Hi All!

Just became aware of these Enphase Microinverters (http://www.enphaseenergy.com/products/) and was wondering if anyone here has experience with them. since I have a very long cable run (~400ft (round trip) I was thinking that conversion to 240V AC at the PV source might be a good idea to minimize IR loss. What would be the advantage of this microinverter option vs. wiring up panels for 24V or 48V (more loss) and using a conventional MPPT controller and a standard pure sine wave inverter. Looks like you need one microinverter per PV panel (~$200 each) and for ~180W panel you can anticipate ~750ma @240V. If I am doing my math correct for a 15A AC branch circuit that would add ~$4000! (need ~15 inverters). What's the deal???

Thanks for any comments/ thoughts!
