Firmware update AC70

I have a pair of AC70s bought about a month ago. One seems to consistently alarm, although I have a hard time figuring out what its problem is. It also says there’s a firmware update available, but I have no idea how to do that.

I was under the impression that Bluettis would prioritize solar over grid, but apparently that’s not possible with this model. In the meantime, I disconnect the grid during the day to run on solar, then turn it back on at night. Is that the issue?

Hi @AllergicToPolitics

You can update the firmware of AC70 by connect it by bluetooth through the Bluetti App. In the top right corner should be a gear to open the settings.

Do you have any error codes?

Thanks, updates done for both.

The error code is E073

Hi @AllergicToPolitics, We have resolved This known issue through the latest ARM firmware update.

Thank you, @Selfmadestrom, for your assistance and guidance.
Yes, please bind your AC70P and update the ARM firmware.
We’d like to know if the issue has been resolved.

Seems fine since the updates yesterday. The sun is (finally) out today, and both seem to be charging back up to full without issues.
