Bluetti AC300 + B300K Portable Power Station

Overview

The Bluetti AC300 + B300K is a modular portable power station system featuring 3,072Wh of LiFePO₄ capacity expandable to 12,288Wh with up to 4x B300K battery modules. The AC300 inverter delivers 3,000W continuous output (6,000W surge) with 2,400W AC and solar input, supporting dual-unit configurations for 240V split-phase. With 3,500+ cycle life, modular hot-swappable batteries, TT-30R RV port, wireless charging, and full Bluetti App control, it is designed for scalable whole-home backup, RV living, and professional off-grid applications.

Key Highlights
  • Modular system with 3,072Wh base capacity expandable to 12,288Wh (4x B300K batteries) and support for dual AC300 units for 240V split-phase output up to 6,000W continuous
  • 3,000W pure sine wave inverter with 6,000W surge capacity, 4 AC outlets, and TT-30R RV port — powerful enough for full-size refrigerators, well pumps, and power tools
  • Ultra-fast 2,400W AC input recharges the B300K from 0-80% in approximately 1 hour, with 2,400W MPPT solar input supporting up to 8x 300W panels for comprehensive off-grid recharging
  • Modular hot-swappable battery design allows for capacity expansion without downtime — the AC300 inverter runs independently while extra B300K batteries can be added or swapped as needed
  • Bluetti App with Wi-Fi/Bluetooth provides real-time monitoring, custom charging schedules, and remote control, with generator input support for dual-fuel recharging in extended off-grid scenarios
