Hi Jay
I have not had experience with the sunny boy island. but I have had with the Outback.
In my case I would go with outback. The capability of the FNDC would make my decision. I have done a five inverter stand alone 6 yr ago (maybe seven), and it is still working fine. Same batteries. I also have a 12 inverter grid tied, so far not a problem. The five inverter is a quad stack with one inverter added. The 12 inverter is a large sheet of galvanized metal and inverters bolted to it. This system is again starting it 6th year and still going strong.
I have used vented Outbacks and the 12 inverter The highest measured output 34,500 watts from a 40 kW peak array. The array is summer peaking.
I like the outback because of the flexibility, DC circuits, DC hybrid capability, AC coupling and I hope to use the new FNDC to enhance battery management. I am excited about the capability of the FNDC.
