Product details

Rated at 90 kW / 266 kWh, this all-in-one cabinet combines lithium-ion (LFP) battery packs, a BMS and liquid-cooling thermal management inside a single outdoor-rated enclosure. The cooling loop maintains a consistent, optimal temperature across every cell, lifting efficiency, extending cycle life and improving safety. It's built for commercial and industrial (C&I) storage, solar self-consumption, peak shaving and off-grid use.

Design & Construction

Double doors open onto modular battery racks cooled by an integrated liquid loop, along with a front control/HMI panel, status indicators and an emergency stop. A side vent grille supports airflow and top lifting lugs make installation and servicing easier. The BMS communicates over CAN, RS485 and Ethernet for quick EMS integration.

Applications

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

Customisation Options

Capacity, configuration, grid connection mode, communication protocol and enclosure options can be tailored to project requirements.
