More product details
Supplying 8–10 kW continuous power on low-voltage 48 V systems requires massive current handling. The FB-L-16 incorporates heavy copper busbars and high-capacity cells to sustain 200 A continuous discharge.
- 16S series LFP cell string provides 51.2 V nominal (40.0–56.8 V operating range).
- Delivers up to 10.0 kW continuous DC power into 48 V hybrid and off-grid inverters.
- Internal pre-charge soft-start circuitry prevents inverter capacitor inrush tripping during startup.

What is the continuous discharge power capability of the FB-L-16 cabinet?
Full 10.0 kW continuous DC power (51.2 V @ 200 A). The cabinet's internal busbars and BMS are rated for 200 A maximum continuous discharge ($51.2\text{ V} \times 200\text{ A} \approx 10.2\text{ kW}$), allowing it to power large 8 kVA to 10 kVA low-voltage inverters under full load without current throttling.
