Engineering Brief

Safe and Reliable

IP67 packs in an IP55 cabinet, aerosol fire suppression and multi-level electrical safety architecture.

Flexible

Modular 1P52S packs scale from a single cabinet to multi-cabinet C and I microgrid clusters via parallel connection.

Highly Integrated

Battery, PCS, chiller, fire-safety and controls factory-commissioned in one cabinet — six subsystems acting as one.

Smart Maintenance

Self-developed EMS with real-time state monitoring and intelligent charge/discharge management.

Mission Use Cases

Peak Shaving · Demand Response

Silent watch and primary power for FOBs. Cuts genset runtime up to 80 %, with ≤ 65 dB(A) acoustic signature and black-start capability.

PV Self-Consumption

Time-shift solar production for onsite self-consumption and grid-tied microgrid operation.

Military Edition

CADPAT-pattern ruggedised enclosure (Desert · Woodland · Urban) for forward deployments, tactical microgrids and field command.
