Core Highlights

Highlight 1

Modular Design · Parallel Cabinet Expansion

Each storage cabinet is a self-contained module. Multiple cabinets can be paralleled to scale capacity — the same architecture supports anything from a single cabinet to MWh-scale stations.

Highlight 2

Pre-Configured Peak/Valley Arbitrage Strategy

The EMS ships with a pre-configured time-of-use peak / valley arbitrage strategy — the client only needs to power on, and the system begins earning revenue immediately.

Highlight 3

Factory Cycle-Tested · Plug-and-Play On Site

Every cabinet completes full charge / discharge cycle testing before shipping. The on-site team only needs to position the cabinet and connect cables — true plug-and-play deployment.
