I have an AIO 6kW system, which I charge overnight during the cheap period using Wonder Watt. This looks at the SOC and calculates the charge rate required to "fill up".

Last night the SOC was 40% and WW caclulated a charge rate of 50% (in logs this was set to 3035.

However, at the end of the 3 hour period the SOC as reported by the inverter was only 73%, and the energy graph card reported a total import to battery of 9.5kWh!

Anyone have any ideas why this is so? (I have set WW tonight to charge a max rate so should get to 100%)
