Perhaps Cary has changed his mind. I will see if Cary will chime in to see what they are thinking now.

Of course, we're already under contract with REC Solar for a system with a central inverter -- but it's not going up until June 2010. Wonder if it's not too late to switch our system to a micro-inverter system. Again, REC tells me a micro-inverter system is still a lot more costly than a central inverter system. Of course, as I've noted before, if my central inverter konks at 12 years and has to be replaced then, and my micro-inverters last 20 years, you've got to add that cost in when comparing central to micro-inverters. With SMA going into micro-inverters, I have a feeling central inverters are going to out-moded within five or so years. What do you think? And/or what does John think?
