Non-Enphase micro-inverter comparisons/thoughts?

runningduck

A couple of years ago I did a small grid-tie project using Enphase micro-inverters. Since then a number of other manufactures have come out with their own micro-inverters (Encysys, Power One etc.) but I haven't been able to find much information about how they compare to Enphase's offerings. All of them seem very similar to Enphase system (as would be expected) but there are some differences which might be compelling in the right circumstance. Has anyone had any experience with micro-inverters other then Enphase? Has anyone else been able to find any substantive review/comparison between Enphase and any of the other offerings now available?
