AC180T no charging at low grid voltage

  1. I tried to reinstall it on my phone
  2. It is the latest version
  3. In the message above I wrote that I tried it on a different phone with the same result

Hi @magicpurplecow, that is weird, I have reported it to our engineer.
Can you take a video or some photos to show this problem?
Is there any error code on the Bluetti app? Meanwhile, please tell you your cellphone model and app version.
If you agree, we can also roll back your firmware to the initial version, which might resolve the issue.

New update from 27.08 resolved this issue. It wasn’t working, now it does. The UI also changed a bit. Works on both phones now

And thanks for the firmware update. I’ll definitely be able to check how it works soon.

Hi @magicpurplecow, thank you for letting us know.
I am glad to hear that the problem is resolved.

I’ve been able to test the charging with low voltage once already.
I had 185v or so, it was charging. One test may not be enough, but considering where I live, I’ll test it more than once…
Thanks

I have the regular AC180, do you think this firmware will work with my unit?

I also live in a country with frequent power outages and I have a generator but it outputs 215V. During high load it would go as low as 188V. I use the AC180 as a buffer between the generator and my electronics, however at the most recent outage, I noticed the GRID indicator flashing and the generator voltage was fluctuating between 204V and 188V.

Hi @seesaaaw, I think the new firmware does help, we suggest you try it.
I have applied to upgrade your DSP to our IT department. They will push the latest firmware version to your machine next Monday.
Please upgrade it then.
Please do not load any device when upgrading it.
Please let us know if it works.

Thank you, I have received the update. I will have to wait until the next power outage to test it.

Hi @seesaaaw, Thank you for letting us know.
We hope everything goes smoothly from here!
