  4. 8,000W max. with 2*B300S or more (PV+AC)

• Q7: Can I use other brands' batteries?

  No, AC500 is compatible with B300S or B300 ONLY.

• Q8: What is the power consumption of AC500 when it's off/on?

  1. 11W when AC500 is on, DC and AC are off;
  2. 30W when AC and DC are on.

• Q9: Do I need an extra cable to connect B300 and AC500?

  Yes, P150D to P090D is required, you may order it separately in BLUETTI Store.

• Q10: What is the difference between B300S and B300?

  1) Current capacity: 130A for B300S while 75A for B300.
  2) ONLY B300S features the automatic heating function.
  3) Solar input: 500W for B300S while 200W for B300.

• Q11: How does the heating function work?

  When the temperature is below 0℃, the battery will be automatically heated once AC or PV charging is activated (input power＞400W).

• Q12: Is AC500 compatible with AC300's fusion box?

  Yes.

• Q13: How to connect AC500 to the main panel?

  Low Voltage Area: Match the transfer switch and smart home panel to the main panel.
  High Voltage Area: Match the transfer switch to the main power box.

• Q14: Can fusion box connect with AC500 and AC300 simultaneously?

  Not recommended.

• Q15: What is the maximum power of AC500 when using the fusion box?

  1) 7,200W when connected with P030A
  2) 10,000W when directly connected to the distribution box.
  Note: The split phase function is only available for US Version.

• Q16: Is there a UPS function when using fusion box?

  No, but we do have EPS (emergency power supply).

• Q17: What is the switching time of the UPS?

  20ms.

• Q18: Can I use third party solar panels to charge AC500?

  Yes, the solar panels must meet the following conditions:
  1) Total voltage:12-150V
  2) Total power: 3000W max.
  3) With MC4 connectors

• Q19: Can I use rooftop solar panel to charge AC500?

  Yes, but please note that your solar roof must meet:
  1. No micro-inverter
  2. Open circuit voltage 12-150V
  3. With MC4 connectors
  Note: When OCV exceeds 150V, you may use BLUETTI D300S* to step down the voltage to achieve solar charging.

• Q20: Does AC500 support charging and discharging at the same time?

  Yes.

• Q21：How long will AC500 run my device?

  Running time = battery capacity x DoD x η ÷ device rated power DoD: Depth of Discharge, η: local inverter efficiency. For AC500, both DoD and η are 90%. If you run a 1,000W microwave oven with a AC500 + B300S combo, the running time will be 3,072Wh × 90% × 90% ÷ 1,000W ≈ 2.5 hours
  Note:
  1) This formula doesn't apply to inductive loads with compressors, such as refrigerators, air conditioners, etc.
  2) The above data is for reference ONLY.

• Q22: Is AC500 waterproof?

  No, please keep it in a dry place.

• Q23: Can I use the fusion box in high voltage areas?

  No.
