while I unfortunately don’t own any Fronius inverter myself to tamper with, I’m trying to implement battery control for it.
There’s the powerflowchannelpakku channel to read what’s going into/out of battery but I want to enforce charging or discharging.
The Fronius Modbus document mentions a register ChaGriSet to allow for charging from the grid or not but I have not seen this in the binding.
By chance, has anyone played with or implemented battery control on a Fronius inverter or knows how that would work ? maybe @JimT ? (sorry for pinging you).
