A Closer Look at the AC300

AC300 is the simple way to build a backup system around your life. It holds no energy by itself —
it partners with Bluetti expansion batteries to deliver strong, steady power to the things that matter.
Start with one battery for essentials, then add more when you want longer runtime.

Going off-grid or camping? Add a PV350 Portable Solar Panel to top up during the day.
Need longer backup at home? Pair AC300 with the B500 Expansion Battery for quiet confidence through longer cuts.

Modular today, future-ready tomorrow — without the complexity.

Does AC300 include a battery?

No. AC300 is the inverter module in a modular backup system. It does not store energy on its own, so you need at least one compatible Bluetti expansion battery before it can operate.

What should I pair it with first?

For most home backup setups, start with a B300 battery. That gives you 3,072Wh of stored energy and a strong foundation for longer runtimes. If you want a different entry point, the B300K is also part of the AC300 battery path. You can add more compatible batteries later as your needs grow.

Can it use solar?

Yes. AC300 supports solar charging and can take up to 2,400W of solar input. A panel such as the PV350 can be part of a portable solar setup, depending on the overall system you want to build.

How much can it power?

AC300 delivers up to 3,000W continuous output with 6,000W surge. That makes it suitable for essentials such as fridges, freezers, routers, lights, laptops, TVs, and many tools, depending on their starting and running wattage.

Is setup difficult?

No. Once connected to a compatible battery, AC300 is designed to be straightforward to use. Connect the battery, plug in your devices, and monitor the system through the Bluetti app.

Will it switch over during a power cut?

AC300 supports backup power with switchover in under 20 milliseconds, helping keep important devices running during outages.

Can I expand later?

Yes. AC300 is designed for modular expansion. You can start with one battery and add more later if you need longer runtime, with support for up to four compatible batteries in total.

What warranty do I get?

You get a 4-year Bluetti manufacturer warranty, plus free UK delivery and 30-day returns from VoltReady.
