Pylontech US3000C 3.55kWh LiFePO4 Rack Battery (48V 74Ah)

The Pylontech US3000C is a 3.55kWh (48V / 74Ah) compact LiFePO4 rack battery — the C-revision (third generation) of Pylontech's best-selling US3000 module. Smaller and lighter than the US5000B while retaining the same 74A continuous discharge rating, the US3000C is popular for budget-conscious residential builds where capacity is added incrementally over time. Stack 1–8 modules per bus, mix with US5000B in parallel (Pylontech protocol handles mixed-capacity balancing). Full BMS integration: over-voltage, under-voltage, over-current, short circuit, and over-temperature protection per module and cell-level. CAN/RS485 master-slave protocol for automatic SoC balancing across stacked modules. Drop-in compatible with all US-series compatible inverters. Cycle life: ≥6000 cycles to 80%. Self-discharge <3%/month. Operating temp: −10°C to +50°C (charge), −20°C to +60°C (discharge). IP20, 19-inch 2U rack. Dimensions: 442 × 410 × 89mm. Weight: 22kg. UL 9540 listed.
