For the problem/bug? I’ve created with AI a flow in node-red to limit the inverter’s output when it goes over the 26A and scales back up to 27A when it goes below 26A. Maybe usefull for someone with the same problem in the future.
PS. all software has latested updates multi RS is @ 1.25 energy meter is at the latest version so is the ekrano GX.
