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?


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.

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?


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.
