The ARK-E 261 energy block adopts a modular design, highly integrating systems such as battery PACK, battery management, AC/DC conversion, thermal management, fire protection, and intelligent control to form an integrated energy storage solution. It has advantages such as high energy density, small footprint, high system efficiency, and multiple safety protections. It does not require foundation excavation, significantly reducing construction costs, and can be quickly deployed and operated stably. It is widely used in various scenarios such as peak shaving and valley filling in industry and commerce, virtual power plants, backup power supplies, and three-phase unbalance management.
Battery module-level fire protection, cabinet partition safety isolation, AI health management, 3S control and protection integration.
Storage depth 100%, AC-side conversion efficiency >90%, flexible deployment, elastic expansion.
Weak connection support, three-phase imbalance management, efficient AGC/AVC scheduling, and grid-connected/isolated mode switching
BCS comprehensive and all-round monitoring, modular design improves operation and maintenance efficiency, and cloud analysis significantly reduces operation and maintenance costs.
