My Multigrid 48/3000/35, Venus GX, BlueSolar Charger and Fronius Primo 3000 works with actual firmware. The problem is: Multigrid should charge the batteries with max 35A but he wouldn`t set the current above around 20A. So energy of the Fronius is feed to the grid. DVCC is set on, current limitation off, Pylontech parameters are 100A (4 batteries UB2000 Plus). See picture below.
What`s the problem?
