Thanks Jaco,

The Systems certainly keeps the lights on and make 38KW/h on a good day,  but I have a shading problem on the one string in the winter, which was a design compromise when I designed the house, but watch this space, I am busy  cooking up a new plan.

l like your set up l am trying to do the same ac coupled system with two 10kva Quattros and 4 Eltek inverters. 4.4kw. I have not yet set up the frequency shifting. l would like to know the settings that you applied and also do you have the installer's password?

beautiful set up.
