As new power systems evolve rapidly with high-penetration renewable energy integration, power grids are transforming from traditional load-following operation to interactive source-grid-load-storage systems, facing prominent challenges of low system inertia and insufficient voltage & frequency support. To address these pain points, EAST has launched the 215kW enhanced grid-forming string energy storage inverter. Powered by advanced grid-forming core technology and full liquid cooling design, it upgrades energy storage from passive response to active grid support, redefining grid-friendly energy storage solutions.
Active Grid Stabilization with Advanced Grid-Forming Core
Unlike conventional grid-following inverters that rely on grid synchronization and prone to instability in weak grid or off-grid scenarios, our inverter adopts self-developed grid-forming control algorithms. It independently establishes grid voltage and frequency benchmarks to deliver proactive system stabilization.
Supporting PQ, VF, SVG and VSG operation modes, it features millisecond-level power response and continuous high/low voltage ride-through capability, ensuring stable power supply even in off-grid conditions. Compliant with IEC 61850 protocol, it enables seamless integration with smart dispatching systems for efficient source-grid-load-storage coordination.
Full Liquid Cooling for High Efficiency & Ultimate Reliability
Equipped with a full liquid cooling system, the inverter boasts superior power density compared to air-cooled alternatives. It maintains full power output at 55°C, adapting to extreme high-temperature and dusty operating environments. With IP66 protection and C5 anti-corrosion grade, it resists moisture, salt fog and chemical corrosion for long-term stable operation.
Adopting three-level topology, it achieves a maximum conversion efficiency of 99% and full-power operation across 1000Vdc–1500Vdc DC voltage range, maximizing renewable energy utilization.
One-Cluster-One-Control for Higher Lifecycle Returns
The innovative one-cluster-one-control design eliminates inter-cluster circulating current and bucket effect thoroughly. Each battery cluster operates independently with full charge-discharge depth, significantly improving battery available capacity, boosting total lifecycle power generation, lowering LCOS (Levelized Cost of Energy) and maximizing economic benefits.
Slim & Flexible Design for Full-Scenario Deployment
Featuring a 155mm ultra-slim body and plug-and-play design, the inverter enables easy installation and low maintenance. It is perfectly compatible with 314Ah cell packs and supports multiple configurations including AC/DC integrated and boost integrated machines. Flexible multi-machine parallel expansion makes it ideal for new energy storage matching, independent energy storage stations, industrial park microgrids and other scenarios.
Breaking performance limits via grid-forming core and full liquid cooling technology, EAST 215kW grid-forming string energy storage inverter turns energy storage into a core pillar for grid security, stability and profitable operation.
