A: No, AC500 is compatible with B300S or B300 ONLY.

Q8: What is the power consumption of AC500 when it's off/on?
A: 11W when AC500 is on, DC and AC are off; 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: Is AC500 compatible with AC300's fusion box?
A: Yes.

Q13: 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.

Q14: Can fusion box connect with AC500 and AC300 simultaneously?
A: Not recommended.

Q15: What is the maximum power of AC500 when using the fusion box?
A: 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?
A: No, but we do have EPS (emergency power supply).

Q17: What is the switching time of the UPS?
A: 20ms.

Q18: 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

Q19: 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.

Q20: Does AC500 support charging and discharging at the same time?
A: Yes.

Q21: 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.

Q22: Is AC500 waterproof?
A: No, please keep it in a dry place.

Q23: Can I use the fusion box in high voltage areas?
A: No.

Q24: Why does a warning come up when using a diesel heating pump with the cigarette lighter port?
A: The pump may require more initial power to start. Use a compatible adapter to start and run the pump with our AC outlets.
