Hi,
I have a system consisting of 3 pieces of Multiplus5000VA. My system doesn't work properly. As in the photo below, AC loads are 9,1kW. And I have PV power 9,6kW at that time. But system still draws 988W from the grid. By the way grid set point 10W. What can I do? What is wrong? I don't know. Can you help me.
