Everything You Want, All in One

AC500 & B300S, the expandable power system, will definitely shift the way you harness the solar energy. It's designed to help you go through power outages and stay connected to unlimited energy wherever you are heading.

Power Option for Personalization

Thanks to the modular design, AC500 welcomes up to 6×B300S or 4× B300 (or a combination of B300 and B300S) expansion batteries for an overall capacity of 18.432Wh and 12.288Wh, respectively, covering your off-grid power needs for DAYS!

Luckily, AC300 owners who are looking for a more powerful inverter don't have to order a new bundle because the 5.000W inverter within AC500 can fulfill their demand without a doubt.

Powerful, Wonderful

The built-in inverter delivers 5.000W continuous pure sine wave output and takes up to 10kW surge for a short time at peak power, ensuring anything you plug in will run to its full functionality and potential effortlessly. It is suitable for all scenarios even when camping or having a barbecue in the yard.

Endless Solar Energy for Free

Supported by an efficient MPPT controller, AC500 allows up to 3.000W solar input - 40% faster than a standard charging speed, so fully charging an AC500+B300S combo only takes about 1,5hrs*.

*The 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 Recharging Experience

AC500 system is designed to recharge in any way you like, such as directly connecting to the solar panels, car cigarette lighter, or more efficiently via a 5.000W charging cable*. What's even more exciting is that the AC500 can support up to 8.000W* whopping input rate, making it fully recharge in 15hrs.

* Require a 50A charging cable or tie to the grid.
* Require at least two B300S packs and dual charge via 3.000W solar and 5.000W AC. Or the input rate would be limited to 4.500W with only one B300.

Safe, Smart, And Seamless UPS Backup

Whenever the grid goes down, the AC500 system will automatically become your home energy source to keep all your essential loads running without interruption. It also adopts an advanced Battery Management System (BMS) and LiFePO4 battery to ensure higher security during operation, longer life cycles, and optimal performance.

Monitor & ControlIn The Palm of Your Hand

The intuitive BLUETTI App and touchscreen allows you to take everything under control, including power in/out, real-time power consumption, charging profiles, OTA firmware update, and more.

Never Run Out of Power

AC500 powers your devices like a gas generator, but without any fuel costs, noise, and pollution,
making it safe enough to use next to you whether you're at home, pitching a tent, or trying an RV road trip.

Customer Reviews

Based on 3 reviews

AC300 wasn't powerful enough to supply our laundry room, so AC500 brought a nice addition to our autonomous laundry room (2-2.4kW) & water boiler (3kW). We can operate the washing machine AND the drier (or boiler) at the same time, without overloading the unit. Our boiler starts at 3.3kW so it would overload AC300. We also enjoy the extra solar input of this unit.
Careful, it's a bit heavier than AC300. We love both units, but benefit most from this one.

Only downside is the lack of support for B300.
Actually, there is support via a P150D to 90D wire, but it's expensive, and every time we connect a B300 to the AC500 using that wire (direct connection, or via another B300S), we get a beeping sound and a "BMS error" message, which doesn't prevent using the battery. We just need to turn it on manually every morning.

happy with the purchase
