BLUETTI AC300+B300 | Home Battery Backup

FAQS

• Q1: How many B300 expansion batteries can I connect with AC300?

  A:

  A single AC300 can take up to 4 B300 batteries for a capacity of 12,288Wh. Friendly Note: Only B300 can be connected to AC300. B230 can not be connected to AC300.

• Q2: Does AC300 work with third-party expansion battery?

  A:

  No. AC300 ONLY accepts BLUETTI B300 expansion battery.

• Q3: Can I use AC300 alone?

  A:

  No. There's no battery inside AC300 and it must work with B300.

• 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 Smart Home Panel*. Then connect AC300 to the Smart Home Panel.
  * Sold separately.

• Q7: What is the UPS switching time?

  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

  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 use my solar roof to charge the AC300 system?

  Yes, but please note your solar roof should have:
  1. NO micro-inverter
  2. an open-circuit voltage of 12-150V
  3. Include MC4 connectors. However, when the OCV falls in 150-550V, you should use BLUETTI D300S* to step down the voltage and achieve solar charging.
  
  * Sold separately.

• Q10: Can I connect two AC300 systems in series?

  Yes. With BLUETTI P030A fusion box*, you can connect two AC300 systems in series for 240V/6,000W output and a total capacity of 24,576Wh (4*B300 for each AC300).
  
  * Sold separately.

• Q11: Is the AC300 power station waterproof?

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

• Q12: Can it charge and discharge at the same time?

  Yes.

• Q13: How do I know whether my appliance can work well with the AC300 and B300 combo?

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

• Q14: How long can it run my device?

  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.

• Q15: What is the maximum input charging power of the BLUETTI AC300?

  For AC300 with one B300: 3,000W Max. Via a 120V30A wall socket by a 30A 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.

• Q16: Is the AC300 system hot-swappable?

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

• Q17: Is it possible to replace the built-in battery?

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

• Q18: I'd like more tutorial videos on the AC300 system.

  Sure, please follow BLUETTI Support on YouTube..
