Hi all,

I installed this Fox H3-10.0-E inverter in mid January. Since last three days i have been monitoring my pv production graphs and i can see a sudden fluctuation in the graph where pv production comes to 0 and then after few minutes pv production comes back to normal. Below are the images for last three day. Fox support updated the inverter firmware on 12th March to latest ones. What could be the issue. Also no errors are logged as well a bit confusing for me. And i couldnt see this issue in previous graphs/analytics.

Maybe something interesting for your: The pv volts exactly at that time when this issue is happening are also fluctuating, current going to 0. Moreover the grid volts, frequency is fine but current is 0 at that time: Is it possible it is grid related issue?
