FAQs
FAQs
Q1: How many B300S packs can be connected to AC500?
A1: 6
Q2: How many B300 packs can be connected to AC500?
A2: 4
Q3: Can B300S and B300 be mixed in an AC500 power system?
A3: Yes. 4 packs in total.
Q4: Does B300s support App control?
A4: 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?
A5: No.
Q6: What is the maximum input charging power of the BLUETTI B300s?
A6: 1000W Max. with optional D050S DC Charging Enhancer*
* Sold separately
Q7: Can I use car cigaretter lighter or lead-acid battery to charge B300s?
A7: Yes, BLUETTI D050S DC Charging Enhancer* is required.
* Sold separately
Q8: Can I use third-party solar panels to charge the BLUETTI B300s?
A8: 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?
A9: Yes.
Q10: Can I use or charge B300s in sub-zero temperatures?
A10: 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?
A11: 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?
A12: No. Also, please do NOT store it in a humid environment for a long time.
Q13: Is it possible to replace the built-in battery?
A13: No. If the battery pack is faulty or even dead, please contact BLUETTI Customer Service.
Q14: I'd like more tutorial videos on the AC500 and B300s combo.
A14: Sure, please follow BLUETTI Support on YouTube.
Q15: What is the difference between B300S and B300?
A15: 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.
Q16: How does the heating function work?
A16: When the temperature is below 0℃, the battery will be automatically heated once AC or PV charging is activated (input power>400W).
