Bluetti AC300+B300 test: that’s life with a 3000W solar power plant for your home…or the end of the world


the access to electricity It is a very topical subject. Whether it is for savings, availability or a possible system collapse, there are those who wish to have a source of electrical energy independent of the traditional system. For what might happen.

In fact, power plants like the Bluetti AC300 that we tested at EuroXliver respond more to a request for a giant inverter for the home (or work), a massive 3000W portable power source go to the most remote place we can think of or, who knows, seek life before the end of civilization as we know it. Either way, we’ve tested one of the most comprehensive solutions on the market and we’re ready for what’s next.

3000 W available to save or take us where we want

A friend is convinced that when the current civilization collapses, the key to survival will be knowing how to grow your own food and, if necessary, having a renewable energy source and above all that it works in any place and in any condition. The orchard already has it, as well as the know-how of a gardener.

The Bluetti AC300 charging station requires the B300 battery modules as it does not have its own built-in battery

For the latter, you can use a power station with a large capacity and also supporting solar charging. It’s just the Central Bluetti AC300the brand’s most ambitious and one of the most comprehensive on the consumer market.

The Bluetti AC300 control unit offers a 3000W continuous and stable power outputwhich, as we will see later, could reach 6000 W in some installations that require an element as an array.

The Bluetti power station is not a gimmick to be used. It is of considerable size, well built and although weighs 21.6 kgits integrated handles allow it to be moved by one person, although this is not recommended.

The 3000 W that the AC300 power station can offer is appreciated by a large number of connectors and ports, including six 220/240 V sockets and two wireless charging zones.

The Bluetti AC300 has a design thought to be able to be placed in a safe and stable way on the various B300 units (upside down) that it needs to function, because, despite its appearance and size, does not have its own built-in battery.

The large size of the Bluetti AC300 power station gives you plenty of space to offer a huge connectivity.

The main one is located opposite the station and consists of six 220/240 V DC connectors (20A) supporting a maximum of 3000W, a 12V output (30A) and a 24V output (10A) not usable simultaneously, as well as a USB charging area consisting of a 100W USB-C connector and two USB-A (18W).

A very geeky touch of this Bluetti AC300 station is the dual 15W wireless charging zone located in the upper area. And all the connectors and sockets are protected by a rubber cover, some of which should improve their closure because they are not very stable.

By the way, the operation of the AC300 power station is completely silent. Literally. The only noise we will appreciate is the beep that warns us that the battery is at its limit and will run out in a few seconds or that the battery has been disconnected.

Modular charging station (or giant inverter)

As we expected, despite its large size and weight, the charging station Bluetti AC300 it does not have its own battery. To use it, it is necessary that we have drum modules that we connect instantly using the two direct connectors located on one side of the station. The kit we tested in EuroXlive includes a B300 unit with 3072Wh capacity.

The maximum scalability of the AC300 stations would allow for a 6,000 W power generation system and an autonomy of more than 12,000 Wh.

An important advantage of this Bluetti kit is that it is a modular system in which we can integrate from a up to four batteries, for a total of more than 12,000 Wh. In addition, and already with a special module from the brand itself, it is possible to combine two of these combinations in a single system to obtain a 6000 W continuous power generation system.

The size and weight (36 kg) of the B300 battery is very considerable

These energy storage modules can be plugged in and unplugged when hot, as discussed below. If we add the fact that they can be charged independently, a station is configured which must never run out of available power.

The Bluetti central can also be connected to the main domestic network via a specific module (about 1,400 euros) with the ultimate aim of acting as a great home inverter. So when the main grid suffers a blackout or blackout, the 3000W power station takes care of keeping the home’s electrical appliances and systems running during the emergency.

A 36 kg Powerbank that you can recharge with solar energy

An interesting point of the Bluetti B300 batteries is that on their own can serve as a source of energy, yes, only to charge specific devices and that support the available connectors. Imagine a Powerbank weighing more than 35 kg and you’ll be right.

Each Bluetti B300 battery module offers a capacity of 3,072 Wh but weighs more than 35 kg

These Bluetti B300 units have their own power button and connectivity consisting of one USB-C port (100 W) and a USB-A (18 W), as well as a 12V/10A connection for cigarette lighter connections.

The maintenance of these Bluetti batteries requires a charge every 3 to 6 months at least depending on the manufacturer. use cells LifePo4 with a life cycle of more than 3500 loads (80%)dropping to 50% capacity from around 6000 charges.

B300 charging connectors

Although as we will see later the B300 batteries gain by being connected to the AC300 station for recharging, they can be independently charged using different sources, sockets to solar panels, although limited to a contribution of 200 W for said solar load. This limitation is removed when we use invoicing
