  4. 8,000W max. with 2*B300S or more (PV+AC)
• Q7: Can I use other brands' batteries?
  A: No, AC500 is compatible with B300S or B300 ONLY.
• Q8: What is the power consumption of AC500 when it's off/on?
  A:
  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?
  A: Yes, P150D to P090D is required, you may order it separately in BLUETTI Store.
• Q10: What is the difference between B300S and B300?
  A:
  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?
  A: When the temperature is below 0℃, the battery will be automatically heated once AC or PV charging is activated (input power＞400W).
• Q12: How to connect AC500 to the main panel ?
  A:
  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.
• Q13: What is the switching time of the UPS?
  A: 20ms.
• Q14: Can I use third party solar panels to charge AC500?
  A: Yes, the solar panels must meet the following conditions:
  1) Total voltage:12-150V
  2) Total power: 3000W max.
  3) With MC4 connectors
• Q15: Can I use rooftop solar panel to charge AC500?
  A: 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.
• Q16: Does AC500 support charging and discharging at the same time?
  A: Yes.
• Q17: How long will AC500 run my device?
  A: 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.
• Q18 : Is AC500 waterproof?
  A: No, please keep it in a dry place.
• Q19: Can I use the fusion box in high voltage areas?
  A: No.
