AC200 Max goes to 0% on reboot.

This morning my AC200 was at 16%. It was at 25% when I went to bed last night. I rebooted it and it shows up at 0%! Is there any advice out there? Do I have a defective unit? Is Customer Support my next option?

@Pathwork Please update the BMS firmware to 1017.03 and do a full cycle of charge and discharge to correct the SOC.

I need help with the proceedure. Having never done it, I’m completely in the dark.

Hi @Pathwork , please log in to the Bluetti app, and find the BMS firmware to 1017.03, click upgrade. I have attached a screenshot for reference.

Please do not load any device when upgrading it.
After that, please try to do a complete cycle of charge and discharge 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.
