01 — Product Line

Three platforms.
One architecture.

Every cabinet shares the same AC-side independent design, liquid-cooled thermal management and cloud-edge O&M stack — scaled to match the load you actually have.

02 — Engineering

Built to run hard,
and run long.

Six design decisions that show up on your P&L: fewer conversions, cooler cells, fewer site visits and a faster path from delivery to energisation.

Precision liquid cooling

Cell temperature delta held within 5 °C across the whole pack, extending usable life and flattening degradation.

≥ 98% round-trip efficiency

High-efficiency conversion with no parallel operation, so every stored kilowatt-hour comes back out.

AC-side independent

Each cabinet stands alone on the AC bus — no master-slave coupling, no single point of failure, easy expansion.

Three-level fire safety

Cell, pack and cabinet protection with perfluorohexanone suppression and a water fire-fighting interface.

Cloud-edge O&M

Local monitoring plus a cloud platform with predictive alerts — 24/7 visibility without site visits.

IP55 cabinet, IP67 packs

Deploy indoors or outdoors in dust, humidity and coastal air without adding a shelter structure.

03 — Deployment

From container to
commissioning, faster.

A lightweight monolithic structure, bottom cable entry and a factory-assembled cabinet mean less site preparation, fewer trades on site and a shorter window between delivery and first discharge.

  • Single-cabinet delivery — no on-site battery assembly
  • Bottom inlet / bottom outlet cabling for clean routing
  • RS485 / CAN / Ethernet integration with existing EMS
  • Bilingual documentation and O&M training for local teams
How we work
04 — Applications

One asset.
Several revenue streams.

The same cabinet can peak-shave in the morning, absorb solar at noon and hold the site up through an outage at night — stacked services from a single installation.

01

Commercial & Industrial

Cut peak demand charges and optimise time-of-use consumption for factories, cold stores and logistics hubs.

02

Renewable Integration

Smooth intermittent solar and wind output, prevent curtailment and keep the grid connection stable.

03

Peak Shaving & Frequency Regulation

Provide grid support services and unlock ancillary revenue alongside your own consumption savings.

04

Backup Power

Bridge outages without diesel start-up delay, protecting sensitive processes and production continuity.

05

Microgrid & Off-Grid

Independent power for islands, mining and remote sites, displacing diesel generation and its logistics.

06

Dynamic Capacity Expansion

Add cabinets as load grows — AC-side independence means expansion without re-engineering the plant.

05 — Assurance

A warranty that
matches the asset life.

A 10-year limited system warranty, an 80% capacity retention guarantee after 6,000 cycles, and a 48-hour on-site service commitment — backed by a decade of spare-parts availability.
