Amir,
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.
kind regards,
David
Hi
ّIm relatively new to trnsy.
I am trying to simulate the pv system but in the elementary steps I faced a problem.
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) !
The screenshots of the problem and plot is attached.
Thank all of you in advance.
