KSTAR has exhibited at the 2025 edition of SNEC ES+ in Shanghai, showcasing its latest portfolio of energy storage solutions designed for residential, commercial and utility-scale applications.
Among highlights at the KSTAR booth was the ‘BluePulse’ Series KAC125DP2-BC233DE2. An all-in-one C&I energy storage system powered by CATL cells, it integrates dual fire protection for enhanced safety and long-term reliability, its built-in STS enabling automatic on/off-grid transition and genset control to provide uninterrupted power even during outages. The system also allows up to 6 units off-grid and up to 20 units on-grid, making it suitable for facilities with scaling energy needs.
For homeowners, KSTAR displayed the ‘BlueSpark’ Series, an all-in-one hybrid energy system available in single-phase (3.68–6 kW) and three-phase (4–12 kW) models, both versions featuring high-performance battery cells with a 10-year performance warranty and supporting on/off-grid parallel connection, enabling families to maintain power during outages while reducing dependence on grids.
The ‘Knight’ Series hybrid inverter was also on display, supporting lead-acid and LFP batteries, with wide PV and AC input ranges for greater compatibility. Its diesel generator design provides reliable backup, while support for 4 parallel units facilitates expansion for growing household energy needs.
On the utility side, KSTAR showcased its latest GSE3600D PCS and GSE7200D-MV containerized energy storage and transformer systems. The systems feature a three-level topology, offering over 99% efficiency and 30ms fast charge/discharge switching, essential for frequency regulation. With a four-port dual-network redundant design, the systems ensure stable data transmission, while an integrated medium-voltage design, compatible with both dry and oil transformers, provides configuration flexibility. Built with high environmental adaptability to withstand high altitude, extreme cold, heat, humidity, sand and salt-mist conditions, the systems provide long-term reliability for large-scale renewable projects.
