Thanks for your input. The BMS does limit the charging to 90A for my 4 batteries. It is more than sufficient though. So in the morning it does limit the input to the battery. I don't mind that as it keeps everything cooler. I also think it is just a software thing. I'll leave it at that for now.
It is round about 270v pv1 and pv2 is both 8x 585w pannels facing north. It makes good power though. Was just worried something is not right. See pics of graphs for today.
