I've noticed this is worse with multiple bulbs in one fixture, and it is even slightly noticeable on grid power, but worse on inverter power. I first saw this with CFL's also, but not as bad as with the LED's. And this is without any motor loads going. It's not consistent either, sometimes it does it and sometimes not. Fortunately, when it's annoying we have the option of going onto grid power. If we were on inverter power all the time I'd be looking for some way to fix it also. It does not seem to matter what inverter it is either, I've tried four different brands and they all seem about the same.
