Fogstar Energy Server Rack Cabinet (30kWh)

Fogstar ESR51.2V Energy Storage Cabinet – 30kWh 6 Rack Server Battery Enclosure for Off-Grid Solar & Backup Systems

Designed in the UK with innovation and reliability in mind, the Fogstar ESR51.2V 30kWh Energy Storage Cabinet is a robust and professional-grade solution for housing server rack LiFePO4 batteries in off-grid, renewable, or commercial power installations. Built using the highest quality materials, this cabinet provides secure storage, improved thermal performance, and exceptional cable management.

Carefully engineered for seamless integration with Fogstar ESR51.2V rack batteries, this 6 rack version offers a total capacity of up to 30kWh. The cabinet has been designed to simplify installation and ongoing system maintenance while maintaining a clean, professional appearance.

Unlike traditional battery cabinets that connect batteries via positive and negative terminals—often causing imbalanced cells—this model features integrated thick nickel-plated copper busbars to evenly distribute current across all connected batteries. This parallel busbar system not only reduces resistance but also enhances safety, reliability, and performance.

• High-Capacity 6 Rack Enclosure (30kWh) – Designed for scalable energy storage with Fogstar ESR51.2V LiFePO4 rack batteries.
• Integrated Copper Busbar System – Ensures balanced load sharing and reduced power loss across cells.
• Vented Front Panel – Promotes natural airflow to regulate battery temperature and maximise lifespan.
• Optimised Cable Management – Circular cut-out ports at both the top and bottom of the cabinet for tidy cable routing and service access.
