Not sure how many of these are out there in an off-grid setting. But my 45 panel setup was updated to FW ver: 520-00082-r01-v04.40.01 on 09FEB2024 which has completely SOLVED the issue I was having for several years with regard to power factor issues.
My setup is a dual Sol-Ark 12k and 45 Panasonic panels with IQ7x micros. For the past several years I've mitigated flickering and UPS relay clicking whenever the solar production was limited due to clouds or sunrise/sunset. The mitigation was to eliminate one of the four strings (~11 panels) until the production of the remaining units exceeded some threshold. Note: Although the main issue was low production, the issue was also caused by various loads even when in full solar production ie, the clothes dryer could also affect the PF of the micros.
It is hard to describe the relief I feel that the system is finally operating the way it should. It also has the added bonus of more production since I can keep all 45 panels active regardless of power level. I also removed all of my logic necessary to control string connections etc.
Just wanted to post this in case there are others out there who have been struggling with Enphase IQ7x. I had requested assistance on their community forum years ago, with no solution. I'm not sure why it took this long to fix the issue, but better late than never.
