  • Apex 300 with B300K battery and Hub D1

    Model: Apex 300 + B300K + Hub D1

    What differs
    Adds an expansion battery and the DC hub.
    Best for
    Buyers needing longer runtime and DC outputs.

    What differs
    Adds an expansion battery and SolarX 4K for higher solar input.

    An expansion battery for a compatible system, rather than an Apex station.
    Best for
    Existing owners adding stored energy.

Watch out

  • An AC-cable listing may duplicate the normal package: the standard box already includes that cable.
  • Hub D1 adds DC connections; a B300K adds storage. Neither alone is an Apex 300 station.
  • SolarX 4K is solar charging equipment, not a solar panel.
  • Check both panel count and wattage before selecting a solar bundle.
  • A Hub D1-only bundle is not the station; confirm Apex 300 appears in the box contents.

Why people pick it

  • LiFePO4 cells rated for 6,000+ cycles to 80%
  • NEMA 14-50R and TT-30R outlets for 240V loads and RVs
  • 2,400W of solar input over two inputs
  • Grows with up to six batteries per unit, and to multi-unit systems
  • 5-year warranty

Know before you buy

  • No USB or 12V ports without the separate Hub D1
  • Solar inputs are low-voltage (12-60V), so large arrays need parallel wiring
  • 83.8 lb before any expansion batteries
  • BLUETTI's certification line says 'UL' without naming the standard
