In my unit (EU version) i’ve this problem during charging
In the picture the right and left part of graphs are charged with PV , the middle one in by AC. Sometimes i have some high drop even during discharging: recalibrating seems not fix the problem. All the data come from Home Assistant integration.
@BogNik This graph looks like it will rise faster at one or two o’clock in the afternoon. This time is generally the best time for light intensity.

About 50% in about 10 minutes is not possible, is like to have an input of 9000W !!!
I wonder if the problem is in the BMS or somewhere where the percentage is calculated.
@BogNik Can you send me the AC300 firmware version and the B300 BMS version?
I’ll ask for the engineer in charge for you.

Anyway Bluetti EU will recall my B300 unit next week.
@BogNik Thank you for your feedback. Can you also provide the SN code for AC300 pls?
