Windyboy on AC bus... [RE-wrenches]

[RE wrenches]

So... excited by the thought of a marriage between my two favorite
inverters, FX and SB, I am dreaming of this as a system for my next customer
that wants high performance grid tie AND backup - (of course UL listing
means I can get away with just an FX...) BUT this application also might be
interesting for wind - when Bergey finally gets their windyboy version of
the XL-1 online, I am assuming that I could plug it's output into the sub
panel (AC in) where it would grid tie in normal operation.  In a utility
outage it would back feed the FX powered sub panel, sharing loads, but what
if it exceeded the loads?  I assume it would push the voltage out of the
window and go into shutdown cycle....  too bad it couldn't charge the
batteries  when output exceeded usage (I guess an offboard charger would be
a clunky way to do this...).  In one of the Sunnyboy/FX posts there was
mention of using the 12V controller for something - What?
