<P class=MsoNormal>I live in a TVA area where there is a Feed In
Tariff. Everything that is generated by the PV array feeds into the
grid through a Generation Meter that ties-in ahead of the house
meter. I have started getting calls from customers who hate having a
solar array that does not generate when the grid is down but the sun is
shining, but who also want to get the $.12 premium when the grid is
connected. We have lots of systems with SMA Sunnyboy inverters, but
more with Enphase micro-inverters. Rather than trying to reinvent
the wheel, what you found to be the best solution for this type of
installation?</P>
