A:Connect it to the AC500, pair them with BLUETTI App, and you can control the system at any time from anywhere.

Q5: Can I use B300S alone as a UPS?

A: No.

Q6: What is the maximum input of the BLUETTI B300S?

A: 1,000W (AC + Solar) with optional D050S DC Charging Enhancer*
* D050S Sold separately

Q7: Can I use car cigaretter lighter or lead-acid battery to charge B300S?

A: Yes, BLUETTI D050S DC Charging Enhancer* is required.
* D050S Sold separately

Q8: Can I use third-party solar panels to charge the BLUETTI B300S?

A:Yes, if the solar panels' specs fall in
1) Total Voltage: 12-60V
2) Total Power: 500W Max.
3) Include MC4 connectors.

Q9: Can it charge and discharge at the same time?

A:Yes.

Q10: Can I use or charge B300S in sub-zero temperatures?

A: Temperature ranges for B300S are:
Charge:0℃-40℃ (32℉-104℉);
Discharge: -20℃-40℃ (-4℉-104℉);
Storage: -20℃-40℃ (-4℉-104℉).
Technically, it can power electrical devices under such situations, but please avoid charging it.

Q11: How long can it run my device?

A: Running time = Battery capacity × DoD × η ÷ Device rated power
DoD refers to Depth of Discharge and η is local inverter efficiency.
For B300s, both DoD and η are 90%. If you run a 100W light bulb with it, the running time will be:
3,072Wh × 90% × 90% ÷ 100W ≈ 25hrs
Note: The above data is for reference ONLY.

Q12: Is B300S waterproof?

A: No. Please do NOT store it in a humid environment for a long time.
