BLUETTI AC300 Inverter Module – Works with B300K Expansion Batteries
- Modular 3,000W pure sine wave inverter module for creating a scalable portable or home-backup power system.
- Requires at least one compatible BLUETTI B300 or B300K expansion battery; the AC300 has no internal battery.
- Use up to four compatible battery modules, providing 2,764.8Wh to 12,288Wh depending on the selected battery configuration.
BLUETTI AC300
The BLUETTI AC300 is a modular inverter and power-management unit designed to work with B300 or B300K LiFePO₄ expansion batteries. Add at least one battery to create a usable energy-storage system, then expand to up to four compatible battery modules as energy requirements grow.
The AC300 provides 230V AC, 12V DC, USB and wireless-charging outputs, with mains, solar, vehicle, generator and lead-acid battery charging options. It is suited to backup power, campervans, mobile work, camping and portable energy storage where a modular battery arrangement is preferred.
Key features
- 3,000W continuous 230V AC output with 6,000W surge capability.
- Compatible with B300 3,072Wh and B300K 2,764.8Wh expansion batteries.
- Connect up to four B300 or B300K batteries using P090A battery cables.
- Dual MPPT solar input, accepting up to 2 × 1,200W solar charging input.
- Six AC outlets, 100W USB-C PD, USB-A, 12V/30A DC output and two 15W wireless charging pads.
Where to use
- Modular home backup for selected circuits and essential appliances.
- Campervans, caravans, mobile workspaces and temporary accommodation.
- Solar-powered energy storage for remote work, events and outdoor operations.
- Portable power for communications, IT equipment, lighting, refrigeration and compatible appliances.
For example, an AC300 paired with one B300K provides a 2,764.8Wh system, while four B300K batteries provide up to 11,059.2Wh. Do not use the AC300 without a connected compatible battery.
