Fogstar Energy Server Rack Cabinet (15kWh)

Fogstar ESR51.2V Energy Storage Cabinets – Modular Battery Enclosure for Server Rack LiFePO4 Systems

Designed in the UK using premium-grade materials and innovative design techniques, the Fogstar ESR51.2V Energy Storage Cabinets offer a robust, scalable, and safe housing solution for your off-grid and backup power systems. Perfectly engineered for use with Fogstar ESR51.2V Server Rack Batteries, these cabinets are built to simplify installation, improve system longevity, and ensure professional-grade energy storage performance.

Available in two modular sizes – a 3 Rack Cabinet (15kWh) and a 6 Rack Cabinet (30kWh) – the system gives you the flexibility to expand your storage capacity as your energy demands grow.

Unlike conventional cabinet systems that connect batteries directly via terminals (leading to power imbalances), Fogstar cabinets are equipped with integrated thick nickel-plated copper busbars for even load distribution across all batteries. These internal busbars enable efficient, low-resistance parallel connections between rack batteries, improving overall performance and safety.
