• Q4: Does AC300 support App Control?

  A:

  Yes. Once connected via WiFi or Bluetooth, the BLUETTI App will enable you to control the AC300+B300 remotely, like switching the working mode and upgrading the firmware.

• Q5: Can I use it as an uninterruptible power supply (UPS)?

  A:

  Yes. It supports four UPS modes:

  1. Standard UPS.

  2. Time Control UPS (Pay less for higher electricity consumption).

  3. PV Priority UPS (Recommended for regions with sufficient solar energy).

  4. Customized UPS.

• Q6: How do I connect this to my home main panel?

  A:

  BLUETTI recommends a competent and trained licensed electrician undertake the task. Connect the wires of critical equipment from your house electric panel to BLUETTI AC300 directly.

• Q7: What is the UPS switching time?

  A:

  There are two types of working conditions of UPS for AC300 system.

  • 1) No delay for online UPS;
  • 2) 20ms from standby UPS.

• Q8: Can I use third-party solar panels to charge the AC300 system?

  A:

  Yes, if the solar panels' specs fall in

  • 1) Total Voltage: 12-150V.
  • 2) Total Power: 2,400W Max. (From the two PV input ports)
  • 3) Include MC4 connectors.

• Q9: Can I connect two AC300 systems in series?

  A:

  No.

• Q10: Is the AC300 power station waterproof?

  A:

  No. Also, please do NOT store it in a humid environment for a long time.

• Q11: Can it charge and discharge at the same time?

  A:

  YES.

• Q12: How do I know whether my appliance can work well with the AC300 and B300 combo?

  A:

  Calculate the total wattage of your devices. AC300 should work if the load doesn't exceed its rated 3,000W.

• Q13: How long can it run my device?

  A:

  Running time = Battery capacity × DoD × η ÷ Device rated power

  DoD refers to Depth of Discharge and η is local inverter efficiency.

  For AC300, both DoD and η are 90%. If you run a 1,000W microwave oven with AC300+B300 combo, the running time will be:

  3,072Wh × 90% × 90% ÷ 1,000W ≈ 2.5hrs

  Note:

  • 1) The formula is NOT suitable for inductive loads with compressors, like refrigerator, air conditioner, etc.
  • 2) The above data is for reference ONLY.

• Q14: What is the maximum input charging power of the BLUETTI AC300?

  A:

  For AC300 with one B300: 3,000W Max. Via a 240V15A wall socket by a 15A AC charging cable (sold seperately).

  For AC300 with more than one B300: 5,400W Max. Via 3,000W wall socket and 2,400W solar panels simultaneously.

• Q15: Is the AC300 system hot-swappable?

  A:

  Yes. You can easily swap battery packs for continuous power use, and the system can hold 4 batteries at once.

• Q16: Is it possible to replace the built-in battery?

  A:

  No. If the battery inside your power station is faulty or even dead, please contact BLUETTI Customer Service.
