Specifications
Last checked on 11 November 2026. The grey text under each name explains what the value means.
| Specification | Value |
|---|---|
| Storage | |
| CapacityHow much energy the battery stores. Bigger means longer runtime or more of your own solar power used later. | 3,072 Wh per B300 or B300K battery module, and the system takes up to four: 12,288 Wh in total. The AC300 inverter module has no battery of its own |
| Battery chemistryLFP (lithium iron phosphate) cells are known for long life and stable behaviour with heat. | Lithium iron phosphate (LiFePO4) |
| Cycle lifeHow many full charge and discharge cycles the cells are rated for before they hold less than the stated share of their original capacity. | 3,500+ cycles to 80% capacity, 6,000+ cycles to 50% |
| ExpansionExtra battery units that add storage to the same system. | Up to four B300 or B300K modules |
| Output | |
| AC output (continuous)The power it can deliver all the time. Add up the watts of what you want to run at once and stay below this. | 3,000 W in total through six AC outlets, 220-240 V, pure sine wave |
| AC output (surge)A short burst above the continuous rating, for appliances that draw more power when they start. | 6,000 W |
| USB-APorts for phones, tablets and small devices. | 2 ports, 5 V 3 A, plus 2 ports at 18 W |
| USB-CPorts for laptops, phones and tablets. Power delivery up to 100 W can charge most laptops. | 1 port, 100 W maximum |
| Car outletA 12 V socket like the one in a car, for car accessories. | 1 outlet, 24 V 10 A (regulated); also a 12 V 30 A RV outlet |
| Wireless chargingA pad on the unit that charges a compatible phone without a cable. | 2 pads, 15 W maximum each |
| Charging | |
| AC chargingHow fast it charges from a wall socket. Higher means a shorter wait. | 3,000 W maximum; the rate can be adjusted |
| Time to charge from the mainsHow long a full charge takes from a wall socket. | Not stated |
| Solar inputHow much solar panel power it accepts. A higher figure fills the battery faster on a sunny day. | 2,400 W maximum, 12-150 V DC, 12 A |
| Car chargingCharging from a car's 12 V or 24 V socket while driving. Slow, but useful on the road. | 12/24 V through the cigarette lighter port |
| Backup switchover (EPS)What happens when the grid fails. EPS means it takes over automatically. | BLUETTI describes 24/7 UPS home backup but gives no switchover time |
| Pass-through chargingWhether it can power devices while it is itself being charged. | BLUETTI says it can charge and discharge at the same time |
| Housing and warranty | |
| Dimensions (L × W × D)Length, width and depth of the unit, so you can check that it fits the space it needs. | 520 × 320 × 358 mm for the inverter module |
| WeightMatters for lifting, wall mounting and moving it. | 21.6 kg for the inverter module, without batteries |
| Operating temperatureThe range it is rated to work in. Cold and heat can reduce performance. | -20 to 40 °C |
| Protection ratingIP ratings show protection from dust and water. IP55 and IP65 are rated for outdoor-style exposure; check the installation guidance. | Not stated |
| ConnectivityHow you monitor and control it, usually through an app. | Wi-Fi and Bluetooth with app control |
| CertificationsSafety and grid standards the maker says the product meets. | UL2743, UKCA, TELEC, RCM, FCC ID, CE |
| WarrantyThe period the maker covers. Read the terms: conditions and capacity guarantees differ. | 4 years |
How long will it run your devices?

The estimate assumes 85% of the rated capacity is usable after conversion losses. BLUETTI does not state this figure, so we use a cautious assumption. Real running times vary with temperature, battery age and how each device draws power.
Compatible with
What BLUETTI says this product works with. Anything not listed here is not confirmed.
- Batteries
- B300 and B300K, up to four. The AC300 does not work without at least one.

Rules where you live
A portable power station is not wired into your home, so it is simple to use almost anywhere. Connecting one to your home circuits to power the house is different, and the rules for that vary by country. See our country guides for the rules, incentives and prices where you live.

Where this information comes from
We have not tested the AC300. Every figure comes from BLUETTI's AC300 Inverter Module Generator page and its Tech Specs section, last checked on 11 November 2026. Dimensions and weight are for the inverter module alone. A value that BLUETTI does not state is shown as not stated.
We do not show prices, because they change often and differ between sellers.

Common questions about BLUETTI AC300
Does the AC300 come with a battery?
No. BLUETTI sells the AC300 as an inverter module that requires a B300 or B300K battery to work, and it takes up to four.
What can it run?
3,000 W continuous, 6,000 W surge. Divide the battery capacity by a device's draw for a rough running time, for example 3,072 Wh with one B300.
Is the AC300 the same as a home battery?
No. It is a portable, modular power system that you plug devices into. An installed home battery is wired into your electrics by an electrician. See our guide to plug-in and installed home batteries.
