our power outages generally come from bad weather too... and of course when the weather is bad the pv does next to nothing. so for emergency backup, i recommend a generator. todd On Friday, April 26, 2013 10:33am, "Bill Turberville" <billt...@ece-llc.com> said:
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.

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? W.C. (Bill) Turberville P.E.
