Battery gone native!

My Gen 1 inverter was replaced by a Gen 2 last Friday. I am also in the process of switching to Octopos and I'm on their standard tariff fir now and they tell me that they are having problems reading my Smart2 meters.
Set up battery to charge "solar +grid" at night from 1:30-4:00am to max of 50%.
But the battery chsrge limit fluctuates above 50%. Last night it got up to 64% and 80% only had a dishwasher on as main load.?? Any diagnosis?

Sorry guys & gals my mistake
It's the graph time range confusing me keeps defaulting to 6 hours. When setting correct date and changing to 1 hour graph makes sense and lines up with my expectations
My excuse half asleep!
