Munich, Germany / June 19, 2024 - A significant amount of visitors at Intersolar Europe 2024 witnessed the unveiling of Kehua's latest technology S³-EStation 2.0 Liquid-Cooling BESS and comprehensive photovoltaic (PV) and energy storage solutions for diverse scenario applications. As a Tier 1 energy storage supplier globally and the world's leading provider of PV and ESS solutions, Kehua is showcasing its high-security R&D achievements and high-performance energy storage solutions in an all-round way.

S³-EStation PremiereThe spotlight was on Kehua's newly showcased S³-EStation 2.0 5MW/10MWh intelligent liquid-cooling energy storage system. The solution integrated a 5MWh liquid cooling battery energy storage system and a 5MW MV Skid, supported by over 100 patents and featuring three key technological highlights: 

SAFE: The 5MWh liquid-cooled container is equipped with multi-point monitoring for rapid fire alarm activation. The co-operation of 3-level fire protection system, i.e., pack-level modular fire distinguish device, cluster-level aerosol fire distinguish and container-level compartment sprinkler fire protection ensures the safety and reliability of the solution.
SMART: Kehua developed cluster-level optimizers to maximize the capacity of each cluster and enhance the availability of the battery energy storage system. With a wide controllable SCR range, black start capability, and high tolerance to phase angle changes, this solution provides robust support to global power grids.
SIMPLE: Through increased battery capacity and structural upgrades, the EStation 2.0 achieves a 45% density improvement, effectively reducing the space requirements of the energy storage system. Factory pre-assembly and testing provide a better on-site installation experience. Standard-sized transport facilitates simpler and more cost-effective equipment transportation.  

Zero-carbon Utility Solution
In addition to large-scale energy storage solution, Kehua presented a diversified utility-scale photovoltaic solution with superior ROI. The new generation 350kW string inverter showcased at the booth demonstrated outstanding performance in power generation, safety, reliability, and adaptability. With a 12/15 MPPT design and a maximum efficiency of 99.02%, it significantly increases power generation. With an IP66 protection rating and optional C5 protection, it delivers enhanced value in various environments such as deserts and islands.


Zero-carbon C&I Solution
For commercial and industrial energy storage applications, Kehua's S³-EStore C&I liquid-cooling ESS, continues to attract great attention. The system combines active safety, streamlined flexibility, and intelligent efficiency by integrating PCS, BMS, batteries, fire protection, and liquid cooling systems in a compact 1.3m² footprint. With an overall efficiency of up to 90.2%, cluster-level fine management, simple delivery and installation, and flexible expansion capabilities, it meets diverse requirements for commercial and industrial parks, further enhancing the profitability of commercial and industrial energy storage. At present, the system has been widely used in Europe and Latin America. 

The SPI125K-B-X2 and SPI60K-B-X2 string inverters achieve an IP66+C5 protection rating, providing a secure and reliable photovoltaic solution for commercial and industrial property owners. With intelligent IV scanning functionality, they accurately detect module anomalies, offering property owners convenient and straightforward operation and maintenance, saving time and effort. Zero Carbon Residential SolutionsIn the zero-carbon residential display area, Kehua presented the S³-iStoragE3 series all-in-one residential ESS and SPI25K-B-X2 string inverter. The S³-iStoragE3 continues the elegant and minimalist design for the household family, winning the prestigious IF Design Award. It is safe and reliable, operates quietly, and features intelligent management through an app for an exceptional user experience. 


The compact SPI25K-B-X2 string inverter surpasses the industry average in size and weight, with comprehensive lightning and leakage protection for safe electricity usage at home.
