Still an excellent solar generator

The Bluetti AC240 in a nutshell

The Bluetti AC240 is the worthy heir to the famous Bluetti AC180. The manufacturer succeeded in eliminating the weak points of its former top-of-the-range solar generator while adding many useful and practical improvements.

The Bluetti AC240 is available from May 20, 2024 and can be purchased via Bluetti’s official website or from the manufacturer’s official Amazon store.

Bluetti currently has an introductory offer, retailing the AC240 for $1,399 instead of $1,899.

Design

The Bluetti AC240 might look imposing, but the design is practical enough to stow the IP65-certified generator in the trunk of a car whenever you travel. If you don’t have enough capacity to use it as intermediate storage for your balcony power plant, you can connect extension batteries to it.

Pros:

• All outlets are covered.
• IP65 certified.
• Cable bag is included.

Cons:

Bluetti remained true to its usual dark colors. To transport the solar generator around, there are two side handles to help you. The fact that the carrying handles don’t protrude outwards, as on the EcoFlow Delta 2 Max (review), is a positive point. Apart from that, the Bluetti AC240 has a high-quality finish, just like how all other Bluetti power generators are built.

In front, there is a small display and ten sockets to choose from:

• 4x 230 V sockets
• 2x USB-C ports
• 2x USB-A ports
• 1x 12V cigarette lighter
• 12V/30A socket for your camper van or boat

The fact that Bluetti offers protection of all sockets from dirt with rubber covers makes the electrical generator, despite its dimensions of 41.9 × 29.4 × 40.9 cm, a good option for camping.

What’s more, the AC240 is protected against water and dust with its IP65 certification. Bluetti also equipped it with rubber feet, ensuring the unit won’t slip or slide when you’re out on your boat. The bag that comes with the generator is also very practical.

On the right of the generator is the connector to hook it up to an additional battery. Thanks to the AC240’s modular design, stacking Bluetti-B210 extension batteries is not a problem at all. On the left, you’ll find sockets to charge the AC240 with electricity. There’s also a grounding socket on this side.

Application and features

The Bluetti AC240 features a bright display so you can keep an eye on it at all times. The Bluetti app keeps you informed, even when you’re on the move. The advantage of the app is how it allows you to temporarily increase the generator’s power.

Pros:

• Clear and fuss-free application.
• Legible display.
• Numerous practical, connected functions.

Cons:

There are two ways to control the Bluetti AC240. The first option is via the button layout on the generator in combination with the very legible display, while the other is via the Bluetti app. Adding the AC240 will take a minute. All you need to do is connect to a wireless network and Bluetooth.

After setting it up, you’ll see the same information in the application’s main menu as on the screen. In addition to input and output power, you’ll always know the remaining battery life. It’s also useful to know how much longer the generator will be able to power connected devices.

The advantage of the app is the diversity of its functions. In principle, you can control the AC240 as you would with the button layout. However, only the app lets you activate Power Lifting mode. This allows the generator to briefly increase output power up to 3600 W.

Bear in mind such power is only available for a fraction of a second. Alternatively, you can set the charging mode of the Bluetti solar generator in the app with three levels to choose from. The slower the level, the longer you can preserve the AC240’s battery.

Battery and charging

The Bluetti AC240 powers appliances with 2400 W and can even hit 3600 W for brief periods of time. It also features a pass-through charging function and can be used as an inverter.

Pros:

• 2400 W output power, capable of rising to 3600 W for a short time.
• Expandable to 10 kWh.
• Reliable UPS function.

Cons:

The Bluetti AC240 left us with an excellent impression in the review. The Chinese manufacturer advertised a nominal capacity of 1536 Wh. In reality, the AC240 consumes 1655 Wh at full charge. You can use 1262 Wh of the energy expended at full load.

This “wasted” power doesn’t just disappear into thin air: the generator dissipates it in the form of heat via the fans. The AC240’s 76% efficiency isn’t the highest on the market, but it’s right smack in the middle, and an improvement over the Bluetti AC180.

With the help of B210 extensions, you can increase the generator’s capacity by up to 10 kWh. Another advantage of the AC240 is that it can be powered by up to 1200 W of solar energy.

To put it plainly: you could connect the best folding solar panel on the market today, the Bluetti PV200 (review), to the AC240 six times and still not exploit its full potential. A cable with an MC4 connector for your solar panels is supplied with the AC240.

When it comes to power output, Bluetti’s electric generator doesn’t do too badly. In principle, it delivers up to 2400 W continuously, and can even go up to 3600 W briefly.

Wireless charging is not possible with this electric generator. However, the AC240 has a pass-through charging function. It also has a UPS function for backup power. This means that the AC240 can function s an inverter when it’s plugged in between the device and the mains and you’re out of power.

Bluetti’s generator contains a LiFePO4 battery designed for 3,500 cycles. A quick-recharge function is also available. When connected to the domestic electrical grid, the AC240 charges with a power of 2200 W and reaches 80% after 45 min thanks to the fast recharge function.
