Product Highlights

Higher Lifecycle Returns

Higher Lifecycle Returns

With a million-cycle lifespan and ultra-high C-rate, it is optimally suited for inertia response and primary frequency regulation requirements.

Cluster-Controlled, Integrated AC/DC Design

Cluster-Controlled, Integrated AC/DC Design

No DC circulating current, increasing system available capacity by 10%. Pre-installation reduces on-site commissioning time by 50%; side-by-side layout reduces footprint by 30%.

End-to-End R&D

End-to-End R&D

In-house production of core components; Max system RTE reaches 90%; Fully compatible with next-generation architecture.
