Welcome to our overview of the BLUETTI AC500, one of BLUETTI’s most popular home backup solutions, designed to offer both emergency support and daily power independence.
Here, we will walk you through the AC500’s specifications, features, and purchase options, alongside a detailed examination of user experiences and a look at some potential alternatives. Whether you’re wanting to prepare for extended power outages or if you’re just keen to lessen your reliance on the grid, our guide will provide the insights needed for you to assess whether the AC500 aligns with your home energy needs.
A complete home backup system provides a dependable way to keep your house operational during electricity outages and grid disruptions. Such systems play a vital role in keeping critical appliances like fridges, AC units, and heaters running, reducing interruptions to everyday activities. They are particularly beneficial in regions susceptible to extreme weather or where power stability is an issue.
No, the AC500 only works when it is paired with at least one B300 or B300S battery unit. These battery units and product bundle options are discussed at depth in this article.
The term “rated power” refers to the maximum continuous power output a device like a solar generator or an inverter can produce over an extended period of time, without overheating or experiencing degradation. Essentially, it’s the device’s ability to deliver a steady stream of power under normal conditions. This is different from “peak power” or “surge capacity,” which is the maximum power the device can produce in a short burst, usually to start up appliances with high initial power demands, such as refrigerators or air conditioners.
“Output”, on the other hand, is a broader term that can refer to the actual power being produced and delivered by a device at any given moment. For example, a solar generator with a rated power of 5,000W can continuously supply up to 5,000 watts of power. However, the actual output might vary depending on what is connected to it and the demands of those appliances. The rated power tells you the device’s capacity for sustained output, while the actual output is what the device is currently delivering.
In addition to the AC500, BLUETTI’s home backup solutions also include the EP800, EP900, B500, EP500 Pro, EP760, AC200P, AC200MAX, AC70, AC180, and AC300.

BLUETTI AC500: Power Capacity and Output
In its base configuration, the BLUETTI AC500 comes paired with either a single B300 or B300S battery pack, giving it a base capacity of 3,072Wh. Note that the AC500 itself has no battery – it is modular and can only work whilst paired with either the B300 or B300S, which both have the same capacity of 3,072Wh. The AC500’s capacity is therefore expandable to up to 18,432Wh when additional battery units are integrated – using up to 6x B300S packs (for up to 18,432Wh capacity), or 4x B300 packs (for up to 12,288Wh).
This flexibility means that you can scale your power storage according to your specific needs, whether it’s for daily use, or as a precaution against extended power outages.
In terms of output, the AC500 delivers a rated power of 5,000W, with the ability to handle surges of up to 10,000W. This powerful output can support a range of household devices and appliances.
The system also features a 240V/10kW ‘split phase bonding’ option – a feature that allows two separate electrical phases to work together, doubling the available power supply for heavy-duty appliances. Essentially, it enables 2x BLUETTI AC500 (with 2x B300S battery modules) to join together and double not only their potential output to 10,000W, but also voltage supply to 240V, making it possible to power 240V appliances. This feature is particularly useful for homes that have larger electrical demands.
BLUETTI AC500: Charging Options
The BLUETTI AC500 has 6 different options for recharging: AC (4500W max with 1x B300S, 5000W max with 2x B300S), generator (5000W max), solar (3000W max), car cigarette lighter, 12V/24V lead-acid battery, and dual-charging of AC + solar when using two or more B300S batteries (8000W max).
In terms of solar input capabilities, the AC500’s high maximum solar input capacity of 3000W allows for efficient and rapid charging, particular when combined with AC for dual-charging. The AC500 is compatible with BLUETTI’s 400W solar panels, among others, supporting a VOC range of 12-150 VDC at 15A, which ensures flexibility in your solar array configurations.
(Note: VOC stands for ‘open-circuit voltage’ – the maximum voltage that a solar panel can produce when not connected to an electrical circuit or system and there is no current flow.)
BLUETTI AC500: Battery Expansion Options
The BLUETTI AC500 allows for significant battery expansion. At its base level, the AC500 must either be paired with a B300 or B300S battery, starting at a capacity of 3,072Wh. (Note that batteries from other brands are NOT compatible with the AC500 – it must either be paired with B300 or B300S.)
For those requiring more substantial power backup, the AC500’s capacity can be extended up to a maximum of 18,432Wh. This expansion is possible by connecting up to 6x B300S expansion battery packs, each contributing an additional 3,072Wh, or 4x B300 expansion battery packs for a maximum capacity of 12,288Wh.
However, the AC500 also supports a mix of B300 and B300S batteries, allowing for up to 4 packs to be connected in total, offering users the option to tailor their setup.
What are the differences between the B300 and B300S?
- Current capacity: The B300S offers a higher current capacity at 130A, compared to the B300’s 75A.
- Automatic heating: The B300S includes an automatic heating function for cold environments, which means that when temperatures drop below 32°F, it automatically activates heating when connected to AC or PV charging (with input power exceeding 400W). The B300 does not include this feature.
- Solar input: The B300S supports a greater solar input of 500W, while the B300 is limited to 200W.
- Expansion capability: Up to 6x B300S battery packs can be used with the AC500 for an expansion up to 18,432Wh, whilst a maximum of only 4x B300 packs can be used, reaching a total expansion capacity of 12,288Wh.

BLUETTI AC500: Home Appliance Compatibility
The BLUETTI AC500 is compatible with a wide range of home appliances. Its 5kW rated power output (and surge output of 10kW) ensures that it can support energy-intensive household devices. This includes, but is not limited to, central air conditioning units, large refrigerators, and electric ranges. This output is doubled when two AC500 units are connected with its split phase bonding feature.
The AC500 also has 16 varied outlets, designed to accommodate “99%” of household devices, according to BLUETTI. This includes multiple AC outlets of varying amperages, USB ports for smaller devices, a dedicated RV outlet, and a car outlet, among others.
This compatibility extends to emergency situations as well, thanks to its 24/7 UPS (“uninterruptible power supply”) feature, ensuring that critical appliances stay running seamlessly, even in the event of a power outage.
BLUETTI AC500: Design and Installation
Design
As discussed earlier, the BLUETTI AC500 has both an expandable battery system (with B300S and B300 units, which can also be used in combination), as well as 240V split phase bonding for higher power and voltage needs.
It also offers smart app control via WiFi and Bluetooth, which allows users to manage and monitor the AC500 system remotely.
The AC500 weighs 66.2 lbs (30kg) and has dimensions of 20.5 x 12.8 x 14.1 inches (52 x 32.5 x 35.8 cm), making it relatively portable for its capacity, but still a pretty sizable unit. Note that this weight and size is just for the AC500 alone – the B300S and B300 are slightly bigger still. See the table below for a full comparison of the AC500, B300S and B300.
BLUETTI AC500, B300S, B300 comparison
AC500 | B300S | B300 | |
Weight (lbs) | 66.2 | 83.8 | 79.6 |
