Re: [TRNSYS-users] PV problem (type 94)



Fabrizio,
 I didn't see your original email so I didn't get a chance to look at the system. However, Type94 has two "power" outputs. One of them assumes that the PV is attached to a maximum power point tracker (MPPT). The other assumes that the PV is attached directly to a load voltage. In this second case, the power is the intersection point between the PV curve and the load curve. If you specify the load voltage input as 0 and look at the second power output, you'll see zero power. In most applications, PVs are attached to an MPPT so you can usually use the power at maximum power point output.
Kind regards,
 David

Dear Fabrizio,


Try to check the weather data input file, or try to plot the output of weather data component (type 109) if it is zero, may be that is the problem. So you have to defined the weather data file. If not then maybe you need to connect the controller to the battery and load.

dear all,
I've some problem with pv simulation:
When I simulate the configuration that I attach to you, the result of Energy power is zero.
I have linked total radiation between wether file and pv type 94.
Can anybody help me?
