<DIV><FONT face=Verdana color=#000080 size=2>Hello,David,I urgently want to get
your help.</FONT></DIV>
<DIV><FONT color=#000080>Following are the parameters I missed. </FONT></DIV>
<DIV><FONT color=#000080>Temperature coefficient of short circuit current =
0.0010 [1/k]</FONT></DIV>
<DIV><FONT color=#000080>Temperature coefficient of open circuit voltage =
-0.0038 [v/k]</FONT></DIV>
<DIV><FONT color=#000080>It's a mono-silicon based panel. All of the
parameters I sent to you are from the product manual. The test result of
open circuit voltage also matches that value. </FONT></DIV>
<DIV><FONT color=#000080>I also want to know which type I should use,
type194 or type194b? The parameters of Type194b's seem can be changed.
But a message " Only mode 1 has been implemented, mode 2 was
created for future updates" is showed in mode card. I'm not sure
whether it has been implemented now.</FONT></DIV>
<DIV>I have another question about the capacity of a battery bank. The
capacity of a battery bank will not vary with the number of cells in
series. So if it means that the cell capacity should vary with the number
of cells in series?</DIV>

<DIV><FONT face=Verdana size=2>Guangzhao,<BR> I also need to know the
temperature coefficient of short circuit current and the temperature coefficient
of open circuit voltage. Both of these should be listed on the manufacturer's
data sheet. Also, is this a silicon-based panel or some other material? The
reason I ask is that silicon cells typically run at about 0.5V per cell so 36 in
series would have an open cell voltage more like 18V than 21.5V. Its not
impossible of course.<BR>Kind regards,<BR> David<BR><BR><BR>On 3/8/2011

Questions about Type 194 and Type 665 </FONT></DIV>
<DIV></DIV>
<DIV><FONT face=Verdana size=2>Guangzhao,<BR> Could you please send me
an email containing the parameters that you are entering into the EES plugin
for Type194? I have run into some similar problems in the past and may be able
to help solve this one. It sounds from what you describe as though the problem
is in launching the plugin, not actually in having the plugin solve so perhaps
you only need to send me the Trnsys Studio project that causes the
error.<BR>Kind regards,<BR> David<BR><BR><BR>On 3/1/2011 00:47,

<DIV><FONT face=Verdana size=2>1. I encountered a problem when I was
trying to change the parameters of Type 194 using EES. A error "Missing
user function or improper format for Call statement" was showed after I
clicked on the icon on the parameter card. What's wrong with
it? </FONT></DIV>
<DIV>2. A convertible frequency air source heat pump is needed in
my model but I can't find one in TRNSYS. <FONT

Ok? </FONT></DIV>
