EP500 / EP500Pro / AC300 / AC500 Fusion Box

BLUETTI Fusion Box | Split-Phase Combiner for EP500 / EP500Pro / AC300 / AC500

Two power stations, one bigger output. The BLUETTI Fusion Box links two compatible BLUETTI power stations in split-phase mode, doubling your output voltage and combining their power into a single, larger supply. It’s the bridge that lets a matched pair of units work together for higher-demand loads, whole-circuit backup, and 240V appliances.

How it works

The Fusion Box connects two identical BLUETTI power stations and runs them in split-phase configuration. In this mode the output voltage doubles, and the combined output power scales up based on which units you pair giving you more capability than a single station can deliver on its own.

Combined output by model

• AC300 / EP500Pro: In split-phase mode, output voltage doubles for a maximum combined output power of 6,000W
• AC500: Like the AC300, output voltage doubles in split-phase mode, for a maximum combined output power of 7,200W
• EP500 (Model: P020A): In split-phase configuration, maximum combined output power is 4,000W

Why you’ll love it

Doubled output voltage
Split-phase operation doubles your output voltage, enabling support for 240V appliances that a single unit can’t run alone.

Combines two units into one supply
Pair two matching BLUETTI power stations to pool their output into a single, higher-capacity system.

Built for bigger loads and backup
Higher combined output makes it suitable for whole-circuit backup and more demanding household or worksite loads.

Model-matched compatibility
Designed to work with the EP500, EP500Pro, AC300, and AC500 pairing two of the same model for the rated combined output.
