Bluetti Home Battery Backup Systems

A home battery backup system is a high-capacity power station that is capable of running an entire household in an emergency. They typically feature high-powered inverters and expandable storage capacities.

All the three Bluetti power stations are expandable to higher levels of storage capacities through pairing or by attaching them to the brand’s exclusive external battery packs.

In this article, we would like to check all the key features of the three home battery backup systems from Bluetti. Stay tuned for our take on Bluetti AC200 Max Vs AC300 Vs EP500.

Bluetti AC200 Max Solar Power Station

AC200 Max is an expandable variant of Bluetti’s famous AC200P midrange solar power station. Being a modular model, you can expand it up to 8192Wh using the brand’s much-excited expansion battery modules. We would like to have a detailed look at the Bluetti AC200 Max portable power station below.

Like AC200P, AC200 Max basically equips a 2048Wh (51.2V 40Ah) LiFePO4 battery pack. The attachable extra battery packs are available in two options; B230 and B300. They are respectively 2048Wh and 3072Wh LiFePO4 external battery packs. An AC200 Max can support up to two units of any of the extra battery modules.

AC200P Portable Power Station


That said, if the included battery pack is not enough for your requirements, you can expand the system with up to two units of either B230 or B300 battery packs.

As you see, the extra battery modules also feature their own USB and DC outlets to power your devices directly. The brand has also on sale a new 200W solar charger for its heavy power stations.

AC200 Max Specs and Features

AC200 Max is actually the first modular solar power station from Bluetti, a leading player in the portable solar power industry. Thanks to its expandability profile, you are lucky to get a much more reliable power station for your off-grid, emergency, and camping life.

The device has faster solar and AC charging options. For charging it from the solar array, it features a 900W (10-145V) input option, whereas, for AC charging, it features a 500W charging inlet.

Besides solar and AC options, you can also recharge AC200 Max from multiple other sources, including an EV station, a solar roof, wind turbines, a regular gas generator, and 12V/24V lead-acid batteries.

In the meantime, AC200 Max highlights four 2200W AC outlets and one US AC TT-30P port. Coming to the USB options, it sports a pair of 18W USB-A outlets, dual USB-A 5V/3A sockets, and one 100W USB Type-C PD port.

The DC sockets include one regular carport with 12V/10A power, two 12/10A DC 5521 outlets, and one 12V/30A port. A pair of 15W wireless charging pads are other attractions.

Compatible Solar Panel

Bluetti has got a new 200W folding solar charger for AC200 Max and AC300.

Branded as Bluetti PV200 solar panel, it is a four-fold high-efficiency mono solar panel with an output of 200W at a conversion rate of 23.4%. It can offer you much better power in low-light conditions than a poly panel.

Built with the highly durable ETFE material, it can ensure long-lasting solar power. It is also scratch-resistant and waterproof with IP65-rating so that you can use it roughly for various outdoor uses like camping, fishing, and more. Check out the product at the Bluetti website below, where it comes at a price of around $500.


Coming up with an MC4 connector, the solar panel is fine for all solar power stations on the market, including all the models from Bluetti. When it comes to the AC200 Max, you can pair multiple units of the charger to achieve the total solar output the heavy power station requires.

Once folded, it gets into a suitcase form, which you can easily carry anywhere. It has a folded size of 23.4 x 24.8 in and its weight goes 16.1lbs. The kickstand helps you place it anywhere for better exposure to the sunlight.

Compared to the former SP200 solar charger, the new PV200 enjoys a few specialties. It has reportedly got an improved performance under shade. You will only lose solar watts from an area that is exactly under the shade, and not all cells won’t be affected by the shade.

Also, the new panel integrates different solar cells and diodes, but still, it has the same conversion efficiency. It is also slightly heavier than the original as it features a wide area of waterproof coating.


Special Features

Bluetti AC200 Max power station enjoys a host of special features.

Hot swapping is one of the key things. This feature makes you quickly swap a drained expansion battery with a fully charged spare unit without the need to turn off the machine.

Moreover, you can have total control of the power station on the included mobile app. That said, it is quite easy for you to manage the solar power station from anywhere in the world as you will get real-time notifications on your mobile screen.

The included and expandable battery packs are highly safe and long-lasting LiFePO4 units.

Added with an award-winning battery management system, AC200 Max can be a great power backup system you can rely on to power up your life off the grid or in an emergency.

Bluetti B230 Expansion Battery

B230 is one of the expansion battery packs Bluetti has designed for AC200 Max and its original.

Specs-wise, it comes with a 2048Wh built-in battery. If the internal battery of AC200 Max is not enough for your needs, you can hook it up with up to two units of B230s for added storage capacity.

The interesting thing is that B230 is also compatible with the brand’s former models like AC200 and AC200P. Bluetti has the extra battery on sale individually or in bundles with AC200 Max.



B230 is actually a handy and compact battery pack with dual built-in carrying handles. You can take it anywhere on your trips and stack it upon your power stations for easy handling.

The battery module also features its own charging outlets. They are one 18W USB-A Quick Charge 3.0 port, one 100W USB-C 3.0 Power Delivery port, and one 12V/10A cigarette lighter charger. That is how you can power up your small devices directly from it.

Bluetti AC200P/AC200 History

Bluetti launched its much-excited AC200 back in 2020 with a 1700Wh LG EV-Grade battery pack. The product could make a wave on the market with over 12K backers supporting it on Indiegogo.

But the company upgraded it with the 2048Wh LiFePO4 battery pack later and rebranded it as AC200P. That product is certainly one of the market’s best-seller mid-range power stations today.

More recently, the brand unveiled two massive solar power stations, EP500 and EP500 Pro on Kickstarter, which also attracted a lot of backers. Most of the brand’s latest products have been doing quite well. They have been true trendsetters as they come up with stunning features, power, and storage capacities.
