Bluetti AC300 Inverter

The Bluetti AC300 inverter is a powerful, modular power supply unit for setting up a stationary or mobile emergency power system. The model has a rated power output of 3,000 W, a peak power output of 6,000 W and produces a pure sine wave, making it suitable for powering household appliances, electronics, computers, network equipment, lighting, fridges, tools and other devices within the permissible load limit.

An important feature of this model is that the Bluetti AC300 does not have a built-in battery. It is purely an inverter control unit that works in conjunction with the external Bluetti B300 battery module. The inverter will not function without the B300 battery, so a compatible battery must be taken into account immediately when selecting the system.

The modular architecture is one of the main advantages of the Bluetti AC300. Up to four B300 battery modules, each with a capacity of 3,072 Wh, can be connected to a single inverter. In its maximum configuration, the system can achieve a total capacity of up to 12,288 Wh. This enables solutions for both basic emergency power supply and extended autonomous operation of households, offices or technical equipment.

The inverter delivers a pure sine wave, which is essential for the correct operation of sensitive electronics, power supplies, computer equipment, pumps, fridges, communication systems, boilers and other appliances. Unlike simplified inverters, the pure sine wave is better suited to devices that place high demands on power quality.

The Bluetti AC300 supports the UPS function, meaning it can be used as an emergency power supply for the home. This mode is useful during power cuts when essential devices need to remain operational: routers, computers, lighting, CCTV systems, alarm systems, fridges or other appliances.

There are 6 AC outputs at 230 V available for connecting AC devices. This allows several devices to be powered simultaneously without having to constantly switch cables around. The user must monitor the total load to ensure it does not exceed the inverter’s capacity.

For modern gadgets and mobile electronics, the model features a wide range of ports. It features 2 USB-A ports with up to 15 W, 2 USB-A Quick Charge ports with 18 W and 1 USB Type-C PD port with 100 W. The 100 W USB-C PD port is particularly well suited for charging laptops, tablets, smartphones, portable games consoles and other devices that support fast charging.

In addition to the AC and USB outputs, the inverter features DC outputs: 1×24 V/10 A and 1×12 V/30 A. It also supports wireless charging, offering added convenience for smartphones and compatible accessories. Thanks to these connection options, the Bluetti AC300 can power household appliances, DC devices and mobile electronics simultaneously.

The solar input, with a power rating of up to 2400 W, enables the system to be charged quickly via solar panels. Thanks to the MPPT controller, the inverter utilises solar energy efficiently and optimises the charging process. The B300 battery module, with a capacity of 3072 Wh, is stated to be able to be charged via solar panels in around 1.5 hours under favourable conditions.

The model supports seven charging options: via the mains supply, solar battery, car, generator, lead-acid battery, dual AC, and the combined AC + solar battery mode. This flexibility allows the system to be used in various scenarios: at home, in the countryside, whilst travelling, in an off-grid solar installation, or as a backup in the event of an unstable power supply.

For rapid recharging, dual charging is supported, utilising both solar energy and an AC adapter simultaneously. There is also the option to regulate the charging speed via the mains supply. The system can be charged via a wall socket with a power rating of 1,800 W to 3,000 W, depending on the user’s requirements and the connection conditions.

The Bluetti AC300 is equipped with a BMS control system, which is responsible for monitoring and protecting system operation. It helps to monitor the power supply parameters, the charging and discharging processes, and the condition of the connected battery modules. This is important for the safety, stable operation and longevity of the entire system.

The information display allows you to monitor the inverter’s key operating parameters. Intelligent control is also available via the Bluetti app for iOS and Android. Using the app, you can track the system status, monitor operation, check parameters and control the power supply more conveniently.

The inverter’s housing measures 358 × 520 × 320 mm and weighs 21.6 kg. It is a fairly substantial yet portable unit that can be used as the basis for a home emergency power system or as a portable power station. However, for full operation, a compatible B300 battery must be connected separately.

The Bluetti AC300 inverter is the solution for anyone who needs a scalable power supply system with high output, a pure sine wave, UPS functionality, a solar input of up to 2,400 W and the option to expand capacity up to 12,288 Wh. It is well suited for emergency power supply to homes, operation with solar panels, off-grid systems, office equipment and users who wish to build their own flexible energy system based on Bluetti B300 modules.
