It is not functional by itself, only with a separate battery pack.

The BLUETTI AC300 is a professional, modular network inverter, specially designed as a backup energy source at home or for more serious off-grid systems.

Modular construction (No internal battery!)
Its most important feature is that the AC300 does not contain an internal battery. It is a control unit and inverter to which B300 battery modules must be connected. A single AC300 can handle up to 4 B300s, so its capacity can be expanded from 3,072 Wh up to 12,288 Wh.

Brutal performance
- 3000W pure sine wave inverter: Safely starts and operates almost any household appliance (refrigerator, air conditioner, coffee maker, power tools).
- 6000W peak power: It can withstand devices requiring extreme starting current for a short time.

Lightning fast charging
The system supports combined charging: if you plug it into the wall socket and connect the solar panels at the same time, you can charge with an input power of up to 5400W, which drastically shortens the waiting time.

UPS (Uninterruptible Power Supply) function
In the event of a power outage, the AC300 takes over in less than 20 milliseconds, so computers or medical devices (e.g. CPAP machines) continue to operate without interruption.

Smart control
With the built-in Bluetti application, you can also monitor consumption, charge level and update the machine's software from a mobile phone via Wi-Fi or Bluetooth.
