    What brand and model of inverter are you using?

This problem does not occur at all once the sun is down. I've never posted before, but have read a lot of useful post and info on this site, so thank you.
    I am not sure exactly why you are experiencing those flickers but there could be a problem with your inverter software and the specific properties of the grid. Sometimes a slight voltage dip or frequency change can cause a grid tie inverter to balk and fail to work momentarily but I am just guessing without more data.

    If your system is a typical hybrid set up, you are not running just off batteries after dark, you still use the grid unless the grid goes down. I have a hybrid system (actually dual, one part is just grid tied, a second part is battery back up and grid tied. I get no loss of AC at any time.
    However I have no idea what is malfunctioning.
