[TRNSYS-users] need help for simulating stand alone PV

[Diego A. Arias]

Dear Feng,

I am attaching a simple example that shows how to use Type48 and Type47 
for an off-grid system, and also a grid-connected system with inverter.  
A feature of the example is that the PV-module is using a maximum power 
tracker at all times.

I would recommend that you take a look at this example, and start from 
there to make your modifications, for example, replacing the maximum 
power point tracker with the resistance load.  Please make sure that you 
are running the latest version of TRNSYS (16.01.0003).  There was a 
change in Type194 that may conflict with previous versions of TRNSYS.

Best regards,

Diego
