By now you must have heard about the Bluetti AC300, and for those who haven't, well, this article is definitely for you. 

The AC300 is Bluetti's first 100% modular solar generator, meaning the unit itself requires attachable battery packs in order to store your solar energy. 

You may be asking yourself why the AC300 is modular and what some of the benefits may be. 

Stick around as we do a deep dive into the technology that powers this mobile energy storage unit.

What is the BLUETTI AC300?

The Bluetti AC300 is a modular solar generator capable of transforming DC into AC electricity. When paired with its expandable battery pack the B300, the AC300 gains the ability to store and control large amounts of solar energy. 

In essence, the AC300 + B300 combo comprises the following technology:

  • LiFePO4 Battery
  • MPPT Charge Controller
  • Pure Sine Wave Inverter 
  • A whole bunch of high tech electronics 

What are the Features of the BLUETTI AC300?

1. 3000W Pure Sine Wave Inverter

Inverters are required in order to transform the stored energy from DC into AC, without this piece of technology, you would not be able to power any of your devices.

Inverters are rated in watts, this indicates how many appliances can be powered. The higher the wattage, the more appliances that can be powered at once.  

The AC300 is capable and safe enough to take care of your high-power devices like air conditioners, fridges, mowers, and laser cutting machines as it is rated at 3000 watts.

2. Expandable Power Supply

Unique to the AC300, the machine is modular, and requires expansion batteries in order to store energy. 

Why is this beneficial? 

Well, it allows you to create a huge energy storing device by adding multiple battery packs dependent on your storage needs.

If this device was not modular it would be almost impossible to transport. Now you can do so with ease by transporting separate units.

3. 5400W Fast Charging

A solar generator would not be a solar generator without the ability to charge via solar energy.

Simply plug in the adapter and solar panels, and top up your BLUETTI AC300 with an astonishing 5400W input rate.

4. 5 Ways to Charge

The AC300 can charge via 5 methods: 

  1. Wall outlet
  2. Solar panels
  3. Car
  4. Gas generator 
  5. Lead-acid battery

5. 24/7 UPS Home Backup

Using the Bluetti Smart Home Panel, you can tie the AC300 power system to your home grid.

This way if you ever experience a blackout, your solar generator will automatically kick on and supply you with the electricity you need. 

6. 240V Connection Available

With the Bluetti Fusion Box Pro, there is the possibility to pair 2×AC300 units and hook up 8×B300 batteries. 

This means an astonishing battery capacity of 24,576 Wh or 24 kWh!

7. Multiple Outlets for Every Need

What Are BLUETTI AC300 Specs?

AC300 vs AC200MAX: What's the Difference?

The first and foremost way to identify the difference between the two machines is simple.

  • BLUETTI AC300: A modular solar generator that does not work independently of its dedicated battery packs. 
bluetti ac200max solar generator
  • BLUETTI AC200MAX: This is a dedicated solar generator, meaning the device is capable of storing energy without the help of external battery packs. 

Which solar generator is right for you? 

This all comes down to the required application. In a nutshell, if you are an RVer looking for mobile energy storage and use, then AC200 Max should meet all your requirements. 

If you are looking for a UPS to power your home’s appliances when the power cuts, then the AC300 with its expandable battery packs is certainly for you. 

However, it is important to note that the AC300 could be used for both applications. If you require less power for a more mobile application, then detaching some of the battery packs makes this possible.
