[RE-wrenches] Sonnen Battery & Outback Radian Inverter

[frenergy]

Mark,

             We humans many times make quite a stumble when we take a 
big new step (grid tied solar plus L-ion storage with the brains to 
manage all of it).  I agree with you on one hand, we'll probably 
screw-up the first few iterations.  On the other hand I feel pretty 
confident that my sensor laden, computer driven, signal processing, 
technology burdened truck will get me from point A to point B with few 
worries and for many miles.  I think we'll figure this out as there is a 
very powerful incentive to do so.
