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.
