Product Overview
2,764.8Wh LFP portable power station with 3,840W total AC output, two solar inputs rated at 1,200W each (12–60V DC, 20A each), and modular expansion support. Supports up to six compatible expansion batteries per unit. Includes a manufacturer-stated 20ms UPS function.
Additional Notes
The 2,300W standard AC input is distinct from the optional Hub A1 fast-charging configuration. BLUETTI advertises up to 58kWh system capacity and higher solar charging figures when additional equipment such as SolarX 4K is used; do not enter those accessory-dependent figures as the base unit's direct PV input. This is not a grid-tied microinverter system.
