[RE-wrenches] AC Coupling Fronius IG Plus 10.0 inverter

[Mark.Edmunds at schneider-electric.com]

Hi Mark,

The point of operation can be adjusted above normal battery operating 
levels, which essentially disables the feature.

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.
