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

[Matt Tritt]

Geoff,

Since we're going to soon be distributing the things I can't go blabbing
about how cool they are, yes I can! there is a line of 2.5 and 4.5 kW
multi-mode inverters soon to hit the market that 1: double as a wind
turbine controller, allows for multi-source inputs, provides up to 90%
efficiency from source to grid connection, works in grid-tie or
stand-alone, is field selectable for 50 or 60 Hz, has 110 split-phase
output in 60 cycle output, has full LCD display, has a 232 serial port
connection, takes up to 300 volt WT input and 420 v PV input, accepts
generator power, has a 48 VDC and 110 VDC versions, oh there I've said
too much! Oh yeah, they will have UL listing this month.

The really cool thing about these units (in my wind oriented way of
seeing) is that they provide everything you need in one box and are
highly efficient to boot. We're going to use them with our Eoltec 6 kW
turbines for sure.

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?
