Have been a very happy user of WW for 12 days now. Thank You very much for this fine service. It does what it says on the box! Looking forward to spring and some more sun:)
I have a request for a feature: A setting for Max battery charge. Preferably alongside the setting for Battery capacity.
As is, WW uses Inverter power (from Growatt) as reference to charge percentage. Not the max charge for the battery.
In my case with a 10 kW inverter and a 12.8 kWh battery, the max charge is around 6.5 kW, which is 50%. So it makes no difference for charge power if WW sets it to 50% or 100%.
The battery management system limits current to around 8 A. So, with a HV battery system, where more power is achieved by stacking more batteries in series, the amperage will stay the same, only voltage (and capacity) vil raise.
A setting for the relevant Max Charge Power will make it possible to charge "Low and slow", also if You have a big inverter and a small battery.
