Bluetti AC300 – 3,000W Inverter + B300 Battery Module (3,072Wh) – Expandable to 12,288Wh

Bluetti AC300 + B300 Battery – 3,072Wh LiFePO4, 3,000W, Modular Expandable System

The Bluetti AC300 redefines home backup power with its revolutionary modular design — separating the power electronics (inverter, BMS, charge controllers) from the battery modules for maximum flexibility. Paired with the B300 3,072Wh LiFePO4 battery module, it delivers 3,000W of continuous AC power that can scale to 12,288Wh by adding additional B300 modules as your needs grow.

About This Item

• Modular Design – Separate Power Unit from Battery: The AC300 inverter unit connects to B300 battery modules via a proprietary connector, allowing you to purchase additional battery capacity independently of the inverter. Start with one B300 (3,072Wh) and add up to three more for a total of 12,288Wh.
• 3,000W Continuous + 6,000W Peak: The AC300’s 3,000W continuous inverter capacity handles the vast majority of household appliances. The 6,000W peak surge rating accommodates the high startup current of compressors, sump pumps, and power tools.
• 3,072Wh LiFePO4 B300 Battery Module: The included B300 provides 3,072Wh of LiFePO4 energy storage with 3,500+ charge cycles (approximately 10 years of daily charging). LiFePO4 is the safest, most thermally stable lithium chemistry available for home use.
• 2,400W Solar Input – 1.5-Hour Solar Charge: The maximum 2,400W solar input (from multiple panels) achieves a full charge from sunlight in approximately 1.5 hours — among the fastest solar charging rates in its class.
• Dual AC Charging – 3,000W Total: Simultaneously charge via AC and solar for maximum charge speed. The dual 3,000W total charging input can fill the 3,072Wh B300 battery in just over 1 hour from AC alone.
• Bluetti Home Integration: Pair with the Bluetti Home Energy Management System to create a complete whole-home backup with automatic transfer switching. Monitor all circuits, prioritize loads, and manage energy flow from the Bluetti app.
• 16 Output Ports: 4× AC outlets (3,000W), 2× USB-C (100W), 4× USB-A (60W), 2× 12V DC, 1× 12V/30A RV outlet, 1× 24V DC, 1× wireless charging pad. Power everything simultaneously during outages.
