I see. Can this function be enabled/diabled?

Hi Mark, Gary, 

The Xantrex XW series inverters will  do a frequency shift to cause most
models of grid-tied inverter to disconnect when the batteries are full,
while the system is operating in an ac coupled off-grid mode. The following
app-note describes this operation. 

Cheers, 

Mark

Gary, 
  
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.

Working on a proposal to add battery backup and a generator to an existing
10kW grid-tie system using the Fronius IG Plus 10.0 inverter.

Does anyone have any experience AC coupling this inverter to a Sunny Island
5048, or a Xantrex 6048? Is the Fronius capable of Frequency Shift control
(FSC) that comes from the battery-connected inverter?

Any other suggested solutions is appreciated.
