Review<BR><BR></FONT></DIV>
<BLOCKQUOTE dir=ltr style="MARGIN-RIGHT: 0px">Hi Tump,
<DIV><BR></DIV>
<DIV>However the FNDC has both functions. % start and volt and time
start.</DIV>
<DIV>So even if the % gets off for some reason, the volt/time should, repeat,
should start it.</DIV>
<DIV><BR></DIV>
<DIV>I have all but given up on the flexnet. I find for most customers
its too complicated, and while it gives good information, its hard for folks
to read.</DIV>
<DIV>And most importantly for me, the AGS function is not reliable. I
have had pretty good luck with the normal AGS, but when hooked to the the
FLEXNET just too unreliable.</DIV>
<DIV><BR></DIV>
<DIV>And heres the kicker. I talked to the techs at outback about a system
with a problem, and they told me there were having problems with the
flexnet and I should defeat it by setting the start/stop % to 0, great.</DIV>

Review<BR><BR></FONT></DIV><FONT size=3>Kent:<BR><BR>The manual is not
clear as to how this is done. Have you considered using a relay in
an FX inverter to activate the generator as is done in a system without
the Flex Net?<BR><BR>Interesting about the SMA claim, but until I hear

<BLOCKQUOTE class=cite cite="" type="cite">William,<BR><BR>In all of
these systems, the Mate's AGS system is being used to control the FNDC's
relay. The Mate's AGS port has been selected so that it operates
the FNDC's relay rather than using the Aux output on the inverter.
The FNDC is providing SOC info to the Mate, but isn't directly
controlling the relay.<BR><BR>I agree with you about the potential to
confuse customers. And about the inaccuracy of battery amp-hour
meters in general. But it is interesting that SMA's main claim
about the Sunny Island is that it does the best job managing
batteries. It does it by keeping track of the battery's
SOC.<BR><BR><BR>William Miller wrote: <BR>
<BLOCKQUOTE class=cite cite="" type="cite">Kent:<BR><BR>>From the
Flex Net DC manual, page 16: "OutBack strongly recommends using
the AGS function of the MATE to control a generator." I
assume from your post, you are using the Auto mode to have the relay
control a generator, a practice that the above quotation recommends
against. This may relate directly to your problems.<BR><BR>I
have no experience with the Flex Net but I took this opportunity to
review the manual more thoroughly than I have previously. My
conclusion is that the Flex Net is a great tool for the technically
inclined but offers a minimal convenience for the lay person.
The State of Charge function may be a more realistic method of
determining actual state of charge, but if it operates at all like the
E-meter or the Tri-Metric, it is prone to inaccuracy. The
variables associated with individual battery banks, particularly as
they age, make accurate calibration a moving target. Overall,
the Flex net has the potential to increase customer confusion with a
proliferation of synoptic (overly succinct) menus.<BR><BR>Again, I
call on the technicians in the industry to create a user interface
with the lay person in mind. See previous rant.<BR><BR>I may
find I recommend this system for remote locations so I can poll
statistics and interpret for the client, but I will not train a client
on the use of this unless he or she is particularly
inclined.<BR><BR>Anyone else have an opinion on the Flex net
system?<BR><BR>William Miller<BR><BR><BR><BR>At 12:13 PM 10/14/2009,
