[TRNSYS-users] Very Simple IV Curve

Alexander,
There is an example that shows how to obtain an IV curve if you have
not already found it. It is located
in..\Trnsys17\Examples\Photovoltaics\IVcurve.tpf. The trick to the
example, I think, is that the simulation time is used as a proxy for the
load voltage. I am not entirely surprised that you are seeing some odd
behavior near the open circuit voltage and short circuit voltage points
as the mathematics of the PV model become very difficult to solve at
those points.
Kind regards,
David
