I'm experimenting with setting up a pair of salvaged Enphase M215 micro-inverters with two Helios 260w PV solar panels. I also got the Enphase Envoy S internet gateway up and running to communicate with the inverters, commission them, and get them to export production information to the web! Part 1 of 2.
