- Why Choose BLUETTI AC500 & B300K?
The BLUETTI AC500 & B300K modular power system is a premium energy solution built for high-demand residential, mobile, and off-grid scenarios. Engineered for flexibility, scalability, and smart energy management, this system combines cutting-edge inverter technology with long-lasting battery storage.
Each AC500 inverter delivers a powerful 5,000W pure sine wave output with 10,000W surge capacity. Paired with the B300K battery module—each providing 3,072Wh—you can configure your setup with 1 or 2 AC500 units and 1 to 12 B300K batteries, enabling a wide range of applications from RV use to whole-home backup.
In single-inverter setups, you can connect up to 6 B300K batteries for 18,432Wh of energy. With dual AC500 units in split-phase mode (enabled via the Fusion Box Pro), your system can handle up to 12 B300K batteries, delivering a massive 36,864Wh of storage. This makes it a powerful choice for heavy-duty off-grid living or uninterrupted emergency backup.
