@Matt drummond bell

You set the grid charger voltages internally in the inverter lower. Since that is the settings used for AC PV charging.

Or in DVCC you can cap battery voltage. But that is global if you have DC mppts it affects that too.

Hhmm ok so absorption v in inverter is not controlling? I am running Daly BMs s on battery aggregator and dvcc is running through that, kind of but not very well it stops all charge when it’s on .
