This is in a very sunny place, no shade so with 3.5kw, 1kw is very low which I think they may have a few strings of the array are not connected. However why that bothers me is that the VOC/VMP voltages are too close in looking at the CC. Which leads me to think its been told to back off to the 1.0kw, by some setting, see #2. And its always around .8 selling and around 1kw output from the array. <br><br>2. There is a programing issue. <br><br>3.
