Key electrical specs
Usable capacity: 15 kWh.
Nominal voltage: 51.2 V, operating range 44.8–57.6 V.
Recommended charge/discharge current: ≤150 A; max charge/discharge current 200 A for 15 s in the FLA48300 class.
Max output power: about 7.5 kW, recommended continuous power up to 5–6 kW for best life (same family spec as FLA48300).
Round‑trip efficiency: around 95% (LiFePO₄).
Chemistry, life and environment
Battery type: LiFePO₄ (lithium iron phosphate) for high safety and thermal stability.
Depth of discharge: ≥95% DOD supported.
Cycle life: ≥6 000 cycles at 25 °C, 80% DOD.
Operating temperature: discharge −20 °C to +55 °C, charge 0 °C to +55 °C.
Integration and safety
BMS & comms: built‑in smart BMS with CAN & RS485 for integration with compatible hybrid inverters and EMS platforms.
Parallel connection: typically 1–6 modules in parallel in the FLA48xxx family, giving up to 90 kWh total.
Safety features: internal protections for over‑/under‑voltage, over‑current, over‑temperature and short circuit; EU version includes enhanced safety features such as support for external fire‑suppression options per the EU datasheet.
Physical characteristics
Approx. weight: around 135–162 kg depending on enclosure variant.
Typical dimensions for this class: roughly 480–750 mm wide × 300 mm deep × 1 100–1 310 mm high, wall‑mount cabinet format.
