AFCI/GFCI nuisance tripping

We've recently had several customers report that their AFCI or GFCI breakers are tripping. The timing almost immediately after the solar was turned on. We use SolarEdge and Enphase micro's exclusively and both are causing the problem. In one house they have Homeline both 2 pole and single and every day at sunset the only three 2 pole breakers will trip, not one of the single pole. AFCI's were replaced with brand new breakers but that didn't solve anything. Enphase has in line noise filters that we have yet to try. Anyone else have this problem??
