There is an update that has been pushed through to not just myself I have been told by Bluetti for the BMS on my AC200Max.
Mine was one of the first AC200Max units that was released, so I understand that newer models are running different BMS versions that are not pushed to models like mine.
Current version is v1010.07
New version v1010.09
Has anybody installed this?
Any issues?
Thanks.
Hi i also have the AC200MAX got it about 1 year ago. The current BMS version i have is v1017.03. This was sent to me a couple of months ago while i was having some minor issues with the BMS and the additional 2*B300 units discharging out of sync. All is good now. B
@DJR BMS 1010.09 improves the accuracy of SOC display. If the SOC of your AC200MAX works well, you don’t need to upgrade the firmware.
Appreciate the reply.
Can I confirm that BMS 1010.09 is the latest version available to my revision of AC200Max?
I am assuming that BMS 1017.03 is a version not available to my revision of AC200Max?
Thanks.
Could someone from Bluetti please reply to my last post.
Thanks
@DJR Different batches have different firmware versions, BMS 1010.09 and 1017.03 are both the latest version.
