<p>Amir,</p>
<p> It could have to do with the component order or a bad initial
temperature value. Click on the "control cards" icon in the
toolbar on the left and change to the "component order" tab, then
makes sure that the unit changing equation comes before the PV
panel in the input file order.</p>
<p>kind regards,</p>
<p> David</p>

<p>Hi</p>
<p>ّIm relatively new to trnsy.</p>
<p>I am trying to simulate the pv system but in the
elementary steps I faced a problem.</p>
<p>I'm getting weather data from Type109 and after
an equation I pass it to type 94a in kelvin, but I get the error
that the ambient temp is extremely low (below 50k), but when I
plot the equation output its in kelvin and logically above 50 (
I mean its definitely in kelvin not centigrade) !</p>
<p><br>
</p>
<p>The screenshots of the problem and plot is attached.</p>
<p><br>
</p>
<p>Thank all of you in advance.</p>
