Generator set, power box BLUETTI AC500+2*B300K Home Battery Backup

Generators, Power boxes Bluetti AC500+2*B300K Home Battery Backup
The ultimate power solution for homes requiring maximum security and efficiency. The AC500 does not have a built-in battery, but acts as the heart of the system—functioning as an advanced 5,000W Pure Sine Wave inverter and controlling all charging and discharging. Working in tandem with BLUETTI B300K expansion batteries (each with a capacity of 5,529.6Wh), it allows you to build a flexible power system tailored to your needs. Connect up to 6 B300K units for a maximum total capacity of up to 16,588.8Wh, sufficient to power essential household appliances for days or even support an entire high-energy-demand home.

At the heart of the system is the automotive-grade LiFePO₄ (Lithium Iron Phosphate) battery within the B300K, offering ultimate safety, superior stability, and an extended lifespan of over 4,000+ cycles (to 80% of original capacity) or more than 10 years of use, making it a worthwhile long-term investment. This system features an intelligent UPS (Uninterruptible Power Supply) function that automatically switches power sources within just 20 milliseconds during a blackout, keeping your appliances running seamlessly without interruption.

The BLUETTI AC500 + B300K stands out with its fast charging speeds, supporting a maximum input power of up to 8,000W (when charging via AC and Solar simultaneously), allowing you to rapidly recharge high-capacity batteries. Furthermore, easily control and monitor the entire system status via the touchscreen on the AC500 or through the BLUETTI smartphone app. Whether used as a primary home backup system, a power source for large RVs, or the core of a high-efficiency off-grid home, this AC500 + B300K set represents the pinnacle of dependable power.
