Charging AIO , graph/stats not reflecting charge going into battery?

Hi

1st post after having AIO unit installed 3 weeks ago. This doesn’t always happen, but yesterday was the 3rd or 4th time i’ve seen this. From the graph below you can see battery start to charge (dark blue below the line) and the battery temp start to rise from about 8am.
So i assume the inverter is actually charging the battery) However, the battery percent doesn’t change from 77% for 2.5 hours, not until around 10.30, then zooms up to nearly fully charged in 30 minutes.

I suspect a stats issue than a fault, but has anyone else seen anything like this.?

Looks like a state of charge calibration issue.

Speak to GivEnergy and they can run the recalibration. The one issue would be the battery will want to fully discharge so you don’t want to ring them with a full battery.
