## Frequently Asked Questions

**Q: How much battery capacity does the BLUETTI AC300+B300 system provide?**
A: The BLUETTI AC300+B300 includes one B300 battery module with 3,072Wh of capacity. Because the AC300 is 100% modular, you can expand by adding up to four B300 units, reaching a maximum of 12,288Wh of total storage — enough to power a home through multi-day outages.

**Q: What is the solar charging capacity of the BLUETTI AC300?**
A: The BLUETTI AC300 supports up to 2,400W of solar input, which Bluetti describes as "unrivaled." Combined with a total input rate of 5,400W when using multiple sources simultaneously, the system can recharge rapidly from solar panels, the grid, or both at once.

**Q: Can the BLUETTI AC300+B300 power 240V appliances?**
A: Yes. The AC300 supports 240V connection, making it compatible with high-voltage home appliances like dryers, well pumps, and HVAC systems. It also delivers 3,000W of pure sine wave AC output at 100–120V, suitable for sensitive electronics and most household devices.

**Q: Does the BLUETTI AC300+B300 work as a UPS during a power outage?**
A: Yes. The AC300+B300 includes 24/7 UPS (Uninterruptible Power Supply) home backup functionality, meaning it automatically switches to battery power during a grid outage with no interruption to connected devices — ideal for home offices, medical equipment, and refrigerators.

**Q: What charging ports does the BLUETTI B300 battery module include?**
A: The B300 module offers USB-C at 100W, USB-A at 5V/3A, a standard USB-A at 5V/2.4A, DC output at 12V/10A, and a 24V DC power supply port. Note that the DC port is only compatible with DC7909 connectors. AC output runs at 100–120V up to 3,000W through the AC300 unit.

**Q: How many B300 battery modules can be connected to the BLUETTI AC300?**
A: The BLUETTI AC300 is 100% modular and accepts up to four B300 battery modules. Starting with one B300 at 3,072Wh, a fully expanded system reaches 12,288Wh of total capacity, scaling energy storage to match your household needs without replacing the inverter unit.

**Q: What warranty does the BLUETTI AC300+B300 come with?**
A: The BLUETTI AC300+B300 includes a 4-year worry-free warranty. Bluetti also notes that orders ship in multiple packages with separate tracking numbers, so buyers should expect the AC300 unit and B300 battery module to potentially arrive at different times.

**Q: What is the price of the BLUETTI AC300+B300 bundle?**
A: The BLUETTI AC300+B300 bundle is priced at $2,599 USD. Bluetti notes that buyers whose credit cards have limits for large transactions can contact customer service to pay via PayPal or bank transfer. The product is currently listed as out of stock.
