Hi Owen,
Looks Like you may have solved my initial question I posted in a different thread, to the issue of not being able to scale back the charge current in DVCC. Do you use node red in HA ? or on the Cerbo it self ?
I have a similar issues as above, my system trips on high voltage or over current to the JK, when the sun comes out from behind clouds, as it jumps from a low solar value to around 15kw very quickly, too quick for the MPII (Multiplus 2) to adjust the frequency and back off the two fronius inverters. I tried adjusting DVCC from HA, i could do it in the victron device in the device, list, but when I ran a script it would just drop it to zero or do nothing at all.
The other issue is similar to above on nice clear sky days, with good solar production I start to get high charge current issues as we get to 90%. I have found if I go into DVCC and scale back the Max charge from 240 to 180 it seems to be enough. So your node red script might be the answer.
My cerbo is doing a lot and I didnt want to overload it with Node red as well, have you seen any issues with this ?
My Cerbo controls data links to 2 x MPPT, 2 x MPII, 2 x Vic EV chargers and 2 x AC coupled Fronius Inverters as well as the 6 JK-BMS, and one Shunt, as well as passes all this data off to Home assistant and VRM.
