<BR><BR><BR><FONT color=blue size=2 face=Arial>Gary,</FONT> <BR><FONT
size=3> </FONT> <BR><FONT color=blue size=2 face=Arial>I have been looking
at some AC coupled stuff lately. The "FSC" is propriatary to SMA, Sunny Island
to Sunny Boy. Pretty much anything else you need something to sense the
voltage of the battery bank so you can open a contactor on the AC line to the
Fronius when the battery voltage gets too high. Once the voltage drops the
contactor can close and bring the Fronius back on line and then the 5-minute
start up delay before it is feeding the line again.</FONT> <BR><FONT size=2
