Q11: What safety features does the Balco Transfer Hub have?

The unit includes protection against overcurrent, short circuits, overvoltage, and undervoltage. It also contains a 15A fuse, which must be replaced by a qualified professional if necessary.

Q12: Can I check the status of a connected BLUETTI portable power station on the Balco Transfer Hub?

Yes. The unit’s indicators display the device status (see Section 3.3). After pairing the system in the BLUETTI app, you can monitor battery level, charging/discharging status, and other system information in real time.

Q13: When connected via BLUETTI Space, can Balco Transfer Hub pair with other Balco Series products such as Balco 260?

Yes. Balco Transfer Hub can be paired with other Balco Series products, including Balco 260, through BLUETTI Space.

Q14: What are the conversion efficiency and energy loss?

The Balco Transfer Hub achieves up to 94.2% conversion efficiency when feeding power from a portable power station to the grid, with approximately 5.8% energy loss during power conversion.The overall system efficiency depends on the conversion efficiency of the connected portable power station.

Q15: Does the Balco Transfer Hub support three-phase systems?

Yes. With BLUETTI Space, you can install and manage multiple Balco Transfer Hubs in your three-phase home system (smart meter required). However, the total output power remains limited to 800W across all three phases.

Q16: How are multiple devices managed within a BLUETTI Space system?

When multiple devices are connected within a BLUETTI Space system, the first connected unit becomes the “Master” unit, while additional units function as “Slave” units.The Master unit centrally manages and communicates with all Slave units, allowing users to monitor and control the entire system through a single interface instead of managing multiple devices individually.

Q17: How do I enable AI Mode, and what does it do?

Connect a compatible smart meter to enable AI Mode.In this mode, the system automatically optimizes energy use by predicting solar generation, household demand, and electricity prices. It adjusts charging and discharging in real time to improve efficiency, reduce energy costs, and maintain a reliable power supply—without manual setup.

Q18: Why should I use a smart meter?

A compatible smart meter provides real-time insight into your home's electricity use. This helps maximize solar self-consumption and reduce unnecessary grid import and export.

Q19: Can I use the Balco Transfer Hub without a smart meter?

Yes. You can use a BLUETTI S1 smart plug instead, but it can only monitor devices connected to it.Without a compatible smart meter or S1 smart plug, Self-consumption Mode and AI Mode are unavailable. The system also cannot optimize energy use based on real-time household demand.

Q20: Can I use the Balco system during a power outage?

No. During a power outage, the hub automatically stops feeding power to the grid to comply with anti-islanding safety requirements.However, your portable power station can still provide backup power to your devices connected directly to its AC outlets.

Real Stories from BLUETTI Users

See how users turn BLUETTI power stations into flexible energy systems for home savings, outdoor power, and backup.

When turned on, there is a small impulse at the AC charge input that wakes up the station, and then the Bluetooth connection between the 2 devices does the rest.

Jean-Paul Zimille-tran

By installing a smart meter on your main fuse box, the Balco Transfer will monitor consumption in real time and transfer energy from your power station to feed into the grid to cover your consumption

Jean-Paul Zimille-tran

This is a real breakthrough based on a simple idea: using a portable power station to offset the whole home’s baseload consumption and get the most value from the investment.
