[RE-wrenches] Smart grid grid-connected compatibility

[Doug Wells]

Kent,

I went through a similar situation with an Enphase system.  With a little discussion we decided that the easiest change is on the Utility side.  We encouraged the utility to put all solar systems with Smart metering on a different schedule.  Now the solar residence is only pinged at night when the frequency shift wont cause the inverters to drop out.
I wonder how many string inverters are doing the same thing but go unnoticed.  The Enlighten graphs make detection of this event very evident as it looks like a huge crash every day at the exact same time.
