities-Scale

For large renewable energy projects, KSTAR introduced the GSE3600D PCS and GSE7200D-MV containerized energy storage systems. With three-level topology, the systems achieve over 99% efficiency and ultra-fast charge/discharge switching at 30ms, both necessary features when frequency regulation is required.

The systems include a four-port dual-network redundant design to ensure stable data transmission throughout the system. The integrated medium voltage design works with dry and oil transformers, offering configuration flexibility. The systems are designed to withstand extreme conditions, including high altitude, temperature, humidity, and other environments such as high salt mist and silica. These systems are built to last for utility-scale energy projects.

A Vision for Reliable and Scalable Energy

KSTAR’s exhibit at SNEC ES+ 2025 demonstrates its devotion to developing energy-storage systems that are safe, scalable, and suitable for use in residential, commercial, and industrial applications. By harnessing advanced technology and design, KSTAR enables businesses and households to attain reliable and sustainable energy management in a world that is more aware of energy consumption.
