Got it now, so the situation is like this:
1. Now you also have Max capacity of the main panel, Now how do you calculate available capacity if there are more than 1 charger?
Master charging is doing all the calculations, because master charger is able to see slaves charging data and also NON EV load from Smart meter
Master’s MAX power from grid, is the value that we have for everything EV Load+NON EV.
F.E if you have 100A for everything, to the masters max power from grid we write 100A. And let’s say your building is consuming 75A, Master charger will know that for all the charging stations at that moment we have 100-75=25A and will split it.
To read data from Energy meter in DLM mode “MEASURE GRID LOAD” must be enabled
P.S Reaction time for actions after change of available amps by default is 3 seconds, but could be adjusted at “current update interval”
