Description
The BLUETTI AC300 + 3×B300K is a powerful, expandable, and modular home battery backup system, purpose-built for off-grid living, whole-home emergency power, and high-demand applications. Featuring a 3,000W pure sine wave inverter (6,000W surge), the AC300 can run everything from air conditioners and refrigerators to power tools and medical devices—safely and silently.
Bundled with three B300K battery modules, this setup delivers a massive 9,216Wh of LiFePO₄ energy storage. The modular design allows further expansion up to 12,288Wh (4×B300K), giving users extended autonomy during outages or off-grid use. With 2,400W solar input support via dual MPPT, the system enables fast, efficient solar charging, while dual charging (AC + solar/generator) speeds up recharge times dramatically.
Control and monitor your energy usage in real-time via the BLUETTI App over Wi-Fi or Bluetooth. With 20ms UPS switchover time, this system guarantees seamless power during blackouts, making it the ultimate energy security solution for your home or mobile setup.
