If the inverter were in search, I would think that there would be no AC
power produced by
the micro inverters at all because of anti-islanding.

Nope wasn't in search when I had flicker.
If the loads were greater than the enphase production then no flicker.
If it was "charging" then there was flicker.
My vfx 3524 is 8+ years old, but I don't think that would be a factor.

Check and confirm that the OB is not set in search, yhis will cause
issues like this.

Subject: [RE-wrenches] AC-coupling Enphase/XW Causes Flickering of
Lights
Hi Matt,
I can’t tell you the reason but I had the same problem on my Outback VFX.
I didn’t put it on a O scope, but sure looked like a 60 cycle flicker
to me.
On my system of 2 enphase, when the loads exceeded the output of the
enphase the flicker when away.
But only 2 isn’t very real world.
In the end it was just a test for me, and it didn’t work.

I wired an Enphase string into my critical loads panel at my shop.
I was curious to see how it would work as I have customers with
Enphase systems that occasionally contact me about adding a battery
backup system.
Why do the fluorescent lights and LEDs flicker once the grid power
is dropped. The flicker seems to start as soon as there is enough
sun to power up a few of the micros (they don't even have to be
making much power).
The shop is grid-tied with a XW 4024 for battery backup. Battery
capacity is 370Ah.
I'd love an explanation as to why this happens and if there is a way
to mitigate the flicker I would also love to hear it.
Many thanks!
