Hello Guys! I have to program logic controler to control SMA on-grid invertor power producing. Here is the issue:
I have to determin in what direction current is flowing. If the current flows from the invertor toward the transfer grid I have to decrease (digitaly) the Invertor power until current reach zero. So I dont ask you for a code, it is my job. What I am asking is, Is there aproach to messure AC direction exept shunt ressistanse. I prefer some inductive sensor. Thank you in advance!
