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).

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.

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.

Is there a UPS function when using fusion box?

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

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

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.

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.

Is AC500 waterproof?

No, please keep it in a dry place.

Bluett AC500 w/ B300S battery

Functions as it should. Battery charges well, in a reasonable time. Future plan on using the ability to hook 220 up. Costumer service was very helpful and polite. Shipped fast and without issue.
