<p class=MsoNormal><font size=2 color=blue face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:blue'>The SW lost its UL listing for Rev. 4.01
software around 2000. The GTI, used with Rev. 4.10 was relisted for
grid-interactive use. At least in our area, GT systems with pre-GTI SW's were allowed
to remain in service, as they were grandfathered in. However, no pre-GTI SW can
be used in a new GT application. It's not listed for GT operation any more.
What you are recommending can only be used by "getting away with it"
if an inspector or utility isn't aware of this history, but it's not
"legal".</span></font><o:p></o:p></p>

<p class=MsoNormal><font size=2 color=blue face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:blue'>Besides, while it's not cost-effective to
replace any SW's with more efficient GTFX's, I would not use a SW in a new GT
application anyway. They are an early technology and quite inefficient in GT use,
due to both the lack of a "silent sell" topology and their
fundamental us of the grid at night to maintain float voltage (thee are related
aspects of the same issue). According to posts here on this issue any years
ago, te SW is around 55% efficient overall in GT mode, if I recall correctly.</span></font><o:p></o:p></p>

inter tie for years, if the inverters were manufactured prior to I think 2001
then you do not need to have the gti box installed. If the guys on a
budget why spend the extra $$$$? Its not the most efficient it certainly
cheaper. </span></font><o:p></o:p></p>

wind side of an old off grid system that the new owner has brought the grid in.
He wants to grid tie the system. Another dealer is doing the solar side of
things.<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=3 face="Times New Roman"><span style='font-size:

with Outback 48 volt grid tie units and have the wind keep the battery up. Am I
correct that when the batteries are full from what ever source the outbacks
will grid connect and net meter any excess power to the grid? Seems that I
remember that they will but almost never get a call for grid tie up here in the
sticks so I figured I would ask the knowledge base.<o:p></o:p></span></font></p>

power.<o:p></o:p></span></font></p>
