IronVault BESS Commercial Battery Energy Storage
Scalable lithium-ion battery energy storage for peak shaving, load shifting, and grid services.
Overview
The IronVault BESS is a containerized, turnkey battery energy storage system designed for commercial and industrial demand charge reduction, renewable energy time-shifting, and grid ancillary services. Each 20-foot ISO container houses up to 2.5 MWh of lithium iron phosphate (LFP) cells with integrated battery management, thermal management, fire suppression, and a bi-directional inverter. IronVault systems can be paralleled for multi-megawatt installations and are managed through NanoGrid IQ for optimal dispatch.
Key Features
- Lithium iron phosphate (LFP) chemistry for 6,000+ cycle life at 80% depth of discharge
- Integrated bi-directional inverter with grid-forming and grid-following modes
- Active liquid cooling maintaining cells within +/- 2 C temperature uniformity
- UL 9540A-tested fire suppression with aerosol and clean agent dual system
- Modular, paralleled architecture from 250 kWh to 100+ MWh
- NanoGrid IQ integration for AI-optimized dispatch, peak shaving, and arbitrage
