Generator set, Power Box BLUETTI AC500+B300K Home Battery Backup

Generators, Power boxes Bluetti AC500+B300K Home Battery Backup
The ultimate power solution for homes requiring maximum reliability and performance. The AC500 does not have a built-in battery; instead, it serves as the core of the system, acting as an advanced 5,000W Pure Sine Wave inverter and the master charge/discharge controller. Working in tandem with BLUETTI B300K expansion batteries (each with a capacity of 2,764.8Wh), it allows you to build a flexible power system tailored to your needs by connecting up to 6 B300K units for a maximum total capacity of 16,588.8Wh—enough to power essential household appliances for days, or even an entire high-energy-consumption 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.
