Kielce, Poland | February 18, 2025 — Xiamen Kehua Digital Energy Tech Co., Ltd (refered as Kehua), a global leader in high-reliability PV and energy storage solutions, unveiled a groundbreaking 20ft 5MW energy storage system (BCS5000K-C-HUD/T4) at ENEX 2025. Kehua's innovative full-Scenario PV and ESS solution has garnered significant industry attention with its breakthrough technological advancements. 
As a strategic breakthrough, Kehua’s BCS5000K-C-HUD/T4 delivers industry-leading 5MW power density in a standard 20ft container via its modular design integrating four BCS1250K-C-HUD converters. This 1500V all-in-one energy storage and power conversion system (PCS) combines compact engineering with effective scalability for utility-scale applications.
Equipped with grid-forming technology for equivalent inertia support (response time <20ms), black start capabilities, and VSG control, this solution is tailored for island microgrid and off-grid renewable energy scenarios. Prefabricated cabin architecture and intelligent parallel technology greatly reduce on-site installation time, while dual-mode string configuration (2/4 strings) ensures adaptability to diverse grid environments.
The BCS1250K-C-HUD energy storage converter (1.25MW) leverages advanced three-level topology, maintaining 1.1 times overload capacity even at 40°C ambient temperature. Its IP65 and C5 anti-corrosion certifications validate resilience in extreme conditions.
The 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, now globally deployed and recently honored with ENEX's Distinguished Energy Storage Award – a testament to its industry-leading innovation.
The SPI series industrial inverters ensure stable operation from -25°C to 60°C with C5 anti-corrosion and adaptive thermal management. The SPI125K-B X2 model resolves rooftop string mismatch issues via 9 MPPT tracks and ultra-wide 180-1000V voltage range.
The iStoragE3 all-in-one ESS features modular scalability, dual safety layers (physical isolation + distributed fire protection), and compact design, positioning it as the ideal choice for European households transitioning to zero-carbon living.
Kehua’s Poland Service Center delivers 24/7 lifecycle support through a 37-year-experienced engineering team and hybrid "online-offline" training programs empowering European partners. Anchored in Central and Eastern Europe, Kehua Tech will deepen the localized strategy to drive Europe's carbon neutrality by 2050.
Based on 37 years of experience in power electronic technology, Kehua has diversified solutions and rich project experience in the fields of photovoltaic, energy storage, micro-grids and integrated energy services. By the end of 2023, Kehua´s PV installation has exceeded 46GW and its energy storage installation has exceeded 15.2GW/8.2GWh globally. Presently, Kehua has become the world's third largest PCS supplier (S&P), a Tier 1 energy storage supplier and a Top 10 solar inverter manufacturer (BloombergNEF). As a reliable PV and ESS expert, Kehua is dedicated to enabling a zero-carbon lifestyle for individuals worldwide.
