Hi @Brett

welcome to the bluetti community forum!

What exactly you mean with “turned off”? That there arent any outputs active and the unit is in standby or when you really turn it off with the power button?

How much charge you loss?

Thanks
Erik

Hi @Brett , I agree with @Selfmadestrom 's opinion.
Please make sure you turn off the AC200MAX completely.
Does it work? Meanwhile, please confirm the BMS version is the latest one. After that, please try to recalibrate the AC200MAX to correct the SOC. The problem will be resolved.
Please follow the steps below:

  1. Please discharge all the power (charge AC & DC appliances with the power station till it is out of power and turns off automatically);
  2. Please charge it again, please do not load any device when charging it, and do not interrupt it while in charge.
  3. Once the power is 100% fully charged, turn off the machine, and leave it the whole day.
    Please let us know if it does help.
    If not, please contact us for further service.
