Bluetti AC300

Overview of Bluetti AC300

The Bluetti AC300 Inverter is a modular power hub built for users who want flexible energy storage and dependable backup power. Unlike an all-in-one power station, the AC300 does not include an internal battery, so it works with external B300 or B300K battery modules to create a system sized for your needs.

With a 3000W pure sine wave inverter, strong solar input, and support for expansion, it is designed for home backup, off-grid setups, and high-demand equipment. For customers in Greece looking for a scalable solar backup system, the AC300 offers a practical path to custom energy storage.

Why Choose the Bluetti AC300 Inverter Module?

The AC300 is built around modularity. That means you can start with one compatible battery module and expand over time as your power needs grow. This makes it a strong option for users who want more control over capacity than a fixed power station can provide.

• 3000W continuous output with a 6000W surge capacity
• Modular design that pairs with external B300 or B300K battery modules
• Expandable capacity up to 12,288Wh with four B300 battery modules
• 2400W max solar input for off-grid charging
• Fast switchover for home UPS backup applications

How the Modular System Works

The AC300 is the control center of the system, while the battery modules provide the stored energy. Because the unit has no internal battery, it requires at least one compatible battery module to operate. This design gives you more flexibility when building a portable or stationary setup.

Compatible Battery Expansion

The AC300 supports one to four B300 or B300K battery modules. As capacity increases, the system can support longer runtimes for appliances, devices, and backup circuits.

Useful for Many Power Needs

This setup is suitable for users who need a modular solar inverter for home backup, travel, or work sites. It can be used to support essential electronics, appliances, and equipment where reliable power matters.

Power Output and Performance

With 3000W of continuous output, the Bluetti AC300 Inverter can support a wide range of common high-draw devices. The 6000W surge capacity helps with startup loads, which is useful for appliances that need extra power at switch-on.

The pure sine wave output is an important feature for sensitive electronics. It helps deliver cleaner power that is better suited to devices that expect stable electricity.

Solar Charging and Energy Storage

The AC300 supports up to 2400W of solar input, making it a strong fit for solar energy storage and off-grid power solutions. Combined with compatible battery modules, it can recharge efficiently from sunlight when the right solar array is used.

The system also supports a high combined charging rate when AC charging and solar charging are used together, which can help reduce downtime between uses.

Home UPS Backup and Emergency Power

For home users, the AC300 can serve as a backup power source for critical loads during outages. The system is designed to switch over quickly when grid power is lost, helping keep essential devices running.

This makes it a useful option for backup power needs such as Wi-Fi, lighting, communication devices, and selected home electronics.
