I did some scouting about for what microinverters would be usable without a full professional install, for a small under half kilowatt playing around. I was hoping I could snap up some used enphases & try stuff out with a 200w panel & my existing batteries. But I really didn't turn up much; most discussion online made it seem like you needed special installer access to get anywhere with Enphase. Exciting to hear maybe this microinverter idea might not be totally dead in the water.
