BLUETTI Hub A1 Parallel Box for Apex 300 Features

Two or Three Apex 300 Units in One System

BLUETTI's Apex 300 manual states that two or three units can be connected in parallel using the Hub A1 parallel box. Two units provide up to 7,680W. Three units provide up to 11,520W.

Capacity Grows With Your Batteries

With 12 B300K batteries, a two-unit system reaches 38,707.2Wh of capacity. With 18 B300K batteries, a three-unit system reaches 58,060.8Wh.

One Unit Starts the Others

Power on one Apex 300 and the others in the system turn on automatically. Settings from one unit sync with all connected units. For the BLUETTI app to control the charging mode, set every unit to Auto.

240V Output in Parallel Mode

The Apex 300's AC output voltage selector is unavailable in parallel mode. The output is set to 240V by default.

Three Parallel Ports and Two Output Outlets

The hub has three covered parallel ports and two covered AC output outlets. BLUETTI lists 30A and 50A output options for the Hub A1.

Real-World Applications

Higher output. Combine units when the total load is more than one Apex 300 can supply. A single Apex 300 is rated for 3,840W maximum.

Longer runtime. Add B300K batteries to each unit to build a larger shared battery bank.

Charging several units together. BLUETTI lists simultaneous charging for all connected units.

Practical Comparison

Hub A1 Parallel Box Versus a Single Apex 300

One Apex 300 stands alone and stays within its own output and capacity limits. Connecting units through the Hub A1 raises the combined output and lets you add more batteries.

Two-Cable Option Versus Three-Cable Option

Each Apex 300 in the system connects to the hub with its own parallel cable. The two-cable option fits a two-unit system. The three-cable option fits three units.

Buyer Guidance

Connecting and Disconnecting

Make sure all Apex 300 units are powered off before you connect them. To disconnect, hold the AC power button on one unit until the AC input and output power show OFF, unplug its parallel cable from the hub, then close the cover of the unused port. Follow the Hub A1 User Manual for full details.

This May Be A Good Fit If

• You already own, or plan to own, two or three Apex 300 units
• You need more than 3,840W of combined output
• You want to share B300K battery capacity across units
