Commercial Energy Storage System KSTAR BluePulse Series KAC125DH-BC233DE
The KSTAR BluePulse series, model KAC125DH-BC233DE, is an advanced commercial energy storage solution that combines a high-performance hybrid inverter with an external battery cabinet. The system is designed for safety, reliability, cost-effectiveness, and ease of use, offering integrated BMS/EMS management and remote monitoring capabilities. It is an ideal choice for businesses seeking an efficient way to manage energy and optimize expenses.
Key features of the KSTAR BluePulse KAC125DH-BC233DE system:
- Comprehensive high-power solution: The system integrates the KAC125DH hybrid inverter with a nominal AC output of 125 kW (up to 138 kW) and efficiency up to 98.5% with the external BC233DE battery cabinet providing a total capacity of 233 kWh (CATL LFP cells, 90% DoD).
- Top-level safety and reliability: Equipped with CATL LFP battery cells, a dual fire suppression system, a 1+1 redundant design, and numerous inverter protections, including reverse polarity protection and DC/AC surge protection.
- Cost-effective and scalable design: Expandable as needed (“Save CapEx, Expanding as Required”) and featuring an efficient, energy-saving HVAC system for the battery cabinet to ensure optimal operating conditions.
- Easy installation and user-friendly operation: The system comes factory pre-installed for quick on-site assembly. The integrated BMS/EMS is suitable for various applications, and cloud-based monitoring and control are intuitive.
- Outdoor durability: The battery cabinet (BC233DE) is suitable for outdoor installation (IP54 protection rating, corrosion resistance level C4, cooled by air conditioning), while the inverter (KAC125DH) has an IP66 rating.
- Advanced grid and off-grid capabilities: The inverter supports on-grid operation with adjustable power factor and off-grid operation (requires an external STS250D transfer switch) with a nominal output power of 125 kW.
Who is this a good choice for?
The KSTAR BluePulse KAC125DH-BC233DE energy storage system is an ideal solution for medium and large enterprises, commercial facilities, and industrial sites aiming to optimize energy use, increase energy independence, and reduce operating costs. Thanks to its scalability, high efficiency, advanced safety features, and off-grid capability, this system is well suited for applications that require reliable and efficient energy management, including peak shaving and backup power supply.
