Not very often, and usually for no more than an hour or two, although it
has been down as long as 5 days, either during tornado season, or ice
taking down power lines.  What these people are looking for is Just In Case
a big event happens.  They do not want to have all those panels just
sitting there.

Hi bill



Just how often is your grid down?

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?
