Everything you need in one

The AC500 and B300S, the scalable power system, will definitely change the way you harness solar energy. It's designed to help you deal with power outages and stay connected with unlimited power wherever you go.

Select power for personalization

Thanks to the modular design, the AC500 accepts 6*B300S or 4*B300 expansion batteries (or a combination of B300 and B300S) for a total capacity of 18,432Wh and 12,288Wh, respectively, meeting your off-grid needs for days!

Luckily, AC300 owners looking for a more powerful inverter don't need to order a new bundle because the 5,000W inverter in the AC500 can satisfy their demand without a doubt.

Strong, wonderful

The built-in inverter provides 5,000W of continuous pure sine wave power and up to 10kW of power for a short time at peak power, ensuring that anything you plug in will work to its full functionality and capabilities effortlessly. It's suitable for all scenarios even when you're camping or barbecuing in the backyard.

Endless solar energy for free

Backed by an efficient MPPT controller, the AC500 allows up to 3,000W of solar input - 40% faster than a standard charging speed, so fully charging an AC500+B300S combo only takes around 1.5 hours*.

*Charging time is calculated under ideal conditions and for reference ONLY. The specific charging time may vary due to ambient temperature and other factors.

Unparalleled recharge experience

The AC500 system is designed to recharge any way you want, such as direct connection to solar panels, cigarette lighter car or more efficiently via a 5,000W charging cable*. What's even more exciting is that the AC500 can support up to 8,000W* amazing input rate, making it fully recharged in 15 hours.

* 50A or mains charging cable required.
* Minimum of two B300S packs and dual charging via solar 3,000W and AC 5,000W required. Or the input rate would be limited to 4,500 W with only one B300.

Safe, Smart and Seamless UPS Backup

Whenever the grid goes down, the AC500 system will automatically become your home's power source to keep all necessary loads running without interruption. It also adopts an advanced battery management system (BMS) and LiFePO4 battery to ensure higher operating safety, longer life cycles and optimal performance.

Track and control in the palm of your hand

The intuitive BLUETTI app and touch screen lets you get everything under control, including I/O, real-time power consumption, charging profiles, OTA firmware update and more.

Never run out of energy

The AC500 powers your devices like a gas generator, but without the fuel costs, noise and pollution, making it safe enough to use by your side whether you're at home, setting up a tent or attempting a road trip in a recreational vehicle.

Expandable Battery Pack

The B300S has a capacity of 3,072 Wh and lasts 3,500+ cycles at 80% of its original capacity. Connect 6 packs of B300S to the AC500 and you've got a massive 18,432Wh powerhouse, enough to power your RV, off-grid life and deal with a serious power outage.

Responds even to the cold

Waking up electronic devices on a freezing day can be time-consuming. But with self-heating function, B300S will automatically warm up the battery to ensure it can work actively and smoothly as usual.

Note: The self-heating function does not it will activate if the ambient temperature is below -20C.

Autonomous energy source

More than just an extension battery pack, the B300S can be used as a standalone power source as it features versatile outputs - 100W USB-C, 12V/10A car cigarette lighter and 18W USB-A to power smartphones, laptops, your fans, lights, refrigerators and more.

Amazing fast recharge

Faster is always better. Charge your B300S in 4 hours* at a maximum input rate of 1,000W with 1,000W solar input* or a 500W adapter with 500W solar input.

* Data is for reference only.
* D050S DC charging amplifier is required.

Flexible recharge

BLUETTI B300S needs up to 500W AC, solar charging or car charging.
