System overview

A complete C&I storage block, ready to deploy.

Legend 112C consolidates 112 LiFePO4 cells in a 1P112S configuration into a single outdoor cabinet. DC/AC split design, integrated thermal management, aerosol fire suppression, and an IP55 enclosure — sized for car-park, micro-grid, peak-shaving, and behind-the-meter installations.

Built to run, outside, for a decade.

IP55 enclosure, C3 corrosion grade, < 75 dB acoustic profile, and a charge window that opens at 0 °C and discharges down to −20 °C.

High-efficiency energy management

High-efficiency energy management

Adaptive thermal-management algorithm holds cells inside the optimal SOC band, lifting round-trip efficiency and protecting capacity over 11,000 cycles.

Safety & reliability

Safety & reliability

Aerosol-based fire-suppression, integrated temperature and smoke sensors, and a steel enclosure rated to C3 corrosion environments. Five-layer protection chain across temperature, charge and current.

5Layer protection chain

Aerosol Fire Extinguishing

The cabinet is equipped with an integrated aerosol fire extinguisher. Upon detecting high temperature, the system activates automatically and fully suppresses the fire within 5 seconds — minimising risk and protecting the installation without manual intervention.

5sec auto-suppression

Intelligent Air-Cooling System

The cooling system activates automatically, drawing heat away from the cell stack. Cooling stops once the maximum cell temperature returns to 25 °C, reducing energy draw and extending fan life.

Inside the cabinet

Six layers, one enclosure.

The Legend 112C is a vertically integrated stack — the battery, BMS, DC bus, cooling, fire-suppression and comms-gateway are designed and tested as a single unit, not assembled on site.
