CXS-5MWB

5 MWh Stationary DC Block

A 5,015.9 kWh / 2,507.5 kW DC, liquid-cooled stationary battery DC block in a single 20-ft ISO container. Pairs with any utility-scale external PCS for grid services, microgrids, industrial backup and remote regions that are grid-isolated.

−40 / +50 °C

Engineering Brief

Safe and Reliable

Pairs with any utility-scale external PCS for peak shaving, frequency response, capacity firming and black-start service — no inverter inside the container.

Endure

Closed-loop liquid cooling, IP55 container / IP67 pack ingress, multi-stage suppression and a −40 / +50 °C envelope for continuous duty.

Secure

Optional hardware QRNG signs comms and firmware — closing the entropy gap that breaks classical control and monitoring PRNGs.

Mission Use Cases

Grid Services

Peak shaving, frequency response, capacity firming and black-start service via an external utility-scale PCS skid.

Industrial Backup

High-availability backup for data centres, ports and heavy industry — 14 days from pad pour to first dispatch.

Remote Regions

Sovereign 5 MWh-class storage for diesel displacement and renewable firming in microgrids.
