Key benefits
- High‑capacity 48 V LiFePO₄ modular battery stack delivering up to 48.3 kWh of storage in a single, IP65‑rated enclosure, suitable for indoor or outdoor installation in UK commercial and industrial sites.
- Scalable design built from multiple 16.1 kWh modules with a top‑mounted control unit, allowing you to expand from smaller stacks up to around 1.23–1.28 MWh across parallel stacks.
- Engineered for demanding environments with integrated heating, IP65 enclosure and built‑in fire suppression, providing robust safety and long service life (up to 8 000 cycles, 15‑year design life).
C&I projects
The Fogstar Energy IP65‑Rated 48 V 48.3 kWh Modular Battery Stack is a LiFePO₄ energy storage system designed for commercial, industrial and large residential applications requiring high‑capacity, low‑voltage storage. Each stack is assembled from three 16.1 kWh 51.2 V modules, managed by a single top‑mounted control unit and housed in an IP65‑rated enclosure with integrated safety features. Multiple stacks can be paralleled to support large hybrid inverter systems, EV charging, process loads or off‑grid power solutions where reliability and scalability are essential.
Key features
- 48.3 kWh per stack: modular 48 V system built from three 16.1 kWh LiFePO₄ battery modules, managed as a unified battery by the top‑mounted control unit.
- IP65‑rated enclosure: weather‑resistant housing with integrated heating, suitable for indoor plant rooms and sheltered outdoor locations in UK climates.
- High performance: up to 8 000 cycles at ~91 % DOD, 300 A maximum discharge and 150 A maximum charge current, supporting high‑demand LV inverter systems.
- Built‑in fire suppression: integrated fire suppression unit within the stack for enhanced safety in commercial and industrial environments.
- Scalable architecture: multiple stacks can be paralleled to reach total storage up to around 1.23–1.28 MWh, ideal for phased deployments and future expansion.
- Compatibility: the battery stack is compatible with most leading low-voltage 48 V hybrid and off-grif inverters - LuxpowerTek, Solis, Sunsynk, Victron (Requires a VE.Can to CAN cable) and others.
