Greg, couldn't you do this anyway? From Reno's description, it seems that the solar generation is cleaned up and synchronised by the inverter and effectively reverses your meter to credit you with your grid input. Your consumption runs the meter the opposite way to enable the PoCo to bill you for net use. So you can store whatever you like in batteries by plugging into any receptacle. That way, the solar array can generate at maximum potential regardless of your battery back-up load and you pick up all the Gummint promotional breaks. Most of the year you will only be trickle charging the batteries for make-up, and in fact the cost of same plus charger plus reinversion to ac will probably be more than a gasoline engine gennie backup over their respective lives.
