Product details

This modular, commercial-portable cabinet scales from 40 kWh to 372 kWh, packaging lithium-ion (LFP) battery packs, a BMS and liquid-cooling thermal management inside one outdoor-rated enclosure. Because the coolant loop maintains a uniform cell temperature, the system runs more efficiently, lasts longer through repeated cycles, and operates with an added safety margin. It's aimed at commercial and industrial (C&I) storage, solar self-consumption, peak shaving and off-grid use.

Design & Construction

The double-door housing holds modular battery racks cooled by an integrated liquid loop, a front control/HMI panel, status indicator lights and an emergency stop. A side vent grille keeps air moving and top lifting lugs simplify transport and installation. BMS communication runs over CAN, RS485 and Ethernet, so the unit links easily into an energy management system.

Applications

Commercial and industrial storage, solar-plus-storage pairing, peak shaving and load shifting, microgrids, EV-charging load support, and off-grid power for factories, campuses and remote sites.

Customisation Options

Capacity, internal configuration, grid connection mode, communication protocol and enclosure options can be adapted to the project's needs.
