• Q10: Can I charge or discharge AC200L in sub-zero temperatures?

  A:

  You can charge the AC200L to power your devices in cold weather, but avoid recharging it below freezing. The temperature ranges for AC200L are:
  Charge: 0-40℃ (32-104℉);
  Discharge: -20-40℃ (-4-104℉);

• Q11: What appliances can AC200L work well with?

  Add up the total wattage of your devices and ensure it doesn't exceed AC200L’s rated 2,400W.

• Q12: How long can it run my device?

  Running time = Battery capacity × DoD × η ÷ Device rated power
  DoD refers to Depth of Discharge and η is local inverter efficiency. For AC200L, DoD and η are 95% and 93%. If you run a 1,000W microwave oven with it, the running time will be:
  2,048Wh × 95% × 93% ÷ 1,000W ≈ 1.81hrs
  Note:
  1) The formula is NOT suitable for inductive loads with compressors, like refrigerator, air conditioner, etc.
  2) The above data is for reference ONLY.

• Q13: What is the maximum input of the BLUETTI AC200L?

  2,400W via AC outlet and solar panels simultaneously.
