KayJay Yeah, it just looks like based on your input for daily usage, 8kWh and battery capacity of 5.2kWh, given that the solar prediction for your system was around 9kWh, the decision was to charge up to 40% only.
Looks like you tweaked it now to always charge to 100%, in which case you don't need the smart charge, and can change it to a Fixed charge instead.
