Description
Built for indoor commercial installs, this 40kWh cabinet delivers the same modular LFP storage as the outdoor version, sized for mechanical rooms and covered spaces.
Key Features
- Indoor-Rated Enclosure: IP20 protection suits mechanical rooms and other covered installation spaces.
- Modular Cabinet Design: Combines with additional units for expanded capacity as project demand grows.
- Tier 1 LFP Chemistry: Lithium Iron Phosphate cells deliver high thermal stability and long-term reliability.
- Advanced BMS: Real-time monitoring, balancing, and protection across the full battery pack.
- Long-Term Warranty: 10-year coverage with 70% capacity retention at 8,000 cycles.
An 8-rack configuration delivers 40.96 kWh of usable nominal energy, built around a 1P128S pack layout at 100Ah nominal cell capacity.
Nominal voltage runs at 409.6 Vdc, operating within a 358.4-460.8 Vdc range to match compatible eSpire Nano inverters.
Discharge and charge current tops out at 100A, giving this unit enough headroom for peak shaving and demand charge management.
