Das Kalibrieren bringt bei mir leider nur sehr kurzzeitig eine Verbesserung.
Schon nach wenigen Tagen ist die Ladestandsanzeige der B230 leider wieder komplett falsch und
an der AC200MAX wird “0%” angezeigt und die B230 geht wieder aus obwohl sie geladen ist.
Auf der AC200MAX ist eine sehr alte BMS Version 1017.03
Bitte geben Sie für meine AC200MAX die neueste BMS Version frei, ist das die BMS 1017.07 oder gibt es bereits eine noch neuere Version ?

this is a english forum, would be great if you can also write your articles in english.
I see that you have the same problem as the mentioned article, which resolve this issue by upgrading to BMS v1017.07. @BLUETTI_CARE Can you push this update to this AC200Max Unit?
Hi @Max2, We apologize for the delayed response due to the holiday.
We have applied to upgrade your BMS, our IT department will push the latest version of firmware to your machine in 24 hours. Please upgrade it tomorrow.
Please disconnect the B230 from the AC200MAX, and do not load any device when upgrading it.
After that, please try to do a complete cycle of discharge and charge to correct the SOC. The problem will be resolved.
Please follow the steps below to recalibrate it:
Please discharge all the power (charge AC & DC appliances with the power station) until the SOC is 0%, turn off the machine, and leave it for 3 hours till it cools down.
Please charge it again, please do not load any device when charging it, and do not interrupt it while in charge.
You can click this link for reference.
Please let us know if it does help.
Thank you to @Selfmadestrom for the detailed answer and guidance, it was very helpful.
The update is installed.
A question about the"recalibrate instruction"
“discharge all the power until the SOC is 0%, turn off the machine”
During discharging the DC and/or AC output musst be activated.
When recharging is startet, the outputs are initially off.
But after some time of recharging, the outputs are automatically reactivated.
How could automatic reactivation of the Output be avoided?
Because this contradicts the instructions, at least temporarily:
