Bluetti AC300+B300K Akku-Pack

Overview of Bluetti AC300

The BLUETTI AC300 + B300K battery pack is a modular power system designed for home backup, off-grid use, and high-demand portable applications. Unlike a traditional portable power station, the AC300 is a head unit without an internal battery, which lets you build the capacity you need by connecting one or more B300K expansion batteries.

For users looking for a flexible solar backup system, this setup combines a 3,000W pure sine wave inverter, LiFePO4 battery storage, and strong charging options. It is well suited to backup power for essential appliances, mobile work, and energy independence in locations where reliable electricity matters.

Why Choose the Bluetti AC300 Inverter System

The Bluetti AC300 inverter system is built for people who want more than a basic portable power station. Its modular design gives you room to grow, so you can start with one battery pack and expand over time as your power needs change.

Because the AC300 has no built-in battery, the system is focused on flexibility. This makes it a practical option for households, RV users, and off-grid property owners who want a scalable off-grid power solution.

Wesentliche Merkmale

• Modular design: Add up to four B300K or B300 expansion batteries for increased storage.
• 3,000W inverter output: Supports a wide range of household and workshop devices.
• High-capacity battery storage: The B300K provides 2,764.8Wh of LiFePO4 energy storage.
• LiFePO4 chemistry: Known for long cycle life and stable performance.
• Solar-ready setup: Supports solar charging for off-grid use and backup preparation.
• App monitoring: Manage key settings and check system status through the BLUETTI app.

What You Can Power

With a 3,000W continuous output and 6,000W surge capacity, this system is designed to handle demanding loads. It can support appliances and tools such as refrigerators, small air conditioners, power tools, lights, laptops, and communication devices, depending on your total load and battery configuration.

For customers in Greece preparing for outages or looking for a solar backup system, this level of output can be useful for both home essentials and semi-professional applications.

Battery and Charging Details

LiFePO4 Battery Technology

The B300K uses Lithium Iron Phosphate (LiFePO4) cells, a chemistry widely valued for safety, durability, and long service life. The product details list more than 3,500 cycles to 80% capacity, which makes it suitable for regular use over time.

Fast Charging Options

The AC300 supports high-speed charging, including AC charging and solar input. The system can accept up to 5,400W max input when AC and solar are combined, helping reduce downtime between uses.

For off-grid power solution planning, this charging flexibility can be especially helpful when you want to recharge quickly from the grid or make the most of available sunlight.

Solar Input and Off-Grid Use

The AC300 includes built-in MPPT solar charging support with up to 2,400W of solar input. That makes it a strong candidate for users who want to build an energy independence strategy around renewable charging.

Whether you are setting up a cabin, workshop, or emergency backup plan, a modular battery pack like this can be paired with solar panels to create a more self-reliant energy system.

Home Backup and UPS Function

With the appropriate home integration setup, the AC300 can function as a backup power source with UPS-style behavior. It is designed to switch to battery power quickly when the grid fails, helping protect sensitive electronics and maintain essential power.

This can be valuable for networking equipment, computers, lighting, and other critical devices that need continuous operation.
