Kehua has taken part in the 2025 edition of Poland’s ENEX, unveiling a groundbreaking 20ft 5MW energy storage system.
The product delivers an industry-leading 5MW power density in a standard 20ft container via its modular design, integrating four converters. The 1500V all-in-one energy storage and power conversion system (PCS) combines compact engineering with effective scalability for utility-scale applications.
A 1.25MW energy storage converter leverages advanced three-level topology, maintaining 1.1 times overload capacity even at 40°C ambient temperature, with IP65 and C5 anti-corrosion certifications validating resilience in extreme conditions.
The company’s SPI350K-B-H X2 solar inverter optimizes plant performance through 6 high-current MPPT channels (75A each) designed for 182/210mm dual-format modules. Maintaining full output at 4,000m elevation, its intelligent protection system activates safety shutdowns while high-precision IV curve scanning enables module-level fault detection. The integrated self-cleaning mechanism ensures sustained operational efficiency by reducing maintenance interventions, delivering comprehensive solutions for high-elevation PV installations.
Kehua’s flagship S³-EStore 100K-B215 system integrates liquid cooling and pack-level aerosol fire suppression within a 1.3㎡footprint, achieving ±1.5°C temperature uniformity and sub-100ms grid-island switching. Its AI-driven energy management system employs dynamic load control and multi-period arbitrage algorithms to shorten ROI cycles, is now globally deployed and has received ENEX’s Distinguished Energy Storage award.
